Transboundary river basin management, in itself a complex subject due to the variety of countries and stakeholders involved, is facing increasing challenges due to new social, economic and climate-change drivers. In this article, Tom Raadgever, Erik Mostert, Nicole Kranz, Eduard Interwies, and Jos Timmerman analyse the regime features that contribute to adaptive management of these basins.

Is there a legal right to weather? Weather modification technologies have been used for over 50 years. Clouds are seeded with chemicals in order to induce or prevent rain, hail or snow. In his article, Ralph Czarnecki, Senior Fellow at Ecologic, analyses perspectives on a future weather law against the background of scarcer precipitation and the ensuing problems such as "rain theft" and distributional justice.

Based on the first three years of experience with the European Union Emissions Trading Scheme (EU ETS), the European Commission has put forward its proposals for a review of the scheme on 23 January 2008. This article by Benjamin Görlach, Olaf Hölzer-Schopohl, and Hauke Hermann, a Fellow with Ecologic, summarises some of the main changes proposed by the Commission in response to identified deficits, and outlines some of the most contentious points expected to feature prominently in further debate.

More than any previous year, 2007 saw momentum build for concerted international action on climate change. With a lively public debate and several high-profile events, global warming enjoyed unprecedented media attention and also a prominent place on the political agenda as the year came to an end. In this article, Camilla Bausch, Head of Energy and Climate at Ecologic, and Michael Mehling, Head of the Ecologic office in Washington, D.C., review central developments in the area of international climate policy in the last quarter of 2007.

Finding a place for public participation in the policies and practices of European river basin management planning is a challenge for the authorities in the participating countries and territories. Understanding the relationship between national culture, the historical and political differences in the respective countries, and their practical experience with participation is considered important in the implementation of the EU Water Framework Directive. Knowledge and understanding of this relationship will help to provide a context and basis from which new participatory practices can be designed and experiences evaluated, and will also facilitate the identification of conditions necessary for social learning.

The EU has set ambitious targets to raise the share of renewable energies, particularly biofuels. This article, written by Stephanie Schlegel and Timo Kaphengst, discusses the role that bioenergy plays in the European policy context and the approach the EU is currently following to ensure the sustainability of biofuels. It addresses the limits of the chosen approach, concluding that certification schemes can not serve as the only safeguard for sustainable bioenergy, but need to be complemented by other tools and policies.

Integrated assessment is rapidly spreading as a practice at different levels of governance. However, the choice of using certain tools in an assessment is often not well founded. In this paper, Wouter de Ridder, John Turnpenny, Måns Nilsson and Anneke von Raggamby present a framework that scientifically underpins the role of, and thus choice of, tools within an integrated assessment.

An earlier article by Michael Mehling in American University’s Sustainable Development Law and Policy journal assessed the prospects and legal implications of a link between regional trading systems in the US and the EU emissions trading system, highlighting the relevance of the respective constitutional and legal frameworks for such a link.

The world's natural resources face increasing pressure due to rapid population and economic growth. Ensuring sustainable use of natural resources will require on the one hand a reduction in resource use, as well as strong, efficient and internationally valid standards. The current discussion on certification schemes for biofuels serves as a starting-point for the discussion regarding the possibilities and ways to extend a global sustainability standard with a broad coverage of natural resources. This article by Stephanie Schlegel and Timo Kaphengst outlines how a global sustainability standard for natural resources (NRS) can be designed.

The International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) is the most recent piece in the current regime complex on plant genetic resources. In their article for the Journal of World Intellectual Property, Christiane Gerstetter, Benjamin Görlach, Kirsten Neumann and Dora Schaffrin investigate the legal relationship between the ITPGRFA, the Convention on Biological Diversity, the TRIPS Agreements of the World Trade Organization (WTO) and the Acts of the International Union for the Protection of New Varieties of Plants (UPOV).

Biomass constitutes an important but limited renewable energy source for the future. In this article, Timo Kaphengst discusses sustainability aspects of biomass use for bioenergy in the European context. The article is available for download.

Germany has a very good record on water services. Despite high connection rates and almost full cost recovery, the total annual costs for consumers are at the same level or even cheaper than in other countries. This is an outcome of the specific way in which water management is organised in Germany. This contribution by R. Andreas Kraemer, Britta Pielen and Colette de Roo endeavours to explain the practice of municipal enterprises embedded in Germany’s federal structures, the levels of water services, and reveals why water services can be as good and as cheap as they are.

In their recent article, Dr. Camilla Bausch and Michael Mehling, analyse the main negotiation and discussion tracks under the United Nations for the further evolution of the international climate regime beyond 2012.

Since the signing of the Kyoto Protocol in 1997, climate protection and the reduction of greenhouse gas emissions are binding targets for many countries. However, total global emissions have not reached intended targets, indicated by the continued increase in CO2, which is the most significant greenhouse gas. In 2006 total global CO2 emissions reached 29 Billion tonnes, representing a 2.6% increase over the preceding year and an increase of nearly a third from 1990. In his report, Dr. Hans-Joachim Ziesing, Senior Policy Advisor at Ecologic, presents the development of emissions in the EU and proposes a common implementation of climate protection targets to insure the EU's leading role in climate protection.

The role of renewable energy is increasing globally. Renewable energy sources are supposed to meet half of Germany's energy demand by 2050. In this article, the authors provide an overview on current developments in the law for renewable energy.
