The United States is officially back “in the game,” leading the fight against climate change, said US Representative Kathy Castor, chair of the House Select Committee on the Climate Crisis. “And we’re not leaving the playing field ever again.”

Castor and House Speaker Nancy Pelosi spoke on Thursday about how the United States is addressing the climate crisis at an Atlantic Council Front Page event hosted by the Adrienne Arsht-Rockefeller Foundation Resilience Center at the United Nations Climate Change Conference of the Parties (COP27) in Sharm el Sheikh, Egypt.

While the United States—which withdrew from the Paris Climate Accords in 2019 but rejoined the agreement in 2021—has seen its climate leadership questioned, Castor said the country now has the tools to meet its emissions reduction goals. Those tools, she explained, include the bipartisan infrastructure law and the Inflation Reduction Act (IRA), the latter of which she deemed the “most important climate bill” in US history.
