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.

Most of the actions are reconsiderations of existing policies, including regulations on power plants, the oil and gas industry, vehicles and wastewater. Standards for mercury, pollutants, greenhouse gas emissions and air quality are also being reviewed.

Environmental Protection Agency administrator Lee Zeldin on Wednesday outlined plans for an aggressive rollback of environmental regulations.
