USPS fulfills top Biden climate goal with deployment of 66,000 electric delivery trucks " The shift toward electric vehicles, which follows pressure from environmental groups and a funding boost from the Inflation Reduction Act, will see the agency purchase at least 60,000 “Next Generation Delivery Vehicles,” of which at least 45,000 will be electric. By 2026, the US Postal Service plans to purchase zero-emissions delivery trucks almost exclusively."
