Exclusive: DfT refuses to publish emission figures, which campaigners say could make new road projects unviable
The UK government is refusing to release the carbon emission figures behind its transport decarbonisation plan, which campaigners say could make proposed road schemes financially unviable.
The Department for Transport (DfT) is blocking academics from seeing the figures, which include data on how much car use would have to be reduced in order to reach net zero commitments.
