The carbon intensity of newly registered passenger vehicles is measured in grams of CO2 emitted per kilometre driven. The last three years of data held on the fleet wide average CO2 emissions of newly registered petrol and diesel cars in the UK shows an increase over time. Excluding zero emission vehicle registrations, the provisional average for new petrol cars only in 2020 was 140.0 grams of CO2 per kilometre, 143.3 grams of CO2 per kilometre in 2021 and 143.0 grams of CO2 per kilometre in 2022. The provisional average for new diesel cars only in 2020 was 153.8 grams of CO2 per kilometre, 161.0 grams of CO2 per kilometre in 2021 and 164.0 grams of CO2 per kilometre in 2022. When considering the overall fleet of new cars, including zero emission, the average CO2 intensity has decreased over the last three years. The provisional average for 2020 was 126.6 grams of CO2 per kilometre, 118.5 grams of CO2 per kilometre in 2021 and 110.8g grams of CO2 per kilometre in 2022.

The Government\u2019s 2021 Transport Decarbonisation Plan (TDP) set out 78 commitments to support decarbonisation of the UK\u2019s transport system by 2050. Since then, significant progress has been made with over a third of these commitments having been delivered or exceeded within three years. For example, the Zero Emission Vehicle (ZEV) mandate entered into force in January 2024 - the world\u2019s most ambitious national level regulation of its kind. We regularly review our transport decarbonisation policies to ensure they are on track and are committed to publishing our progress and reviewing our net zero pathway at least every five years.<\/p>
