"Dorf ist Energie(klug)" : Abschlussbericht und Ergebnisse der wissenschaftlichen Begleitforschung
(2016)
Der Abschlussbericht mit den Ergebnissen der wissenschaftlichen Begleitforschung möchte darüber informieren, wie das Projekt entwickelt, initiiert, geplant und letztlich prozessual umgesetzt worden ist. Der erste Teil gibt insbesondere die im Prozess gewonnenen Erkenntnisse weiter und nennt erste Handlungsempfehlungen. Die darauffolgenden Kapitel bündeln die Ergebnisse der wissenschaftlichen Begleitforschung, welche zudem durch vier thematisch verschiedene Masterthesen im Untersuchungsraum ergänzt werden konnten.
Zielgruppe für die erarbeiteten Handlungsempfehlungen sind all jene, die eine strategische Planung im Bereich des Ehrenamtes und des Klimaschutzes auf lokaler Ebene in den ländlichen Räumen (Südwestfalens) anstreben. Der Abschlussbericht mit seinen Erkenntnissen richtet sich an die Personen, Gruppen und Institutionen auf regionaler Ebene, die gemeinsam mit Partnern einen ganzheitlichen Klimaschutz im Ehrenamt zur räumlichen Entwicklung und Gestaltung systematisch vorantreiben wollen und dabei ähnliche Voraussetzungen und Strukturen aufweisen. Nicht zuletzt aber auch die, die von den gelebten Projekten und den gesammelten Erfahrungen lernen möchten. Daher sind folgende Zielgruppen insbesondere angesprochen: Dorfgemeinschaften, Vereine, Ehrenamtliche Gruppierungen (Bürgerstiftungen, Genossenschaften), LEADER-Arbeitsgruppen, Landkreise, Städte und Kommunen, Regionalmanager, Energie- und Umweltbeauftragte, Klimaschutzmanager, Unternehmen der Wertschöpfungsketten Energie- und Klima und viele mehr.
Urbane Räume sehen sich verschiedenen ökologischen, sozialen und ökonomischen Herausforderungen gegenüber, für deren Bewältigung es unter anderem neue bzw. veränderte Handlungs- und Planungsansätze bedarf. Der Klimawandel mit seinen räumlich wirksamen Folgewirkungen ist eine der zentralen ökologischen Herausforderungen des 21. Jahrhunderts. Städte sind dabei sowohl Verursacher des Klimawandels als auch Betroffene. Sie sind Wohnort, Heimat, Arbeits- und Produktionsstätte. Durch ihre hohe Bevölkerungsdichte und durch die Agglomeration ökonomischen Kapitals sind Städte aber auch stark durch Extremereignisse wie Starkniederschläge und Hitzeperioden gefährdet. Grüne Infrastrukturen können daher nicht nur eine Strategie sein, um sich gegen die Klimawandelfolgen anzupassen, sondern bieten gleichzeitig das Potenzial für neue Lebensräume, um so das Artensterben zu mindern bzw. zu stoppen. Die vorliegende Konzeptstudie widmet sich der Frage, wie Straßen im Sinne des genannten Zieldreiecks weiterentwickelt und gestaltet werden können, d.h. wie eine Transformation urbaner Quartiersstraßen hin zu "lebenswerten" Stadt- und Straßenräumen erfolgen kann.
Welche Perspektiven haben zukunftsfähige und krisenfeste Städte nach der Corona-Pandemie? Antworten darauf skizzieren die Autorinnen und Autoren in dem vorliegenden Diskussionspapier. Ihre zentrale These: Städte der Zukunft müssen und werden "näher", "öffentlicher" und "agiler" sein. Dies erläutern sie anhand dieser drei Dimensionen und konkretisieren es anhand zahlreicher Beispiele.
This study is an exploratory analysis to provide a prioritisation and indication of extensiveness of review activities related to measures that currently exist for eight product groups: Domestic Washing Machines, Domestic Dishwashers, Domestic Washer-Driers, Domestic Cold Appliances, Lighting products (non-directional, tertiary and "special purpose"), Set-top Boxes. For water pumps only a review of tolerances was required.
The analysis focused on possible energy savings as basis for prioritisation, but - following the request of the European Commission made during the kick-off meeting - also considers resource efficiency aspects insofar feasible within the constraints of the study. The conclusion of this exploratory study is that for all product groups considered (except pumps) a revision of existing regulations (or introduction of new regulations) is the preferred policy option.
