Air Resources Board

Under the new scoping plan, California would almost eliminate oil and shift to renewable sources. But where’s the update on the controversial polluting-trading market known as cap and trade?

If enacted this summer, California’s mandate — the first in the world — would increase sales of electric or other zero-emission cars to 35% in 2026, and prohibit new gasoline or diesel cars by 2035.

The Air Resources Board proposed requirements for zero-emission vehicle sales start unnecessarily low in 2026.

To limit further damage from climate change and air pollution, we have to ensure all cars on the road in 2045 are free of emissions.

The California Air Resources Board will vote on regulations to phase out diesel-fueled units that would be replaced by zero emission units.

A look at one polluted region — the LA/Long Beach port communities — targeted for clean-air priority under California’s environmental justice law.

California's environmental justice law is supposed to clean the air for 15 hot spot communities, home to almost 4 million people. But after more than 4 years and $1 billion, it’s still impossible to say whether it's worked.

A landmark California environmental justice law was supposed to clean the air in 15 key communities, but it's hard to say if it's worked.

California’s air board enacted two first-of-their-kind smog rules for trucks and lawn equipment. They’ll cost billions but cut tons of emissions.

California will ban most new gas-powered lawn equipment starting in 2024, but landscapers and gardeners warn the transition will cost them money and jobs. Industry officials say the technology isn’t ready for commercial use and called a $30 million incentive program for small operators inadequate. One state lawmaker who co-authored the bill says he’s open to more funding.
