Countries around the world are racing to achieve targets on the ban of new petrol and diesel cars - but they are hitting stumbling blocks, meaning some are pulling back on their commitments.
Although global sales of electric cars are rising, some countries are struggling to persuade drivers to make the switch. Reasons given include insufficient or unsuitable charging points, and the price tag: criticism is often put to governments that the shift to electric cars is hardest for the least well off.
In this edition of Business Daily, Rick Kelsey looks at one country which is well ahead of the rest: Norway. The country's aim is that all new car sales in 2025 will be of electric vehicles - a plan being supported by financial incentives and policy changes.
He also speaks to business leaders in the car industry, including a man known as "the Godfather of EV", to find out what's needed if countries are to phase out internal combustion engines.
