Urbanization and climate change are amongst the greatest challenges of the 21st century. In the "Low Carbon Future Cities" project (LCFC), three important problem dimensions are analysed: current and future GHG emissions and their mitigation (up to 2050); resource use and material flows; and vulnerability to climate change.
The industrial city of Wuxi has been the Chinese pilot city of the project. To establish the pathway for a low carbon future, it is crucial to understand the current situation and possible future developments. The paper presents the key results of the status quo analysis and the future scenario analysis carried out for Wuxi. Two scenarios are outlined. The Current Policy Scenario (CPS) shows the current most likely development in the area of energy demand and GHG emissions until 2050. Whereas the extra low carbon scenario (ELCS) assumes a significantly more ambitious implementation, it combines a market introduction of best available technologies with substantial behavioural change. All scenarios are composed of sub-scenarios for the selected key sectors.
Looking at the per capita emissions in Wuxi, the current levels are already high at around 12 tonnes CO2 per capita compared to Western European cities. Although Wuxi has developed a low carbon plan, the projected results under current policies (CPS) show that the total emissions would increase to 23.6 tonnes CO2 per capita by 2050. If the ELCS pathway was to be adopted, these CO2 emission levels could be reduced to 6.4 tonnes per capita by 2050.
Our perception of design is changing, for design today is no longer concerned only with aesthetics. Now the key factors are interdisciplinary competence and approaches to problem solving. Both politicians as well as businesses recognise design's hybridity and increasingly implement it as a driver of sustainable development (see Chap. 2: Design as a Key Management Factor for Sustainability).
But what exactly does "sustainability" mean? What does it mean in this specific context? People must make use of natural resources to meet their basic needs. In this process, resources are transferred into commercial circulation and usually transformed into products with a particular function. Yet the environment is limited and humanity uses more resources than the Earth can sustainably provide. It is time to rethink and generate the same usage while consuming fewer resources (see Chap. 3: Environmental Space - Challenging Transitions).
Most countries have incorporated sustainability strategies into their political agendas in order to counteract the threats of climate change caused by the overuse of natural resources, high CO2 emissions, and other factors. The indicators for these strategies vary greatly from country to country (see Chap. 4: Sustainability - Challenges, Politics, Indicators).
These indicators need to be taken into account if we are to successfully implement a product or service within a specific context. A concept can only be successful when country-specific indicators are taken into account and the societal context is incorporated into the plan right from the start. The goal is to develop services that support national sustainability targets in production and consumption systems (see Chap. 5: Managing Sustainable Development).
When it comes to companies, these changes can simply be introduced in the form of services or products. In the end, it is the users who decide on the success or failure of innovative solutions by either integrating them into their daily lives or ignoring them. Solutions will only be integrated into users' lives when their role within the social framework remains unchallenged by behavioural transformations caused by use of the solution. In order for users to be able to adopt innovations, sustainable development must take place simultaneously on many different levels. These multi-levelled transitions allow for the transformation of society as a whole. Designers can act as agents of change by providing the needed innovations (see Chap. 6: Transition Requires Change Agents for Sustainability).
If we are to develop suitable solutions and new approaches, the real needs have to be analysed at the beginning of the development process. New physical products, which frequently result in auxiliary products, are often developed without taking into account the overall context, whereas the development of service-orientated solutions is ignored. A physical product is not absolutely necessary. A service (which is naturally dependent on physical products) can usually fulfil the need just as well - or perhaps even better and at a lower cost – while using fewer or no resources (see Chap. 7: Needs & Services - An Approach). There are a variety of possible approaches to integrate sustainability into the design process (see Chap. 8: Design Process).
Precisely which solution is "most or more sustainable" (this is dependent on the defined targets and the indicators used) is often not immediately obvious, and we must turn to a set of methods for a transparent and tangible assessment (see Chap. 9: Sustainability Assessment in Design - Overview and Integration of Methods).
On 8 November 2016, Donald Trump was elected to become the 45th President of the United States of America. In his campaign, he repeatedly expressed his intention to "cancel the Paris Agreement". How can the course set with the adoption of the Paris Agreement be continued independently of the developments in the US? The authors sketch possible consequences of the sea change of US climate policy for the international negotiation process and identify options for a "Trump-resilient" way forward.
As many other countries, Germany misses to exploit most of its large potential for cost-effective energy efficiency improvements. An organisation collecting funds and allocating them to the most (cost-)effective programmes could be a solution.
Therefore, political parties and trade unions as well as environmental NGOs have called for the creation of such an Energy Efficiency Fund. A recent study by the Wuppertal Institute together with a number of partners, commissioned by the Hans Böckler Foundation, analysed the feasibility of such an institution.
It has been the objective of the project, completed in March 2005, to
identify the added value of an Energy Efficiency Fund,
develop concrete proposals for the institutional setting and the financing of an Energy Efficiency Fund in Germany,
prepare and assess the benefits and costs of a portfolio of innovative but realistic energy efficiency programmes and campaigns, which the Energy Efficiency Fund would implement,
identify the effects of the fundraising and the programmes on different industries, particularly on the suppliers of energy-efficient technologies and services, and on their growth and employment perspectives,
estimate the net employment effects of such an Energy Efficiency Fund and its activities.
This paper presents the results and assesses the usefulness of the project and the participatory elements for increasing the acceptance of such a policy instrument.
The European Horizon 2020-project COMBI ("Calculating and Operationalising the Multiple Benefits of Energy Efficiency in Europe") aims at estimating the energy and non-energy impacts that a realisation of the EU energy efficiency potential would have in the year 2030. The project goal is to cover the most important technical potentials identified for the EU27 by 2030 and to come up with consistent estimates for the most relevant impacts: air pollution (and its effects on human health, eco-systems/crops, buildings), social welfare (including disposable income, comfort, health and productivity), biotic and abiotic resources, the energy system and energy security and the macro economy (employment, economic growth and the public budget). This paper describes the overall project research design, envisaged methodologies, the most critical methodological challenges with such an ex-ante evaluation and with aggregating the multiple impacts. The project collects data for a set of 30 energy efficiency improvement actions grouped by energy services covering all sectors and EU countries. Based on this, multiple impacts will be quantified with separate methodological approaches, following methods used in the respective literature and developing them where necessary. The paper outlines the approaches taken by COMBI: socio-economic modelling for air pollution and social welfare, resource modelling for biotic/abiotic and economically unused resources, General Equilibrium modelling for long-run macroeconomic effects and other models for short-run effects, and the LEAP model for energy system modelling. Finally, impacts will be aggregated, where possible in monetary terms. Specific challenges of this step include double-counting issues, metrics, within and cross-country/regional variability of effects and context-specificity.
Addressing food waste prevention is one target of the Sustainable Development Goals (SDGs) and a major task for the UN Environmental Programme and the European Commission. It is promising in terms of its environmental saving potential. However, it also leads to consumers being able to save money, which they then are likely to spend, thus again causing a negative environmental impact. This dimension of the so-called indirect rebound effect, which prevents the desired ecological benefits from being achieved, is investigated in this paper. By using a single-region environmentally extended input-output model from a production perspective, the indirect rebound effects from food waste prevention in Germany are analysed. Any political action needs to consider not only a differentiation in income class, but also alternative concepts such as the principles of sufficiency in order to achieve all ecological benefits and specifically the third target of SDG 12.
Despite Germany's Paris Agreement pledge and coal exit legislation, the political debate around carbon-intensive coal remains heated. Coal power and mining have played an important, yet changing role in the history of German politics. In this paper, we analyze the entire parliamentary debate on coal in the German parliament (Bundestag) from its inception in 1949 to 2019. For this purpose we extract the more than 870,000 parliamentary speeches from all protocols in the history of the Bundestag. We identify the 9167 speeches mentioning coal and apply dynamic topic modeling – an unsupervised machine learning technique that reveals the changing thematic structure of large document collections over time - to analyze changes in parliamentary debates on coal over the past 70 years. The trends in topics and their varying internal structure reflect how energy policy was discussed and legitimized over time: Initially, coal was framed as a driver of economic prosperity and guarantee of energy security. In recent years, the debate evolved towards energy transition, coal phase-out and renewable energy expansion. Germany’s smaller and younger parties, the Greens and the Left Party, debate coal more often in the context of the energy transition and climate protection than other parties. Our results reflect trends in other countries and other fields of energy policy. Methodologically, our study illustrates the potential of and need for computational methods to analyze vast corpora of text and to complement traditional social science methods.
In order to make our lifestyles sustainable, changing our consumption patterns is fundamental. Hence, we need to better understand who the "consumers" are and to consider them as an active actor to directly engage for ensuring effective policies. In order to support a resource-light society, production and consumption need to be considered through an integrated system view; within this, consumers play an important role as co-acting subjects. Almost every activity in private life involves a form of consumption aimed at satisfying the subject's needs and often regarded through an economic lens. Sustainable development is not about abolishing private consumption, but rather about making it environmentally, socially and individually sustainable in its design, organization and realization, also involving ideas of simplicity or renunciation. In this paper, we will assess the status quo of the German and European debates on Consumer Research Policies and discuss the idea to link sustainability research and consumer research - where a strategic relation is currently missing. Within that discussion, an evidence-based and obligatory consumer research strategy in Germany and Europe would represent a significant improvement. A system view perspective is necessary to take into consideration the impressive amount of diversity, and to elaborate realistic economic and consumer policies. Therefore, we propose nine steps for understanding the role of the consumer in implementing sustainable development from a scientific and political perspective. The limitations of this paper are thus a result of the very diverse and often unclear policies and agendas produced by governments. The implementation of the proposed innovative research agenda for a future-orientated and sustainability-based consumer research is not free from challenges. Still, the paper suggests the first steps towards this direction. After a critical discussion of the current EU and German consumer and sustainability policies, nine differentiated and substantial ways to integrate and ameliorate them are proposed.
Although smart energy technologies (SETs) can fulfill multiple tasks in increasingly decarbonized and digitalized energy systems, market diffusion is still limited. This study investigates which beliefs influence consumers' intention to adopt two smart-energy offerings, whether the rapid growth of the smart home market will now drive SET adoption, and if consumer-driven diffusion will lead to sustainability potentials being realized. Building on UTAUT2, a new theoretical model is proposed, and a consumer acceptance survey was conducted in Germany (n = 700). Results indicate that a growing smart home market will not increase SET adoption and that "adjustable green defaults" should be introduced.
Article 6 of the Paris Agreement establishes three approaches for countries to cooperate with each other in implementing their climate protection contributions. However, Article 6 sketches out only some basic contours; the details are to be filled in by further negotiations. This article surveys the views countries have submitted so far in order to identify the main issues at stake, points of controvery and convergence and possible ways forward. The submissions reveal some sharp differences in opinions on key issues such as the scope of the new mechanisms, how to operationalise the Article 6 requirement to increase ambition, whether to have international provisions on the promotion of sustainable development, and how to protect environmental integrity in the use of Article 6. The article concludes with a number of recommendations on how to address these controversies.
What role do transaction costs play in energy efficiency improvements and how can they be reduced?
(2019)
Ex-ante policy evaluation requires a detailed understanding of how the subjects addressed by the policy react to its implementation. In the context of energy efficiency, policy measures typically aim at influencing investment decisions towards more efficient options.
As has been discussed widely in the context of the "energy efficiency gap", investments in energy efficiency improvements are frequently not conducted even though they seem cost-effective from a simple cost-benefit perspective, where transaction costs have been identified as one important barrier.
While transaction costs have been discussed widely from a conceptional perspective, empirical studies quantifying transaction costs and measures to reduce them are rare. This paper presents approaches, results and insights from a recently completed research project funded by the German Federal Energy Efficiency Center (BfEE), addressing transaction costs in various energy efficiency measures and the role of energy efficiency services to overcome the barrier.
We analyse a set of 11 energy efficiency investments covering private households, public institutions and the industry sector. We gather data on direct investment costs and energy cost savings and provide a detailed analysis of the various barriers and transaction costs associated with the implementation. We then analyse the costs of existing energy efficiency services using data provided by the BfEE. We compare the different cost elements and analyze the potential of energy efficiency services to reduce transaction costs.
