On April 28, 2015, the Center on Global Energy Policy hosted the 2015 Columbia Global Energy Summit. Structured as a half-day forum, the Summit included keynote remarks, interviews and plenary conversations with senior energy sector leaders focused on key issues and questions at the intersection of energy policy, financial markets, the environment and geopolitics. The podcast will be delivered in five parts, one for each of the keynote speakers and plenary discussions. Part I features opening remarks, followed by keynote remarks and a conversation with Gina McCarthy, Administrator of US Environmental Protection Agency, moderated by Center on Global Energy Policy Inaugural Fellow David Sandalow.
