California Governor Gavin Newsom has signed an executive order that will ban the sale of new cars that are gasoline-powered, beginning in the year 2035.

"This is the most impactful step our state can take to fight climate change," Newsom said in a statement. "For too many decades, we have allowed cars to pollute the air that our children and families breathe. You deserve to have a car that doesn't give your kids asthma… Cars shouldn't melt glaciers or raise sea levels threatening our cherished beaches and coastlines."

He is also asking the state legislature to stop issuing new permits for fracking by 2024.

California is the largest market for cars and trucks in the U.S., accounting for 11 percent of sales. Other states often follow California's lead on emissions regs.

All this comes right before an election in which the incumbent, Republican President Donald Trump, has tried to prevent California from making electric-vehicle sales a requirement, while challenger Joe Biden, the Democratic nominee, has said he'd pour money into the quicker adoption of EVs.

Fifteen countries, including Britain, have introduced similar measures.

Newsom wants the California Air Resources Board (CARB) to work on regulations that will make sure 100 percent of in-state new car and truck sales will be of zero-emission vehicles, which he claims will cut greenhouse-gas emissions by 35 percent.

The board is further expected to require that medium- and heavy-duty vehicle emissions will also be zero, where feasible, by 2045.

California residents would not be prevented from owning gas-powered cars under the order, nor would they be prevented from selling such vehicles on the used-car market.

Newsom has said the state needs to increase its efforts to fight greenhouse gasses and climate change in the wake of devastating wildfires, and the state, along with almost 24 others, has been suing the Trump administration, which wants to takeaway California's ability to set its own pollution rules and to rollback nationwide emissions standards.
