Now in its seventh edition, Economics of the Environment serves as a valuable supplement to environmental economics text books and as a stand-alone reference book of key, up-to-date readings from the field. Edited by Robert N. Stavins, the book covers the core areas of environmental economics courses as taught around the world; and the included authors are the top scholars in the field. Overall, more than half of the chapters are new to this edition while the rest have remained seminal works.

"Belfer Center Newsmakers" highlights members of the Belfer Center community who have been featured recently in the news.

The authors draw upon the past decade of experience with carbon markets to test a series of hypotheses about why governments have demonstrated a preference for linking.

Professor Robert Stavins, Harvard Project Director, recently published the second volume of his collected papers with Edward Elgar Publishing. The 26 essays in the volume cover a wide range of topics, including: environmental policy analysis; economic analysis of environmental policy instruments; economics and technical change; natural resource economics — land and water; and domestic and international climate change policy. The first volume of Professor Stavins' papers was published in 2000 — also by Edward Elgar — covering the period 1988–1999.

The outcome of the December 2011 United Nations climate negotiations in Durban, South Africa, provides an important new opportunity to move toward an international climate policy architecture that is capable of delivering broad international participation and significant global CO2 emissions reductions at reasonable cost. This paper addresses an important component of potential climate policy architecture for the post-Durban era: links among independent tradable permit systems for greenhouse gases.

Harvard Project on Climate Agreements Director Robert N. Stavins delivered a presentation titled "Climate Change: Efficiency and Equity," at The Graduate Institute in Geneva, Switzerland, on November 29, 2011. The talk was one in the Geneva Environmental Dialogue Series of public keynote lectures that the Institute holds annually on a theme related to the international environment. The theme for the 2011–2012 term is "Justice and the Environment."

Because of the global commons nature of climate change, international cooperation among nations will likely be necessary for meaningful action at the global level.  At the same time, it will inevitably be up to the actions of sovereign nations to put in place policies that bring about meaningful reductions in the emissions of greenhouse gases.  Due to the ubiquity and diversity of emissions of greenhouse gases in most economies, as well as the variation in abatement costs among individual sources, conventional environmental policy approaches, such as uniform technology and performance standards, are unlikely to be sufficient to the task.  Therefore, attention has increasingly turned to market-based instruments in the form of carbon-pricing mechanisms.  We examine the opportunities and challenges associated with the major options for carbon pricing:  carbon taxes, cap-and-trade, emission reduction credits, clean energy standards, and fossil fuel subsidy reductions.