We find that the role of transaction costs differs substantially between households, public institutions and companies and that the impact of energy efficiency services on transaction costs needs to be evaluated using different methodological approaches. We conclude that while data availability on disaggregated transaction costs is a major challenge, energy services can reduce transaction costs considerably.
Many hope that the Global Stocktake under the Paris Agreement can become a catalyst for increased mitigation ambition over time. Based on different theories of change, this paper outlines four governance functions for the Global Stocktake. It can contribute to the Paris Agreement as a pacemaker (stimulating and synchronizing policy processes across governance levels), by ensuring accountability of Parties, by enhancing ambition through benchmarks for action and transformative learning, and by reiterating and refining the guidance and signal provided from the Paris Agreement. The paper further outlines process- and information-related preconditions that would enable an ideal Global Stocktake.
What makes a good policy? : Guidance for assessing and implementing energy efficiency policies
(2013)
Which factors are crucial to successfully design and implement a "good practice" policy to increase the energy efficiency of buildings and appliances? This is one of the main challenges for the new web platform bigee.net that provides guidance on good practice policies.
In this paper we examine the question what "good practice" is by presenting a multi-criteria assessment scheme to analyse different policies worldwide.
The assessment scheme contains a set of criteria addressing key factors leading to the success of a policy as well as its outcomes: a good policy addresses all market players and barriers, avoids lost opportunities and lock-in effects, has ambitious and regularly updated energy efficiency levels, and spill-over effects. Other criteria are high energy savings and the calculated cost-effectiveness.
The assessment scheme provides a standardised data collection approach, which paves the way for both qualitative and quantitative evaluation. Furthermore, it can help policy-makers to transfer a successful policy.
The development of the scheme is based on a literature review of worldwide implemented policies and measures that promote energy-efficiency of buildings and appliances. Criteria were operationalized, including a ranking between 0 and 10. The ranking is a decisive factor whether the policy qualifies as good practice. To demonstrate the practicability of this scheme, the paper analyses a good practice example according to the assessment scheme: Energy-Efficient Refurbishment and Energy Efficient Construction programmes of the German public bank KfW.
What leads to lunch : how social practices impact (non-)sustainable food consumption / eating habits
(2017)
The field of nutrition will face numerous challenges in coming decades; these arise from global consumption patterns and lead to a high use of resources. Actors in the catering sector face difficulties in promoting their solutions for a more sustainable situation in their field, one of them being the lack of acceptance from consumers. We must ask the question of how to influence consumer behavior and bring forth a transition towards more sustainable food consumption. This paper presents results of a qualitative assessment of eating practices. A group of ten consumers participated in problem-centered interviews and provided data on their eating-out behavior over the course of two weeks. Using the theoretical approach of practice theory, the data gathered in this study were used to form an understanding of the practice of eating out with a focus on the daily routines that influence consumer choices. The results indicate that the practice of eating out is highly dependent on external factors. Busy lifestyles, mobility routines and a perceived lack of time prompt the decision to eat out. Consumers consciously do so to save time and effort and to streamline their schedules. Mobility seems to be an important driver for eating out. Participants try to limit the ways they undertake eating out yet often stop for a meal in-between appointments spontaneously. Findings suggest that nutrition knowledge and sustainable mindsets have little influence on the eating decisions away from home: Participants show a high level of distrust towards quality claims and put their health concerns aside eating out. We can conclude that the act of eating out is strongly influenced by daily routines and those practices that precede or succeed it. Changes in work and mobility patterns are very likely to have an impact on the way consumers eat away from home.
Renewable energy targets in the European Union (EU) have raised the demand for timber and are expected to increase dependence on imports. However, EU timber consumption levels are already disproportionally high compared to the rest of the world. The question is, how much timber is available for the EU to sustainably harvest and import, in particular considering sustainable forest management practices, a safe operating space for land-system change, and the global distribution of "common good" resources. This article approaches this question from a supply angle to develop a reference value range for the current as well as future sustainable supply of timber at the EU-27 and global levels. For current supply estimates, national-level data on forest area available for wood supply, productivity in that area, as well as the rate available for harvest were collected and aggregated into three potential supply scenarios. For future supply estimates, a safe operating space scenario halting land use change, a sensitivity analysis, and a literature review were performed. To provide both a comparison of global versus EU sustainable supply capacities and to develop a benchmark toward evaluating and comparing levels of consumption to sustainable supply capacities, per capita calculations were made. Results revealed that the per capita sustainable supply potential of EU forests is estimated to be around three times higher than the global average in 2050. Whether a global or EU reference value is more appropriate for EU policy orientation, considering both strengthened economic and cultural ties to the forest in forest-rich countries as well as the need to prevent problem shifting associated with exporting land demands abroad, is discussed. Further research is needed to strengthen and harmonize data, improve methods for modeling future scenarios and incorporate interdisciplinary and multi-stakeholder perspectives toward the development of robust and politically relevant reference values for sustainable consumption levels.
The 2015 Paris Agreement relies on Nationally Determined Contributions (NDCs) to outline each country's policies and plans for reducing greenhouse gas (GHG) emissions. To strengthen global climate action and achieve the Agreement's temperature goal, it is crucial to enhance the ambition level of NDCs every 5 years. While previous studies have explored the ambition of initial NDCs, limited research has delved into the factors driving the enhancement or lack thereof in NDCs' emission reduction plans. This study employs a mixed-method design to investigate the determinants of NDC enhancement. First, we analyse the updated or revised NDCs of 111 countries using quantitative methods. Second, we conduct qualitative case studies focusing on Brazil and South Africa. Our findings reveal that countries that engaged in stakeholder consultations with civil society, business, and labour groups prior to developing their updated or revised NDCs were more likely to enhance their greenhouse gas reduction targets. These results are further supported by the case studies. South Africa conducted comprehensive consultations and submitted an enhanced GHG target, while Brazil, which did not arrange open consultations, did not improve its target. This study underscores the significance of comprehensive and transparent stakeholder engagement processes, highlighting their potential to drive enhanced NDCs. By involving diverse stakeholders, including civil society, business, and labour groups, countries can foster greater ambition and effectiveness in their climate action, ultimately contributing to the global effort to combat climate change.
The circle is a ubiquitous metaphor in the current scientific and political debate on possible strategies for coping with the changes brought by the so-called "Anthropocene". Terms such as "recycling", "upcycling", "downcycling", "life cycle" or "circular economy" all refer to the same geometric shape, which in turn can be found in numerous diagrams illustrating the respective design approaches and political strategies. But how does the circle shape the way we think and act as designers? Is it an appropriate metaphor to guide us to feasible actions, or is its degree of simplification too far removed from reality? In this article we look at the circular economy as a designed model, and question the circle as a communication tool for the cultural project of sustainability. As the circle may carry the risk of an oversimplified, unattainable, even disillusioning ideal, we discuss various alternative images and forms for their potential to become metaphors of alternative models. The hole, the plate, the pasture, the wheel, the mill wheel, the hamster wheel, the vortex, the double helix, the spider web and the rhizome - as metaphors, they each open up different perspectives and approaches to reality, they each construct different relationships and dependencies between nature and culture. The aim of this article is less about postulating the end of the circle as a metaphor in the sustainability debate, as it is about to fathom the circle's ends as a metaphorical tool. In other words, when does the metaphor of the circle become too abstract? As designers we can say that falling in love with a form right at the beginning of a design process can be rather limiting, as hardly any alternatives will be considered, and all further decisions are subordinated to achieving the desired shape. Therefore, we would like to emphasise the contingency of the circular economy as a model. We would like to welcome the thought that the circle has an "end".
How do recent changes in consumption in the wake of the COVID-19 pandemic affect the avoidance of packaging waste? How can an increase in packaging waste be countered and the previous trend towards unpackaged and reusable solutions be revived and promoted?
To tackle these questions, we use a systemic approach that regards packaging as a network of interrelated interests of industry (manufacturing and logistics), trade (retail and catering), consumers and the waste management sector. To analyse this network, we applied three methods. First, we analysed secondary sources such as surveys. Second, we conducted semi-structured interviews with seven actors from industry, consumer education and waste management in May and June 2020. Third, we used the questions from the interview guideline to do an online survey among representatives of the public waste management industry.
Water and energy are two pivotal areas for future sustainable development, with complex linkages existing between the two sectors. These linkages require special attention in the context of the energy transition. Against this background, this paper analyses the role of water availability in the development of solar thermal and photovoltaic power plants for the case of the Draa Valley in southern Morocco. Located in a semi-arid to arid mountainous area, the Drâa Valley faces high water stress - a situation expected to worsen due to climate change. At the same time, the region has one of the greatest potentials for solar energy in the world. To examine whether limited water availability could accelerate or delay the implementation of solar thermal and photovoltaic power plants, this paper compares regional water availability and demand in the Draa Valley for different scenarios, paying particular attention to potential socio-economic development pathways. The Water Evaluation and Planning System software is applied to allocate the water resources in the study region. The water supply is modelled under the Representative Concentration Pathway 8.5 climate scenario, while the water demand for the Drâa Valley is modelled for a combination of three socio-economic and two energy scenarios. The climate scenario describes a significant decrease in water availability by 2050, while the socio-economic and energy scenarios show an increase in water demand. The results demonstrate that during a sequence of dry years the reservoirs water availability is reduced and shortages in water supply can result in high levels of unmet demand. If this situation occurs, oasis farming, water for drinking and energy production could compete directly with each other for water resources. The energy scenarios indicate that the use of dry cooling technologies in concentrated solar power and photovoltaic hybrid systems could be one option for reducing competition for the scarce water resources in the region. However, given that energy generation accounts for only a small share of the regional water demand, the results also suggest that socio-economic demand reduction, especially in the agricultural sector, for example by reducing the cultivated area, will most likely become necessary.
In this brochure, WISIONS focuses on the interdependent connection between water and energy. WISIONS presents good practice projects dealing with water and energy in Guatemala, Peru, Tunisia, the Philippines and Tanzania that have been successfully implemented, with the intention of further promoting the particular approaches used by these projects. Using a key number of internationally accepted criteria, the main consideration for the selection of the projects was energy and resource efficiency. The assessment of the projects also included the consideration of regional factors acknowledging different needs and potentials.
Electricity generation requires water. With the global demand for electricity expected to increase significantly in the coming decades, the water demand in the power sector is also expected to rise. However, due to the ongoing global energy transition, the future structure of the power supply - and hence future water demand for power generation - is subject to high levels of uncertainty, because the volume of water required for electricity generation varies significantly depending on both the generation technology and the cooling system. This study shows the implications of ambitious decarbonization strategies for the direct water demand for electricity generation. To this end, water demand scenarios for the electricity sector are developed based on selected global energy scenario studies to systematically analyze the impact up to 2040. The results show that different decarbonization strategies for the electricity sector can lead to a huge variation in water needs. Reducing greenhouse gas emissions (GHG) does not necessarily lead to a reduction in water demand. These findings emphasize the need to take into account not only GHG emission reductions, but also such aspects as water requirements of future energy systems, both at the regional and global levels, in order to achieve a sustainable energy transition.
In this second brochure, WISIONS aims to focus on the significance of a combined approach to water and energy and to present a number of projects from around the globe that have been successfully implemented, with the intention of further promoting the particular approaches used by these projects. Using a key number of internationally accepted criteria, the main consideration for selection of the projects was energy and resource efficiency, but social aspects such as the inclusion of local population were also of relevance. The assessment of the projects also included the consideration of regional factors acknowledging different needs and potentials.
