Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, in 1990, what was the contribution in parts per million of CO2 emissions from the UK into the atmosphere (a) gross of sequestration and (b) net of sequestration; and what was the contribution for 2024.

UK net territorial CO2 emissions were 603.3 million tonnes in 1990 and provisionally estimated at 290.4 million tonnes in 2024.

Source: DESNZ, provisional 2024 UK net territorial greenhouse gas emissions statistics.

CO2 is calculated in terms of net emissions, which means total emissions minus total removals from the atmosphere. Therefore, it is not possible to report gross CO2 emissions.
