Theresa May wants UK roads to be free of petrol and diesel cars by 2040.
The Prime Minister is to announce a £106 million funding boost for research into the development of zero-emission vehicles so that Britain can "lead from the front" when it comes to green technology.
Speaking at the inaugural Zero Emission Vehicle Summit in Birmingham, she said: "I want to see Britain, once again, leading from the front and working with industries and countries around the world to spearhead change.
"That is why I have set this country an ambitious mission. To put the UK at the forefront of the design and manufacturing of zero-emission vehicles and for all new cars and vans to be effectively zero-emission by 2040."