Wasting food, wasting resources : potential environmental savings through food waste reductions
(2018)
Food is needed to maintain our physical integrity and therefore meets a most basic human need. The food sector got in the focus of environmental policy, because of its environmental implications and its inefficiency in terms of the amount of food lost along the value chain. The European Commission (EC) flagged the food waste issue a few years ago and adopted since then a series of policies that partially address the problem. Among these, the Resource Efficiency Roadmap set the aspirational goal of reducing the resource inputs in the food chain by 20% and halving the disposal of edible food waste by 2020. Focusing on consumer food waste, we tested what a reduction following the Roadmap's food waste target would imply for four environmental categories in EU28 (European Union 28 Member States): greenhouse gas emissions, land use, blue water consumption, and material use. Compared to the 2011 levels, reaching the target would lead to 2% to 7% reductions of the total footprint depending on the environmental category. This equals a 10% to 11% decrease in inputs in the food value chain (i.e., around half of the resource use reductions targeted). The vast majority of potential gains are related to households, rather than the food-related services. Most likely, the 2020 target will not be met, since there is insufficient action both at Member State and European levels. The Sustainable Development Goals provide a new milestone for reducing edible food waste, but Europe needs to rise up to the challenge of decreasing its per capita food waste generation by 50% by 2030.
A future-oriented and sustainable "Leasing Society" is based on a combination of new and innovative serviceoriented business models, changed product and material ownership structures, increased and improved eco-design efforts, and reverse logistic structures. Together these elements have the potential to change the relationship between producers and consumers, and thereby create a new incentive structure in the economy regarding the use and re-use of resources. While the consumer in a leasing society buys a service (instead of a product), the producer in a leasing society retains the ownership of the product (instead of selling it) and sells the service of using the product. This creates producer incentives to re-use, remanufacture, and recycle products and materials and could become a cornerstone of the circular economy, depending on how the leasing society is implemented. While a predominantly positive picture of the success of a leasing society model and related business cases emerges from the bigger part of the available literature, this paper argues that the resource efficiency of respective business cases is highly dependent on the specific business case design. This paper develops a more cautious and differentiated definition of the leasing society by discussing relevant mechanisms and success factors of leasing society business cases. The leasing society is discussed from a micro business-oriented and a macro environment-oriented perspective complemented by a discussion of conditions for successful business models that reduce environmental impacts and resource footprints.
This report analyses the international climate negotiations at the UN climate conference in Warsaw in November 2013. The report covers the discussions under the Durban Platform on developing a new comprehensive climate agreement by 2015 and increasing short-term ambition as well as the issues relating to near-term implementation of previous decisions in the areas of emission reductions and transparency, adaptation, loss and damage, finance and technology. The report concludes that Warsaw once again starkly highlighted the sharp divisions and lack of trust among countries. Industrialised countries' collective lack of leadership strongly contributed to re-opening the traditional North-South divide. As a result, on many issues the outcomes hardly go beyond the lowest common denominator. The conference only agreed on the bare minimum to move the 2015 process forward and also made no headway in strengthening short-term ambition. Some progress was made with the establishment of the "Warsaw international mechanism for loss and damage associated with climate change impacts" and the completion of the rules for reducing emissions from deforestation and forest degradation. However, here as well further substance, in particular financial support from industrialised countries, is required to actually fill these mechanisms with meaning. If countries want to escape from groundhog day, they will have to start seeing and utilizing the UN climate process rather differently.
Vision development towards a sustainable North Rhine-Westphalia 2030 in a science-practice-dialogue
(2017)
The paper presents the results of a participatory vision development process in the Federal State of North Rhine-Westphalia (NRW) in Germany. The vision development was part of a scientific research project that accompanied the development of a sustainability strategy for NRW at state level. The Sustainability Strategy NRW was adopted in July 2016 and contains parts of the vision developed in the research project: Sentences from the narrative text vision and proposed targets and indicators that back-up the vision for a sustainable NRW in 2030 were used by the state of NRW. The vision was developed in iterative steps in three consecutive dialogue rounds with different stakeholders from science and practice. The paper presents the methodological approach and the results of the vision formulation process. The paper discusses the lessons learned from the vision development - from both practical and theoretical perspectives of transition management. The paper explores the relevance of setting ambitious targets for sustainable development as part of a state strategy by taking the proposed target of a "4 × 25% modal split" by 2030 as an example. The project demonstrated that a participatory approach for vision development is time and resource consuming, but worth the effort as it improves the quality and acceptance of a vision. Furthermore, the project demonstrated that transformative science contributes valuable inputs for sustainability transitions and for facilitating participatory vision development.
This report focuses on the contribution of ICT to improvements in resource efficiency and transport intensity at the macro, meso and micro levels. It presents the research on environmental effects of e-business and e-work.
The research strand explored the implication of ICT and its applications from the micro- (case study), meso- (different e-business types) and macro-level (macro-economic and policy level).
The "macro-analysis-module" aimed at quantifying the potential contribution of e-business and ICT to dematerialisation and resource productivity. The analysis followed a top-down approach complementary to the case study based microanalyses. It compromised the analysis of energy-use and selected material flows (CO(2)) of three EU Member States to determine whether there is any macro-level evidence of dematerialization and increased resource productivity resulting from e-business and ICT.
From a micro and meso level perspective, the research object has been the provision of new IT based applications instead of "traditional" products, services and customs (e-commerce and telework). The research quantified the resource- and transport efficiency of e-business in different case studies and identified key factors determining the impact on resource- and transport efficiency.
The ultimate goal of German Resource Efficiency Programme (ProgRess) is to make the extraction and use of natural resources more sustainable and reduce associated environmental pollution as much as possible. By doing this - also with responsibility towards future generations - the programme should create a prerequisite for securing a long-term high quality of life. To bring the policy approaches formulated in ProgRess to reality, efforts to implement resource efficiency measures have to be increased at all levels - from international to regional to local.
The chapter intends to provide an impetus for the current debate on ProgRess policy development. The chapter identifies, analyses and describes deficits and possibilities of vertical integration of the German programme in particular and derives recommendations for action which may also serve as indications for other strategies. The following sections are based on results of the advisory report "Vertical integration of the national resource efficiency programme ProgRess (VertRess)", conducted by the German Institute of Urban Affairs (Difu) and the Wuppertal Institute for Climate, Environment and Energy on behalf of the German Environmental Agency (UBA) and the Federal Ministry of the Environment, Nature Conservation and Nuclear Safety (BMU).
An increasing number of publications about theoretical approaches and new findings illustrate the relevance of the topic environmental risk assessment. The actual discussion about high oil prices is not incorporated under this headline; but it should be, as natural resource scarcity is a crucial economic factor. In practical experience, more and more banks, insurance companies as well as investors realize that there are certain areas with a high correlation between sustainable development and corporate success, corporate risk exposure and corporate performance. In this discussion one of the most obvious topics are risks related to climate change. According to the findings of surveys evaluated in this paper climate change starts to affect economic development and companies' performance in various ways. Over the next decade, economic losses due to climate change are estimated by US$ 150 billion per year. As result world's business leaders have described climate change as the biggest challenge of the 21st century. Hence, the incorporation of climate change as a risk factor is essential, but risks related to climate change feature a severe issue of complex structure and uncertainty; traditional risk assessment tools appear in the light of not being able to either reflect the multifaceted system nor provide sufficient outcomes. Environmental risk assessments in general so far have mainly emphasized - if at all - on actual and possible impacts of the release of materials or emissions (external effects). But an overall sustainable risk assessment has also to take into account the risks related to the inflow of materials. The main reason for neglecting the inflow risks from an environmental perspective can be seen in the fact that these risks seem to be less tangible and more uncertain. Nevertheless, in a world where economic development and the use of natural resources is not uncoupled yet, a steadily increasing economic power will result in a continually rising extraction of resources. As all resources are limited, the risk of scarcity will rise; and the example of water illustrates that it already exists. Indeed, scarcity is not tangible for all kind of resources from a present point of view. Hence, a specified analysis is needed considering different market and supply conditions. A comprehensive analysis of environmental risks needs to encompass risks affecting the output as well as the input side of a value chain. This paper enlarges the discussion on environmental risk assessments upon the input dimension using the example of carbon risks. Firstly, carbon risks are defined as risks related to climate change at the corporate level with a focus on the input as well as the output dimension. Secondly, an analysis of the current discussion on the topic of carbon risk evaluates the status quo of scientific work in this field. Thirdly, in terms of developing a practically oriented tool, the Value-at-Risk approach and it's application to measure input oriented carbon risks are scrutinized. The results discuss how future volatility and market prices can be utilized to describe the uncertainty resulting from markets acknowledging and pricing oil scarcity as a risk factor. Finally recommendations with a focus on strategic management decisions and financial performance analysis are given and further research opportunities are drawn. The conclusion is; once markets have acknowledged the depletion mid-point as a measure of oil scarcity, natural scarcity will result in a significant higher Value-at-Risk. The Value-at-Risk of one barrel of crude oil could then be as high as US$ 15.5 in the short term and even US$ 17.2 in the long term. The scope of this paper is neither intended to predict one likely development nor to demonstrate how this tool can actually work in terms of forecasting single companies' performance. But in order to point the way ahead, this paper provides scenarios for potential future developments and sets a frame for risk assessments due to oil scarcity.
For some time, 3D printing has been a major buzzword of innovation in industrial production. It was considered a game changer concerning the way industrial goods are produced. There were early expectations that it might reduce the material, energy and transport intensity of value chains. However for quite a while, the main real world applications of additive manufacturing (AM) have been some rapid prototyping and the home-based production of toys made from plastics. On this limited basis, any hypotheses regarding likely impacts on industrial energy efficiency appeared to be premature. Notwithstanding the stark contrast between early hype and practical use, the diffusion of AM has evolved to an extent that at least for some applications allows for a preliminary assessment of its likely implications for energy efficiency.
Unlike many cross-cutting energy efficiency technologies, energy use of AM may vary substantially depending on industry considered and material used for processing. Moreover, AM may have much greater repercussions on other stages of value chains than conventional cross-cutting energy efficiency technologies. In case of AM with metals the following potential determinants of energy efficiency come to mind:
- A reduction of material required per unit of product and used during processing;
- Changes in the total number and spatial allocation of certain stages of the value chain; and
- End-use energy efficiency of final products.
At the same time, these various streams of impact on energy efficiency may be important drivers for the diffusion of AM with metals. This contribution takes stock of AM with metals concerning applications and processes used as well as early evidence on impacts on energy efficiency and combine this into a systematic overview. It builds on relevant literature and a case study on Wire Arc Additive Manufacturing performed within the REINVENT project.
Using results-based finance for climate action : existing initiatives and the role of the CDM
(2014)
Results-based finance is receiving increasing attention, being considered as a potential key funding mode in climate finance. The Clean Development Mechanism has been cited to potentially contribute to this goal. Against this background, the policy brief outlines the rationale of the concept and analyses six climate change mitigation initiatives that build on the results-based finance approach. The analysis puts a special focus on the role of the CDM.
Nowadays, high expectations are set for a digitally enabled circular economy (CE), to enhance resource efficiency. Tracing, tracking, and storing information is most important for this. In this paper, the application of Internet of Things (IoT) and Distributed Ledger Technology (Blockchain) are hence discussed by presenting the case of professional Electrical and Electronic Equipment (EEE) in Italy. Within the context of CE, prevention of electronic waste (WEEE) is extremely relevant as it is a fast-growing waste stream, and the products contain environmentally damaging substances as well as valuable and rare materials. The use of a proper combination of IoT and blockchain can help the producers to keep control on products until EEE end-of-life, while promoting CE strategies and supporting decision-making. Based on the outcomes of five interviews conducted in 2019 to companies of the EEE sector, potential improvements in the EEE end-of-use management are discussed. After providing the definition of requirements for both the technical solution and its testing are provided, three solution variations and the related business models are created and presented, as well as considerations on their environmental and economic impacts. The study shows how digital technologies can support the appropriate and circular management of EEE products and WEEE.
