Linking emissions trading schemes has currently attracted much interest as a means of reducing compliance costs, expanding market size and liquidity, and reducing price volatility. The US and Canada are developing federal emissions trading systems, and Mexico is developing an emissions cap for its cement and oil sectors. Strong economic ties imply that linking the systems could become desirable. Linking systems can have both positive and negative implications, but once the decision has been made, framework and policy harmonization is vital to establish and maintain a successful link. Michael Mehling of the Ecologic Institute in Washington, DC co-authored this article.

An unprecedented donation by media mogul Ted Turner in 1997 resulted in the creation of a non-profit charity devoted to helping the United Nations achieve its objectives. The evolution, key activities and figures of the U.N. Foundation are briefly described in this article by Michael Mehling.

Twenty-one countries share the Mediterranean's coastline, with no single country responsible for its environmental deterioration or its protection. They are collectively responsible for both. Over four decades, the environmental dimension of Europe's policy toward its Mediterranean neighbours has become increasingly prominent. This article by Pamela Lesser, Fellow with Ecologic Institute, Washington DC, published in the Mediterranean Quarterly, Volume 20, Issue 2, deals with Europe's environmental policy toward its Mediterranean neighbours and the newly launched Union for the Mediterranean.

Linking emissions trading schemes has attracted interest as a means of reducing costs and expanding market size and liquidity. A number of studies have explored the compatibility of schemes, although little attention has been devoted to the implementation of links. In an article published in the peer-reviewed journal Climate Policy, Michael Mehling, President of the Ecologic Institute in Washington DC, and Erik Haites, former IPCC lead author, identify mechanisms required for the establishment and operation of a trading link over time.

Legal and Institutional Dimensions of the Copenhagen Regime – this is the title of the most recent issue of the Carbon & Climate Law Review (CCLR). Camilla Bausch, Ralph Czarnecki and Michael Mehling edited this issue, which opens the stage for a timely discussion on the most recent international climate negotiations. It features a preface by Congressman Edward J. Markey, who co-authored the successful climate and energy bill for the U.S. House of Representatives.

In this article, Ana Frelih Larsen examines the encounter between biosecurity and semi-subsistence producers in the Slovenian Alps. The article shows that biosecurity, as part of a broader shift in agri-food governance stemming from Slovenia's entry to the European Union, has dramatically reshaped the playing field for semi-subsistence producers, driving agricultural restructuring and diminishing farmers’ strategies of subsistence slaughter and informal marketing.

"Europe's Bid – What we can offer Barack Obama" is the theme of the first issues in 2009 of the journal "Internationale Politik", published by the German Council on Foreign Relations (DGAP).  R. Andreas Kraemer contributed a preview of the possibilities for future cooperation between the US and Europe in climate and energy policy for jointly meeting the transformational challenges ahead, and in the Arctic, where the future of international relations may well be decided.

"A New Transatlantic Partnership" is the theme of the first issue in 2009 of the Global Edition of the journal "Internationale Politik" (IP Global Edition), published by the German Council on Foreign Relations (DGAP). R. Andreas Kraemer contributed a preview of the possibilities for future cooperation between the US and Europe both on climate and energy policy for jointly meeting the transformational challenges ahead and on the Arctic, where the future of international relations may well be decided.

Valuing both the environment and the changes in the level of environmental quality is of central importance to environmental policy formulation, as it puts the costs of obtaining certain environmental goals into perspective. In this article, which was published in the December 2008 issue of "Ökologisches Wirtschaften", Holger Gerdes and Anneke von Raggamby propose a methodology to assess the policy impacts of environmental valuations.

In 2006/2007, climate change experienced both a remarkable and unexpected increase in significance in political and public perception. In Germany, the grand coalition took up the issue and chancellor Angela Merkel gave climate change top priority for both the German EU-Presidency and "her" G8-Summit. Dr. Camilla Bausch and Benjamin Görlach take stock of German climate policy since the dual presidency in 2007 and provide an outlook for the future.

Looking at the Amudarya river basin in Central Asia, Ecologic Institute's Nicole Kranz, Holger Gerdes and Cornelius Laaser elaborate in this article on how the NeWater project assists with the development of new water governance tools in transboundary river basins. The article was published in the Fall 2008 issue of Schlossplatz³ by the Hertie School of Governance.

The hope for a reversal in the growth of greenhouse gas emissions – especially CO2-emissions – was not fulfilled again this year. Nevertheless, greenhouse gas emissions in Annex-B-countries, which (except the USA) committed to emissions caps or reductions, decreased in 2007 by 0.7% from 2006 levels – by 16% from 1990 levels. Ecologic Policy Advisor Hans-Joachim Ziesing’s article, published in "Energiewirtschaftliche Tagesfragen" Vol. 58, Issue 9, presents an overview of trends in the development of global C02 emissions and greenhouse gas emissions in Annex-B-countries, from 1990 to 2007.

No international regime operates in complete isolation from other regimes and the wider body of international law. Conflicts and tensions, but also potential synergies, are inevitable consequences of regime coexistence. Such interactions are particularly apparent in the case of the climate regime, which is analysed in this article in relation to the international law on biodiversity protection and free trade.
