The US Environmental Protection Agency (EPA) unveiled a plan to repeal a landmark climate rule that aims to mostly eliminate greenhouse gases from power plants by the 2030s and weaken another regulation that restricts power plants' release of hazardous air pollutants. The proposal, announced by EPA Administrator Lee Zeldin,

The Trump administration announced plans to erase limits on greenhouse gases from power plants and weaken restrictions on hazardous emissions, including mercury, arsenic, and lead. The proposed changes aim to unshackle the coal, oil, and gas industries from regulations imposed by the Biden administration, according to Lee Zeldin, the administrator
