California governor signs executive order to ban gas-powered cars and trucks by 2035. He would also like to establish regulations to require zero-emission vehicles by 2045. If you ban gas powered vehicles in by 2035 that should be pretty easy?
The transportation "sector" is responsible for over half the pollution according to Governor Newsom. The most toxic of the air pollution is centered around Los Angeles.
“This is the most impactful step our state can take to fight climate change,” Newsom said while announcing the order. “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.”
There is some good news. A UN report released in mid-September said carbon emissions declined this year because of coronavirus. They've also found that breathing contributes to coronavirus but had no suggestions on how to remedy that situation.
