Recent elections in the European Union shook up the continent's climate politics. Far-right parties performed well in both the EU's parliament and national governments, and the Greens lost nearly all of their gains over the past five years in the European parliament. Voters pointed to energy costs, security, and economic competitiveness as key factors in their decision-making.

So what do these elections indicate about the shifting political ideology of the European Union? How will they impact Europe's relations with the U.S. and China? And what do these elections mean for European climate and energy policy?

This week, host Jason Bordoff talks with Ann Mettler, vice president for Europe at Breakthrough Energy, a network of investment funds, philanthropies, and nonprofits dedicated to scaling low-carbon technologies. She previously served as director-general at the European Commission, where she ran an in-house think tank called the European Political Strategy Centre. Prior to that, she was the executive director of the Lisbon Council, an economic policy think tank she founded in 2003.

Jason and Ann discuss the results of the recent European elections, the economic competitiveness challenges facing the European Union, and Ann's views on Europe's new tariffs on China.