The analysis shows that these product groups are expected to (continue to) meet eligibility criteria for the introduction of ecodesign and/or energy labelling measures, with simple set top boxes as sole exemption as its market and environmental significance is in rapid decline (sales are expected to be marginal by 2020).
Bad Hersfeld is a small city with about 30.000 inhabitants situated in the middle of Germany. Climate Protection has been on the political agenda in Bad Hersfeld since quite a while. In 1997 the Wuppertal Institute elaborated a first energy and CO2 balance for the city, which was updated in 2007. With the compilation of the CO2 balance it was shown that the emissions in Bad Hersfeld almost stayed at a constant level between 1997 and 2006.
The result was sobering for the local authority. Although some single measures had been implemented, there was no improvement of the CO2-balance.
It was concluded that a successful climate protection strategy needs a comprehensive concept comprising all sectors and a periodic monitoring. Bad Hersfeld commissioned the Wuppertal Institute to develop feasible measures to reduce the CO2 emissions drastically and instruments to overcome existing barriers. In a close cooperation with the City Council and the local municipal utility a climate protection concept was compiled that is rather ambitious for a city of this size.
In consideration of the regional peculiarities12 concrete measures and 7 accompanying measures build the core of the concept with a main focus on energy efficiency (final energy), combined heat and power (CHP) and renewable energies. Another important part of the concept is a municipal support programme to develop the endogenous efficiency potentials and renewable energies in the region. Further to these planning instruments, information and networking activities are compiled as well as a variety of suggestions for a climate protection marketing (Wagner 2008).
Some of these measures that were developed in an iterative and cooperative process between the responsible actors in Bad Hersfeld and the Wuppertal Institute are transferable to other cities and towns. The impeding factors in Bad Hersfeld like the user-investor dilemma, the low capital of small housing associations or the large stock of listed historical buildings, are typical for cities of this size.
Urban energy systems have been commonly considered to be socio-technical systems within the boundaries of an urban area. However, recent literature challenges this notion in that it urges researchers to look at the wider interactions and influences of urban energy systems wherein the socio-technical sphere is expanded to political, environmental and economic realms as well. In addition to the inter-sectoral linkages, the diverse agents and multilevel governance trends of energy sustainability in the dynamic environment of cities make the urban energy landscape a complex one. There is a strong case then for establishing a new conceptualisation of urban energy systems that builds upon these contemporary understandings of such systems. We argue that the complex systems approach can be suitable for this. In this paper, we propose a pilot framework for understanding urban energy systems using complex systems theory as an integrating plane. We review the multiple streams of urban energy literature to identify the contemporary discussions and construct this framework that can serve as a common ontological understanding for the different scholarships studying urban energy systems. We conclude the paper by highlighting the ways in which the framework can serve some of the relevant communities.
The 2014 United Nations Climate Change Conference had been scheduled from 1 to 12 December in Lima/Peru. While in the run-up to the conference, China and the US in a surprise bilateral move had announced plans to cut greenhouse gas emissions that exceeded expectations, the conference was characterised once again by a deep division between key players from the former so-called "developed" and "developing" world. The negotiations thus took 32 hours longer than planned and ended on Sunday morning at 1.22 am. More importantly, the conference failed almost completely to resolve the tasks it was supposed to do in order to prepare the last round of negotiations before next year's conference in Paris 2015, which is supposed to deliver a comprehensive future climate agreement. A team of researchers from the Wuppertal Institute attended the conference and have compiled a first assessment of the results.
Conventional new buildings in OECD countries with a history of building codes save about 50 % of energy compared to average buildings in the building stock. This improvement, however, is not enough to create a building standard with low lifetime costs nor to reach long-term climate protection targets. Much higher energy savings can already be achieved through proven high-efficiency building concepts bringing net economic benefits among other advantages.
A strategic approach to integrated building design is the key to achieving these high-energy savings at low or no extra cost in residential buildings. In our paper we describe the "Easy Efficiency Approach", which can reduce primary energy consumption by 40 to 60 % compared to conventional new building standards, or by 70% to 80% when compared to the primary energy consumption of the existing building stock, and should be regarded as the minimum. This strategy focuses on low-cost options, mainly passive options. Although it can already significantly reduce energy consumption, this first step will not be sufficient to reach long-term climate protection goals. It is thus necessary to implement and support what we call an "Advanced Efficiency Approach", with savings up to 90% , as compared to new building standards, as soon as possible to avoid lock-in effects. Further improvements, especially through the active use of renewable energies, reduce the net primary energy demand to 0 % and beyond.
