State attorneys general have a new weapon in their efforts to halt the rollback of federal environmental regulations.

New York University School of Law has launched the State Energy & Environmental Impact Center, which will serve as a resource for attorneys general across the country who are fighting to preserve climate, clean energy, and other federal environmental protection initiatives through the courts.

It's the first law school center focused specifically on state attorneys general and the environment, and is being funded through a nearly $6 million donation from Bloomberg Philanthropies—the charity of billionaire and former New York City Mayor Michael Bloomberg.
