Following decades of economic integration, the cost of clean energy technologies have fallen sharply. But the rising costs of fragmentation, industry-friendly policies, and geopolitical tensions risk slowing the energy transition.  With the recent launch of the Trade and Clean Energy Transition initiative, the Center on Global Energy Policy has prioritized navigating the tensions between climate and trade, and focused on the potential to use trade policy as a tool to accelerate the pace of clean energy deployment. So how can the rules of trade be better aligned with climate goals and policies? How can the international trading system be modernized to tackle a challenge like climate change? And how can countries reconcile low-cost, clean energy technologies, often made in China, with concerns about economic competitiveness, security, and supply chain resilience? This week, we return to a conversation from earlier this year between host Jason Bordoff and Dan Esty focused on Dan’s career, his recent work at the World Trade Organization, and the intersection of climate policy and trade policy. Dan is the Hillhouse Professor at Yale University and director of the Yale Center for Environmental Law and Policy. He has written numerous books on environmental responsibility and economic progress, including Green to Gold and Greening the GATT. Dan also served as commissioner of Connecticut’s Department of Energy and Environmental Protection from 2011 to 2014.