According to the chosen strategy clearly defined energy performance ranges, with reference to possible savings, for different climate zones worldwide are given. In verifying this approach simulations with BAT (Best Available Technologies) buildings of different types (single family, multi family, high rise) were carried out in close cooperation with project partners. This data has also been verified through an empirical database of built examples both for energy consumption as well their economic soundness.
The study "A Green New Deal for Europe" consists of two basic elements: Firstly it aims to cope with the economic crisis through intensive measures in order to systematically stimulate the eco-industries, to create jobs and to boost economic recovery. Secondly it aims at establishing the foundation for a green modernisation of the European economy. The study examines existing EU strategies policies and programs concerning their suitability to implement the Green New Deal. It proposes exemplary measures in the field of energy, mobility and resource use. The study has been compiled by the Wuppertal Institute on behalf of the Greens/European Free Alliance (EFA) Group in the European Parliament.
Agriculture is a major sector responsible for greenhouse gas emissions. Local food production can contribute to reducing transport-related emissions. Since most of the worldwide population lives in cities, locally producing food implies practicing agriculture in urban and peri-urban areas. Exemplary, we analyze the potential to produce fresh vegetables within Berlin, Germany. We investigate the spatial extent of five different urban spaces for soil-based agriculture or gardening, i.e., non-built residential areas, allotment gardens, rooftops, supermarket parking lots, and cemeteries. We also quantify inputs required for such food production in terms of water, human resources, and investment. Our findings highlight that up to 82% of Berlin’s vegetable demand could be produced within the city, based on a reasonable validation of existing areas. Meeting this potential requires 42 km2 of urban spaces for cultivation, a considerable amount of irrigation water, around 17 thousand gardeners, and over 750 million EUR of initial investments. The final vegetable cost would be around 2 EUR to 10 EUR per kg without any profit margin. We conclude that it is realistic to produce a significant amount of Berlin's vegetable demand within the city, even if it comes with great challenges.
A learning experience : integrating theory and practice for the implementation of INDCs ; thinkpiece
(2016)
A major cornerstone on the way to low-carbon sustainable development on a global scale will be a swift and effective implementation of all countries' INDCs submitted to the UNFCCC prior to Paris. However, doing so will require transforming development pathways away from currently pervasive carbon lock-ins. This can only be successful if countries take a systemic view on their development agendas, and link mitigation, adaptation and other developmental priorities together for a coherent overarching sustainable development strategy. The ownership for this process needs to be with the countries themselves as such strategies touch fundamentally upon national policy-making and implementation. At the same time, developing countries have access to bi- and multilateral financial and technical cooperation. To enable a systemic, country-led perspective, development cooperation needs to shift its paradigms away from currently prevalent project-level interventions.
A truly innovative and transformational shift with the objective of pursuing a low-carbon and climate resilient society needs to open up space for experimentation as new ways of doing things need to be put into practice. Experiments will not always be successful, but foster learning on a national as well as an international level on pitfalls and solutions in new approaches to low-carbon sustainable development. Not least, there needs to be a renewed focus on programmatic approaches that link various topical domains for a country-led process, and a critical look at development work that is "doomed to succeed".
Our article draws from systems theory, development studies and recent work on transitions studies and transformational change in the international domain. It links up different theoretical concepts with practical approaches in order to outline a future development agenda that will be owned by developing countries and supported non-invasively by bi- and multilateral development cooperation to foster low-carbon development pathways that are urgently needed to solve the climate crisis.
Optimization and simulation models are fit to work on a multitude of technical, economic, and techno-economic questions. However, they are by now not able to satisfactorily include societal aspects like acceptance, spatial implications and legal frameworks. In order to advance scope and explanatory power of simulation models, collaboration in interdisciplinary research teams is needed. Yet the exchange in such teams and its coordination can prove challenging. Furthermore, disciplinary approaches and methods for simulation and optimization might not be familiar to all participants.
To this end, a new conceptual model is introduced. The conceptual model employs few basic elements and concepts for describing and explaining arbitrary societal and technical relationships. Most notably, the conceptual model is general in its design, so contributions to the problem formulation and design components can be made by all team members regardless of their discipline. The procedure is based on common agent-based concepts without using their terminology. Consequently, an exchange among all team members becomes possible without them necessarily being proficient in agent-based modeling. A reduced presentation of workshop results exemplifies the use of novel elements for deriving an emergent agent-based simulation.
