This week, the Environmental Protection Agency is hearing from scientists, mothers, healthcare professionals, public health and environmental advocates – including EDF – and many others who submitted comments in support of California clean truck standards.

As EPA works toward finalizing federal heavy-duty emission standards proposed earlier this year, the agency has been accepting public comment on its notices considering Clean Air Act preemption waivers for California clean truck standards, including the Advanced Clean Trucks and Heavy-Duty Omnibus NOx (low-NOx) standards. Several other states have already adopted these standards in recent years to reduce health-harming pollution from new freight trucks and buses. The ACT requires an increasing percentage of new trucks and buses to be zero-emission through 2035, while the low-NOx standards aim to reduce nitrogen oxides from new diesel trucks.

Taken together, these protections will prevent almost 5,000 premature deaths, save California billions of dollars in health care costs and create thousands of new jobs by 2035. But the Truck & Engine Manufacturers Association — a trade group of the nation’s largest engine manufacturers, including Volvo and Daimler — has opposed these safeguards at the state and federal level, and is now challenging in court California’s ability to implement the low-NOx emission standards.

There is no single fix to the climate, air quality, political and economic challenges facing California, but the state’s early action to electrify its fleet of medium- and heavy-duty vehicles is one example of smart policy that can move us in a positive direction. As California’s legislative session concludes in August, lawmakers and the California Air Resources Board should take the next steps to implement the electric transportation transition with tools that are right at their fingertips.

Nationally, the transportation sector is the largest source of climate emissions and a primary contributor to local air pollution and the negative health and economic impacts that go along with it. Medium- and heavy- duty vehicles – the trucks and buses that move our goods and people – make up a small portion of total wheels on the road, but they produce an outsized portion of all emissions. In California, MHD vehicles make up just 6% of vehicles on the road, but produce 72% of the state’s health-harming nitrogen oxide emissions and 21% of all transportation climate emissions. Transitioning these vehicles to zero-emission models would make a big difference for air quality and the manufacturing economy, a sector where California is becoming a leader.

Update: The California Air Resources Board is hosting a public work group meeting on May 4 at 1:00pm PST to discuss the new Proposed Zero Emission Loan Pilot within the Truck Loan Assistance Program. Stakeholder input is needed to determine how loans should work under SB372. There will be future meetings on other elements of SB372 to come. Please click here for more information.

Last year the California State Legislature passed Senate Bill 372, an important new bill that will help finance the next generation of zero-emission trucks. The law directs the California Air Resources Board and the California Pollution Control Financing Authority in the State Treasurer’s Office to offer financial and non-financial tools to help owners of medium- and heavy-duty trucks and buses pay for the costs of replacing their diesel-fueled fleets with cleaner, ZEV alternatives.

This bill is meant to bring key stakeholders to the table — environmental justice groups, truck manufacturers, fleets, financiers, nonprofit organizations and others — to find the solutions that will work for fleets to transition to zero-emission MHD vehicles.

Based on conversations EDF had with fleets, financiers and others, about what they need to invest in ZEV trucks, we discovered that it is critical to bring stakeholders to the table in order to find out what works, recognizing that multiple options are needed, because when it comes to fleets, one size does not fit all.
