EPA rolls back Biden-era power-plant emissions rules, citing authority limits

The US Environmental Protection Agency announced it will scrap most Biden-era rules limiting emissions from coal- and gas-fired power plants, saying the rules exceeded the agency’s authority and will seek to remove other greenhouse-gas rules for the sector. Officials say the move could save about $310bn and lower energy prices while maintaining safeguards, but environmental groups warn it could worsen public health and climate and expect immediate legal challenges.