Much of the current literature on climate clubs sees mitigation costs creating free rider incentives as the main problem of climate policy. Climate clubs are supposed to solve this problem by creating additional incentives for mitigation. Looking more in detail, one sees that the situation differs from sector to sector. Some industry sectors indeed have substantial cost and competitiveness issues. In others such as electricity and transport, there are costs at micro level but balance for economy and society as a whole is rather positive. International climate policy in general and clubs in particular should therefore be tailored to sectoral specifics.
This article develops a sectoral approach to the analysis of global climate governance. This approach advances the assessment of global climate governance by focusing on complexes of intergovernmental and transnational institutions co-governing key socio-technical sectoral systems. The actual and potential contribution of these sectoral institutional complexes to advancing decarbonization can be assessed according to five key governance functions: (1) providing guidance and signal to actors, (2) setting rules to facilitate collective action, (3) enhancing transparency and accountability, (4) offering support (finance, technology, capacity-building), and (5) promoting knowledge and learning. On this basis, we can assess the potential of international cooperation to address the challenges specific sectoral systems face in the climate transition as well as the extent to which existing sectoral institutional complexes deliver on this potential. This provides a solid starting point for developing options for filling identified gaps and enhancing the effectiveness of global climate governance.
A sectoral perspective on international climate governance : key findings and research priorities
(2021)
This concluding article derives six major findings from the contributions to this special issue. First, the barriers and challenges to decarbonisation vary significantly across sectoral systems. Second, and similarly, the need and potential for the five functions of international governance institutions to contribute to effective climate protection also vary widely. Third, while the pattern is uneven, there is a general undersupply of international climate governance. Fourth, the sectoral analyses confirm that the UNFCCC and Paris Agreement play an important overarching role but remain limited in advancing effective sectoral governance. Fifth, while non-environmental institutions may present important barriers to decarbonisation, more synergistic effects are possible. Sixth, our sectoral approach provides a sound basis on which to identify sector-specific policy options. The paper then offers reflections on the merits and limitations of the sectoral approach, before identifying avenues for future research to further advance the agenda.
Article 6.4 of the Paris Agreement establishes a new mechanism for Parties to cooperate in achieving their nationally determined contributions (NDCs). One key innovation of the Article 6.4 mechanism is its objective to "deliver an overall mitigation in global emissions" (Art. 6.4(d)). This report develops recommendations on how to implement this objective. A key difficulty lies in the fact that even basics of how the mechanism is supposed to function have so far not been clarified by the Parties. The report therefore first sketches out what has so far been agreed and discussed on the mechanism’s activity cycle. Second, as the concept of overall mitigation has so far also not been clearly defined by Parties, the report derives a working definition from the language that was agreed in the Paris Agreement. In the next step, the report provides a survey of the options to achieve overall mitigation that have so far been discussed in the relevant literature and in the Article 6 negotiations. Many of these options were developed in the context of the Kyoto mechanisms. The report therefore discusses to what extent the options are also applicable under the Paris Agreement or whether adjustments need to be made. In the following, the options that are applicable under the Agreement are assessed on the basis of a number of criteria. The report concludes with a summary of the main findings and recommendations.
Achieving sustainable mobility in developing countries : suggestions for a post-2012 agreement
(2009)
In December 2009, countries meet in Copenhagen to establish a new global climate agreement. This article links the need for reducing transport-related greenhouse gas emissions in developing countries with the current international climate negotiations. Arguing that a sustainable transport approach requires comprehensive policy packages, it assesses the suitability of current climate negotiation proposals in promoting sustainable transport. The project-based approach under the current climate regime incentivises neither comprehensive sustainable transport and mobility policies, nor sufficient numbers of local projects. Current proposals to increase efforts by developing countries, to reform the Clean Development Mechanism, and to create new emission trading mechanisms are promising but still have to overcome several obstacles. One obstacle involves how to properly assess the impact of actions while maintaining streamlined procedures. The authors conclude from their analysis that the best way forward would be to establish an international mitigation fund with a dedicated transport window financed by industrialised countries. This fund would enable developing countries to implement national policies and local projects. Developing countries would outline low-carbon development strategies, including a sectoral strategy for low-carbon transport.
