Coherence and Comprehensiveness: An American Foreign Policy Imperative

| March 2019

As the United States now confronts the prospect of a multi-faceted and quite possibly generational competition with China—underscored not only by recent Trump Administration public statements but also by the clear emergence of bipartisan support for a firm posture against certain Chinese practices—it is essential that U.S. policymakers take steps to ensure our approach is as coherent and comprehensive as possible. (As we make this point, we offer our hope that the relationship between the U.S. and China, unquestionably the most important in the world, can evolve into one that is mutually beneficial and avoids confrontation.

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

| 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.
