Transitioning to Long-Run Effective and Efficient Climate Policies

| April 2019

This paper evaluates factors affecting the potential to transition over time to more efficient longrun climate policies, including the sequence of policies to be adopted. By considering these factors, policymakers can increase the likelihood that more efficient policies emerge from the current suite of less-efficient measures being pursued by some national and sub-national governments. The authors focus on the state of Oregon, which is currently contemplating the adoption of a greenhouse-gas cap-and-trade system.

The Future of U.S. Carbon-Pricing Policy

| May 2019

There is widespread agreement among economists — and a diverse set of other policy analysts — that at least in the long run, an economy-wide carbon pricing system will be an essential element of any national policy that can achieve meaningful reductions of CO2 emissions cost-effectively in the United States. There is less agreement, however, among economists and others in the policy community regarding the choice of specific carbon-pricing policy instrument, with some supporting carbon taxes and others favoring cap-and-trade mechanisms. This prompts two important questions. Which — if either — of the two major approaches to carbon pricing is superior in terms of relevant criteria, including but not limited to efficiency, cost-effectiveness, and distributional equity? And which of the two approaches is more likely to be adopted in the future in the United States?

Holdren gave a lecture for students and faculty at Tsinghua University's School of Public Policy and Management on the latest climate science as it affects the Arctic.  He discussed efforts to understand the challenges affecting the region and the global community and what further worldwide actions are required to address these challenges.

Key Challenges for China's Carbon Emissions Trading Program

| May 2019

China's national carbon emissions trading program is expected to become the world's largest carbon market and is critical for achieving China's domestic mitigation goals. But China's trading program is likely to face significant challenges, due to its large scale and high complexity. To address these challenges, we provide a series of policy recommendations, including capacity building from central to local levels, wise selection of allowance allocation methods to cope with changing economic realities, and deepening market-oriented reforms in energy sectors and SOEs.
