This thesis justifies and develops a sustainable level of Lifestyle Material Footprint (LMF) as a benchmark for designing sustainable lifestyles. It shows the application of the benchmark in a Household-level Sustainability Transition method and presents a framework for inspiring design solutions towards a Design for One Planet (Df1P).
The thesis shows how the Material Input per unit of Service (MIPS) concept has developed from product orientation to the application to household consumption and from technically-focused measurement into an integral part of methods for designing one-planet lifestyles and supporting solutions. This provides both an advanced application of the concept and its opening to new purposes and users.
The core of the thesis is the suggestion of a sustainable material footprint benchmark of 8 tonnes per person per year as a resource cap target for household consumption in Finland, an 80% (factor 5) reduction from present average. The 8 tonnes benchmark opens the possibility for a target-oriented, planned reduction of LMFs by target-setting, experimenting and up-scaling of sustainable solutions. The method enabled the participating households to perform footprint reductions of 26–54% during the one-month experiment phase. Notable footprint reductions are thus possible even in the short term, which is an important message to other households and other actors in society. Calculating households' LMFs makes visible the structures underlying household consumption and the need for change not only in household consumption but also in the supply of products, services and infrastructure, and thus systemic changes initiated by others than households.
The orientation framework of Df1P suggests measures that could be promoted by means of design, and structures them in a matrix incorporating priority action areas in the fields of housing, nutrition and mobility, and the domains of product design, service design, infrastructure planning and communication design. Mainstreaming sustainable lifestyles will potentially require a new design culture, but at least significant efforts in product design, service design and infrastructure planning as well as in making sustainable solutions attractive to consumers and disrupting existing routines. The more technology and infrastructure can be integrated into this change, the more space will be left for individual diversity in achieving sustainable household consumption. The orientation framework could provide a first step towards Df1P practice by inspiring designers to integrate the recognition of the planetary boundaries into their work.
Water is a basis for life and ecosystem health. And water, especially in regions affected by water scarcity, is a highly contested and politicised natural resource. The state-of-the-art in sustainable water resources management requires collaborative approaches that foster the integration of conflicting interests of multiple stakeholders. Achieving integration in complex and contested real life situations however remains a major challenge. Boundary work can facilitate this ambitious goal. This study evolves boundary work science to improve collaboration in the water sector. It develops a framework for boundary work that enables understanding, structuring and approaching barriers for collaborative water resources management. A case study from the Garden Route region, South Africa gives a grounded basis for the conceptual developments and further provides in-depth insights into reasons and obstacles for collaborative water resources management in a contested local case. The case study serves both: An intrinsic analysis of a conflictive case, and conceptual developments to the boundary work framework - tested against local realities.
The transformation of cities towards sustainable and inclusive development is a key objective of the New Urban Agenda (United Nations 2017). Transport infrastructure is a critical factor in shaping cities, determining the energy intensity of mobility and providing access to essential social and economic opportunities. The sector also plays an important role in global climate change mitigation strategies, as it currently accounts for about 23% of global energy-related greenhouse gas emissions (IPCC 2014).
There is substantial potential to improve urban access, air quality, safety and the quality of life in cities along with reducing Greenhouse Gas Emissions if an integrated policy approach is applied that combines all intervention areas for transport policy and involves all levels of government. A package that achieves low-carbon transport and fosters sustainable developed includes avoided journeys through compact urban design and shifts to more efficient modes of transport, uptake of improved vehicle and engine performance technologies, low-carbon fuels, investments in related infrastructure, and changes in the built environment. From a governance perspective, all relevant political institutions at the local and national level need to be involved in the coalition building along with key societal actors, such as unions, industry and civil society organisations. Bringing the policy objectives of these actors together with an integrated policy package is a vital step towards a low-carbon, sustainable mobility system.
Policy design and governance are critically interlinked as the ability of institutions to find a political consensus and to maintain policy stability heavily influences the success of measures to shape the transformation pathway towards sustainable mobility. This thesis aims to analyse these linkages and highlight the role of different policy and governance approaches. This analysis builds on transport and urban development research, but takes a transdisciplinary research perspective, building on the Multi-Level-Perspective on sustainability transitions (Geels 2002) and aims to highlight the potential for a consensus oriented policy approach (Lijphard 1999) that builds on co-benefits among key policy objectives and coalitions among key political actors, which leads to the main question for this thesis and the focus areas for the analysis.
