Air Pollution

Recent decisions by the Supreme Court and the EPA appear to favor California's 2035 ban on gas-powered cars and trucks, but another important lawsuit, a Republican-dominated Congress and President Donald Trump are still there to challenge it.

The US EPA granted California’s waiver, which the incoming Trump administration is likely to try to overturn in the courts. The state's zero-emission vehicle mandates have been the driving force behind California's progress in cleaning up dangerous air pollutants.

The Supreme Court justices agreed to review whether oil companies have standing to try to overturn a federal waiver for a California clean-car rule that ramped up electric car sales. The standards are the cornerstone of California's efforts to clean its air and combat climate change.

The Biden administration is awarding Inflation Reduction Act money to help clean the air before President-elect Trump takes over.

California has an aggressive mandate for zero-emission trucks, which are powered by electricity or hydrogen. But trucking companies face big obstacles — and people are still breathing dangerous diesel exhaust.

Proposed amendments to the Low Carbon Fuel Standard program fall short of the goals of transparency, equity and responsible policymaking, says a member of the California Air Resources Board.

Bikers — many of whom love their noisy combustion engines — say zero-emission motorcycles aren’t ready for long-distance rides. Motorcycles emit an “outsized portion” of smog-causing pollutants.

California should protect families and save billions in public funds instead of allowing oil and gas corporations to squander the money on carbon capture projects.
