It is now widely recognized that effective communication and demand-side policies for alternative energy require sound knowledge of preferences and determinants of demand of the public and consumers. To date, public attitudes towards new transport technologies have been studied under very different conceptual frameworks. This paper gives an overview of the various conceptual frameworks and methodologies used, where four main approaches can be distinguished: general attitudinal surveys, risk perception studies, non-market economic valuation studies, and other approaches such as those based on semiotic theory. We then review the findings of the recent literature on acceptance, attitudes and preferences for hydrogen and fuelcell end-use technologies, focusing on vehicles. These studies are then contrasted with related research into alternative fuel vehicles. The paper finally discusses the main trends in research and avenues for further work in this field. We recommend, among other things, the use of approaches that build knowledge and familiarity with the technology prior to the exploration of attitudes, and the set up of studies that take a whole-systems perspective of hydrogen technologies and that look at hydrogen in the context of other competing clean technologies.
Taking public transport by bus in the Chinese Metropolis Hefei as an example, the report analyses the practicability of standardised baselines as possible instruments for climate protection funding. The development of standardised baselines for the transport sector has been pushed since the nineties in order to better assess emission reductions of CDM projects. Further aims of standardising are a clinical comparison and a precise forecasting. For all projects of a defined sector, class, size or a given geographical origin it is possible to develop standardised baselines in the sense of reference value for emissions. The report was produced in the context of the initiative "Partnership on Sustainable Low Carbon Transport" (SLoCaT), commissioned by the Asian Development Bank. It complements the study "Applicability of Post 2012 Climate Instruments to the Transport Sector (SITS)", that analyses the impacts of climate protection funding mechanisms like the Clean Development Mechanism (CDM) in the transport sector of metropolises in emerging nations and gives recommendations for the further development of financing mechanisms.
This paper undertakes a step to explaining the international economics of resource productivity. It argues that natural resources are back on the agenda for four reasons: the demand on world markets continues to increase, the environmental constraints to using resources are relevant throughout their whole life cycle, the access to critical metals could become a barrier to the low carbon economy, and uneven patterns of use will probably become a source of resource conflicts. Thus, the issue is also of relevance for the transition to a low carbon economy. "Material Flow Analysis" is introduced as a tool to measure the use of natural resources within economies and internationally; such measurement methodology now is being harmonized under OECD auspices. For these reasons, the paper argues that resource productivity - that is the efficiency of using natural resources to produce goods and services in the economy - will become one of the key determinants of economic success and human well-being. An empirical chapter gives evidence on time series of resource productivity increases across a number of economies. Introducing the notion of "material flow innovation", the paper also discusses the innovation dynamics and issues of competitiveness. However, as the paper concludes, market barriers make a case for effective resource policies that should provide incentives for knowledge generation and get the prices right.
Eine nachhaltige Entwicklung und die dafür notwendige Steigerung der Ressourceneffizienz stellt für Organisationen und deren Akteure eine Herausforderung dar, die neben technologischer vor allem auch sozialer und organisatorischer Innovationen bedarf. Strategische Allianzen gehören zu den wichtigsten Nachhaltigkeits-orientierten Innovationen und ermöglichen als bereichsübergreifende Kooperationen wechselseitige Lernprozesse zwischen Wirtschaftsunternehmen, Staat und Zivilgesellschaft.
In dem Projekt wurde untersucht, welche Anforderungen an Unternehmen, ihre Managementsysteme, deren Personal-, Organisations- und Kompetenzentwicklungen sowie die Ausgestaltung der Arbeitsplätze gestellt werden, um nachhaltigkeitsorientierte Netzwerke und Allianzen erfolgreich und langfristig zu etablieren und ihren Wirkungsbereich auszubauen. Neben der systemübergreifenden Analyse stand die Entwicklung von praxisgerechten Lösungskonzepten und Instrumenten im Vordergrund.
