When the Environmental Protection Agency finalized the Clean Power Plan in 2015 it exercised its authority to regulate carbon dioxide emissions to protect public welfare. The Plan, now the focus of escalating debate, also put the nation on course to meet its goals under the Paris Climate Agreement. Given that other pollutants are emitted from power plants—along with carbon dioxide—research has shown that carbon emission standards for the power sector benefit human health. New research released today shows that they would also benefit crops and trees.