Several countries with large coal deposits but limited domestic oil reserves show high interest in coal-to-liquid (CtL) technologies, which could reduce crude oil imports by converting coal into liquid hydrocarbon fuels. After decades of successful large-scale operating experiences in South Africa, CtL activities in the United States, China and Germany have been fanned by the high oil price in the last years. However, CtL indicates negative techno-economic and resource-related features, such as high capital costs, high greenhouse gas discharges and high water consumption. Therefore, the technology's diffusion strongly depends on a favourable framework of policies and strong technology advocates. Daniel Vallentin analyses interdependencies between technical and non-technical parameters affecting the diffusion of CtL technologies in the United States, China and Germany. Applying the inter-disciplinary technological system approach, he identifies factors which determine the market prospects of CtL in these countries, including costs, the geographic distribution of coal reserves, actor constellations and technology, energy and climate policies. At the end of his study, he derives general conclusions with regard to driving forces and barriers for CtL diffusion. As the investigated countries are major consumers of energy and belong to the world's largest emitters of greenhouse gases, their strategies in substituting crude oil based fuels are of utmost global relevance. Therefore, Vallentin's study is recommended to experts, planners, decision-makers, and politicians in the field of climate and resource protection.
Shifting the resource base for chemical and energy production from fossil feedstocks to renewable raw materials is seen by many as one of the key strategies towards sustainable development. The utilization of biomass for the production of fuels and materials has been proposed as an alternative to the petroleum-based industry. Current research and policy initiatives focus mainly on the utilization of lignocellulose biomass, originating from agriculture and forestry, as second generation feedstocks for the production of biofuels and electricity. These activities act on the assumption that significant amounts of biomass for non-food purposes are available. However, given a certain productivity per area, the current massive growth in global biofuels demand may in the long term only be met through an expansion of global arable land at the expense of natural ecosystems and in direct competition with the food-sector. Although many studies have shown the potential of biofuels production to reduce both, greenhouse gas emissions and non-renewable energy consumption, these production routes are still linear processes which depend on significant amounts of agricultural or forestry production area. Cascading use, i.e. when biomass is used for material products first and the energy content is recovered at end-of-life, may provide a greater environmental benefit than primary use as fuel. Considering waste and production residues as alternative feedstocks could help to further reduce pressures on global arable land. This research focused on thermochemical and biochemical technologies capable of utilizing organic waste or forestry residuals for energy, chemical feedstock, and synthetic materials (polymers) generation. Routes towards synthetic materials allow a closer cycle of materials and can help to reduce dependence on either fossil or biobased raw materials. The system-wide environmental burdens of three different technologies, including (1) municipal solid waste (MSW) gasification followed by Fischer-Tropsch synthesis (FTS), (2) plasma gasification of construction and demolition (C&D) wood for syngas production with energy recovery, and (3) forest residuals use in a biorefinery for polyitaconic acid (PIA) production, were assessed using life-cycle assessment. The first two studies indicated that MSW gasification and subsequent ethylene and polyethylene production via FTS has lower environmental impacts than conventional landfilling. In the future, as societies may shift towards the use of renewable energy, power offset by conventional waste-to-energy systems would not be as significant and chemicals production routes may then become increasingly competitive (in terms of environmental burdens) also to waste incineration. While production cost of Fischer-Tropsch derived chemicals seems not yet competitive to fossil-based chemicals provision, future price increases in global oil prices as well as changes in waste tipping fees, and efficiency gains on site of the waste conversion systems, may alter the economics and allow carbon recycling routes to reach a price competitive to fossil-based production routes. The third study found that plasma gasification of C&D wood for energy recovery has roughly similar environmental impacts than conventional fossil-based power systems. However, process optimization with respect to coal co-gasified, coke used as gasifier bed material, and fuel oil co-combusted in the steam boiler, would allow to significantly lower the system-wide environmental burdens. The fourth study looked at PIA production from softwood hemicellulose in a stream integrated approach (with the partially macerated wood and lignin being used in other existing processes such as pulp & paper plants for conventional pulp and bioenergy production). The assessment indicated lower global warming potential, energy demand, and acidification, for the wood-based PIA polymer, when compared to corn-based PIA and fossil-based polyacrylic acid (PAA). However, water use associated with wood-derived PIA was found to be higher than for fossil-based PAA production and land occupation is highest for the wood-derived polymer. It is hoped that results of this dissertation will add to the current debate on sustainable waste and biomass utilization and to establish future supply chains for green and sustainable chemical products.
