The UK Government wants to end the sale of new petrol and diesel vehicles by 2040 and has announced a £400 million fund to boost electric vehicle charging infrastructure, including more than doubling the number of charging points across the UK to 5,000.
Among the new electric concepts on show in Tokyo are the Nissan Ariya and the Mitsubishi Mi-Tech – which includes four electric motors.
The use of sustainable materials has also been highlighted by Mazda, which unveiled its MX-30 that includes seats made from recycled bottles and heritage cork used in the central console.
