The UK Government is falling far short of its own rail decarbonisation targets, and it is making insufficient progress on its key UK rail decarbonisation commitments. These are the findings of a detailed quantitative analysis, carried out by industry insiders. Nearly two years on from the publication of the Government’s Transport Decarbonisation Plan (TDP) which set out how transport would achieve net-zero carbon by 2050, the Railway Industry Association (RIA) has reviewed all the commitments made in the TDP and measured them against public announcements up to May 2023.
