The Environmental Protection Agency struck a blow against climate change Tuesday, setting the first limits on greenhouse gasses emitted by U.S. power plants. “We’re taking a common-sense step to reduce pollution in our air, protect the planet for our children, and move us into a new era of American energy,” the EPA said in a statement. Power plants are the largest source of carbon dioxide, a greenhouse gas. The new restrictions would apply only to newly constructed plants and would exempt plants built in the next year.
