In this brochure, WISIONS focuses on the significance of innovative strategies in the field of sustainable tourism. WISIONS presents projects from Tanzania, Germany, Ecuador, Switzerland and Ghana 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, but social aspects such as the inclusion of local population were also of relevance. The assessment of the projects also included the consideration of regional factors acknowledging different needs and potentials.
Gerhard Berz leitete lange Jahre die GeoRisikoForschung der Mü̈nchener Rück. Die Gründung seines Kompetenzzentrums ergab sich aus den Schutzzielen und dem Selbstverständnis des Unternehmens: Risiken müssen sachlich begründet eingeschätzt und existenzbedrohende Risiken ausgeschlossen werden können. Und da das dazu notwendige Wissen außen nicht verfügbar ist, muß es im eigenen Haus verfügbar gemacht werden. Mit der Einrichtung eines Forschungsinstituts seitens einer privatrechtlichen "Gesellschaft" ist eine überzeugende und modellhafte Antwort auf die Frage gegeben, welches Wissen zu welchem Zweck generiert, aufbereitet und - auch öffentlich, an Kunden - verbreitet werden muß, um Schäden von der Gesellschaft abzuwenden. Die Ausrichtung der GeoRisikoForschung der Münchener Rück als ein Modell für die internationale Klima- und Erdsystemwissenschaft im Verhältnis zu der sie tragenden Gesellschaft?
Impacts of energy use on demand for freight transport : past development and future perspectives
(2005)
Under the framework of the UN framework convention on climate change (UNFCCC) and its Kyoto Protocol the targets and strategies for the second and third commitment period ("post-2012") have to be discussed and set in the near future. Regarding the substantial emission reductions that have to be shouldered by the industrialized nations over the next two decades it is evident that all available potentials to mitigate greenhouse gas (GHG) emissions have to be harnessed and that energy efficiency has to play a key role.
To substantiate this we developed a comprehensive scenario analysis of the EU 25s energy system and other greenhouse gas emissions until 2020. Our analysis shows which key potentials to mitigate greenhouse gas emissions are available, by which policies and measures they are attainable
and which will be benefits of greenhouse gas mitigation measures.
By this analysis we show the mayor role of energy efficiency in all sectors and all member states. We demonstrate that a reduction of EU 25 greenhouse gas emissions by more than 30 % by 2020 is feasible, reasonable and - to a large extent - cost effective. We also develop a comprehensive policy package necessary to achieve ambitious Post-Kyoto targets.
The scenario analysis results in a clear identification of the needed strategies, policies and measures and especially the relevance of energy efficiency to achieve the necessary ambitious greenhouse gas reduction targets. It also clearly shows the costs and the benefits of such a policy compared to a business as usual case.

In this brochure, WISIONS focuses on the significance of innovative strategies in the field of sustainable transport. WISIONS presents a number of projects from around the globe 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 selection of the projects was energy and resource efficiency, but social aspects such as the inclusion of local population were also of relevance. The assessment of the projects also included the consideration of regional factors acknowledging different needs and potentials.
Based on different current long-term energy scenarios the paper discusses the future perspectives of hydrogen in the German energy system as a representative example for the development of sustainable energy systems. The scenario analysis offers varying outlines of the future energy system that determine the possible role of hydrogen. The paper discusses the possibilities of expanding the share of renewable energy and the resulting prospects for establishing clean hydrogen production from renewable energy sources. Emphasis is given to the questions of an ecologically efficient allocation of limited renewable energy resources that can only be assessed from asystems analysis perspective. Findings from recent studies for Germany reveal a strong competition between the direct input into the electricity system and an indirect use as fuel in the transport sector. Moreover, the analysis underlines the paramount importance of reducing energy demand as the inevitable prerequisite for any renewable energy system.
Mit Inkrafttreten des Kyoto-Protokolls am 16.2.2005 gelten für Deutschland und die meisten anderen Industrieländer völkerrechtlich bindende Minderungsziele für die 6 im Kyoto-Protokoll erfassten Treibhausgase. Damit erlangt eine durchaus kontrovers diskutierte Klimaschutzstrategie, die auf eine stärkere Umstellung der Energienutzung von Öl und Kohle auf mehr Erdgas setzt, zusätzlich an Bedeutung. Der nachfolgende Beitrag setzt sich mit der Klimabilanz des Erdgases unter Berücksichtigung der gesamten Prozesskette auseinander. Insbesondere werden neue Messergebnisse aus Russland dargestellt (Wuppertal Institut 2004), die zeigen, dass die dem Export von russischem Erdgas nach Deutschland zuzuordnenden indirekten Emissionen nur etwa ein Viertel der bei der Erdgasverbrennung entstehenden direkten Emissionen betragen. Damit bleibt Erdgas auch unter Berücksichtigung der indirekten Emissionen in Russland der fossile Energieträger mit den mit Abstand geringsten Treibhausgasemissionen.
Using natural gas for fuel releases less carbon dioxide per unit of energy produced than burning oil or coal, but its production and transport are accompanied by emissions of methane, which is a much more potent greenhouse gas than carbon dioxide in the short term. This calls into question whether climate forcing could be reduced by switching from coal and oil to natural gas. We have made measurements in Russia along the world's largest gas-transport system and find that methane leakage is in the region of 1.4%, which is considerably less than expected and comparable to that from systems in the United States. Our calculations indicate that using natural gas in preference to other fossil fuels could be useful in the short term for mitigating climate change.
