In May, both houses of Congress passed a resolution that nullifies the Environmental Protection Agency’s (EPA) approval of the wavers granting California the ability to implement vehicle emission standards for light and heavy-duty vehicles beyond the national standards. Once signed into law, the resolution means that California can no longer enforce its ban on internal combustion engine (ICE) vehicle sales from 2035. The block will not only slow California’s electric vehicle (EV) transition, but the transition of all the other states that have since adopted California’s regulation. The slower rate of emission reductions that will ensue from the ruling will lead to California’s carbon price doubling from initial forecasts by 2030.
