The US is finally regulating airplane emissions but the rules are worthless

Over the years, as the US has haltingly tried to restrict greenhouse gas emissions from cars and trucks, airplanes have managed to fly through the cracks. On July 22, the Environmental Protection Agency is expected to introduce the first-ever emissions regulations for airplanes in the United States. The EPA’s regulations are designed to match standards that were first suggested in 2017 by the UN agency that oversees international flights.
