When Boris Johnson laid out his ten point plan for the UK’s “Green Industrial Revolution” yesterday, its most eye-catching policy was the proposal to ban the sale of new petrol and diesel cars and vans by 2030. The ban had been on the cards for 2040 but has now been brought forward by a decade. A report by the Climate Change Committee saying that the UK had to switch-over to electric vehicles by 2032 in order to meet its target of net zero carbon emissions by 2050 perhaps played a role in informing this change of policy. However, experts have also warned that making the transition will not be easy.
