Question to the Department for Transport:

To ask His Majesty's Government what assessment they have made of the contribution of the aviation sector to emissions in the UK, and of the impact on the UK's ability to meet climate targets.

According to the latest final UK greenhouse gas emissions statistics published by the Department for Energy Security and Net Zero, greenhouse gas emissions from domestic and international civil aviation in 2023 totalled 34.4 million tonnes of carbon dioxide equivalent (MtCO2e). This was 8 percent of total UK greenhouse gas emissions.

The government is making great strides in transitioning to greener aviation, including by introducing the Sustainable Aviation Fuel (SAF) Mandate and introducing the SAF Bill to implement the revenue certainty mechanism.

The government makes regular assessments concerning the impact of aviation emissions on climate targets. A Carbon Budget Delivery Plan will be published later this year, detailing policies to decarbonise all sectors, including aviation, covering the carbon budget 4 - 6 period (2023 – 2037).
