The British government will ban new petrol and diesel cars from 2040 as part of its clean-air strategy.
The British government has announced diesel vehicles, the main cause of pollution in London, will be banned in 23 years, from 2040.
France has the same target as Britain, while Norway's is just eight years away, in 2025.
So could Australia follow?
Analysts are divided.
But there are challenges with the size of Australia, and the fact not many people are buying electric cars.
Last year, almost 1.2 million new cars were sold in Australia.
More than 1.1 million were petrol or diesel.
Only 12,800 were hybrid or electric -- just 1 per cent of the market.
The SBS Korean program has more.
