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.

Within one decade a fundamental choice will have to be made: Should the energy system follow the historical trends of risky and unsustainable energy use patterns? Or should it take the course towards sustainable development and climate protection, giving top priority to energy efficiency and to a broad mix of renewable energies? Both roads are technically feasible. "Back-casting"-scenarios could help to answer the question, what technological options are available for climate protection and how societal goals can be achieved in a cost-effective way. Lessons learned from world energy scenarios and possible implementation options will be discussed. A case study of the German Parliament ́s Enquete Commission on Sustainable Energy Systems will be taken as illustration. The analysis shows that sustainable energy systems can be financed and that economic growth can be decoupled from absolute levels of non-renewable energy consumption by stepping up energy productivity.
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.
