The Times, 22 November 2017:
Sir, It is disingenuous to argue against a tax on diesel fuel merely because some of the latest models have lower nitrogen oxide emissions than cheaper petrol-driven vehicles. The main threat to health from the combustion of fossil fuels is small particulates, and historically diesel vehicles have produced far more of these than petrol-driven engines. The purpose of a diesel tax is to limit the use of the most polluting vehicles, but we still need a new Clean Air Act whose aim should be the replacement of all fossil fuel-dependent vehicles with clean methods of transport. Furthermore, this needs to happen well before the government’s proposed starting date of 2040.
