Towards a Zero Carbon Vision for UK Transport

This 2010 report by the Stockholm Environment Institute explores pathways for the United Kingdom to achieve a zero-carbon transport system by 2050. It compares a Business-as-usual (BAU) scenario with a Maximum Impact (MI) scenario, quantifying the potential CO2 reductions from spatial planning, fiscal measures, behavioural changes, and technological shifts across road, rail, aviation, and shipping sectors.

• Under the Maximum Impact (MI) Scenario, the UK transport sector could achieve a 76 per cent reduction in CO2 emissions by 2050 compared to the Business-as-usual (BAU) Scenario, or a 68 per cent reduction relative to the BAU baseline year emissions.
• Road transport can achieve complete carbon neutrality by 2050 through a combination of a 75 per cent reduction in demand—driven by spatial, fiscal, and behavioural measures—and a transition to plug-in electric vehicles (PEVs) and hydrogen fuel cell vehicles powered by a decarbonised electricity supply.
• The re-introduction of a fuel price escalator (FPE) at 5 per cent per annum above inflation from 2010 to 2050 is identified as the measure with the greatest impact on reducing road transport demand, resulting in a 600 per cent increase in fossil-fuel hydrocarbon costs.
• Rail transport can reach zero CO2 emissions by 2050 through the complete electrification of the UK rail network and the use of a 100 per cent carbon-neutral electricity supply.
• Aviation emissions in the MI Scenario are reduced by 56 per cent compared to the 2050 BAU scenario. The most effective reductions come from demand-reduction strategies, including air fare increases, the absence of new runways at Heathrow and Stansted, and modal shifts to rail and video conferencing.
• Shipping emissions can be reduced by 49 per cent in the MI Scenario through a combination of operational changes (such as slower speeds and voyage optimisation), new hull and propeller designs, cleaner fuels, and shore-side electricity.
• The 24 per cent shortfall in achieving a total zero-carbon transport system by 2050 is entirely attributed to the remaining emissions from the aviation and shipping sectors, which are more technically challenging to decarbonise than road and rail.
• The transition to a zero-carbon transport system is expected to provide significant co-benefits, including the elimination of traffic-related air quality problems (reducing the 16,000 annual vehicle-related deaths in the UK), reduced noise pollution, and improved social mobility for excluded groups.
