Environment & Climate Change

Harvard Kennedy School hosted Sarah Ladislaw, Special Assistant to the President and Senior Director for Climate and Energy of the U.S. National Security Council, for an Energy Policy Seminar on the U.S. approach to energy and climate issues in its foreign policy.

New forms of international cooperation and technology competition with China are the main drivers of public investment in energy innovation, though it remains insufficient to help meet climate goals.

Last week, U.S. Sen. Joe Manchin seemingly dashed Democrats’ hopes for congressional action to slow climate change. Sen. Bernie Sanders accused Manchin of “sabotag[ing] the president’s agenda”; Rep. John Yarmuth, when asked about the consequences of Congress not acting on climate change, said, “We’re all going to die”; and climate activists, as well as some Democrats in Congress, wondered if Manchin should be removed as chair of the Senate Energy and Natural Resources Committee.

For many, integrating “decarbonization” into public policy, corporate and financial strategies has become a requirement, not an option — yet, what happens when the critical link between climate stability and decarbonization breaks?

In recent years, the relationship between China and the United States has been characterized by rising geopolitical tensions, and cooperation and coordination between the two countries has become something of a pipe dream. Yet there is one issue where the interests of both clearly overlap: climate change. A global temperature increase of 3°C will damage the economies and social fabric of both the United States and China—an outcome that both countries want to avoid. 

Article 6 is one of the thorniest issues in climate negotiations and determines how countries trade emissions. In Glasgow, countries finally found an agreement on this thorny issue, whose rules have the potential to support the achievement of the Paris Agreement’s goals at a lower cost and provide larger incentives for private sector investments, writes Marinella Davide.

While China is building nuclear reactors faster than any other country in the world, major constraints may limit nuclear energy’s ability to grow to the scale of hundreds of gigawatts that would be required for it to play a major part in decarbonizing China’s energy system. This chapter explores the major constraints on, and risks of, large-scale nuclear energy growth in China, and how both new policies and new technologies might address them. It focuses particularly on the two biggest constraints – economics and siting. Substantial government policies to support nuclear power and advanced reactor systems designed to address some of the key constraints are both likely to be needed for nuclear to have a chance of playing a major role in decarbonizing China’s energy system; nuclear energy’s role may be bigger in the second half of this century than in the first half.

Professor Joseph Aldy says the incoming U.S. administration can breathe new life into global efforts against climate change, but faces daunting political and economic obstacles.

President-elect Joe Biden’s decision to create a new cabinet-level position for climate-related issues — and to choose so prominent a figure as former Secretary of State John Kerry to fill it — demonstrates Biden’s sincerity over putting climate at the very center of U.S. foreign policy. It is easy to understate the importance of this appointment, given the flurry of czars created by most new administrations.
