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.

Over the last three years, projects that address the relationships between carbon and forests have moved from the sidelines of international climate action to center field. Forestry’s recent advancements are the product of decades of ongoing collaboration among market and environmental experts seeking to strike an ideal balance between forestry projects’ market risks and shared benefits. Market dynamics in 2011 demonstrated that these efforts have never been more pivotal, or complex, as forest carbon projects mature – and find themselves positioned squarely in the midst of some of today’s most challenging policy debates. This year, a record number of forest project developers and secondary market suppliers from around the world shared data about their projects and transactions. This third annual State of the Forest Carbon Markets tracks, reports, and analyzes trends in these responses. This information is primarily based on data collected from respondents to Ecosystem Marketplace’s 2011 forest carbon project developer’s survey, combined with data from the 2012 State of the Voluntary Carbon Markets report. The data and analysis that follow cover forest carbon activity in compliance carbon markets – including the Kyoto Protocol’s Clean Development Mechanism (CDM), the New Zealand Emissions Trading Scheme (NZ ETS), the New South …

"A Blueprint for Ocean and Coastal Sustainability", jointly prepared by UNDP’s Water & Ocean Governance Programme, IOC/UNESCO, FAO and IMO, contextualizes and sets forth a series of ten tangible proposals to shift the oceans management paradigm towards sustainability, and is intended to inform and influence possible Rio+20 outcomes on oceans.

This Synthesis Report is based on the reports of the three Working Groups of the Intergovernmental Panel on Climate Change (IPCC), including relevant Special Reports. It provides an integrated view of climate change as the final part of the IPCC’s Fifth Assessment Report (AR5). This summary follows the structure of the longer report, which addresses the following topics: Observed changes and their causes; Future climate change, risks and impacts; Future pathways for adaptation, mitigation and sustainable development; Adaptation and mitigation.

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.