The German Energiewende is a deliberate transformation of an established industrial economy towards a nearly CO2-free energy system accompanied by a phase out of nuclear energy. Its governance requires knowledge on how to steer the transition from the existing status quo to the target situation (transformation knowledge). The energy system is, however, a complex socio-technical system whose dynamics are influenced by behavioural and institutional aspects, which are badly represented by the dominant techno-economic scenario studies. In this paper, we therefore investigate and identify characteristics of model studies that make agent-based modelling supportive for the generation of transformation knowledge for the Energiewende. This is done by reflecting on the experiences gained from four different applications of agent-based models. In particular, we analyse whether the studies have improved our understanding of policies' impacts on the energy system, whether the knowledge derived is useful for practitioners, how valid understanding derived by the studies is, and whether the insights can be used beyond the initial case-studies. We conclude that agent-based modelling has a high potential to generate transformation knowledge, but that the design of projects in which the models are developed and used is of major importance to reap this potential. Well-informed and goal-oriented stakeholder involvement and a strong collaboration between data collection and model development are crucial.
A continuing trend of global urbanization leads to a geographical concentration of population and social activities that causes a regional compression of concomitant resource and energy consumption. This paper argues that a Sustainable Living Lab infrastructure (SusLab) in urban areas facilitates a systematic integration of user's consideration in the design and development of Product-Service Systems (PSS) that enables changes of daily routines in favor of urban wealth development and conservation of ecosystem services. The authors build on the Sustainable Consumption and Production (SCP) Model of the Wuppertal Institute that provides a theoretical framework of sociotechnical rearrangements towards urban sustainability transition. Therefore, a reconfiguration of social practices and PSS in a desired direction according to social, ecological and economic concerns is reconsidered on the micro level in line with efficiency, consistency, and sufficiency strategies. The authors introduce an assessment framework for urban sustainable development and illustrate multifarious concepts of PSS that are aiming to decouple wealth development from resource and energy consumption in urban areas.
A key challenge of the 21st century is to transform society into one that features sustainable patterns of production and consumption. To achieve this, transition processes need to be designed in key areas such as housing, mobility and nutrition. The design and large-scale implementation of sustainable product service systems (PSS) is regarded a promising approach for sustainability transitions. Real-life socio-technical experiments are an important infrastructure for designing PSS in collaboration with stakeholders and users. In this paper, we argue that transdisciplinary and action research methods are required for institutionalising an experimental set-up and developing PSS within such infrastructures. We present the Sustainable LivingLabs (SLL) research infrastructure and its methodology as an example of such experimental settings. It was collaboratively developed with key stakeholders in three consecutive research projects and applied to e.g. heating and space heating. We show new qualities of SLL in relation to existing LivingLabs and approaches for PSS design and present its methodological three-phase model (insight research, prototyping, field testing) of research. Our article contributes to knowledge on a methodological framework and tool-kit for PSS development in SLL with a clear focus on socio-ecological sustainability. Intermediate findings confirm the high influence of user practices on heating energy consumption and show starting points for PSS development: e.g. transformational products, home-automation combined with consulting along value chains. We hypothesise that developing PSS in user- and stakeholder-integrated settings supports acceptance and diffusion and, by taking into account users' social practices of utilising novelties, reduces rebound effects caused by incorrect application.
Urban GHG emissions and resource flows : methods for understanding the complex functioning of cities
(2015)
This paper sums up the recent developments in concepts and methods being used to measure the impacts of cities on environmental sustainability. It differentiates between a dominant trend in research literature that concentrates on the accounting and allocation of greenhouse gas (GHG) emissions and energy use to cities, and a re-emergence of studies focusing on the direct and indirect urban material and resource flows. The availability of reliable data and standard protocols is greater in the GHG accounting field and continues to grow rapidly.
The aim of this study is to contribute to a learning process about innovative and successful approaches to overcoming problems and challenges of urban environmental protection. To this end, a detailed overview of the importance of environmental challenges, political priorities and successful solutions in selected countries and cities is given. Based on this, the study analyzes specific success factors and discusses the extent to which these can be transferred and replicated to other cities. Finally, recommendations are made for cities, countries and the international community on how environmental protection at the urban level can be further strengthened. The role of German cities and institutions will also be discussed. The case studies analyzed include Belo Horizonte in Brazil, Moscow in Russia, Kochi in India, Beijing in China, Cape Town in South Africa and Jakarta in Indonesia. These cities were selected because they have already implemented successful policies, measures and other initiatives in the past. For each city, the study analyzes relevant policy documents in order to present the respective challenges and political priorities. The analysis aims to understand the effectiveness of the plans and instruments taking into account the national political environment. Despite the cross-sectoral approach, the analysis of each case study focuses on specific sectors in order to produce well-founded results. The success factors that are worked out based on this sectoral analysis are placed in a holistic context in order to be able to make generalizable statements about success factors.
The waste prevention program (WPP) from 2013 must be evaluated every 6 years and updated if necessary. The review and evaluation of the implementation of the WPP took place within the scope of the project. Based on the analysis results for the implementation of the WPP at federal, state and municipal level and an assessment of existing prevention potentials, concrete proposals for a possible further development and updating of the program on prioritized waste streams and corresponding priority prevention approaches were developed. In addition, structural adjustment and change needs of the WPP were worked out and further research was shown.
Market mechanisms - the Clean Development Mechanism (CDM), Joint Implementation (JI) and Art. 17 emission trading - have been a central feature of the Kyoto Protocol. The Parties to the United Nations Framework Convention on Climate Change (UNFCCC) intend to adopt a new comprehensive climate agreement at this year's Conference of the Parties (COP) in Paris. The shape of the new agreement is emerging only slowly, including the role market mechanisms will play.
To gauge the potential scope of market mechanisms in the forthcoming Paris agreement, this paper surveys the submitted INDCs on the question to what extent they envisage the use of market mechanisms. In detail, the paper looks at five questions for each INDC:
- Does the INDC make any mention of market mechanisms?
- Does the Party plan to use market mechanisms to achieve its contribution to the Paris agreement?
- If a Party intends to use market mechanisms, does the INDC specify which mechanisms or types of units the country intends to use?
- Does the Party quantify the extent to which it intends to use market mechanisms? Under the Kyoto Protocol, use of mechanisms has been supposed to be supplemental to domestic action, though this principle has never been quantified.
- Does the Party specify how the use of mechanisms will ensure environmental integrity and avoid double counting?
At COP 17 Durban, parties decided to establish a centralised new market-based mechanism (NMM) and to consider establishing a "framework for various approaches" to govern decentralised initiatives. Parties have also discussed possible use and up-scaling of non market based approaches (NMA) in this context. This Policy Brief summarises the state-of-play regarding the submissions by parties and observers as of Jan 2015. It is an update on previous JIKO policy papers and therefore focuses on comparable aspects of the discussion.
Energy service companies (ESCOs) play crucial role in building energy efficiency retrofit sector. However limited access to green financing has prevented ESCOs in their expansions in China. This paper, based on a survey of 469 samples and on-site visiting to and interviewing relevant 50 actors of ESCOs, financial institutions and local housing authorities, identifies main barriers of accessing to green financing at both systemic policy level and operational meso and micro level in China, and analyzes good practices at local level that overcome the barriers. The paper concludes that, although there are barriers existing at the policy level in China, substantial attentions and priorities should be given to take actions for overcoming the barriers existed at the operational meso and micro level. The paper suggests that the good practices of capacity building for ESCOs and local financial sector, intensifying participation of intermediate organizations or facilitators and diversifying financial sources and funding mechanisms and models that emerge from the local level should be disseminated in China.
What can reasonably be expected from the UNFCCC process and the climate conference in Paris 2015? To achieve transformative change, prevailing unsustainable routines embedded in socio-economic systems have to be translated into new and sustainable ones. This article conceptualizes the UNFCCC and the associated policy processes as a catalyst for this translation by applying a structurational regime model. This model provides an analytical distinction of rules (norms and shared meaning) and resources (economic resources as well as authoritative and allocative power) and allows us to conceptualize agency on various levels, including beyond nation states. The analysis concludes that the UNFCCC's narrow focus on emission targets, which essentially is a focus on resources, has proven ineffective. In addition, the static division of industrialized and developing countries in the Convention's annexes and the consensus-based decision-making rules have impeded ambitious climate protection. The article concludes that the UNFCCC is much better equipped to provide rules for climate protection activities and should consciously expand this feature to improve its impact.
Accelerating the diffusion of domestic biogas is considered to be a promising option for reaching the goal of universal access to energy by 2030, particularly for the provision of cooking energy for rural populations in developing countries. The aim of this study is to develop a systematic account of the factors that influence the diffusion of domestic biogas technologies. To achieve this objective, a three step analysis approach is applied. In the first step, a conceptual model is built based on insights from scholars that have been studying the diffusion of energy innovations in rural contexts. In the next step, a qualitative content analysis of scientific literature is undertaken to test and refine the categories proposed by the conceptual model and to systematically organise the empirical evidence of the factors that influence the diffusion of domestic biogas in developing and emerging countries. The systemised evidence is used to identify the components and interactions between the household configurations and socio-economic context that determine both the adoption process at household level and the overall technology diffusion. Finally, in the last step, we reflect on the implications of the resultant systematic conceptualisation regarding the purpose and design of programmes promoting the dissemination of domestic biogas technologies.
Questions regarding the societal impact of research, how to reach impact and what is needed to stabilize the effects are rising from various sides. Societal impact is seen as part of a social contract that exists between science and society. This entails that research must address pressing social issues which in turn implies a number of core challenges such as gathering evidence or the creation of actionable knowledge. The transdisciplinary research approach "real-world laboratory" is discussed as possible way to address and to overcome some of the challenges. A "real-world laboratory" currently being established in the city of Wuppertal serves as case study, linking conceptual and empirical investigations.
Sustainability research builds upon its mutual relationship with the society to find futureoriented solutions to deal with societal challenges. In other words, it is a matter of research to produce societal impact. Furthermore, funders and researchers themselves increasingly desire for accountability, to show if societal impact is achieved. To deal with that, two adaptive questions have to be answered: How can societal impact be understood or defined? And what can be learned from theoretical and methodological approaches, as well as practical examples? Built on the answers through a comprehensive literature review and expert interviews, the third question is asked: How can the assessment of societal impact of sustainability-oriented Projects look in practice? The result is the development of a holistic framework on the project-level and its operationalization. It was tested on three cases of the Wuppertal Institute, which has the mission to be a pulse generator for a sustainable societal transformation. The results show that the tool is implementable and a start of an assessment series. Nevertheless, the lack of consensus about the theoretical background influences the design of practical applications. One significant development is the focus shift of the assessment towards the project process and its productive interactions. This enables to collect data about whether societal impact is produced, but also how. The results suggest that clear assessment boundaries are required to deal with uncontrollable externalities. Furthermore, a practical question of the thesis is, if the integration of directly involved stakeholders into the assessment provide an added value. This can be answered positively. But it should be also observed that financial and human resources are key challenges about the extent, as well as the processing of the results. The analysis indicates that to assess societal impact is a suitable instrument and a key step to deal with societal challenges. The developed holistic framework and its operationalization can be used to inspire future research.
Contrary to "static" pathways that are defined once for all, this article deals with the need for policy makers to adopt a dynamic adaptive policy pathway for managing decarbonization over the period of implementation. When choosing a pathway as the most desirable option, it is important to keep in mind that each decarbonization option relies on the implementation of specific policies and instruments. Given structural, effectiveness, and timing uncertainties specific to each policy option, they may fail in delivering the expected outcomes in time. The possibility of diverging from an initial decarbonization trajectory to another one without incurring excessive costs should therefore be a strategic element in the design of an appropriate decarbonization strategy. The article relies on initial experiences in France and Germany on decarbonization planning and implementation to define elements for managing dynamic adjustment issues. Such an adaptive pathway strategy should combine long-lived incentives, like a pre-announced escalating carbon price, to form consistent expectations, as well as adaptive policies to improve overall robustness and resilience. We sketch key elements of a monitoring process based on an ex ante definition of leading indicators that should be assessed regularly and combined with signposts and trigger values at the subsector level.
Two for one : integrating the sustainable development agenda with international climate policy
(2017)
2015 was a watershed for international sustainability governance. With the Paris climate agreement and Agenda 2030, the international community adopted new targets and processes which are to guide policy for decades to come. Both emphasise the need for integration. In practice, however, climate change and sustainable development have so far been siloed issues.
