This issue of the Carbon & Climate Law Review (CCLR) provides an up-to-date analysis of recent developments in greenhouse gas regulation and climate policies in Canada and the United States, identifying new opportunities for transatlantic cooperation. Michael Mehling, president of the Ecologic Institute in Washington, D.C., edited this issue of the CCLR.

Corruption in the development sector had been a ‘no issue’ until the beginning 1990s. It was assumed that safeguards and controls were put in place somehow and that corruption could cause nothing worse than costs on top of development aid projects. Evidence has since been gathered that shows the lack of access to clean water supply, sanitation and sustainable ecological development is not due to a lack of natural resources nor of technical solutions: It is a crisis of governance. Grit Martinez, Fellow at Ecologic, and Kathleen Shordt elaborate the role and responsibilities of donors in the fight against corruption in the water sector.

Past energy policies are largely to blame for climate change, and now, more than ever, the security implications demand a transformation of energy systems and infrastructure. In this commentary, R. Andreas Kraemer, Director of Ecologic, argues that such a transformation would be possible both technically and economically, but that it requires political will and coordinated action and would need to be accompanied by reform of international institutions.

In recent years, the debate on trade and the environment seemed to lose some of its earlier controversy: after a string of highly polarizing cases before the WTO, the Appellate Body’s Article 21.5 Implementation Report in the Shrimp/Turtle case appeared to finally herald a period of reconciliation between free trade and environmental concerns. Upon closer analysis, however, this assessment proves to be misleading: as a matter of substantive law, the chasm between both issue areas is still substantial.

The EC-Water Framework Directive (WFD) stipulates that all water bodies have to achieve good status or good ecological potential by 2015. It is conceivable, though, that most of the German water bodies will not meet these objectives. Many German Laender will therefore request a time extension from the EU. The authors, along with Ingo Bräuer, Senior Fellow with Ecologic, discuss in their article how exemptions can be justified transparently and in accordance with the requirements of the Directive.

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).
