The Supreme Court today upheld a contentious EPA rule enacted in 2011, mandating “polluting states … to reduce smokestack pollution that sullies the air in downwind states,” according to the Associated Press. The EPA claims “the investments would be far outweighed by the hundreds of billions of dollars in health care savings from cleaner air,” the AP reports, and “the rule would prevent more than 30,000 premature deaths and hundreds of thousands of illnesses each year.” Ironically, Administrator Gina McCarthy recently admitted that the agency used fraudulent data when crafting the Clean Air Act; this week she vowed to silence “critics … challenging the credibility of world renowned scientists and institutions like Harvard University and the American Cancer Society.” Don’t worry – this time the science is settled.