The Glasgow climate conference marked a symbolic juncture, lying half-way between the adoption of the UNFCCC in 1992 and the year 2050 in which according to the IPCC special report on the 1.5°C limit net zero CO2 emissions need to be reached, globally, in order to maintain a good chance of achieving the 1.5°C limit. This article undertakes an assessment of what the UNFCCC and in particular the Paris Agreement and its implementation process have actually achieved so far up to and including the results of the Glasgow conference. The article discusses efforts at ambition raising both within and outside the formal diplomatic process, the finalization of the implementation rules of the Paris Agreement, as well as progress on gender responsiveness, climate finance, adaptation and loss and damage. In summary, the Paris Agreement and its implementation can be considered a success as it is having a discernible impact on the behavior of parties as well as on non-party actors. However, significant further efforts will be required to actually achieve the objectives of the Agreement.
The cost of power is usually calculated by focusing only on the power plant - equipment, operating cost, maintenance and fuel. However, the true cost of generating power goes beyond that, and includes costs that society has to pay for, such as air and water pollution, displacement of communities and the effects of climate change caused by carbon emissions from the power plants. This report by energy researcher Maria Yetano Roche uses well established international methods to identify the true Nigerian cost of each energy source.
Local implementation projects for sector coupling play an important role in the transformation to a more sustainable energy system. Despite various technical possibilities, there are various barriers to the realisation of local projects. Against this backdrop, we introduce an inter- and transdisciplinary approach to identifying and evaluating different power-to-X paths as well as setting up robust local implementation projects, which account for existing drivers and potential hurdles early on. After developing the approach conceptually, we exemplify our elaborations by applying them to a use case in the German city of Wuppertal. It can be shown that a mix of several interlinked interdisciplinary methods as well as several participatory elements is suitable for triggering a collective, local innovation process. However, the timing and extent of end-user integration remain a balancing act. The paper does not focus on a detailed description of power-to-X (PtX) as a central pillar of the sustainable transformation of the energy system. Rather, it focuses on the innovative methodological approach used to select a suitable use path and design a corresponding business model. The research approach was successfully implemented in the specific case study. However, it also becomes clear that the local-specific consideration entails limitations with regard to the transferability of the research design to other spatial contexts.
Decarbonizing transportation in emerging economies will be one of the key challenges in global climate change mitigation efforts. In this paper, pathways are developed towards achieving a 1.5° degree scenario for land-transport for four emerging economies (Brazil, India, Kenya and Vietnam). The aim is to highlight the key opportunities and challenges for low-carbon transport in countries with rapidly growing mobility demand. The main focus of this paper is to reconcile actual and required emission reduction targets and develop plausible pathways to achieve these targets. The paper also identifies potential strategies and measures for these countries to follow these pathways. The analysis considers the contributions of "avoid" (cutting travel growth), "shift" (to lower CO2 modes) and "improve" (vehicle and fuel CO2 characteristics) interventions to decarbonisation scenarios. These scenarios aim to inform renewed Nationally Determined Contributions and shed light on the feasibility of deep decarbonisation pathways that would be in line with the Paris Agreement. Results from this study show that achieving 1.5DS would require dramatic changes in travel patterns, technology and fuels, and major intensification of current policy approaches. Decarbonization solutions will need to include greater use and investment of efficient modes, major shifts toward near-zero carbon fuels such as clean electricity, systems integration, modal shift and urban planning solutions. Although the socio-economic situations and national transport systems differ between the selected countries, some fairly similar strategies appear likely to be core to the mitigation effort, such as rapid growth in light- and heavy-duty vehicle electrification and investments in public transit systems.
The transport sector is the second largest and one of the fastest growing energy end-use sectors, representing 24% of global energy-related greenhouse gas emissions. The International Energy Agency has developed scenarios for the transport sector within the overall concept of mitigation pathways that would be required to limit global warming to 2 °C. This paper builds on these scenarios and illustrates various passenger travel-related strategies for achieving a 2° transport scenario, in particular looking at how much technology improvement is needed in the light of different changes in travel and modal shares in OECD and non-OECD countries. It finds that an integrated approach using all feasible policy options is likely to deliver the required emission reductions at least cost, and that stronger travel-related measures result in significantly lower technological requirements.
Also in the global South, transport already significantly contributes to climate change and has high growth rates. Further rapid motorisation of countries in Asia and Latin America could counteract any climate efforts and aggravate problems of noxious emissions, noise and congestion.
This Paper aims at connecting the need for transport actions in developing countries to the international negotiations on a post-2012 climate change agreement. It outlines the decisions to be taken in Copenhagen and the preparations to adequately implement these decisions from 2013. Arguing, that a sustainable transport approach needs to set up comprehensive policy packages, the paper assesses the substance of current climate negotiations against the fit to sustainable transport. It concludes that the transport sector's importance should be highlighted and a significant contribution to mitigation efforts required.
Combining the two perspectives lead to several concrete suggestions: Existing elements of the carbon market should be improved (e.g. discounting), but an upscale of the carbon market would not be an appropriate solution. Due to a lack of additionality, offsetting industrialised countries' targets would finally undermine the overall success of the climate agreement. Instead, a mitigation fund should be established under the UNFCCC and financed by industrialised countries. This fund should explicitly enable developing countries to implement national sustainable development transport and mobility policies as well as local projects. While industrialized countries would set up target achievement plans, developing countries should outline low carbon development strategies, including a section on transport policy.
A cost-minimizing electricity market model was used to explore optimized infrastructures for the integration of renewable energies in interconnected North African power systems until 2030. The results show that the five countries Morocco, Algeria, Tunisia, Libya and Egypt could together achieve significant economic benefits, reaching up to EUR 3.4 billion, if they increase power system integration, build interconnectors and cooperate on joint utilization of their generation assets. Net electricity exports out of North Africa to Europe or Eastern Mediterranean regions, however, were not observed in the regime of integrated electricity markets until 2030, and could only be realized by much higher levels of renewable energy penetration than currently foreseen by North African governments.
With the introduction of the Roadmap to a Resource Efficient Europe (2011) and the more recent commitment of The Action Plan towards the Circular Economy (2015), the European Commission (EC) has expressed its fundamental interest to substantially improve the resource efficiency of the European economy and enable the transition towards the Circular Economy (CE). This policy push has meanwhile been complemented by some quite ambitious national programmes for RE and CE and institutional advances but it is not yet bound to targets or mandatory reporting.
Against this background, the objective of this paper is to give a comprehensive overview of the current policy frameworks at EU and a selection of MSs and provide insights into the elements shaping policy processes. The analytical framework relies on three essential interconnected components: the policy framework, the economic incentive system and economic side policies which are relevant in the context of RE and CE and actor constellations. The paper does this looking at the interface between EU-MSs. The analysis is based on different empirical surveys in which the policy development is observed and discussed (EEA 2011, 2016a, 2016b, EIO 2013, 2014, 2016) and a comprehensive review of legislative and policy frameworks at the EU and selected MSs, undertaken as part of the project POLFREE (Policy option for a Resource-Efficient Economy) (Domenech et al., 2014, Bahn-Walkowiak et al., 2014). The analysis reveals that policy frameworks for RE/CE are complex and fragmented as competing goals and visions reduce effectiveness of measures. The paper makes recommendations as to how EU and MS policies could improve RE in a coordinated way, but recognizes that achieving such coordination will be challenging in the current political context.
Sustainability policy in the early 2000s is based on and therefore influenced by scientific literature on "transition". The importance of this link has inspired the authors to explore the structure of cooperating authors and citation networks in the field. In order to understand "transition" literature, we compare it with an alternative term for change, "transformation", which is also used in the context of socio-technical shifts towards sustainability. We expose the different structures of these fields with an overview of keywords, key references, key authors, and the coherence between references and authors. By analysing co-author and citation networks, we find large differences in these groups of documents. The transition literature is characterised by a large network of directly and indirectly cooperating authors with clear clusters; transformation literature contains smaller author networks. Key transition authors are predominantly Dutch. They repeatedly write together and cite each other's work. The transition literature is tightly knit with high degrees of internal references and a clearly distinguishable core. Transformation literature has fewer connections between authors and articles. The connecting articles, each with many global citations, form its basis. This analysis can be used as a step to continue the debate on the role of transition and transformation literature in sustainability and renewable energy policy. The transformation literature teaches us that older streams of thought are still relevant and may be used as "glue" for linking change with respect to sustainable energy to wider developments. Rediscovering existing literature in new combinations may lead to promising new views on sustainable energy.
Against the background of environmental problems arising from the growing extraction of natural resources and resource depletion, achieving a sustainable development is an indispensable challenge in the twenty-first century. In this article we want to show how socio-technical and product-service innovations can change social practices - the routine doings in everyday life - and, thus, support transition of socio-technical systems. We introduce theoretical considerations on how social practice theories and the framework of the Multi-Level Perspective in transition research can be linked to better understand transition processes from a micro-macro-link perspective. We then present cases based on desk research in the field of practices in bathing, heating and nutrition to show how these have changed over the past decades. Building on this, examples of concepts for sustainable product-service-design in these areas are introduced as leverage points to change social practices in everyday life. These have been developed in research projects or design student seminar works, respectively. We argue that this implies sustainable product-service-systems should be developed in a user- and actor-integrated framework, such as Sustainable LivingLabs. The integration of users and other stakeholders into participatory co-creation processes enables tailored solutions that take actual routines and dependencies seriously into account.
There is general agreement that preventing dangerous climate change requires a fundamental transformation of the global economy. Regarding carbon markets, the EU, for example, has called for the new market-based mechanism (NMM) to be established under the UNFCCC to "facilitate transition towards low carbon economy and attract further international investment". This JIKO Policy Paper discusses the transformative potential of the NMM and how it should be structured to maximize transformative impact.
The analysis shows that details in the arrangements of the scheme, such as allocation of allowances can significantly influence the incentive structure of the instrument and hence its potential to contribute to transformational change. The authors conclude that carbon pricing is necessary but is by itself not sufficient to redeem the various types of market failures that have led to the unsustainable global socio-economic system we are deemed to change. An NMM should therefore be tailored to complement other national policies.
Science and education are central fields and a lever for sustainable development. With the newly developed student teaching and learning format "Transformative Innovation Lab" - TIL for short - students are to be enabled to conduct independent transformative research. To this end, the researchers, under the direction of the Wuppertal Institute, developed and tested the new learning concept in the project "Development, testing and dissemination of new qualification offers for 'change agents' for transformative learning using the real-world laboratory approach" (EEVA). The detailed results and numerous implementation tips have been published in a practical handbook aimed at academic teaching staff and other multipliers.
Social innovations, which transform resource intensive routines and practices into low-resource ones, combined with socio-technically designed transition paths, which are created around sustainability and environmental criteria, are milestones for implementation and diffusion of SCP (Sustainable Consumption and Production). This paper analyses such processes based on eight key components in order to evaluate and explain transformation and transition towards a sustainable lifestyle. Actors on all levels of society are included in this approach, creating a whole framework. Global megatrends, such as climate change, demographic change or resource scarcity will be put into relation with current policies and production trends, which play an important role for the development of transition pathways and future scenarios. This will enable us to work out guidelines and ideas on how to create a more sustainable society specifically.
The energy system of Jordan is facing a rise in energy demand while at the same time having quite limited own conventional energy resources. Especially because of their high import dependency, Jordan is starting to change its energy system and puts a higher focus on renewable energy (like wind and solar) and energy efficiency.
In this short paper the authors discuss the transformation of energy companies in Germany and highlight the possibilities of energy efficiency services. Furthermore, they examinate the transferability to Jordan, based on the results of a questionnaire among Jordan energy experts. Due to the low level of research knowledge in the specific field, this is an exploratory research approach. The role, challenges and opportunities of Jordan's state-owned National Electric Power Company NEPCO have been highlighted.
