Petrol Car Bans

Five years earlier than previously planned, as part of what Prime Minister Boris Johnson is casting as a "green revolution", Britain will ban the sale of new petrol and diesel cars and vans from 2030, to cut emissions to net-zero by 2050.
In total the plan would mobilise 12 billion pounds ($16 billion) of government money, with as much as three times that amount coming from the private sector, and create and support 250,000 highly skilled green jobs by 2030, Johnson said.

The Californian Governor Gavin Newsom has announced that by executive order new cars and light trucks that are powered by gasoline will be prohibited to be sold starting in 2035. This does not include cars that are already on the road at that time. Those will continue to be legal and can be resold.
Newsom stated that "this is the most impactful step our state can take to fight climate change".
