EPA Approval and Regulatory Stability
In March, the U.S. Environmental Protection Agency (EPA) approved California’s proposal to mandate an escalating number of zero-emission heavy-duty trucks. To provide manufacturers with ample time for compliance, the CARB has committed to four years of lead time and at least three years of regulatory stability before imposing additional demands.
Industry Commitment to Zero-Emissions Technology
The “Clean Truck Partnership” comprises well-known companies in the sector, including Cummins, Daimler Truck North America, Ford Motor, General Motors, Hino Motors, Navistar, Stelantis, and Volvo Group North America. These industry leaders have pledged to meet California’s vehicle standards, which necessitate the sale and implementation of zero-emissions technology within the state. Importantly, this commitment remains intact regardless of any challenges to California’s authority to implement stringent emissions regulations.
Commenting on the partnership, Governor Gavin Newsom stated, “Today, truck manufacturers are joining our urgent efforts to combat air pollution, demonstrating to the rest of the nation that we can simultaneously reduce harmful emissions and build a thriving economy for the future.”
NOx Emission Regulations
In March, the EPA declined California’s request to establish new regulations on NOx and particulate matter emissions for 2024 and future medium- and heavy-duty engines and vehicles. In response, the CARB has agreed to modify certain aspects of the 2024 NOx emission regulations. Manufacturers will be required to provide offsets to maintain California emission targets.
EMA President Jed Mandel commended the agreement, stating, “Through this agreement, we have established a unified national standard for nitrogen oxide emissions, secured the necessary lead time and stability for manufacturers, and agreed upon regulatory changes that will ensure a continued supply of commercial vehicles.”
The EPA has expressed its support for the agreement and looks forward to reviewing the specifics of the partnership.
