December 2025: Electric trucks, buses round-up
Medium- and heavy-duty electric vehicles are hitting the road in 2025, and we’ve collected last month’s most exciting news. After another record year of zero-emission truck deployments in 2024, this year promises more big announcements. This monthly blog series will showcase the biggest orders and deployments of zero-emission trucks happening around the country.
December announcements include an electrification from the United States Postal Service, and efforts to improve air quality and sustainability in Hawaii.
USPS continues its electric van rollout, with 66,000 EVs joining the fleet by 2028
The United States Postal Service reaffirmed its commitment and provided an update on their electric vehicle transition. The USPS previously announced an order for 45,000 next generation electric vehicles provided by Oshkosh Corporation. As of December 2025, over 600 of these vehicles have been put into service across the United States, along with 2,000 Ford E-Transit vehicles. The USPS aims to have all electric vehicles deployed by 2028.
DHL adds first Tesla Semi to fleet after successful pilot
DHL Supply Chain took delivery of its first Tesla Semi electric Class 8 truck after a successful pilot program. The company currently operates several electric Class 8 trucks from different suppliers across their fleet. Additional Tesla deployments are planned for 2026 as the truck becomes more widely available. DHL aims to achieve a 66% transition to zero-emission trucks for last-mile delivery by 2030.
New electric buses set to roll out on Maui
Maui County announced that four new electric buses will enter service across the island in the new year. Drivers are currently being trained on the new buses that offer reduced noise, emissions and are a major step towards the clean transportation goals set by the county transportation department. The county hopes to integrate zero-emission buses into additional routes going forward.
Now is a critical time for fleets to invest in medium- and heavy-duty electric trucks. These vehicles improve public health and help combat the climate crisis by reducing greenhouse gas emissions and air pollution. Unlike traditional diesel-powered trucks, electric trucks produce no tailpipe emissions, which significantly cuts down on health-harming pollution. Adoption represents a key step toward a more sustainable and resilient transportation industry.
Check back here next month to see a collection of the most exciting zero-emission vehicle announcements from January. In the meantime, check out EDF’s Electric Fleet Deployment & Commitment List to track announcements as they happen in real time, and view all December announcements.
