Darling and Howard back call for post-Brexit carbon tax

Policy Exchange report calls for steadily rising levy to help tackle climate change

Companies selling fossil fuels in Britain should face a steadily rising carbon tax to tackle climate change after Brexit, according to the former Labour chancellor Alistair Darling and the Conservative party grandee Michael Howard.

In a cross-party campaign to ensure the government sticks to its commitment to cut carbon emissions after Britain leaves the EU, the two politicians said a tax should be introduced as soon as reasonably possible.
