U-M researchers challenge USPS EV environmental study

Green Car Congress

When anticipated improvements to electric vehicles and future electrical-grid decarbonization are factored in, a fully electric USPS delivery fleet would result in up to 63% lower greenhouse gas emissions than the agency estimated, over the lifetime of the fleet. An all-electric fleet would reduce lifetime greenhouse gas emissions by 14.7
