Reducing carbon emissions from roads, railways and shipping requires implementing a range of solutions simultaneously. As far as cars are concerned, cutting the number of journeys altogether (by making it easier for people to walk and cycle and improving public transport), changing the fuel in vehicles and making the most of those vehicles already on the road must all play a part. None of these solutions are sufficient on their own.
In 2030, the sale of new diesel and petrol passenger cars will be outlawed in the UK. The future of passenger motoring will be electric. But recent problems supplying parts and the high carbon cost of manufacturing electric vehicles could delay the climate benefits of this transition.
