Beschreibung: Oil crisis, water conflicts, declining food security - we hear one report after another about resource scarcity - while with growing populations and huge poverty, nations are demanding their right to development. In the age of globalisation this right cannot be disputed, yet the planet is already exhibiting signs of acute environmental stress. Indians want more roads and Chinese more oil: the struggle over nature will partly shape the crises of the twenty-first century. Clashes over resources, both major and minor, are often the unseen factor behind chaos and violence and it is vital to start thinking about how the distribution of resources can be made more just. This book provides an account of what is involved in the resource conflicts of today and tomorrow. It puts forward perspectives for resource justice and outlines a global economic and environmental policy equally committed to nature and to humanity.

Beschreibung: In this study, the relevance of psychological variables as predictors of the ecological impact of mobility behavior was investigated in relation to infrastructural and sociodemographic variables. The database consisted of a survey of 1991 inhabitants of three large German cities. In standardized interviews attitudinal factors based on the theory of planned behavior, further mobility-related attitude dimensions, sociodemographic and infrastructural characteristics as well as mobility behavior were measured. Based on the behavior measurement the ecological impact of mobility behavior was individually assessed for all participants of the study. In a regression analysis with ecological impact as dependent variable, sociodemographic and psychological variables were the strongest predictors, whereas infrastructural variables were of minor relevance. This result puts findings of other environmental studies into question which indicate that psychological variables only influence intent-oriented behavior, whereas impact-oriented behavior is mainly determined by sociodemographic and household variables. The design of effective intervention programs to reduce the ecological impact of mobility behavior requires knowledge about the determinants of mobility-related ecological impact, which are primarily the use of private motorized modes and the traveled distances. Separate regression analyses for these two variables provided detailed information about starting points to reduce the ecological impact of mobility behavior.

Beschreibung: Scenarios for the future of renewable energy through 2050 are reviewed to explore how much renewable energy is considered possible or desirable and to inform policymaking. Existing policy targets for 2010 and 2020 are also reviewed for comparison. Common indicators are shares of primary energy, electricity, heat, and transport fuels from renewables. Global, Europe-wide, and country-specific scenarios show 10% to 50% shares of primary energy from renewables by 2050. By 2020, many targets and scenarios show 20% to 35% share of electricity from renewables, increasing to the range 50% to 80% by 2050 under the highest scenarios. Carbon-constrained scenarios for stabilization of emissions or atmospheric concentration depict trade-offs between renewables, nuclear power, and carbon capture and storage (CCS) from coal, most with high energy efficiency. Scenario outcomes differ depending on degree of future policy action, fuel prices, carbon prices, technology cost reductions, and aggregate energy demand, with resource constraints mainly for biomass and biofuels.

Beschreibung: The material stocks in the anthroposphere are growing faster than ever due to urbanization and growing per capita use. Owing to the growing potential insecurity of raw material supply the evaluation of resources gains increasing attention. Despite growing utilization of anthropogenic deposits, ‘urban mining’ has not yet sufficiently been supported by specific exploration methods. An exploration method for anthropogenic deposits is proposed and described by application to the copper stocks of Switzerland. The method combines material flow analysis with a bottom‐up analysis of material stocks. The stock composition and temporal characteristics are analysed by surveys and literature analysis. The stock amounts to 269±31 kg capita -1 for the year 2000. The retrospective data are used as parameters to construct a dynamic stock model, which is calibrated by historical trade statistics. The potential for drafting scenarios is discussed. The stock situation in Switzerland is reviewed and compared with that of other regions.