The adverse environmental impacts from inefficient building construction increase if measures to reduce energy and resource use, through stringent building policies and efficient technology, are not implemented in developed and developing countries. To illustrate a holistic approach to reducing buildings' energy and resources, the comparison of energy efficient and green buildings in terms of their technological aspects and their policy context in developed and developing countries, mainly in Europe, the USA and India, is presented together with a policy package recommendation for Nepal. A quality review of multiple literature sources, supported by various expert opinions, were the methods used for this in-depth analysis.
It discusses that mandatory building standards, voluntary labels, information instruments and financial incentives are the most effective combination for the shift towards market transformation, that results in a higher share of energy efficient and green buildings. The lesson such as higher compliance with, and enforcement of, building energy standards can be seen in developed countries (e.g. Germany). Looking at a building's life cycle perspective, it is not sufficient to focus solely on operational energy reduction in higher energy efficient buildings as this is achieved by the increased use of energy intensive materials. Green requirements must be considered in updating building energy standards and labels, particularly for developed countries. Green building certification will also become more effective when the stringency of energy standards is higher and when the whole building life cycle assessment is considered. Due to the increasing scarcity of energy and resources, many developing countries are forced to face up to the need for holistic green buildings. Although baseline standards are not as high as in most developed countries and national financial support is low, the gradual move towards making the standards more stringent and incorporating the wider scope of resource saving are positive developments in developing countries (e.g. India). However, to achieve significant success, strategies must include the establishment of a suitable funding environment, a political commitment and a strong government vision for long term and sustainable building construction. The challenges faced by Nepal are even greater due to the fast pace of urban growth and the absence of energy and resource efficient buildings policies, highlighting the need for an effective policy package. Overall, this dissertation demonstrates how energy efficient and green buildings are interlinked. Green buildings reinforced with higher levels of energy efficiency and energy efficient buildings incorporating green requirements are stepping-stones for achieving greater building energy and resource efficiencies. And a suitable policy package fosters its development.
Enhancing cross-functional integration in new product development becomes increasingly important for industrial players to keep up with shorter product life cycles in technological innovation dynamics. Abundant research reflects the topic's significance, yet ambiguity in empirical results persists and industrial adoption of existing methods remains incremental. This thesis employs a qualitative approach to build a case study at the design-manufacturing interface of new product development of electrified cars. Cross-functional coopetition, as the joint occurrence of cooperation and competition, is adopted to generate an in-depth understanding of integration dynamics. Socio-organizational and contextual aspects are found to shape integration in a new product development context substantially. A model of interface dynamics is developed which provides for analysis and prediction of these aspects' impact on effective integration. A grounded theory approach to enhance integration is explored that introduces constraints as stimuli to consider manufacturability aspects in the design process. Constraint introduction is found to positively impact both cross-functional integration and creativity, with eight characteristics of constraint quality identified as moderating factors. A theoretical model is contributed which outlines cause-effect relationships of constraints' impact on antecedents of new product development success. It substantiates constraints' role in innovation contexts and encourages application for design-manufacturing integration as well as for other interfaces or purposes.
