Scott Pruitt would like to get “co-benefits” discounted from the calculus used to determine environmental regulation. This is an insane idea and will definitely make regulations harder to pass; unending parade of ethical violations keeps grabbing headlines, but his dogged efforts to dismantle environmental safeguards that protect the health and well-being of Americans should concern us the most. Some of these efforts are obvious, like repealing power-plant pollution limits or rolling back vehicle-emissions standards. His most recent move, however, is more insidious. His term 'Co-benefits' refer to any positive effects a regulation might have outside of the one directly targeted by the rule. he already took this approach in proposing to repeal the Clean Power Plan, which seeks to limit greenhouse gas emissions from existing power plants."