Beschreibung: Stabilizing the concentration of greenhouse gases (GHGs) in the atmosphere at levels compatible with sustainable development is the objective of the United Nations Framework Convention on Climate Change (UNFCCC) and an imperative for the global community. This is a daunting task, and its magnitude and costs are debated among scientists as well as policy-makers [Stern, 2006]. While most GHGs in the past have been emitted by developed countries and they are called upon to reduce their emissions and take responsibility for past mistakes, the contribution of developing countries in the future will reach similar magnitudes and is equally threatening for life on this planet. While developing countries have no commitments under the UNFCCC, they can still contribute voluntarily to climate change mitigation. The Global Environment Facility (GEF), as the financial mechanism of the UNFCCC and the leading multilateral entity promoting energy efficiency and renewable energy in developing countries and countries in transition, needs to provide significant support to these countries with respect to reaching a path of sustainable energy supply and sustainable economic and social development. Since 1992, the GEF has provided around US$ 2 billion in grants to support projects in the climate change focal area, leveraging over US$ 10 billion in total investments. Most of these funds have been spent on climate change mitigation projects. The GEF's mandate with respect to mitigation is to develop, expand, and transform markets for energy and mobility in developing countries, enabling them to grow toward and efficiently operate on a less carbon-intensive path. In doing so, the GEF applies the incremental cost principle and is restricted in the selection of technologies by a number of factors. Developing markets for sustainable energy technologies and sustainable framework conditions is a long-term effort, and it is hard to understand how effective the GEF is or can be in fulfilling this mission. This paper discusses the magnitude of the challenge, and demonstrates that this challenge is too big for the GEF's limited funds, and provides some suggestions for the GEF's programming for maximizing its impact on global GHG emissions by seeking out the most rewarding opportunities and maximizing replication of successful project examples by effective outreach and knowledge management.

Beschreibung: The enhanced use of biomass for the production of energy, fuels, and materials is one of the key strategies towards sustainable production and consumption. Various life cycle assessment (LCA) studies demonstrate the great potential of bio-based products to reduce both the consumption of non-renewable energy resources and greenhouse gas emissions. However, the production of biomass requires agricultural land and is often associated with adverse environmental effects such as eutrophication of surface and ground water. Decision making in favor of or against bio-based and conventional fossil product alternatives therefore often requires weighing of environmental impacts. In this article, we apply distance-to-target weighing methodology to aggregate LCA results obtained in four different environmental impact categories (i.e., non-renewable energy consumption, global warming potential, eutrophication potential, and acidification potential) to one environmental index. We include 45 bio- and fossil-based product pairs in our analysis, which we conduct for Germany. The resulting environmental indices for all product pairs analyzed range from -19.7 to +0.2 with negative values indicating overall environmental benefits of bio-based products. Except for three options of packaging materials made from wheat and cornstarch, all bio-based products (including energy, fuels, and materials) score better than their fossil counterparts. Comparing the median values for the three options of biomass utilization reveals that bio-energy (-1.2) and bio-materials (-1.0) offer significantly higher environmental benefits than bio-fuels (-0.3). The results of this study reflect, however, subjective value judgments due to the weighing methodology applied. Given the uncertainties and controversies associated not only with distance-to-target methodologies in particular but also with weighing approaches in general, the authors strongly recommend using weighing for decision finding only as a supplementary tool separately from standardized LCA methodology.

Beschreibung: Approaches to address unsustainable ways of societal development constantly proliferate, but total consumption of resources and aggregate environmental impacts continue rising. This could partially be explained by weak attempts to develop comprehensive sustainability strategies that address the entire life cycle of products and especially resource extraction and use phases. This paper seeks to explore to what extent these life cycle stages and associated impacts are taken into account when various actors employ life cycle thinking and how these concerns can be better attended to in policy-making, business strategies and lifestyle choices. To accomplish this, we evaluate the efforts of the main stakeholders in reaching sustainable consumption and sustainable resource management, and impediments to further progress, and study whether and how deficits in these phases coincide and can potentially contribute to more holistic practical realization of life cycle thinking. We demonstrate that new approaches are needed to be able to tackle the international dimension of production and consumption.