The transdisciplinary research mode has gained prominence in the research on and for sustainability transformations. Yet, solution-oriented research addressing complex sustainability problems has become complex itself, with new transdisciplinary research formats being developed and tested for this purpose. Application of new formats offers learning potentials from experience. To this end, we accompanied fourteen research projects conceptualized as real-world labs (RwLs) from 2015 to 2018. RwLs were part of a funding program on "Science for Sustainability" in the German federal state of Baden-Württemberg. Here, we combine conceptual and empirical work to a structured collection of experiences and provide a comprehensive account of RwLs. First, we outline characteristics of RwLs as transformation oriented, transdisciplinary research approach, using experiments, enabling learning and having a long-term orientation. Second, we outline eleven success factors and concrete design notes we gained through a survey of the 14 RwLs: (1) find the right balance between scientific and societal aims, (2) address the practitioners needs and restrictions, (3) make use of the experimentation concept, (4) actively communicate, (5) develop a "collaboration culture", (6) be attached to concrete sites, (7) create lasting impact and transferability, (8) plan for sufficient time and financial means, (9) adaptability, (10) research-based learning, and (11) recognize dependency on external actors. Characteristics and success factors are combined to illustrate practical challenges in RwLs. Third, we show which methods could be used to cope with challenges in RwLs. We conclude discussing the state of debate on RwLs and outline future avenues of research.
Community-based approaches to natural resource management are being discussed and experienced as promising ways for pursuing ecological conservation and socio-economic development simultaneously. However, the multiplicity of levels, scales, objectives and actors that are involved in sustainability transformations tends to be challenging for such bottom-up approaches. Collaborative and polycentric governance schemes are proposed for dealing with those challenges. What has not been fully explored is how knowledge from local contexts of community-based initiatives can be diffused to influence practices on higher levels and/or in other local contexts. This study explores how theoretical advances in the diffusion of grassroots innovation can contribute to understanding and supporting the diffusion of knowledge and practices from community-based initiatives and proposes a transdisciplinary approach to diffusion. For that aim, we develop an analytical perspective on the diffusion of grassroots innovations that takes into consideration the multiplicity of actors, levels and scales, the different qualities/types of knowledge and practices, as well as their respective contributions. We focus on the multiplicity and situatedness of cognitive frames and conceptualize the diffusion of grassroots innovations as a transdisciplinary process. In this way three different diffusion pathways are derived in which the knowledge and practices of grassroots initiatives can be processed in order to promote their (re)interpretation and (re)application in situations and by actors that do not share the cognitive frame and the local context of the originating grassroots initiative. The application of the developed approach is illustrated through transdisciplinary research for the diffusion of sustainable family farming innovations in Colombia. This conceptualization accounts for the emergence of multiplicity as an outcome of diffusion by emphasizing difference as a core resource in building sustainable futures.
Decarbonisation of energy systems requires deep structural change. The purpose of this research was to analyse the rates of change taking place in the energy systems of the European Union (EU), in the light of the EU's climate change mitigation objectives. Trends on indicators such as energy intensity and carbon intensity of energy were compared with decadal benchmarks derived from deep decarbonisation scenarios for the electricity, residential, transport, and industry sectors. The methodology applied provides a useful and informative approach to tracking decarbonisation of energy systems. The results show that the EU has made significant progress in decarbonising its energy systems. On a number of indicators assessed the results show that a significant acceleration from historical levels is required in order to reach the rates of change seen on the future benchmarks for deep decarbonisation. The methodology applied provides an example of how the research community and international organisations could complement the transparency mechanism developed by the Paris Agreement on climate change, to improve understanding of progress toward low-carbon energy systems.
The transition towards a circular economy is high on the political agenda and support for innovative business models can be seen as one of the key strategies for its implementation. Nevertheless most of these business models rely on an increasing generation of waste and thus undermine the prevention of waste as top of the waste hierarchy. The paper aims to link this debate to more systemic eco-innovations that offer economic market potentials by reduced material inputs and waste generation. This directs the attention to sufficiency strategies that surpass the level of individual consumer choices and regards the potentials of entrepreneurial sufficiency strategies. It takes the example of waste contracting modelsin Germany as a possible approach of resource-light business models that provide existing utility aspects with altered consumption patterns and decreased resource consumption. It describes environmental and economic benefits and draws conclusions on necessary policy framework conditions.
A policy framework for sustainable resource management (SRM) is required both to guarantee the materials and energy supply of the EU economy and safeguard the natural resource basis in the future. Goals and strategies for sustaining the metabolism of the economy are described. Data are presented on the material throughput and physical growth of the EU's economy, on total material requirements (TMR), its composition, the decoupling from economic growth, and the increased shift to other regions. A first future target Material Flow Balance (t- MFB) of the EU is outlined. Detailed data reveal the "top ten" resource flows. Policy design for SRM should aim at an integrated and balanced approach along the material flow, comprising resource extraction, the product cycle and final waste disposal. Strategies and potential instruments to manage fossil fuels, metals and industrial minerals, construction minerals and excavation are discussed. Possible priorities and examples are given for target setting, focusing on limited expansion of built-up area, reduced use of non-renewables, increased resource productivity, and shift to sustainable cultivation of biomass.
This study focuses on the economic, market-related context of consumption patterns and incorporates the regulatory settings and values. The aim is to systemise the influences on sustainable consumption patterns. Special attention is drawn to the question how existing niche markets could be extended to mass markets. This question is deepened by case studies on the green textile and the green power markets. The results emphasise the different key factors which influence the successful pathways for an extended green market volume. Looking at the case of the green power market it can be seen how important it is to create an economic and institutional context for adoption. Looking at the case of green textiles the importance of new lifestyles and cultural impacts are obvious. Looking at the interfaces between institutional settings, supply structure, societal values and consumers' decision-making, it can be seen that consumers' demands are not only a product of individual needs. Therefore sustainable consumption strategies will have to face not only the change of needs, but also the change of structures which influence individual choices.
Economic performance of a country is generally being measured through GDP (Gross Domestic Product), a variable that has also become the de facto universal metric for "standards of living". However, GDP does not properly account for social and environmental costs and benefits. It is also difficult to achieve sustainable decision-making aiming at sustainable progress and well-being if welfare is being considered from a purely financial point of view. The study highlights the benefits and some of the shortcomings of GDP. It serves as a helpful and practicable instrument for monetary and fiscal policies. The real problem presumably is that GDP growth is too often confused with (sustainable) welfare growth in people's minds. While there certainly is a correlation between the two, this study shows that this is a highly conditional correlation, void of substantial causality for GDP levels observable in the European Union. In order to be able to assess people's well-being and general sustainable development in the sense of sustainability, an alternative instrument going beyond GDP is necessary. Using so called SWOT analyses, several alternative progress indicators have been assessed in the context of this study. On the one hand it was analysed how far ecological and social factors can be integrated in the GDP measurements. Thereby difficulties arose then trying to monetise these factors. As a further possibility indicators were analysed which are to replace GDP as a whole. The category supplementing GDP seems to be the most realistic and acceptable option for going beyond GDP. Within this approach, GDP is being complemented with additional environmental and/or social information. In order to make this kind of solution feasible the study claims the establishment of an overarching and transparent indicator system for improving economic decision-making in support of sustainable development.
This paper discusses options to increase mitigation ambition in crediting mechanisms that serve the Paris Agreement (PA), such as the Article 6.4 mechanism. Under the Clean Development Mechanism and other crediting mechanisms, baselines have been specified in the form of greenhouse gas (GHG) intensity factors and linked to business-as-usual developments. This means that with increasing production of goods and services through carbon market activities, absolute emissions may increase or fall only slowly. At a global level, such an approach widens the "emissions gap". To enable continued use of emissions intensity baselines in crediting mechanisms while being in line with the PA’s goal to pursue efforts to limit temperature rise to 1.5˚C, we propose to apply an "ambition coefficient" to emissions intensities of technologies when establishing the baseline. This coefficient would decrease to reflect increasing ambition over time, and reach zero when a country needs to reach net zero emissions. Due to the principle of common but differentiated responsibilities and respective capabilities, the coefficient would fall more quickly for developed than for developing countries. The latter would be able to generate emission reduction credits well beyond 2050, while for the former, crediting would stop around 2035 or before. An ambition coefficient approach would generate certainty for carbon market investors and preserve trust in international carbon markets that operate in line with the agreed, long-term ambition of the international climate regime.
The word "literacy" has come to be used to describe a wide range of competencies, including design literacy - a term that, despite its presence in design discourse, is still characterised by a certain fuzziness. In this paper, we explore this highly discursive theoretical field in order to gain a more nuanced and expanded understanding of the topic. In doing so, we argue that these divergent positions are also due to the ambiguity of the term “design”.
We understand design as the perpetual de- and reconstruction of the world, as a way of worldmaking, both physically and conceptually. Thus, design literacy can be understood as a way to perceive traces of design and its processes, to perceive the world as contingent: a circular cognitive process of recognising that something - if not everything - in our cultural pluriverse is designed, understanding how it was designed and that it can potentially become the subject of design again and again. In our paper, we emphasise the contingency of design - and the ethical level that can arise from understanding the possibility of a different design.
Ultimately, our aim with this paper is to emphasise that design literacy is a crucial competence for encouraging pluralistic perspectives and initiating transition processes, as it helps to acknowledge the temporary necessity but long-term non-necessity of things (which particularly includes the transitory nature of one's own creations).
Towards an effective and equitable climate change agreement : a Wuppertal proposal for Copenhagen
(2009)
This paper presents comprehensive proposals for the post-2012 climate regime: the scale of the challenge, emission targets for industrialised countries, increased actions by Southern countries, financing, technology, adaptation and deforestation. The proposals are based on ongoing research by the Wuppertal Institute.
The paper reviews the current knowledge on the use of biomass for non-food purposes, critically discusses its environmental sustainability implications, and describes the needs for further research, thus enabling a more balanced policy approach. The life-cylce wide impacts of the use of biomass for energy and material purposes derived from either direct crop harvest or residuals indicate that biomass based substitutes have a different, not always superior environmental performance than comparable fossil based products. Cascading use, i.e. when biomass is used for material products first and the energy content is recovered from the end-of-life products, tends to provide a higher environmental benefit than primary use as fuel. Due to limited global land resources, non-food biomass may only substitute for a certain share of non-renewables. If the demand for non-food biomass, especially fuel crops and its derivates, continues to grow this will inevitably lead to an expansion of global arable land at the expense of natural ecosystems such as savannas and tropical rain forests. Whereas the current aspirations and incentives to increase the use of non-food biomass are intended to counteract climate change and environmental degradation, they are thus bound to a high risk of problem shifting and may even lead to a global deterioration of the environment. Although the "balanced approach" of the European Union's biomass strategy may be deemed a good principle, the concrete targets and implementation measures in the Union and countries like Germany should be revisited. Likewise, countries like Brazil and Indonesia may revisit their strategies to use their natural resources for export or domestic purposes. Further research is needed to optimize the use of biomass within and between regions.
The study "Towards a Single and Innovative European Transport System" is developing action plans for the establishment of an integrated transport system in Europe. This report was created in a joint effort between VDI/VDE Innovation + Technik GmbH (Germany), Wuppertal Institute for Climate, Environment and Energy (Germany) and the Centre of Research and Technology Hellas, CERTH (Greece) on behalf of the European Commission's DG MOVE. Focus of the report is the international assessment of six different countries - Brazil, China, India, Japan, South Korea, USA - in five focus areas across all transportation modes. It provides actions plans on how to overcome existing European barriers towards a single and innovative European Transport System based on best practices and lessons learned in the countries under study. In addition to the actions plans, the study also provides recommendations for international collaboration.
Towards a resource policy : unleashing productivity dynamics and balancing international distortions
(2012)
The paper outlines guidelines and pillars of a resource policy. Two reasons favour the formulation of such policy: a demand to increase sluggish resource productivity growth as well as environmental damages occurring along material flows at an international scale. Thus, it is both the innovation and environmental perspective that legitimate policies. The paper surveys recent empirical trends. Referring to research on innovation and transition management, it develops guidelines for a resource policy, namely, market order, provision function, learning processes, market development, and orientation. It furthermore describes four instruments as potential pillars of a future policy mix: a tax on construction minerals, an ecologically differentiated VAT tax, and an international covenant for metals and an international convention for sustainable resource management. The paper finally reflects these guidelines and pillars against weaknesses and ongoing discussions of climate policy. It concludes that despite all uncertainties and complexities, a well-designed resource policy is on the verge of becoming essential for unleashing eco-innovation dynamics.
