The U.S. Postal Service's decision to increase its share of electric vehicles marks a modest climate and public health victory during a time when deep greenhouse gas emission cuts seem out of reach. After three lawsuits and an intense pressure campaign from Democratic lawmakers, environmental groups and the White House, the quasi-independent agency said Wednesday that 50 percent of its initial order of new vehicles will be electric. That's a substantial increase from the 20 percent it had initially slated. The stakes are significant. The transportation sector is the country's single largest source of carbon emissions, and USPS uses more energy than any other federal agency. But last year the agency announced a 10-year, multibillion-dollar contract to replace as many as 165,000 delivery trucks with 90 percent gasoline-powered vehicles. The move flew in the face of President Joe Biden's directive to replace all 645,000 federal cars and trucks with electric models. With its 220,000 mail trucks, USPS operates more than a third of all federal vehicles — the world's largest civilian fleet — making it critical to helping achieve Biden's goal. The agency has now committed to a minimum purchase of 84,500 electric vehicles over the next decade to replace its fleet of Grumman Long Life Vehicles, many of which are over 30 years old. The old trucks lack modern safety features (they are fire prone) and are uncomfortable (no air conditioning). The health benefits of electric mail trucks would be significant for both the drivers and the communities they serve. As the gas-guzzling vehicles weave through densely populated neighborhoods, they spew toxic emissions with every exhaust-belching stop and start. Theoretically, the electric switch shouldn't be difficult. Mail carrier routes average only 20 miles a day. That means even outdated lead-acid battery technology would provide adequate range. The trucks are also parked in the same spot every night for reliable charging. But Postmaster General Louis DeJoy, a Trump appointee, has historically said electric vehicles simply cost too much. That's a familiar refrain for an agency that has toyed with EVs for over a century. It seems, however, USPS is finally making a U-turn.
