National clean freight truck and bus standards

Clean truck standards help ensure that our nation's fleet of heavy-duty trucks and buses use dramatically less fuel, cut climate and other harmful pollution, and save both truckers and consumers money

EPA has proposed new clean truck standards for model years 2027 and beyond. President Biden directed EPA to consider the role zero-emitting vehicles (ZEVs) can play in these rules. Swiftly deploying ZEV trucks and buses is feasible, will help grow well-paying American jobs, and is critical to reducing harmful pollution in communities across the country, especially those hardest hit by urban trucking pollution.
A new study performed for EDF by Roush Industries finds that most market segments of electric trucks and buses will reach upfront cost parity with diesel vehicles by 2027. For all segments studied, the total cost of owning a ZEV purchased in 2027 will be less than a diesel counterpart over the life of the vehicle.

Transition to ZEV trucks and buses

Our nation must adopt air pollution standards to ensure that all new sales of medium and heavy-duty trucks and buses are ZEVs by 2040. We must also eliminate tailpipe pollution from new vehicles that operate in urban and community applications by 2035 or earlier.
According to an EDF analysis, national standards that achieve 100 percent new ZEV sales by 2040 would:

  • Avoid 224 million metric tons of greenhouse gas (GHG) emissions every year by 2040 and eliminate tailpipe CO2 emissions from the heavy-duty fleet by 2050
  • Reduce ozone-forming nitrogen oxides (NOx) pollution by more than 450,000 tons and harmful particulate pollution by nearly 9,000 tons every year by 2040
  • Prevent as many as 2,600 premature deaths and 140,000 lost workdays each year by 2040 and as many as 57,000 premature deaths in total through 2050
  • Provide our nation with up to $485 billion in health and environmental benefits. 

Manufacturers and fleets are committed to ZEVs

Momentum for the transition to ZEVs is quickly building in the medium and heavy-duty sector. Manufacturers are committing to a zero-emission future and investing billions of dollars to bring ZEVs to market.

  • Ford, the world’s largest manufacturer of cargo vans, has already begun shipping its all-electric transit cargo van for last mile urban deliveries, a move backed with a multi-billion dollar investment.
  • Daimler announced a target that all new trucks and buses in North America will be carbon neutral by 2039 and has allocated $85 billion toward the goal.
  • Volvo, owner of Mack Trucks, has said it aims to have 100% of its new truck and bus sales be fossil free by 2040.
  • General Motors, which announced plans to eliminate tailpipe pollution from its passenger cars by 2035, plans to sell ZEV versions of all HD trucks by 2035.
  • Navistar is investing $275 million in a San Antonio plant that will produce diesel and electric trucks, supporting 650 new jobs.
  • Lion Electric will build the nation’s largest all electric medium- and heavy-duty vehicle manufacturing plant in Illinois, investing at least $70 million.

Shippers and trucking fleets across the country are also embracing ZEV trucks. EDF has created an Electric Fleet Deployment and Commitment List to track their deployments and commitments. A few examples include:

  • Walmart is targeting zero global operational emissions by 2040, including electrifying all long-haul trucks. It has ordered 5,000 BrightDrop electric vehicles.
  • FedEx has pledged a 100% electric pick-up and delivery fleet and carbon-neutral operations by 2040.
  • Amazon has ordered more than 100,000 electric delivery trucks from Rivian.
  • FedEx has reserved 2,000 GM BrightDrop cargo vans with plans to add up to 20,000 more.
  • Merchant Fleet expanded its order of BrightDrop electric vehicles to 18,000.
