Medium- and heavy-duty trucks are major contributors to greenhouse gas emissions and air pollution. Yet California’s policies to phase out fossil fuel-powered trucks in favor of zero-emission models have been undermined by recent federal actions, including a congressional vote to terminate California’s mandate on truck makers to produce zero-emission models and a rollback of many federal tax incentives for these vehicles. Furthermore, in January 2025 the state withdrew from U.S. EPA consideration its proposed mandate for major fleets to purchase zero-emission trucks.
To identify new state policies to increase demand for zero-emission trucks, UC Berkeley Law’s Center for Law, Energy and the Environment (CLEE) and the UCLA Law Emmett Institute on Climate Change and the Environment are releasing the new report Driving Demand: Solutions To Increase The Market for Heavy-Duty Zero-Emission Vehicles. Based on a convening of a select group of stakeholders and experts, the report offers recommendations for state and federal policy makers, as well as industry leaders.