The earth as we know it can only continue to exist if humanity finds a way to switch to a sustainable use of energy and resources. This work contributes to the research carried out to achieve this goal by improving the coating of adsorptive materials. These are used in heat transformation and drying processes that allow for efficient temperature and humidity control in buildings. A central component of these adsorptive coatings is the binder that acts as "glue" in the manufacturing of the coating. In this work the methods to evaluate binder performance regarding their thermal stability under the process conditions, their mechanical stability and their influence on the adsorptive properties of the coating were established. The coatings have to meet special requirements due to the thermal stresses and low pressure atmosphere they experience in these applications. A selection of silicone binders was then characterized with the established tests according to these requirements. Additionally a selection of inorganic binders was investigated because they allow for the use of high desorption temperatures and thus a high energy efficiency of the process. Out of these binders Silres® MP50E emerged as the most promising one due to very good adsorptive properties of the coating, its good temperature stability and ease of use. While some of the inorganic binders showed very good adsorptive properties and temperature stability the mechanical stability of all inorganic binders was not sufficient for their use in adsorption heat transformation technology. This is the first time that a broad selection of binders was evaluated with regards to adsorptive coatings and the results published in literature. With a suitable binder identified, the next step was to optimize the coating of the heat exchangers in order to work out how to manufacture the most efficient and powerful heat exchangers. Samples with different coating thicknesses were manufactured in small scale and full scale and their adsorption behavior was characterized. It could be shown for the first time that it is possible to increase energy efficiency by improving the mass ration of adsorber to coating and increase the delivered power at the same time. This was shown for small and full scale samples. It was shown that under the corresponding conditions the heat transfer from the coating layer to the adsorber metal substrate is the limiting step in the process. These results can now be used for the planning and construction of adsorbers. With knowledge of a suitable binder and how to coat efficient, powerful adsorbers, the coating process itself was improved to allow for industrial scale manufacturing. A central point here is the ability to control slurry rheology. Out of many rheology additives those that are suited for the application in adsorption heat transformation were identified and their influence on the slurry rheology thoroughly characterized. Additionally the process of slurry preparation could be simplified for several different adsorbents. Here it was shown that the supersonic deagglomeration step is not necessary to prepare a slurry. Extending the possible coating techniques and in addition to the dip coating process used so far, the spray coating of adsorptive coatings was established for the first time in literature. This process is widely used in the industry and allows for easier plugin into existing coating processes. For the coating of high resolution patterns a proof of concept of the screen printing process was carried out.
Increasing concerns regarding the world's natural resources and sustainability continue to be a major issue for global development. As a result several political initiatives and strategies for green or resource-efficient growth both on national and international levels have been proposed. A core element of these initiatives is the promotion of an increase of resource or material productivity. This dissertation examines material productivity developments in the OECD and BRICS countries between 1980 and 2008. By applying the concept of convergence stemming from economic growth theory to material productivity the analysis provides insights into both aspects: material productivity developments in general as well as potentials for accelerated improvements in material productivity which consequently may allow a reduction of material use globally.The results of the convergence analysis underline the importance of policy-making with regard to technology and innovation policy enabling the production of resource-efficient products and services as well as technology transfer and diffusion.
In 2009, the German government launched its "National Development Plan for Electric Mobility" which set the concrete target of having 1 million electric vehicles on the road by 2020. However, there have been hypes around e-mobility before and even if this goal were to be reached, a merely quantitative aim of a certain number of electric vehicles will not suffice to contribute to a more sustainable development in transport. This requires a more comprehensive vision of sustainable e-mobility as a system innovation. Thus, the question addressed in this thesis is: How can we assess - at this critical early stage - whether there is potential for e-mobility developing as a sustainable system innovation? A theoretical framework will be developed for assessing the potential of a wider transition at an early stage by analyzing current patterns of socio-technical co-evolution and embedding these in a wider framework of the structural dynamics involved in transitions. The aim of the analysis is to identify whether 'system-innovative' projects do emerge in the case of Germany/Baden-Württemberg and what patterns (e.g. in terms of specific actor constellations, institutional adjustments etc.) can explain this. It will be shown that the system-innovative potential of this e-mobility niche remains limited, due to the powerful influence of incumbents, conflicting political goals and traditional science approaches. A few more system-innovative activities emerge where powerful actors from outside are involved, who are capable of viewing mobility in a more systemic way (e.g. actors from the public transport or housing sector). It is argued that the role of large demonstration projects is important, but they need to be designed as transdisciplinary research projects from the beginning.
