“The EPA’s proposed rule sends an unequivocal signal to American power plant operators: the era of unlimited carbon pollution is over,” said Dan Lashof, US director of the World Resources Institute, who added that the regulation would result in more than an 80% reduction in carbon pollution from power plants by 2040 compared to 2005 levels. “This administration is determined to advance its radical climate agenda and has made it clear they are hellbent on doing everything in their power to regulate coal- and gas-fueled power plants out of existence,” said Manchin, who vowed, as chairman of the Senate’s energy and natural resources committee, to block all EPA nominees in protest over the rule.