This policy paper reviews the concept of additionality in the context of the Paris Agreement. Additionality is a key criterion that helps to maintain the environmental integrity of the Paris Agreement, especially when units created under Article 6.2 or 6.4 are used for offsetting purposes whether that is by Parties in order to meet their NDCs or whether by other entities with legal mitigation obligations.
It does so by first reviewing key concepts such as offsetting, environmental integrity, and baseline. Subsequently, it explores the context of additionality under the Paris Agreement. More specifically it discusses what should be counted as the baseline for additionality demonstration. The subsequent chapter then highlights the challenges with establishing additionality, that is establishing a causal relationship between a policy intervention and a proposed activity. Finally, the Policy Paper discusses aspects of international governance with respect to additionality.
Additionality revisited : guarding the integrity of market mechanisms under the Paris agreement
(2019)
The Paris Agreement requires mitigation contributions from all Parties. Therefore, the determination of additionality of activities under the market mechanisms of its Article 6 will need to be revisited. This paper provides recommendations on how to operationalize additionality under Article 6. We first review generic definitions of additionality and current approaches for testing of additionality before discussing under which conditions additionality testing of specific activities or policies is still necessary under the new context of the Paris Agreement, that is, in order to prevent increases of global emissions. We argue that the possibility of "hot air" generation under nationally-determined contributions (NDCs) requires an independent check of the NDC's ambition. If the NDC of the transferring country does contain "hot air", or if the transferred emission reductions are not covered by the NDC, a dedicated additionality test should be required. While additionality tests of projects and programmes could continue to be done through investment analysis, for policy instruments new approaches are required. They should be differentiated according to type of policy instrument. For regulation, we suggest calculating the resulting pay-back period for technology users. If the regulation generates investments exceeding a payback period threshold, it could be deemed additional. Similarly, carbon pricing policies that generate a carbon price exceeding a threshold could qualify; for trading schemes an absence of over-allocation needs to be shown. The threshold should be differentiated according to country categories and rise over time.
Addressing opportunities and challenges of a sectoral approach to the Clean Development Mechanism
(2005)
More and more countries are incorporating the instrument of emissions trading into their national climate policies. This emerging mosaic of emissions trading schemes (ETS) raises the question of whether they should be linked with each other. From an economic point of view, linking of domestic schemes is supposed to increase the economic efficiency of carbon markets. In addition, linking is also expected by some to yield substantial political benefits in terms of the evolution of the UNFCCC/Kyoto regime. However, these optimistic prospects are based on a best-case scenario where all major countries establish environmentally effective emissions trading systems and then link them with each other. Real-life politics might develop rather differently. This paper therefore examines to what extent the current status of emissions trading in industrialised countries provides a basis for reinforcing and moving forward the international climate regime through linking domestic ETS. After comparing emerging emissions trading schemes from an institutional perspective, it emerges that not only emissions trading is at a very early stage in most countries, in addition the emerging systems are probably going to be designed very differently from the EU ETS. While for some design features such as the coverage design differences do not matter, there are some areas where the plans in many non-EU countries look crucially different from the EU system. The outlook for a linked international ETS is therefore currently still very uncertain. Given this state of affairs, the EU should pro-actively engage with the non-EU countries to try to harmonise their developing national emissions trading schemes with the EU ETS, widely disseminate the lessons it has learned from the EU ETS, strongly make the case for environmental integrity and at the same time make clear that systems that want to link to the EU ETS will need to meet certain quality criteria.
Warum sollten Strom- und Gasunternehmen ihre Kundinnen und Kunden beim Energiesparen durch effizientere Technik unterstützen? Warum sind die Anreize des Marktes zu schwach, und wie sollte daher die Politik förderliche Rahmenbedingungen für die Energiewirtschaft schaffen? Dem geht dieses Buch mit einer Analyse sinnvoller Politikpakete und wirtschaftlicher Effekte sowie mit einem Vergleich der politischen Rahmenbedingungen in Belgien, Dänemark, Großbritannien und den Niederlanden auf den Grund. Die Untersuchung zeigt, dass mit gut gestalteter Politik jährlich bis zu 1,5 Prozent Energie zusätzlich und wirtschaftlich eingespart werden kann. Der Vergleich liefert 44 Schlussfolgerungen zu Erfolgsfaktoren und die Grundlage zu Empfehlungen für die Politik in Deutschland.