Most air-conditioned buildings in India operate as Mixed-Mode Buildings (MMBs), either fully air-conditioned or with natural ventilation depending on the weather. Energy consumption for space cooling is a vital end-use service in buildings. Air-conditioning is expected to increase significantly due to high growth estimates in building construction, sales of Room Air-Conditioners (RACs), and real income growth. Therefore, this thesis examines the most influential design and control parameters that influence the potential of MMBs in India in relation to their thermal and energy performance. The primary features of MMBs analysed in the research project are as follows: shutting windows at night makes night ventilation redundant; natural ventilation through ceiling fans and windows is utilised to maintain optimal thermal conditions in naturally-ventilated mode and RACs are employed in air-conditioned mode. This thesis poses three research questions and aims to answer them. Firstly, what are the research gaps in assessing thermal and energy performance in mixed-mode buildings in India? Secondly, what is their potential concerning key operating conditions, and which parameters affect this potential? Lastly, how can these influential parameters be optimised? To answer these questions, three research methods were employed: 1) literature review; 2) large-scale simulation of building energy performance combined with uncertainty and sensitivity analysis; and 3) field studies of user behaviour with regards to RACs and the impact of ceiling fans and RACs on indoor conditions and energy consumption. The study identifies the cooling set point temperature as the most influential control parameter. In general, input parameters related to building design, shape and geometry were considered more important than those related to construction parameters. Furthermore, the study highlights that a set point temperature of 28 or 30°C is sufficient to maintain indoor comfort according to the Indian Model for Adaptive Comfort (IMAC) for residential buildings. If a specific airflow is required, it would use the least energy to run the ceiling fan at a low speed, usually set at 1.
The ongoing increase of the world population entails huge challenges for all countries' agro-food systems. Agriculture has to satisfy growing food requirements both in quantitative and qualitative terms, but the on hand natural resource stock is quickly depleting. Moreover, food production and energy production from biomass are competing for land. The thesis aims at measuring the environmental impact of nutrition in three agri-food systems. The study considers the amount of natural resources used in the production and consumption of food along its life-cycle. It is featured in two parts. In the first one the analysis is restricted to the supply chain of food, and provides a sustainability rating of thirty-seven products, grown through different agricultural practices. The second analysis takes into consideration all the value chain according to three paradigms of agri-food systems. They refers to different models of food production and consumption, observed in Italy. The first one is the dominant paradigm, including conventional and intensive farming practices, long and globalized food chains, retailing in supermarkets. The other models refer to Alternative Food Networks (AFN). The first is the GAS (Gruppi di Acquisto Solidali) initiative, i.e. solidarity purchasing groups, that manage collectively the purchasing of organic food and natural manufactured products mainly from local enterprises and farmers. They aim at accessing high quality and naturally grown food, avoiding the retailing passage and ensuring a fair price to the farmers. The third model refers to UPM (Un Punto Macrobiotico), an international association established in the Marche region in 1980. It manages and controls an entire food chain, since the agricultural production, based on the post-organic technique "Ma-Pi polyculture", till the food purchasing and catering, in sixty-three restaurants spread in the Italian territory. UPM is a very consumer-oriented food chain, in which a very exigent demand (in terms of food naturality and healthiness) drives the agricultural production towards the minimization of the external inputs employment. A further model concerns the reduction of the "Food Miles", i.e. the kilometres covered by food, since the dominant paradigm. Thus, in this model the distances are reduced by an average 90%, while the production practices do not change. The methodology used for assessing the sustainability of food is the Material Input Per Service unit (MIPS) indicator. It estimates the overall environmental pressure caused by products or services by indicating the life-cycle-wide consumption of natural resources in relation to the benefit provided. It includes five resource categories: abiotic and biotic materials (renewable resources), water, air and soil. Results of the first analysis provide a dataset of the material intensity of Italian agricultural products and foodstuffs, which can expedite future research on the topic of nutrition’s sustainability. The second analysis evaluates the natural resource demand for feeding one person during a week, in the paradigms under investigation. With respect to the dominant, the GAS model allows a 58% reduction in the abiotic resource demand, 53% in water and 71% in air. The UPM system, instead, permits a tenfold reduction in abiotic, biotic and water, and 82% decrease in the air category. The insight on the socio-economic features of the systems, together with the environmental sustainability measurement, allowed making some general conclusions and policy recommendations on the sustainability of the different food systems. The role of a low external input technology in agriculture is emphasized as a possible strategy for driving food system towards more sustainable patterns and empowering the small-scale farming.