Beschreibung: For the option of “carbon capture and storage”, an integrated assessment in the form of a life cycle analysis and a cost assessment combined with a systematic comparison with renewable energies regarding future conditions in the power plant market for the situation in Germany is done. The calculations along the whole process chain show that CCS technologies emit per kWh more than generally assumed in clean-coal concepts (total CO2 reduction by 72-90% and total greenhouse gas reduction by 65-79%) and considerable more if compared with renewable electricity. Nevertheless, CCS could lead to a significant absolute reduction of GHG-emissions within the electricity supply system. Furthermore, depending on the growth rates and the market development, renewables could develop faster and could be in the long term cheaper than CCS based plants. Especially, in Germany, CCS as a climate protection option is phasing a specific problem as a huge amount of fossil power plant has to be substituted in the next 15 years where CCS technologies might be not yet available. For a considerable contribution of CCS to climate protection, the energy structure in Germany requires the integration of capture ready plants into the current renewal programs. If CCS retrofit technologies could be applied at least from 2020, this would strongly decrease the expected CO2 emissions and would give a chance to reach the climate protection goal of minus 80% including the renewed fossil-fired power plants.

Beschreibung: The use of materials and the generation of waste are linked to economic activities and in many projections these are assumed to be a constant ratio of the economic activities. This may be the case considering detailed economic activities and unchanged technology. However, the assumption of constant coefficients is questionable when linking material use and waste generation to aggregated economic activities. Therefore, in this paper, econometrics is used to test the assumption of constant waste coefficients empirically. The analyses show that an assumption of constant waste coefficients is not supported, generally, and amodel allowing for trendwise changing coefficients is developed and used for projections of waste and material flows in 25 European countries.

Beschreibung: The "South-North Dialogue" Proposal, developed by researchers from developing and industrialised countries, outlined equitable approaches to mitigation. These approaches were based on the criteria of responsibility, capability and potential to mitigate, and include deep cuts in industrialised (Annex I) countries and differentiated mitigation commitments for developing countries. This paper quantitatively analyses the implications of the proposal for countries' emissions and costs. The analysis focuses on a "political willingness" scenario and four stabilisation scenarios. The analysis shows that stringent stabilisation targets imply that many developing countries would have to take on quantitative mitigation obligations by 2030, even when the Annex I countries take on ambitious mitigation commitments far beyond the Kyoto obligations. The "political willingness scenario" will probably not suffice to limit a warming of the Earth's atmosphere to below 2 °C.

Beschreibung: This book considers corporate governance of sustainability from a co-evolutionary perspective. It explores the linkages between pro-active approaches at the corporate level, market-based incentives and environmental networks involving various actors. Relevant theory on corporate governance, competition, market failures and regulatory tools is also examined. The authors go on to present an assessment methodology suitable for empirical network analysis at the meso-level, and demonstrate its application using eight case studies. Based on these research results, Raimund Bleischwitz and his team draw important conclusions regarding policy analysis, sustainability assessment and the actors involved.

Beschreibung: A number of "roadmapping" activities are being carried out internationally with the aim of planning and facilitating transitions to hydrogen energy systems. However, there is an evident discrepancy between the treatment of quantitative and qualitative information in the majority of roadmapping efforts. Whilst quantitative information is frequently analysed in numerical and computational models, conversely qualitative information tends to be incorporated on a significantly more ad hoc basis. Previous attempts at incorporating qualitative considerations have not usually been systematised. In this paper we present a methodology aimed at increasing the rigour with which qualitative information is treated in hydrogen roadmapping activities. The key changes and actor mapping (KCAM) methodology was developed as the primary qualitative component of the European Hydrogen Energy Roadmap project "HyWays". KCAM, developed from a well known general systems development model, constitutes a means of qualitatively analysing variable hydrogen supply chains that is structured, systematic and flexible.

Beschreibung: 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.

