Today’s the last day of the California legislative session. It gets hectic in Sacramento this time of year, but here are two bills I’m paying attention to that could help reduce air pollution and global warming emissions from heavy-duty vehicles.
As a reminder, heavy-duty vehicles make up just 7 percent of vehicles in California but disproportionately contribute to global warming emissions and air pollution, contributing 20 percent of global warming emissions from the transportation sector, for example. And as we work to improve public health, we must also remember that communities of color are disproportionately exposed to pollution through proximity to roadways, ports, warehouses, and other sources of emissions.
Cleaning up state-owned trucks and buses
That’s what Assembly Bill 739 by Assemblymember Ed Chau would do. This bill sets a target for zero-emission trucks and buses purchased by the state: 15 percent of purchases made in 2026-2030 and 30 percent of purchases made in 2031 and later. This is an achievable target with eight years’ worth of technology development and agency planning to enable its implementation.
The target would apply to vehicles with gross vehicle weight ratings (the maximum weight at which a fully loaded vehicle is rated to operate) above 19,000 lbs. For a sense of scale, think transit buses, large U-Haul-type trucks, garbage trucks, etc. The bill only applies to state-owned vehicles, which includes everything from buses at the Cal State universities to work trucks operated by the Department of Parks and Recreation and Caltrans. The purchase goals do not apply to vehicles with special performance requirements necessary for public safety, such as fire trucks operated by the Office of Emergency Services.
This bill walks the talk. There’s been a lot of planning and workshops on how to get zero-emission trucks and buses on the road in California, from the Sustainable Freight Action Plan to standards for trucks, buses, and airport shuttles. This bill holds the state fleet to a similar standard.
It is important to note that the 15 percent and 30 percent targets in this bill apply only to purchases, not the overall composition of the state’s fleet. Suppose a given type of vehicle typically lasts 14 years. This means roughly 7 percent of those vehicles are turned over each year. A 15 percent purchase target in this case corresponds to 1 percent of the total fleet (15 percent of 7 percent).
There are many zero-emission heavy-duty vehicles already commercially available today and more on the way. Cummins recently unveiled an electric truck and Tesla will reveal its electric truck with a 200-300 mile range at the end of next month. Many other major companies have also signaled their interest in zero-emission trucks, including Daimler, Peterbilt, and Toyota.
Large scale funding for clean vehicles
That’s what recent amendments to Assembly Bill 134 (the budget bill) would do. The legislation proposes $895 million in funding for clean vehicles using revenue from the state’s cap and trade program. If that sounds like a lot of money, it is compared to previous years ($680 million for the last four years combined). But it’s not compared to the level of action needed for the state to meet its air quality and climate goals.
Oversubscribed incentive funding programs that offset the upfront purchase cost of electric trucks, buses, and cars for businesses and consumers receive much-needed funding in this bill, including $180 million for the Hybrid and Zero-Emission Truck and Bus Voucher Incentive Project (HVIP). This program provides rebates for medium- and heavy-duty vehicles, with zero-emission trucks and buses receiving larger incentives than combustion technologies. The $35 million in HVIP designated for zero-emission transit buses alone could allow half of the roughly 700 buses purchased in California over the next year to be battery electric vehicles.
The budget bill also includes $140 million for the Clean Vehicle Rebate Program (CVRP), which provides consumers with rebates for plug-in hybrid electric, battery electric, and fuel cell electric passenger cars. This program has helped put over 200,000 clean cars on the road in California since 2010. There’s a lot more in the budget bill for clean vehicles ($575 million), but the CVRP and HVIP programs are ones UCS has been especially involved with.
These two bills are very different in scale – AB 739 applying to a fraction of state-owned vehicles and the budget bill providing incentives to businesses and consumers for vehicles across the light-, medium-, and heavy-duty classes. But to reach the end goal of clean air for all Californians and dramatically reduced climate emissions, we need actions that span all scales.
