The Truck and Engine Manufacturers Association has sued the California Air Resources Board, saying the agency has not provided enough lead time for truck and engine makers to meet its latest emission standards due to go into effect in 2024.
On Dec. 22, 2021, CARB adopted the Heavy-Duty Engine and Vehicle Omnibus Regulation, a package of stringent emission standards, test procedures, and other emission-related requirements applicable to new heavy-duty on-highway engines and vehicles sold in California. The Omnibus Regulation requires heavy-duty engine and vehicle manufacturers to comply with the new standards on Jan. 1, 2024, giving manufacturers only two years of lead time.
The federal Clean Air Act allows California to establish its own emissions standards, EMA said, provided California meets certain requirements — including providing heavy-duty on-highway engine and vehicle manufacturers four full model years of lead time.
The Omnibus Regulations would require, among other things, that heavy-duty engine manufacturers develop and deploy new technology to reduce nitrogen oxide (NOx) emissions initially by 75% and particulate emissions by 50%, demonstrate emissions compliance on entirely new test cycles, and ensure emissions compliance for certain “Class 3” heavy-duty engines using new durability test procedures out to an extended “useful life” range of 150,000 miles instead of 120,000 miles, explains the lawsuit filing. It would require engine manufacturers to redesign, test and build their engines to comply with all of those new requirements starting with Model Year 2024, which begins, at the latest,—on Jan. 1, 2024.
“Truck and engine manufacturers are proud that today’s modern engines reduce harmful emissions to near zero levels, and we are committed to building still cleaner products,” said EMA President Jed Mandel in a news release. “But CARB must provide manufacturers the minimum four years of lead time mandated by Congress…. This lawsuit is simply to ensure that CARB follows all of the prescribed rules — one of which is intended to maximize the likelihood of the smooth and successful implementation of new emission standards.”
Environmental Groups: ‘A New Low’
Environmental groups were quick to criticize the suit. They claim that truck and engine makers that are part of EMA are being hypocrites, as several prominent executives have publicly called for faster action to meet global emissions targets.
A blog post on the website of the Natural Resources Defense Council characterized the action in a headline, “Truck Manufacturers Sue to Continue Polluting,” accompanied by a photo of an old rig belching black smoke in 2014.
“EMA’s lawsuit is a direct attack on our communities, lungs, and the environment,” wrote Patricio Portillo, senior advocate for NRDC’s Climate & Clean Energy Program. “It’s also a new low for EMA, a trade association comprised of vehicle and engine manufacturers who have made public statements about their desire to clean up vehicle pollution…. This lawsuit is evidence that no matter the public statements, truck manufacturers will never clean up their act unless forced to by vehicle emission standards.”
In an email, a spokesperson representing a group environmental organizations, including NRDC, said, “These standards will literally save lives. American Lung Association's latest State of the Air report finds that California cities continue to top the country's list of most polluted. Diesel death zones situated arounds ports and warehouses are some of the clearest examples of environmental racism in the state thanks to decades of redlining. These communities are desperate for relief.
“Adding insult to injury, California gives EMA members — e.g. Volvo, Daimler, Cummins — hundreds of millions of dollars to support clean truck R&D.”
Other groups represented by this email in addition to NRDC include the Center for Community Action and Environmental Justice, the People's Collective for Environmental Justice, East Yard Communities for Environmental Justice, Central California Asthma Collaborative, BlueGreen Alliance, and Earthjustice’s Right to Zero campaign.