Beschreibung: The idea of removing carbon dioxide from flue gas and industrial gas flows and putting it into suitable long-term storage sites is referred to as Carbon Capture and Storage (CCS). This publication provides a close look at this new line of technologies, describing its current status and outlining the prospects for development. The approach is both diagnostic and analytical, identifying the questions a technology assessment poses and showing the steps that need to be taken to implement CCS. CCS is currently moving to the centre of climate policy discussion. Nonetheless this line of technologies is still the subject of controversial discussion. On the one hand there is a clear hope that these technologies will open up opportunities to use fossil fuels without harming the climate and thus make it possible to continue using oil, natural gas and above all coal even under a stricter climate regime. Accordingly, numerous R&D projects have been initiated all over the world, and various demonstration projects are at the planning or implementation stage. On the other hand, CCS (especially the storage part) has given rise to considerable scepticism from an ecological point of view.

Beschreibung: 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.

Beschreibung: About 2 % of the overall electricity consumption of the EU is caused by circulators in single or double family homes and flats. A new technology of pumps with electronically commutated (EC) motor pumps is available now; it is one possible way to achieve a reduction in circulator annual electricity use by 60 % or more. The project's objective is a market transformation towards this new very energy-efficient pump technologies - Energy+ pumps - for circulators in heating systems, both stand alone and integrated in boilers. Only few manufacturers have so far introduced the new pump technology to the market for single or double family homes and flats. To bring more products to the market from all major manufacturers, the project will adapt and apply the technology procurement methodology as it was very successfully tested in the European Energy+ project on energy-efficient cold appliances. Large buyers will be aggregated, to activate the pump and boiler manufacturers. Sales and training materials and a sizing spreadsheet software for installation contractors will be developed and applied. A competition both for energy-efficient products and marketing campaigns will be organised and the information on the Energy+ pumps will be disseminated widely through website, newsletter, media, and fairs. This paper gives a short overview of this project and presents the results of the first project phases: a European wide market study on circulators and heating systems, and the first Energy+ lists for circulators, buyers and supporters.

Beschreibung: National welfare is no longer an effective frame of reference for enlightened foreign policy. Policy consideration must encompass the common welfare of a world society. Environmental and resource crises are inextricably tied to security and justice. Sixty years after the founding of the United Nations there should be a new effort to establish a genuinely sustainable global order - a "San Francisco 2.0".

Beschreibung: In this brochure, WISIONS focuses on how sustainable energy use can support poverty reduction. WISIONS presents projects from Namibia, Brazil, the Philippines and India 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 with social aspects being of high additional relevance. The assessment of the projects also included the consideration of regional factors acknowledging different needs and potentials.

Beschreibung: The Russian natural gas industry is the world's largest producer and transporter of natural gas. This paper aims to characterize the methane emissions from Russian natural gas transmission operations, to explain projects to reduce these emissions, and to characterize the role of emissions reduction within the context of current GHG policy. It draws on the most recent independent measurements at all parts of the Russian long distance transport system made by the Wuppertal Institute in 2003 and combines these results with the findings from the US Natural Gas STAR Program on GHG mitigation options and economics. With this background the paper concludes that the methane emissions from the Russian natural gas long distance network are approximately 0.6% of the natural gas delivered. Mitigating these emissions can create new revenue streams for the operator in the form of reduced costs, increased gas throughput and sales, and earned carbon credits. Specific emissions sources that have cost-effective mitigation solutions are also opportunities for outside investment for the Joint Implementation Kyoto Protocol flexibility mechanism or other carbon markets.

Beschreibung: The United Nations climate change conference in Nairobi came at the end of a year where public awareness of climate change had reached unprecedented heights. Nonetheless, the conference proceeded with its usual diplomatic ritual, apparently unaffected by time pressure. While it did see some progress on important issues for developing countries such as the Adaptation Fund, the Nairobi Work Programme on Impacts, Vulnerability, and Adaptation to Climate Change, and the Clean Development Mechanism (CDM), on questions regarding the future of the regime it proved to be at best a confidence-building session that served to hear further views. More serious work on the future of the regime must therefore be expected of the next Conferences of the Parties. This article by Wolfgang Sterk, Hermann E. Ott, Rie Watanabe and Bettina Wittneben summarises the results of the conference.
