The rules would hold pollution magnets like warehouses, ports and railyards accountable for the trucks and ships they attract.

A new conservancy will oversee work to improve vegetation, water quality and natural habitat in the Salton Sea. Will nearly half a billion dollars in projects be enough?

Experts don’t know how much gas prices may rise from the revised California climate program, which tightens standards and gives incentives for low-carbon fuels. The board ordered an annual review of the cost impacts.

The state’s environmental tool skews which communities are designated as disadvantaged, researchers say. Some immigrant neighborhoods could be left out, while other groups are overrepresented.

The federal standard will likely throw new California counties out of compliance — and put even more pressure on the LA basin and San Joaquin Valley to clean the air.

In a worldwide first, California’s air board unanimously moves to end diesel’s decades-long stranglehold on the economy. Truckers predict chaos, while communities near ports, freeways celebrate cleaner air.

New initiatives have been added to California’s draft scoping plan, including climate-friendly homes, offshore wind and cleaner airplane fuels.

The Supreme Court’s decision to limit federal environmental protection rules will have little-to-no effect on California’s carbon-reduction policies, according to experts — and state leaders say they are doubling down on their climate commitment.

California’s climate change plan fails to provide substantial evidence that capturing carbon will meet ambitious greenhouse gas goals, critics say. The plan “does California a disservice,” one state advisor said.

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.
