Environment & Climate Change

Despite the opposition that appears now in China-U.S. relations, cooperation is far more important, underscored prominent U.S. political scientist Dr. Joseph S. Nye during an exclusive interview with Wang Xiaohui, editor-in-chief of China.org.cn, on Jan. 10, 2019.

Indian Prime Minister Narendra Modi traveled to Washington last week, making his fourth trip to the United States since taking office just two years ago. India and South Asia Program Fellow, Ronak Desai examines the strategic approach to India's relations with the United States.

"The role of market mechanisms for reducing greenhouse-gas emissions and the relationship between climate change policy and international trade were the topics of a side-event panel discussion on Friday at the Conference of the Parties (COP21), the United Nations Conference on Climate Change in Paris. The panel discussion, which was co-sponsored by the Harvard Project on Climate Agreements, addressed a variety of issues related to the emissions-reduction targets that countries are putting forward as part of a new agreement to be concluded in Paris."

Professor Meghan O'Sullivan was interviewed on November 15th, 2015 for a Wall Street Journal special section on energy, discussing the rapid transformation of the American energy sector in light of low fuel prices, new climate policies and other factors.

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

The Renewable Fuel Standard (RFS) is among the cornerstone policies created to increase U.S. energy independence by using biofuels. Although greenhouse gas emissions have played a role in shaping the RFS, water implications are less understood. We demonstrate a spatial, life cycle approach to estimate water consumption of transportation fuel scenarios, including a comparison to current water withdrawals and drought incidence by state. The water consumption and land footprint of six scenarios are compared to the RFS, including shale oil, coal-to-liquids, shale gas-to-liquids, corn ethanol, and cellulosic ethanol from switchgrass.

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.

Over the last decade, carbon trading has emerged as the policy instrument of choice in the industrialized world to address global climate change. This paper argues that a transnational business coalition, representing mostly energy firms and energy-intensive manufacturers, actively promoted the global rise of carbon trading. In this process, business could draw on the support of government allies and business-oriented environmental groups, particularly in the UK and the US.
