MONTPELIER, Vt. (AP) — The state of Vermont is among 22 states and two cities trying to block the Trump administration from ending California’s authority to set greenhouse gas emission and fuel economy standards for cars and trucks.
Federal law generally regulates vehicle pollution, but California has been allowed to impose tougher rules since the 1970s.
The legal challenge builds on a similar lawsuit it filed in September, a day after the National Highway Traffic Safety Administration withdrew California's waiver.
Vermont is one of 13 states and the District of Columbia that have adopted California's standards.
Vermont Attorney General T.J. Donovan said Friday that protecting the environment is a Vermont value and the state will continue to oppose any federal action that threatens the state’s ability to limit greenhouse gas emissions.
