The Environmental Protection Agency finalized new rules Thursday requiring coal-fired power plants to either cut or capture 90% of their carbon dioxide emissions by 2032 or shut down. Power plants are the second-largest source of greenhouse gas emissions after transportation. But climate groups criticized the regulations’ reliance on unproven technologies rather than reducing fossil fuel usage. The group Food & Water Watch said, “Pretending that carbon capture can dramatically reduce climate pollution is nothing but a dangerous fantasy.”
