Aviation and Shipping: Exhaust Emissions

Question for Department for Energy Security and Net Zero

UIN HL884, tabled on 5 December 2023

To ask His Majesty's Government, further to United Kingdom of Great Britain and Northern Ireland’s Nationally Determined Contribution updated in September 2022 (CP744), why the Climate Change Committee advised that emissions from international aviation and shipping should not be included; and in particular, whether this was because of the difficulty in attributing emissions to specific countries.

The Climate Change Committee is an independent advisory authority. In 2020, it advised that the UK’s 2030 Nationally Determined Contribution should commit to reduce emissions by at least 68% from 1990 to 2030, excluding emissions from international aviation and shipping (IAS), in line with UN convention.

IAS emissions are included in the UK’s domestic sixth carbon budget. The Government has set out ambitious strategies to reduce emissions from aviation and shipping through the Jet Zero Strategy and Clean Maritime Plan.
