The head of the Environmental Protection Agency has announced a series of actions to roll back landmark environmental regulations, including rules on pollution from coal-fired power plants, climate change and electric vehicles.

The EPA administrator says he is rolling back dozens of environmental rules, including those crucial to California programs on climate change and electric vehicles, and closing offices that worked to lower pollution in poor communities.

The Environmental Protection Agency didn't provide details about what it wants to do with the regulations — whether it will try to weaken them or eliminate them entirely.
