Environment & Climate Change

Robert Stavins argues for an economic approach to solving environmental problems and explains why "environmental economics" is not an oxymoron.

The United States has considerable tax administration and cap-and-trade expertise that could highlight potentially successful carbon pricing approaches. Although this experience is not climate-related, the United States deploys an efficient and highly compliant excise tax system, and it could assist developing country efforts to build their own capacity to tax carbon. The United States also has long experience with cap-and-trade systems for criteria air pollutants, much of which is transferable to greenhouse-gas emissions trading.

The Kyoto Protocol establishes a very complex and ambitious regime, in architecture if not stringency. The problem is that relatively few states, representing only about a quarter of the world's emissions, have been willing to assume emission targets under Kyoto....The future of the Protocol thus seems doubtful at best. Even in the most optimistic scenario, a new round of emissions targets couldn't be agreed in time to prevent a legal gap between the first and second commitment periods. A possible middle ground would be to establish a transitional regime that would be political in nature, but that could evolve over time into a legally-binding regime.

Dramatic growth in nuclear energy would be required for nuclear power to provide a significant part of the carbon-free energy the world is likely to need in the 21st century, or a major part in meeting other energy challenges. This would require increased support from governments, utilities, and publics around the world. Achieving that support is likely to require improved economics and major progress toward resolving issues of nuclear safety, proliferation-resistance, and nuclear waste management. This is likely to require both research, development, and demonstration (RD&D) of improved technologies and new policy approaches.

Negotiations under the United Nations Framework Convention on Climate Change (UNFCCC) at Copenhagen in December 2009 did not produce a new international treaty with binding emissions commitments, but have defined a roadmap for dealing with global climate change in the post-2012 era. As countries continue to pursue new models for global agreement, it will be important to learn from the weaknesses of past approaches, while building on positive aspects of the experience with the Kyoto Protocol so far.

This policy brief is based on Belfer Center paper #2010-02 and an article published in Energy Policy, Vol. 38, No. 3.

Oil security and the threat of climate disruption have focused attention on the transportation sector, which consumes 70% of the oil used in the United States.
This study explores several policy scenarios for reducing oil imports and greenhouse gas emissions from transportation.

Will the Obama administration's plan for vehicle emissions standards and auto efficiency affect consumer behavior? During today's OnPoint, Kelly Sims Gallagher, director of the Energy Technology Innovation Policy research group at the Harvard Kennedy School's Belfer Center, gives her take on the administration's recent auto emissions announcement and whether it will have any significant effects on the environment. Gallagher, editor of the new report, "Acting in Time on Energy Policy," explains why she believes Congress should consider a variable tax on the price of oil as part of the United States' energy policy.

This policy brief outlines urgent priorities for U.S. energy policy at the dawn of the Obama administration, and recommends specific steps that the U.S. government should take to address the numerous energy-related challenges facing the United States. It is based on the book, Acting in Time on Energy Policy (Brookings 2009), edited by Kelly Sims Gallagher, director of the Energy Technology Innovation Policy research group at the Harvard Kennedy School's Belfer Center.

We concentrate on six topics: climate change policy, carbon capture and storage policy, oil security policy, energy-technology innovation policy, electricity market structure, and infrastructure policy. The United States cannot afford to wait any longer to enact long-term policies on these topics. In fact, acting early is clearly in the longer-term interest of the United States.

Global efforts to address climate change may be on a collision course with global efforts to reduce barriers to trade.  This paper discusses the broad question of whether environmental goals in general are threatened by free trade and the WTO, before turning to the narrower question of whether trade policies likely to be included in various national efforts to address climate change are likely to come into conflict with WTO rules.