22 years are left until the German target for climate neutrality should be reached. For the industrial sector, this implies a fundamental change and an acceleration of emission reduction, as from 2000 to 2021 the sector has reduced its greenhouse gas (GHG) emissions by only 13% (ERK, 2022). For the large structures, plants and assets that are characteristic for the energy intensive industrial sectors, the timespan implies no room for delay. One sector facing particular challenges is the chemical industry. Here, fossil resources are used not only for energetic purposes but for feedstock as well, in the petrochemical industry in particular. The efforts made in the petrochemical sector thereby not only affects the sectors own emissions, but the chemicals value chain at large, including the management of end-of-life products. The dependency on energetic resources for material use also means that there is a particular connection from the chemical industry to the energy system at large, which also entails special consideration.
The chemical industry also has a particular relevance to the Antwerp-Rotterdam-Rhine-Ruhr-Area (ARRRA) which hosts several large petrochemical clusters in Germany as well as the Netherlands and Belgium, with complexly interlinked production chains. In reaching the climate targets, these regions especially face significant changes and may have the opportunity to position themselves as frontrunners for industrial transformation. That is, if a successful strategy can be found.
In the recent years, numerous scenario analyses and roadmaps have been released drawing out pathways for chemical industries to develop in line with national and international climate targets. This can entail mapping of technological options, important prerequisites, particular challenges as well as important opportunities and timeframes. This meta-analysis summarizes and compares the findings of some of the most recent previous works at the national, European and global level. As the goal is to investigate the various strategic options and development paths for Germany and the ARRRA, it has a particular focus on roadmaps for Germany, the Netherlands and Belgium. It takes a quantitative as well as qualitative approach, looking both at resource and production volumes, different emission reduction strategies relative importance, as well as policy recommendations and other important framework conditions. A particular focus is put on the use of non-fossil feedstocks to reduce emissions.
In the past few decades, geochemically scarce metals have
become increasingly relevant for emerging technologies in
domains such as energy supply and storage, information and
communication, lighting or transportation, which are regarded as
cornerstones in the transition towards a sustainable post-fossil
society. Accordingly, the supply risks of scarce metals and possible
interventions towards their more sustainable use have been
subject to an intense debate in recent studies. In this article, we
integrate proposed intervention options into a generic life cycle
framework, taking into account issues related to knowledge
provision and to the institutional setting. As a result, we obtain
a landscape of intervention fields that will have to be further
specified to more specific intervention profiles for scarce metals
or metals families. The envisioned profiles are expected to have
the potential to reduce action contingency and to contribute to
meeting the sustainability claims often associated with emerging
technol ogies.
In order to calculate the financial return of energy efficiency measures, a cost-benefit analysis (CBA) is a proven tool for investors. Generally, however, most CBAs for investors have a narrow focus, which is - simply speaking - on investment costs compared with energy cost savings over the life span of the investment. This only provides part of the full picture. Ideally, a comprehensive or extended CBA would take additional benefits as well as additional costs into account. The objective of this paper is to reflect upon integrating into a CBA two important cost components: transaction costs and energy efficiency services - and how they interact. Even though this concept has not been carried out to the knowledge of the authors, we even go a step further to try to apply this idea. In so doing, we carried out a meta-analysis on relevant literature and existing data and interviewed a limited number of energy experts with comprehensive experience in carrying out energy services. Even though data is hardly available, we succeeded in constructing three real-world cases and applied an extended CBA making use of information gathered on transaction costs and energy services costs. We were able to show that, despite these additional cost components, the energy efficiency measures are economically viable. Quantitative data was not available on how energy services reduce transaction costs; more information on this aspect could render our results even more positive. Even though empirical and conceptual research must intensify efforts to design an even more comprehensive CBA, these first-of-its-kind findings can counterargue those that believe energy efficiency is not worth it (in monetary terms) due to transaction costs or energy services costs. In fact, this is good news for energy efficiency and for those that seek to make use of our findings to argue in favor of taking up energy efficiency investments in businesses.
In his essay, the author presents a stock-taking of the debate on Green Deals. The starting point of this personal assessment is a brief outline of the content and impact of a study in which the author and colleagues published a first outline of a "Green New Deal for Europe" as a political response to the 2008 financial crisis. 2008 had been a critical juncture for mainstream economics: however, from the perspective of policy-learning, the period after has been a lost decade. The European Green Deal as presented by the European Commission in 2019 can be perceived as a historic milestone and confirmation of a regime change in mainstream economic policy in which ecological considerations gain in importance. Yet, the Deal suffers from major deficits. In sum, the European Green Deal could be interpreted as an insufficient attempt to take advantage of the rapidly closing windows of opportunity for a peaceful transition towards sustainability. On the eve of a planetary crisis, the governance of economic transitions towards sustainability needs to be improved and accelerated. Reflecting on the 2009 study A Green New Deal for Europe, this essay attempts to draw a few lessons and frugal heuristics for the policy-design of Green Deals.
The Digital Product Passport (DPP) is a concept of a policy instrument particularly pushed by policy circles to contribute to a circular economy. The preliminary design of the DPP is supposed to have product-related information compiled mainly by manufactures and, thus, to provide the basis for more circular products. Given the lack of scientific debate on the DPP, this study seeks to work out design options of the DPP and how these options might benefit stakeholders in a product's value chain. In so doing, we introduce the concept of the DPP and, then, describe the existing regime of regulated and voluntary product information tools focusing on the role of stakeholders. These initial results are reflected in an actor-centered analysis on potential advantages gained through the DPP. Data is generated through desk research and a stakeholder workshop. In particular, by having explored the role the DPP for different actors, we find substantial demand for further research on a variety of issues, for instance, on how to reduce red tape and increase incentives for manufacturers to deliver certain information and on how or through what data collection tool (e.g., database) relevant data can be compiled and how such data is provided to which stakeholder group. We call upon other researchers to close the research gaps explored in this paper also to provide better policy direction on the DPP.
The transformative research approach of Real-World Laboratories (RWL) has recently attracted attention in German sustainability science. Some definitions and understandings have been published, but guidelines and procedural quality criteria for establishing and running a RWL are still missing. To address this gap, this article has two aims. First, it aims to derive key components of RWLs from the current discourse on RWLs and similar, but more elaborated research approaches. Second, it aims to transfer these key components into a comprehensive research practice. This practice is illustrated by the RWL process in the project "Well-being Transformation Wuppertal" (WTW).
Methodologically, the article builds on a review of RWL-related approaches for collaborative, intervention-oriented research. This includes transition management, transdisciplinary process models and action research. Based on this review, eight key components for RWLs are proposed. They position RWLs as a normatively framed approach that aims to contribute to local action for sustainable development and the empowerment of change agents. The approach uses transdisciplinary methods of knowledge integration and engages in cyclical real-world interventions within certain spatial and content-related boundaries.
The components are transferred into a flowchart, detailing process steps, aims, responsibilities and overall principles for putting RWLs into practice. Thus, a hitherto missing tool for designing and running RWLs is provided. Then, the RWL in the district of Mirke, Wuppertal, is used as an empirical example to illustrate the application of the flowchart and related key components. Consecutive discussions centre on the different roles of researchers and practitioners in the research process, as well as the relevance of an underlying theory of change for effective interventions. Finally, critical reflection, application and amendment of the proposed flowchart are encouraged
This report examines the role of waste management in the context of a circular economy transition. Key challenges relate to moving beyond the perception of "waste as a problem" to "waste as a resource". To this end high levels of cooperation are needed between the waste industry and enterprises engaged in circular economy business models. Collecting high quality waste streams for re-use, remanufacturing and recycling also requires citizen engagement and integrated infrastructure development from the municipal to the EU level. Ultimately, both waste prevention as well as a widespread growth in circular economy activities will require a coherent and holistic approach that takes recovery options into account at every stage of the product life cycle. Co-benefits will include reducing environmental burden as well as creating both high-skilled and low-skilled jobs for an inclusive, green economy. In concrete terms, this report examines five waste streams identified in the EU's Circular Economy Action Plan: municipal waste, packaging waste, food waste, bio-waste and critical raw materials. It looks at the current state of policy development, presents trends and data comparing Member State performance, reviews the state of technological development, and assesses employment opportunities relevant to each waste stream in the overarching context of assessing progress toward the circular economy transition in the EU. Case studies of specific options for collecting and treating waste based on experiences in Denmark, Italy and Slovenia complement the more macro-level analysis of trends. Finally, key policy options are identified, in particular focused on ways to prevent waste, align circular economy and waste management objectives and improve the quality and reliability of indicators toward more robust monitoring.
This article presents the accounts of China's Total Material Requirement (TMR) during 1995–2008, which were compiled under the guidelines of Eurostat (2009) and with the Hidden Flow (HF) coefficients developed by the Wuppertal Institute. Subsequently, comparisons with previous studies are conducted. Using decomposition, we finally examine the influential factors that have changed the TMR of China. The main findings are the following: (1) During 1995–2008 China's TMR increased from 32.7 Gt to 57.0 Gt. Domestic extraction dominated China’s TMR, but a continuous decrease of its shares can be observed. In terms of material types, excavation constituted the biggest component of China's TMR, and a shift from biomass to metallic minerals is apparent; (2) Compared with two previous studies on China's TMR, the amounts of TMR in this study are similar to the others, whereas the amounts of the used part of TMR (Direct Material Input, DMI) are quite different as a result of following different guidelines; (3) Compared with developed countries, China's TMR per capita was much lower, but a continuous increase of this indicator can be observed; (4) Factors of Affluence (A) and Material Intensity (T), respectively, contributed the most to the increase and decrease of TMR, but the overall decrease effect is limited.
In this paper, we aim to present a comprehensive analysis on the emerging phenomenon of distributed innovation in commons-based peer production (CBPP) platforms. Starting with the exploration of the widely held belief on value-creation confined to industrial settings, we raise several questions regarding the feasibility of, and a need for, an inclusive innovation process that can tap grassroots capacity into both traditional (industrial research and development) and emerging (peer-to-peer) innovation models to yield sustainable solutions. In particular, we explore the emergence and structuration of digital innovations in the maker movement, as it presents an alternative construct of innovation wherein access to and sharing of knowledge is predominantly distributed. With innovation outcomes often freely revealed, its very structuration could pose a principal challenge to our conceptualizations of value creation and competitive advantage in the current economic model. Drawing from responses received from 200 collaborative innovation platforms, six semi‐structured interviews focusing on socio-technical innovation cases, as well as four in-depth narrative interviews with maker turned entrepreneurs, we present a detailed analysis on the topology of network, typology of actors, as well as the underlying innovation ecosystem in CBPP networks in Germany. In doing so, we contribute to the conceptualization of peer-to-peer distributed innovations in collaborative platforms.
The Durban Climate Conference agreed on the creation of a new market-based mechanism under the United Nations Framework Convention on Climate Change (UNFCCC) and to consider the establishment of an overall framework for various mitigation approaches, including opportunities for using markets ("Framework"). The creation of such a Framework is therefore of high political significance, as it should ensure on the one hand that new market-based mechanisms contribute to global climate change mitigation and to achievement of targets, and on the other hand, that different market-based approaches can be integrated in a global carbon market. As yet, there is little clarity as to the roles and design of such a framework. This paper contributes to the debate by discussing and evaluating inter alia several design options, and explores how the various options could be implemented and how they interrelate. It concludes that a strong central oversight at the level of the UNFCCC is probably the only option that could reassure the vast majority of UNFCCC Parties that the environmental integrity of new market-based mechanisms is in fact ensured. This does, however, not exclude that some reasonable balance may be struck between centralization and flexibility.
