WASHINGTON (AP) — The Biden administration is restoring California’s authority to set its own tailpipe pollution standards for cars, reversing a Trump administration policy and likely ushering in stricter emissions standards for new passenger vehicles nationwide. A waiver approved Wednesday by the Environmental Protection Agency allows California to set tough emissions rules for cars and SUVs. The state also will be allowed to impose mandates for so-called zero-emission vehicles that do not contribute to global warming. At least 15 states and the District of Columbia have signed on to California’s vehicle standards, which are stricter than federal rules and are designed to address the state’s severe air pollution problems.