The rising global demand for metals in a context of declining ore grades is driving the opening of new mines and the expansion of existing ones, disturbing substantial land areas (especially by open pits). However, how much land is currently disturbed globally? How much land could be disturbed by metal mining in 2050? This study investigates the global area disturbed by mining of iron, bauxite, copper, gold, and silver for the first time. The first part consists of the calculation of the specific land requirements, i.e. the area newly disturbed caused by the ore extraction at the mine site. The second part addresses the global area disturbed in the year 2011 whereas the third presents scenarios of how such area might evolve until 2050. The last part addresses the current and future pressures on global biodiversity by metal mines and shows possibilities for the future opening of new mines in low biodiversity areas, alleviating pressures in high biodiversity ones. This study presents the findings of the author´s dissertation hoping they are used as a frame to develop policies and incentives to reduce the amount of area directly disturbed by mines and their pressures on biodiversity.
A fundamental change in societal values and economic structures is required to address increasing pressures on ecosystems and natural resources. Transition research has developed in the last decades to analyze the co-dynamics of technological, institutional, social and economic elements in the provision of key functions such as energy, water and food supply. This doctoral dissertation provides conceptual and methodological contributions to the pro-active governance of sustainability transitions. Three research gaps are identified that are addressed in this dissertation. First, a comprehensive conceptualization of learning in sustainability transitions is currently missing that comprises learning at multiple societal levels (ranging from individuals to policy-actors). Learning concepts are often not explicitly discussed in transition research even though learning is considered as fundamental for innovation processes, niche formation and development as well as breakthrough and diffusion of innovations. Second, methods for the analysis and design of transition governance processes are lacking that specify case-specific intervention points and roles of actors in the implementation of innovations. Third, participatory modeling approaches are only applied to a limited extent in transition research despite a high potential for supporting communication and learning. The conceptualization of multi-level learning developed in this doctoral research conceptualizes learning at different societal levels as specific learning contexts ranging from individual and group contexts to organizational and policy contexts. The conceptual framework further differentiates between learning processes, intensity, objects, outcomes, subjects and factors, allowing for a more detailed analysis of learning within and across learning contexts. Thus, learning contexts can be linked by processes that involve actors from different learning contexts (e.g., community groups and policy-makers), as well as exchanges of physical aspects, institutions and knowledge (in the form of "learning factors"). This research has also provided a classification of model uses in transition research that supports a purposeful discussion of the opportunities of modeling and promising future research directions. The methodology developed in this doctoral research aims at the analysis and design of transition governance processes by specifying the various opportunities to contribute to sustainability transitions through purposeful action at different societal levels, as well as related roles of stakeholders in implementing such processes of change. The methodology combines different streams of previous research: 1) a participatory modeling approach to identify problem perceptions, case-specific sustainability innovations as well as related implementation barriers, drivers and responsibilities; 2) a systematic review to identify supportive and impeding learning factors from the general literature that can complement case-specific factors; and 3) a method for the analysis and design of case-specific transition governance processes. Three case studies in Canada (topic: sustainable food systems), Cyprus (water-energy-food nexus) and Germany (sustainable heating supply) have been selected to test and iteratively develop the methodology described above. The results for each case study reveal that there are learning objects (i.e., learning requirements) in all learning contexts, which underscores the importance of multi-level learning in sustainability transitions, ranging from the individual to the group, organizational and policy levels. Actors have various opportunities to actively facilitate societal transformations towards sustainable development either directly through actions at their particular societal levels (i.e., context-internal learning) or indirectly through actions that influence learning at other societal levels. In fact, most of the learning factors require cooperation across learning contexts during the implementation process. The comparing of learning factors across case studies underline the importance of several factor categories, such as "physical a disturbance or crisis", "information and knowledge". Of the 206 factors identified by stakeholders, 40 factors are case-specific and not contained in the general, review-based factor list. This underscores the value of participatory research, as general, top-down analyses might have overlooked these case-specific factors. The methodology presented in this dissertation allows for the identification and analysis of case-specific intervention points