The Trump administration has dealt a significant blow to California’s efforts to reduce greenhouse gas emissions from its truck fleet. The Federal Trade Commission (FTC) recently announced an agreement with four major truck manufacturers, including Daimler and Volvo, stating that California’s zero-emission sales targets are “unenforceable.” This move effectively nullifies the state’s 2023 deal with these companies to abide by California’s stricter emissions standards.
California signed a voluntary agreement with nine truck manufacturers in 2023, aimed at ensuring they met the state’s more stringent emissions requirements. However, after President Trump returned to power, the state’s special authority to set stricter-than-federal vehicle rules was revoked. The four truck makers have now filed a lawsuit arguing that California’s regulatory framework is incompatible and hostile, making it impossible for them to comply.
Environmentalists argue that this argument lacks merit, as the Clean Truck Partnership was designed precisely for such situations. “The Clean Truck Partnership was exactly for a moment like this,” said Adam Zuckerman, senior clean vehicles campaigner with Public Citizen’s Climate Program.
Former CARB official Craig Segall expressed concerns about the potential impacts on California’s pollution-reduction efforts. While some electric trucks will still be sold, it is likely to be inadequate compared to what was originally planned.
California has not yet lost all its leverage in this matter. Stellantis, one of the companies that signed the original agreement, reaffirmed its commitment to following California’s EV sales rules after President Trump revoked a critical EPA waiver. The state may still offer incentives for companies and fleets purchasing electric trucks or exclude those who don’t.
With recommendations from state agencies expected soon, California could take swift action to bolster the EV market. Governor Newsom’s executive order in June directed CARB to develop new regulations and provide preferential treatment to companies working towards electrification goals.