Non-residential buildings in the European Union consume more than one third of the building sector's total. Many non-residential buildings are owned by municipalities. This paper reports about an energy saving competition that was carried out in 91 municipal buildings in eight EU member states in 2019. For each public building an energy team was formed. The energy teams' activities encompassed motivating changes in the energy use behaviour of employees and small investments. Two challenges added an element of gamification to the energy saving competition. To assess the success of the energy saving competition, an energy performance baseline was calculated using energy consumption data of each public building from previous years. Energy consumption in the competition year was monitored on a monthly base. After the competition the top energy savers from each country were determined by the percentage-based reduction of energy consumption compared to the baseline. On average, the buildings had an electricity and heat consumption in 2019 that was about 8 % and 7 %, respectively, lower than the baseline. As an additional data source for the evaluation, a survey among energy team members was conducted at the beginning and after the energy competition. Support from superiors, employee interest and motivation and behaviour change as assessed by energy team members show a positive, if weak or moderate, correlation with changes in electricity consumption, but not with changes in heat consumption.
Toothless tiger? : Is the EU action plan on energy efficiency sufficient to reach its target?
(2007)
Motivated by, inter alia, the increasing energy prices, the security of energy supply and climate change, the new EU "Action Plan for Energy Efficiency: Realising the Potential" (EEAP), sets out the policies and measures required to be implemented over the next six years to achieve the EU's goal of reducing annual primary energy consumption by about 20 % by 2020. By increasing energy efficiency, the security of energy supply and the reduction of carbon emissions are also improved.
The paper will analyse the 20 % target of the new EEAP for the energy demand side by comparison with different recent energy scenarios for the EU. It will therefore review the recommended policies and measures and examine, in which energy demand sectors energy efficiency may be increased and to which extend. The main focus is whether the recommended policies and actions will be sufficient and which additional measures may be useful, if additional measures are needed.
To identify the main drivers of transformation, it is helpful to identify the transformation perspectives of three specific schools of thought: idealist, institutional, and technological innovation. By differentiating among these schools of thought, a more informed transformation debate becomes possible, thereby increasing transformative literacy in academia and society.
After a wave of privatizations in the end of the 1990s, the electrical power supply of many municipalities in Germany has been returned into public hands. Many municipalities discover chances and possibilities for local action, which arise with remunicipalisation. The local policy-makers realize that remunicipalisation offers the opportunity of implementing an independent energy policy at local level which is critical in creating a transformation to a sustainable energy system based on energy efficiency and renewable energies. The municipal ownership allows a strong governance towards more political influence in the local energy market. In addition, there is a clear opinion of the population: 81 % of citizens surveyed say they trust their local municipal utility, compared to only 26 % who say they trust corporations (VKU-Survey, 2010). In summary, there are many good reasons for local politicians to establish their own municipal utilities. The payback for municipalities is tangible when the local utility focuses on reliably providing affordable energy rather than on increasing its returns. The new municipal power utilities stimulate competition and contribute to the renewal / restructuring of the traditional energy market.
The founding of 72 municipal utilities since 2005 leads us to ask for the reasons. The study reviews the German trend towards municipal ownership of local utilities, assessing their performance based on 10 targets related to the energy transition, climate protection, and the local economic impact: 1. Achieving environmental objectives and organization of the local "Energiewende". 2. Higher local added value. 3. Harnessing tax regulations for improving municipal services. 4. Improving the income situation of the city. 5. Democratization of supply and stronger orientation towards the common good (public value). 6. Creating and protecting good jobs. 7. Acting in social responsibility in energy supply. 8. Expansion of eco-efficient energy services. 9. Harnessing customer relations and public image. 10. Materialising synergies with other sectors.
Based on expert opinions, the study finds out that the likelihood of these targets being reached is "high to very high". The aim of this article is to provide a compact and basic understanding of the possible reasons for the phenomenon of remunicipalisation.
This study intends to provide a comprehensive overview of the water-energy nexus' relevance to the Iranian electricity sector, by illustrating key trends, analysing water-related challenges and identifying knowledge gaps. It summarises the results of a workshop, and a series of dialogues with Iranian energy and water experts, in which both the current situation and future water-related risks and impacts on the Iranian power sector were discussed. Based on those results, it highlights research needs and further options for scientific collaboration.
This report explores the future role of the voluntary carbon market and its potential to contribute to raising the ambition of climate policy. For this purpose, desk research was complemented by interviews with voluntary carbon market representatives. The report finds that the current roles of the voluntary market are set to change fundamentally due to the Paris Agreement. For the future of the voluntary market as an investor, three roles were identified, each of which is associated with specific challenges: The market may maintain its current role of buyer of carbon neutrality credits, it may become a supporter of NDC implementation, or it may become a driver of ambition. With regard to the future role of private certification standards, the Paris Agreement may hold the possibility of using such standards in the context of compliance activities. Overall, the findings indicate that the voluntary market has some potential to contribute to ambition raising. Whether this potential will actually be unlocked depends on how the concept of ambition raising will be operationalized under the Paris Agreement and to what degree it can be integrated into the voluntary market's activities and business models.
This paper examines the effects of an increased integration of concentrated solar power (CSP) into the conventional electricity systems of Morocco and Algeria. A cost-minimizing linear optimization tool was used to calculate the best CSP plant configuration for Morocco's coal-dominated power system as well as for Algeria, where flexible gas-fired power plants prevail. The results demonstrate that in both North African countries, storage-based CSP plants offer significant economic advantages over non-storage, low-dispatchable CSP configurations. However, in a generalized renewable integration scenario, where CSP has to compete with other renewable generation technologies, like wind or photovoltaic (PV) power, it was found that the cost advantages of dispatchability only justify CSP investments when a relatively high renewable penetration is targeted in the electricity mix.
Energy-intensive processing industries (EPIs) produce iron and steel, aluminum, chemicals, cement, glass, and paper and pulp and are responsible for a large share of global greenhouse gas emissions. To meet 2050 emission targets, an accelerated transition towards deep decarbonization is required in these industries. Insights from sociotechnical and innovation systems perspectives are needed to better understand how to steer and facilitate this transition process. The transitions literature has so far, however, not featured EPIs. This paper positions EPIs within the transitions literature by characterizing their sociotechnical and innovation systems in terms of industry structure, innovation strategies, networks, markets and governmental interventions. We subsequently explore how these characteristics may influence the transition to deep decarbonization and identify gaps in the literature from which we formulate an agenda for further transitions research on EPIs and consider policy implications. Furthering this research field would not only enrich discussions on policy for achieving deep decarbonization, but would also develop transitions theory since the distinctive EPI characteristics are likely to yield new patterns in transition dynamics.
Limiting global warming to below 2 °C or even 1.5 °C requires a fundamental transformation of global socio-economic systems. This need for transformation has been taken up by international climate policy. This article synthesizes criteria of transformational change from transition research and climate finance agencies. On this basis, the article conducts a multi-criteria evaluation of the transformative potential of the European Union Emissions Trading Scheme (EU ETS), currently the world's largest market-based climate policy. From this case it can be inferred that emissions trading can "destabilize" incumbent high-emission practices, but its effectiveness in fostering innovation is limited. Furthermore, the analysis shows that details in the arrangements of the scheme such as allocation rules can have a strong detrimental impact on its outcome. If a global carbon market with a uniform price were introduced, this could lead to developing countries "buying in" with large amounts of freely allocated allowances. This, however, has been shown to thwart transformational effects and instead contribute to further carbon lock-in.
Comparing the Agenda 2030 of the United Nations and the Laudato si' by the Pope, both authored in 2015, one point stands out: the Development enthusiasm of the twentieth century is gone. In its place, we are now dealing with the demise of expansive modernity. The motto of the previous century (playing on words of the Lord's Prayer), "on Earth as in the West", now seems like a threat. The world is in crisis roundabout: the biosphere is being shattered and, in more ways than one, the gap between the rich and the poor is widening. While both publications agree that the global economic model can now be considered old iron, there are equally significant differences. While the Agenda 2030 seeks to repair the existing global economic model significantly, the encyclical calls for a pushing back of economic hegemony and for more ethical responsibility on all levels. While the Agenda 2030 envisions a green economy with social democratic hues, the encyclical foresees a post capitalist-era, based on a cultural shift towards eco-solidarity.
Organic waste to energy (OWtE) technologies have been developed and implemented in Latin America and the Caribbean (LAC) countries. However, they are still far away to significantly contribute not only to treat the ever-increasing waste volumes in the region but also to supply the regional energy demand and meet national carbon emission goals. The technical complexity of these technologies aligned with lack of research, high investment costs and political deficiencies have not allowed for an appropriate implementation of OWtE in the region, where the applicability of large-scale plants remains to be demonstrated. This research presents the state-of-the art of OWtE technologies in the context of the LAC countries based on archival research method. In addition, it presents challenges and opportunities that the region is facing for an adequate implementation of these technologies. The main findings show that OWtE have the potential to improve waste and energy systems in the region by reducing environmental impacts along with a series of social and economic benefits, such as increasing access to a sustainable energy supply. Diverse researches indicate principally anaerobic digestion, fermentation (e.g. 2G bioethanol, etc.), microbial fuel cells, gasification and pyrolysis as efficient technologies to treat solid organic wastes and produce bioenergy.
This paper reflects the socio-economic power of renewable energy production cooperatives for a wider energy system transformation in Germany. Energy cooperatives have turned into important supporters of renewable and decentralised energy structures, due to their strong growth since the year 2006, their participation in local renewable energy projects and their democratic awareness. The cooperative form of coordinating local renewable energy projects applies to a decentralised energy system that is managed by many smaller firms - a system concept that is preferred by the majority of German citizens. However, there is not enough knowledge to understand to what extent this organisational form is able to unify a broad group of actors in promoting a renewable energy system (societal power) and to gather capital for elaborating renewable energy supply structures (economic power).
The reflection is based on an empirical assessment of all energy cooperatives that were registered in Germany before 31st December 2013. Their growth dynamic and their business approaches are discussed. A special focus lies on renewable energy production cooperatives. The study presents the development of their members, their capital, their profit and loss, as well as their investment intensity over a timeframe of three years (2010-2012). The socio-economic potential of renewable energy production cooperatives for supporting a renewable energy system is discussed against the background of empirical results.
Various electricity generation technologies using different primary energy sources are available. Many published studies compare the costs of these technologies. However, most of those studies only consider plant-level costs and do not fully take into account additional costs that societies may face in using these technologies. This article reviews the literature on the costs of electricity generation technologies, aiming to determine which types of costs are relevant from a societal point of view when comparing generation technologies. The paper categorises the relevant types of costs, differentiating between plant-level, system and external costs as the main categories. It discusses the relevance of each type of cost for each generation technology. The findings suggest that several low-carbon electricity generation technologies exhibit lower social costs per kWh than the currently dominant technologies using fossil fuels. More generally, the findings emphasise the importance of taking not only plant-level costs, but also system and external costs, into account when comparing electricity generation technologies from a societal point of view. The article intends to inform both policymakers and energy system modellers, the latter who may strive to include all relevant types of costs in their models.
The "fuzzy front end" of innovation is argued to be crucial for the success and sustainability impact of a final product. Indeed, it is a promising area of focus in efforts to achieve the United Nations' 2015 Sustainable Development Goals (SDGs), which provide a globally accepted framework for sustainability. However, the usability of the 17 goals and the large number of sub-goals represent barriers to innovation practitioners. Moreover, this early innovation stage proves to be a challenge for corporate practitioners and innovators, largely due to the concept's intangible, qualitative nature and the lack of data. To help overcome these barriers, this article proposes a four-stage approach for structuring the innovation process using an online tool called the "SDG-Check", which help assess an innovator's sustainability orientation in the early phases of product and service development. It is a semi-quantitative tool to gather and combine assessments by experts involved in innovation processes with implications for the United Nations' SDGs. Furthermore, this article presents our first experiences in applying the SDG-Check based on three living lab innovation cases. The results indicate that the tools can support and inspire a dialogue with internal and external stakeholders with regards to sustainability considerations in the early design stages of product and service development.