for sustainability transitions at multiple societal levels. The methodology furthermore permits the analysis of interplay between individual, group, organizational and policy actions, which is a first step towards their coordination. The focus on sustainability innovations links the broad topic of sustainability transitions to a set of opportunities for practical interventions and overcoming their implementation barriers. The methodology presented allows for the analysis and design of these interlinkages between learning contexts. While the methodology cannot provide any "silver bullets" for inducing sustainability transitions, it is flexible enough to identify an appropriate abstraction level for analyzing and designing transition governance processes. The methodology developed in this doctoral research also provides several contributions for the development of participatory modeling methods in transition research. Thus, the participatory method supports an integrated analysis of barriers and drivers of sustainability innovations, and allows application in practice and education. The concepts and methods developed in this research project allow for reflection on transition governance processes from a systemic viewpoint. Experiences in the case studies underline the applicability of the concepts and methods developed for the analysis of case-specific transition governance processes. Despite substantial differences in the geographic location, culture and topics addressed, all case studies include promising sustainability innovations and the engagement of multiple actors in their implementation. The diversity and multitude of initiatives in the case study regions provides an optimistic outlook on future opportunities for large-scale sustainability transitions.
Climate change is a transformation challenge. It requires the transformation of a patchwork of independent socio-technical systems. These complex systems have their own specific challenges and path dependencies. Lukas Hermwille introduces a perspective on socio-technical complexity to the study of global climate governance and asks what governance arrangements on the international level, in particular the United Nations Framework Convention of Climate Change (UNFCCC) and its Paris Agreement, can offer to facilitate and foster the required transformational change. His work shows the importance of the discursive power of global climate governance, shifting the expectations and visions of the future of key actors and, as a corollary, changing their investment decisions of today towards a more sustainable future.
How is it possible to increase homeowners' insulation activity? Answering this question is key to successful policies regarding energy-efficient buildings worldwide. In Germany, doubling today's insulation rate of about 1% is an important element for reaching the government's target of an 80% reduction in energy demand in the building sector by 2050.
This thesis uses an agent-based model analysis to improve the understanding of homeowners' insulation activity and to explore new approaches aiming at its increase in Germany. Two agent-based models were developed and utilized. The first model was developed mainly based on insights derived from a structured literature review. The second emerged from the previous one, incorporating the results of an online survey conducted among 275 homeowners.
The results indicate that homeowners' economic means have little influence on their decision to install insulation. Instead, their insulation decision-making is mostly affected by situational factors and their attitudes towards insulation. Situational factors, such as the condition of the building, are important because they initiate homeowners' individual decision-making processes on insulation. The simulation results show that improving homeowners’ attitudes about insulation by providing information has a comparatively low potential for increasing their insulation activity. Out of the policy options this thesis explored, the introduction of an obligation to insulate the walls within one year after change of house ownership was found to have the greatest impact on homeowners' insulation activity.
Institutional theory scholars have been successful at explaining how organizations strive to attain a stable framework for their patterns of interaction, but have, until recently, struggled to account for institutional renewal. Institutional change happens when new practices become accepted and interactions between organizations carry new meanings. This historical study of the international climate change mitigation regime (1992 - 1997) provides insight into the dynamic processes that take place during the early stage of institutionalization. More specifically, the thesis examines the following issues: How do power differentials shift during institutional change? How do institutions operate in the environmental field? How can entrepreneurs influence their institutional setting? How do certain groups of organizations bring about or support particular sets of ideological frames? The empirical study analyses the policy innovation of the Clean Development Mechanism, proposed in the Kyoto Protocol to the United Nations Framework Convention on Climate Change. The thesis confirms that the proposed governance of climate-friendly technology transfer constitutes institutional change and the emergence of a proto-institution. It furthermore analyzes how the organizational actors brought about this innovation and how the change in meaning was introduced into the public sphere. The qualitative research methods that were employed include observation at climate negotiations, focus groups of climate policy professionals, semi-structured interviews of policy makers, and content analysis of archival data.
