Environment & Climate Change

The economist and HKS professor is passionate about solving what may be humanity's most important and perplexing problem: How to untangle fossil fuels from the global economy.

Joseph Aldy describes the challenge of reforming fossil fuel subsidies, given uncertainty about how much subsidies actually cost governments and given provisions in the US tax code that privilege fossil fuels over renewable energy sources. Aldy also elaborates on some policies that the Biden administration—which has committed to removing fossil fuel subsidies—could target as policymakers develop infrastructure legislation.

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.

Former White House advisor Jason Bordoff, professor and founding director of the Center on Global Energy Policy at Columbia University School of International and Public Affairs (SIPA), says the incoming Biden-Harris Administration will have the opportunity to both lift the nation out of recession and combat global climate change by crafting a thoughtful economic stimulus plan containing a significant green energy investment component.

Former U.S. lead climate negotiator Sue Biniaz shares her thoughts on the postponement of COP26 in this interview by Professor Robert Stavins. Stavins and Biniaz explore ways to reimagine future United Nations climate negotiations, unresolved concerns from COP25, and how the United States might approach rejoining the Paris Agreement.
