The EPA and the White House Council on Environmental Quality sent letters to the Postal Service on Wednesday that urge it to reconsider plans to buy mostly gas-powered vehicles and conduct a new, more thorough technical analysis. The EPA also asked the Postal Service to hold a public hearing on its fleet modernization plans, a request the agency had rejected when California regulators made it Jan. 28.
“The Postal Service’s proposal as currently crafted represents a crucial lost opportunity to more rapidly reduce the carbon footprint of one of the largest government fleets in the world,” wrote Vicki Arroyo, the EPA’s associate administrator for policy.
Transportation is the largest single source of greenhouse gas emissions in the U.S., and even rising sales of electrical vehicles have yet to make a dent. Electric vehicle proponents had hoped the Postal Service purchase would provide a boost for the industry.