Achieving sustainability has become one of the fundamental goals of many urban transportation systems in the past two decades. The emerging concept of sustainability has developed enormous interests among researchers and practitioners to develop a sustainable transport system. While many have focused on developing an appropriate definition of a sustainable transport by measures and indicators of sustainability to assess if a transport system is moving towards or away from sustainability, many others have put forward different strategies to make a transport system sustainable. Defining sustainable transport and identifying indicators are important to make this concept more correct, focused, and measurable.
This study tries to measure and monitories urban transportation sustainability from viewpoint of anÿurban planner. The question comes out from the relation between urban transportation sustainability and usage of public transportation. How these two facts link to each other? Are there any logical relations between usage of public transportation and sustainable development? How we can define specific indicator for measuring sustainability of transportation or on the other words, how can we standardized indicator to measure and monitor the urban sustainable transportation?
For response, exceeding questions two cities are selected which have a similarity and differences in structure and data sets. Our approach is to draw upon a raft of suitable analytical techniques to find out the approach base for comparison of structure between different cities, and then to apply the examples to examine the degree to which specified policy targets might be met in the future. The analytical framework includes Descriptive statistics, correlation and Regression analysis, and application of sustainable transportation indicator for case studies distributions.
The techniques proposed to provide a starting point for that dialogue toward more appropriate policies and their monitoring. It can be concluded that the new approach of sustainable transportation indicator for measuring sustainability of transportation is highly correlated with selected variables, which indicates that the new indicator has meaningful applicability to be used as indicator for transportation certificate system. This methods can be used for measuring, monitoring, and evaluating the sustainability of urban transportation for different areas and used the results as a standardize indicator for transportation certificate system for comparing and ranking the transportation sustainability of different cities. In addition, the result of this study can be used as for monitoring and assessment of plan for (SUMP) Sustainable urban mobility planning.
This thesis investigates the relationship between public and private sector efforts to optimise energy efficiency finance initiatives in an emerging country context, using Thailand as a case study. Demand-side energy efficiency measures could significantly reduce pressures on energy systems in emerging economies in Southeast Asia while at the same time reducing greenhouse gas emissions. Rapidly increasing energy needs, combined with dependence on fossil fuel imports have put energy systems in the region under pressure. Due to high urbanisation growth rates, and comparatively inefficient industries, demand-side energy efficiency measures could be part of the solution. The lack of external energy efficiency finance for industry and building owners is a major barrier, but reports and country examples contain mixed messages about how to best overcome this challenge. The dominant discourse around energy efficiency finance originates from international organisations who advocate for the public sector to focus all efforts on maximising private sector investments. However, developed country experience and some emerging country examples, suggest that the problem is more complex. Therefore, this thesis focuses on how to optimise energy efficiency finance. Thailand serves as a case study due to the range of energy efficiency initiatives designed and implemented in that country since the early 1990s. Transition studies and Multi-Level Perspective, were chosen as the theoretical framework and heuristic tool for the analysis. Qualitative data in the form of interviews with forty-eight experts from government, the private sector and academia form the core of this research. The research found that in Thailand, after more than 10 years of public sector support for energy efficiency finance initiatives, success in the private sector has been limited. Challenges identified include: (1) a lack of de-risking measures (2) renewable energy projects receiving most funding; (3) lack of guidance from the Central Bank of Thailand and (4) missing cross-coordination with relevant ministries to create additional demand for energy efficiency finance services. Suggestions for next steps are provided. The main finding from this research is that EEF in an emerging country context will never be transitioned 100% to the private sector, but will be reliant on long-term consistent support from the public sector. Policy makers and international organisations must therefore carefully evaluate the existing framework conditions before choosing which energy efficiency finance initiatives to support. The Multi-Level Perspective analytical framework could provide such an analytical tool to further unleash the energy efficiency potential in Southeast Asia.
