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.
The analysis of different global energy scenarios in part I of the report confirms that the exploitation of energy efficiency potentials and the use of renewable energies play a key role in reaching global CO2 reduction targets. An assessment on the basis of a broad literature research in part II shows that the technical potentials of renewable energy technologies are a multiple of today's global final energy consumption. The analysis of cost estimates for renewable electricity generation technologies and even long term cost projections across the key studies in part III demonstrates that assumptions are in reasonable agreement. In part IV it is shown that by implementing technical potentials for energy efficiency improvements in demand and supply sectors by 2050 can be limited to 48% of primary energy supply in IEA's "Energy Technology Perspectives" baseline scenario. It was found that a large potential for cost-effective measures exists, equivalent to around 55-60% of energy savings of all included efficiency measures (part V). The results of the analysis on behavioural changes in part VI show that behavioural dimensions are not sufficiently included in energy scenarios. Accordingly major research challenges are revealed.

This paper presents the strategy for a large EU-funded Integrated Project: EXIOPOL ("A New Environmental Accounting Framework Using Externality Data and Input-Output Tools for Policy Analysis"), with special attention for its part in environmentally extended (EE) input-output (IO) analysis. The project has three principal objectives: (a) to synthesize and further develop estimates of the external costs of key environmental impacts for Europe; (b) to develop an EE IO framework for the EU-27 in aglobal context, including as many of these estimates as possible, to allow for the estimation of environmental impacts (expressed as LCA themes, material requirement indicators, ecological footprints or external costs) of the activities of different economic sectors, final consumption activities and resource consumption; (c) to apply the results of the work to external costs and EE I-O for illustrative policy questions.
This paper argues that Entertainment-Education (E-E) is a striking communication strategy for reaching middle and lower socio-economic classes with climate-friendly lifestyle messages. On the international level (e.g. in the US and the Netherlands) E-E approaches are being theoretically grounded, whereas in Germany they are not yet. Therefore further theoretical discussion and mapping of E-E approaches is central for future research. As a first step towards providing further theoretical foundations for E-E in the field of sustainability, the authors suggest a threefold mapping of E-E approaches. The threefold mapping of E-E approaches for communicating climate-friendly lifestyles to middle and lower class consumers is based on recent results from academic research and practical developments on the media market. The commonalities among the three is that they all promote pro-sustainability messages in an affective-orientated rather than cognitive-orientated, factual manner. Differences can be found in: the sender of the sustainability message, the targeted consumer groups and the media approach in use. Based on this, the paper draws the conclusion that two new paths for further research activities in the field of Entertainment-Education can be proposed: (1) Improving the existing approaches in practice by using theoretical foundation from the E-E field. This comprises at its core (A) to do formative, process and summative effect research on the messages and (B) to use E-E theory from the field of social psychology, sociology and communication science for further improvement and (2) Generating new E-E theories by analyzing the existing practical approaches in the media to communicate climate change.
