Belfer Center Newsletter Spring 2011

| Spring 2011

The Spring 2011 issue of the Belfer Center newsletter features recent and upcoming activities, research, and analysis by members of the Center community on critical global issues. This issue highlights the Belfer Center’s continuing efforts to build bridges between the United States and Russia to prevent nuclear catastrophe – an effort that began in the 1950s. This issue also features three new books by Center faculty that sharpen global debate on critical issues: God’s Century, by Monica Duffy Toft, The New Harvest by Calestous Juma, and The Future of Power, by Joseph S. Nye.

Comparing Climate Commitments: A Model-Based Analysis of the Copenhagen Accord

    Authors:
  • Warwick McKibbin

  • Peter Wilcoxen
| June 2010

The authors compare the targets and actions to which countries have committed under the Copenhagen Accord. The Accord allows participating countries to express their commitments to reduce greenhouse-gas (GHG) emissions in a variety of ways—most broadly, through economy-wide quantified emissions targets for developed countries and mitigation "actions" by developing countries. These are difficult to compare. However, even mitigation commitments that look similar can require very different levels of effort in different countries, and commitments that produce similar economic outcomes can look inequitable. These variations in effort and equity depend on historical patterns of energy use, marginal costs of greenhouse-gas abatement, choice of base year, methods for determining "business as usual" projections, and other factors.

The Regime Complex for Climate Change

    Authors:
  • Robert O. Keohane

| January 2010

There is no integrated, comprehensive regime governing efforts to limit the extent of climate change. Instead, there is a regime complex: a loosely coupled set of specific regimes. We describe the regime complex for climate change and seek to explain it, using functional, strategic, and organizational arguments. It is likely that such a regime complex will persist: efforts to build an effective, legitimate, and adaptable comprehensive regime are unlikely to succeed. Building on this analysis, we argue that a climate change regime complex, if it meets specified criteria, has advantages over any politically feasible comprehensive regime, particularly with respect to adaptability and flexibility. These characteristics are particularly important in an environment of high uncertainty, such as in the case of climate change where the most demanding international commitments are interdependent yet governments vary widely in their interest and ability to implement such commitments.

Climate Team Suggests Post-Kyoto Ideas

| Spring 2009

A new report from the Harvard Project on International Climate Agreements outlined several promising ideas for successors to the Kyoto Protocol ... guidance on the most intractable challenges facing global climate negotiators, including participation by developing countries, how to reduce deforestation, and how to prevent a "collision" between climate policy and international trade law

Architectures for Agreement: Addressing Global Climate Change in the Post-Kyoto World

| September 2007

The Kyoto Protocol serves as an initial step to mitigate the threats posed by global climate change but policy-makers, scholars, businessmen, and environmentalists have begun debating the structure of the successor to the Kyoto agreement. Written by a team of leading scholars in economics, law and international relations, this book contributes to this debate by examining the merits of six alternative international architectures for climate policy.
