Fourteen attorneys general promised to keep working on climate change initiatives in their jurisdictions after filing a brief with a federal court supporting the Obama administration’s top environmental regulation.

Led by New York Attorney General Eric Schneiderman, attorneys general from 11 other states, the U.S. Virgin Islands and the District of Columbia committed to working on climate change initiatives in their own states. Among the proposed ideas are investigating whether fossil fuel companies in their states misled investors about the impact of climate change on their businesses.
