A Reckoning for Core US Climate Finding

The US Environmental Protection Agency plans to rescind the foundation of its authority to regulate greenhouse gas emissions under the Clean Air Act.

Eliminating the so-called "endangerment finding" is a key part of President Trump's efforts to reverse Obama- and Biden-era climate policy. The finding was also targeted in the conservative Project 2025 strategy to reshape the federal government. But the rollback won't happen without a fight, and the endangerment finding has held up to past legal challenges.

Meanwhile, international courts are moving in the opposite direction. The International Court of Justice recently ruled that countries have legal obligations to address climate change and that fossil fuel subsidies could constitute "internationally wrongful acts."

So what would overturning the endangerment finding mean for US climate policy? What legal and scientific arguments is the administration using? And how do these conflicting domestic and international trends shape the future of energy and climate policy?

This week, Bill speaks to Michael Gerrard about how the EPA is rescinding its own ability to regulate greenhouse gases.

Michael is the founder and faculty director of Columbia's Sabin Center for Climate Change Law. Before joining Columbia in 2009, Michael practiced environmental law in New York for three decades.