Economic performance of a country is generally being measured through GDP (Gross Domestic Product), a variable that has also become the de facto universal metric for "standards of living". However, GDP does not properly account for social and environmental costs and benefits. It is also difficult to achieve sustainable decision-making aiming at sustainable progress and well-being if welfare is being considered from a purely financial point of view. The study highlights the benefits and some of the shortcomings of GDP. It serves as a helpful and practicable instrument for monetary and fiscal policies. The real problem presumably is that GDP growth is too often confused with (sustainable) welfare growth in people's minds. While there certainly is a correlation between the two, this study shows that this is a highly conditional correlation, void of substantial causality for GDP levels observable in the European Union. In order to be able to assess people's well-being and general sustainable development in the sense of sustainability, an alternative instrument going beyond GDP is necessary. Using so called SWOT analyses, several alternative progress indicators have been assessed in the context of this study. On the one hand it was analysed how far ecological and social factors can be integrated in the GDP measurements. Thereby difficulties arose then trying to monetise these factors. As a further possibility indicators were analysed which are to replace GDP as a whole. The category supplementing GDP seems to be the most realistic and acceptable option for going beyond GDP. Within this approach, GDP is being complemented with additional environmental and/or social information. In order to make this kind of solution feasible the study claims the establishment of an overarching and transparent indicator system for improving economic decision-making in support of sustainable development.
Die Ökodesign-Richtlinie (Richtlinie 2009/125/EG des Europäischen Parlaments und des Rates vom 21. Oktober 2009 zur Schaffung eines Rahmens für die Festlegung von Anforderungen an die umweltgerechte Gestaltung energieverbrauchsrelevanter Produkte) trat im Jahre 2005 in Kraft und wurde im Jahr 2009 revidiert und erweitert. Die Richtlinie zielt auf Verbesserungen des Designs energieverbrauchsrelevanter Produkte mit dem Ziel einer Reduktion der Umweltbelastungen unter Berücksichtigung aller Phasen des Produktlebenszyklusses. So sind bereits im Rahmen dieser Richtlinie beispielsweise Mindestenergieeffizienzanforderungen für bestimmte, auf dem europäischen Markt angebotene Geräte festgelegt worden, die von den Geräteherstellern und -importeuren eingehalten werden müssen.
The physical dimension of international trade. Part 1: Direct global flows between 1962 and 2005
(2010)
The physical dimension of international trade is attaining increased importance. This article describes a method to calculate complete physical trade flows for all countries which report their trade to the UN. The method is based on the UN Comtrade database and it was used to calculate world-wide physical trade flows for all reporting countries in nine selected years between 1962 and 2005. The results show increasing global trade with global direct material trade flows reaching about 10 billion tonnes in 2005, corresponding to a physical trade volume of about 20 billion tonnes (adding both total imports and total exports). The share from European countries is declining, mainly in favour of Asian countries. The dominant traded commodity in physical units was fossil fuels, mainly oil. Physical trade balances were used to identify the dominant resource suppliers and demanders. Australia was the principal resource supplier over the period with a diverse material export structure. It was followed by mainly oil-exporting countries with varying volumes. As regards to regions, Latin America, south-east Asian islands and central Asia were big resource exporters, mostly with increasing absolute amounts of net exports. The largest net importers were Japan, the United States and single European countries. Emerging countries like the "Asian Tigers" with major industrial productive sectors are growing net importers, some of them to an even higher degree than European countries. Altogether, with the major exception of Australia and Canada, industrialized countries are net importers and developing countries and transition countries are net exporters, but there are important differences within these groups.
Ein institutionelles Reformprogramm zur Förderung transdisziplinärer Nachhaltigkeitsforschung
(2010)
Die deutsche Politik orientiert sich in weiten Teilen an Nachhaltigkeit. Da erstaunt es, dass transdisziplinäre Nachhaltigkeitsforschung im Land kaum etabliert ist. Ein institutionelles Reformprogramm, das die besonderen Strukturbedingungen des deutschen Wissenschaftssystems berücksichtigt, vermag dies zu ändern.
The Gulf countries are largely dependent on exporting oil and natural gas for their national budgets. They mainly use domestic fossil fuels for their domestic energy supply. In spite of favorable geographic conditions, especially for solar energy, renewable energies are still a niche application. Abu Dhabi, besides Dubai, the most important emirate in the United Arab Emirates (UAE), has now started a process of "transforming oil wealth into renewable energy leadership", and has set the long-term goal of a "transition from a 20th Century, carbon-based economy into a 21st Century sustainable economy." This article is a case study about "Masdar City", a planned carbon-neutral town in Abu Dhabi. The article describes the key characteristics of Masdar City, analyses the drivers behind the project, identifies the main actors for its implementation, and seeks obstacles to creation and development as well as the policy behind Masdar City. Finally, a first judgment of possible diffusion effects of the project is done.
