EPA's Proposal to Rescind 2009 Endangerment Finding and the Impact of 'Loper Bright'

The EPA has proposed rescinding its 2009 “endangerment finding,” the foundation for federal greenhouse gas regulations. The agency argues that the Supreme Court’s 2024 decision in Loper Bright v.

Neighboring States Have Either Passed or Proposed Climate Superfund Laws - Is Pennsylvania Next?

Following Vermont and New York’s enactment of a Climate Change Superfund Act, New Jersey, Maryland, Massachusetts and California are proposing their own superfund laws, which Marc Rollo, Charlie Dennen and Grace Baccare discuss in The Legal Intelligencer article, “Neighboring States Have Either Passed or Proposed Climate Superfund Laws— Is Pennsylvania Next?”. These states are seeking to impose liability on certain responsible parties for damages caused by extracting fossil fuels or refining crude oil. Compensatory payments would be collected from responsible parties and allocated to a climate superfund cost recovery program. While these proposals have not yet been enacted, they do serve as an indicator that more states will propose their own law, including perhaps Pennsylvania. However, the U.S. Chamber of Commerce and American Petroleum Institute are pushing back and recently filed a lawsuit against the state of Vermont, arguing that their version of the climate superfund law is an overreach of state power. New York will likely face the same legal challenge. ...read more
