Aviation: Exhaust Emissions
The question
To ask the Secretary of State for Transport, pursuant to the press release entitled £43 million boost for green aviation to drive growth, jobs and cleaner flights, published on 20 January 2026, what proportion of global aviation emissions her Department estimates will be removed as a result of the funding for green aviation projects.
Answered by Keir Mather
Through the Carbon Budget and Growth Delivery Plan, published on 29 October, the Government detailed policies in place to reduce greenhouse gas emissions from fuels in aviation, and estimates of the emission reductions they would achieve. This package of funding will help to enable these emission reductions.
The nature of research and development activity creates challenges in assessing the exact expected CO2 benefits at the outset, as these depend on the extent to which the outputs of research and new technologies are adopted into commercial use, and the pace at which this happens. Government seed funding is integral in supporting early-stage research and development for technologies which are not yet commercially viable but could be scaled in future.
