The Environmental Protection Agency on Thursday announced a proposal for the tightest limits ever on power plants' planet-warming pollution, a policy it must enact to meet President Biden's pledge to halve U.S. emissions by 2030 compared with 2005 levels.
The move, which builds on two major spending bills Congress has passed since 2021 and several other rules the EPA has proposed this year, targets the country's second-largest source of greenhouse gas emissions. It would encourage gas- and coal-fired plants nationwide to meet tighter emission-reductions standards by either closing or adopting technology to run cleaner, accelerating one of the fastest transitions underway in energy.
