This report discusses various cooperative international efforts to address the issue of global climate change. The two major international agreements discussed in a side-by-side comparison are the 1997 Kyoto Protocol and the 2010 Copenhagen Accord. The report discusses how many observers are hoping that initiatives carried out under the Copenhagen Accord may help bridge divides between the various tracks and economic groupings established under the Kyoto Protocol.

This report discusses recent legislative initiatives seeking to establish climate change impacts as a common law nuisance. The report explains what private and public nuisances are, the issues faced by policymakers when litigating a climate-change/nuisance suit, and also discusses five climate-chance/nuisance suits that are now or formerly active, as a basis of comparison. The report also explores arguments of those both for and against addressing the complex issue of climate change through common law suits.

The nation's energy choices embody many tradeoffs. Water use is one of those tradeoffs. The energy choices before Congress represent vastly different demands on domestic freshwater. The energy sector's water consumption is projected to rise 50% from 2005 to 2030. This rising water demand derives from both an increase in the amount of energy demanded and shifts to more water-intense energy sources and technologies. This report discusses this issue as well as related issues that may arise for the 112th Congress.

The aim of this report is to provide strategic guidance to U.S. policymakers on engaging China on climate change. In the first section, I set the context by discussing China’s energy use, emissions, and future projections, including potential emissions reductions and trajectories under different policies. In section two, I review China’s recent policies to address climate change and energy conservation. I focus on the status of implementation of its energy-efficiency goals under its 11th Five Year Plan. I also anticipate future developments in Chinese energy and climate policy. Finally, in section three, I propose a strategy for U.S. engagement of China on climate change.
