President Barack Obama and Environmental Protection Agency head Gina McCarthy are releasing a final version of the Clean Power Plan today, the first national standards to cut carbon pollution from power plants.
The regulations require power plants to cut carbon dioxide emissions 32 percent from 2005 levels by 2030. Carbon dioxide is among the leading causes of climate change, and Obama has said that fighting climate change is as central to his legacy as the Affordable Care Act. The plan also requires power plants use more renewable sources of energy, including wind and solar.
Industry groups and coal companies, and coal producing states including Wyoming and West Virginia have vowed to challenge the rules.
