Conclusion
Third Report - Net zero and the UK avia…
Accepted
The impact of conventional aviation activity on climate is still not fully quantifiable. While the contribution of aviation to levels of atmospheric CO and other greenhouse 2 gases is quantifiable and substantial, the climate impact of other emissions from aviation is currently not well understood and difficult to quantify. Measures …
Government response. The government agrees with the conclusion, affirming its commitment to accelerate work on aviation's non-CO2 climate impacts by launching a multi-year, multi-million research program and establishing a Task and Finish Group that agreed to short-term actions for 2024. Findings from …

Conclusion
Third Report - Net zero and the UK avia…
Accepted
Sustainable aviation fuels may offer a means of reducing the carbon emissions attributable to the lifecycle of aviation kerosene from its production to its combustion, and the Government envisions a substantial role for SAFs. There is nevertheless potential for wide variability in lifecycle emissions across the general class of fuels …
Government response. The government commits to monitoring progress against emissions targets annually from 2025, conducting major reviews of the Jet Zero Strategy every five years (first in 2027), and producing a comprehensive monitoring and evaluation framework.
15
Recommendation
Third Report - Net zero and the UK avia…
Accepted
We are concerned that the broad definition of what is currently considered a sustainable fuel, and the absence of a global standard for SAFs, may lead to the development of aviation fuels which cannot credibly be described as sustainable. We recommend that the Government take every opportunity to establish in …
Government response. The government agrees with the recommendation, confirming it will introduce a SAF mandate from 2025 with strict sustainability criteria to ensure genuine lifecycle emissions savings. It will also require evidence of lifecycle emissions from fuel producers and is supporting the …

22
Recommendation
Third Report - Net zero and the UK avia…
Accepted
Zero-emission flight is sometimes described as providing ‘guilt-free’ flying. While it is the case that ZEF technologies remove the CO2 emissions from conventional aircraft movements which are aviation’s most damaging effect on the environment, the potential effects on the atmosphere from both hydrogen and battery-electric flight are not fully known. …
Government response. The government accepted the recommendation, confirming it launched a multi-year, multi-million aviation non-CO2 research programme in October 2023, with further calls planned, and specifically focusing on hydrogen-powered aircraft impacts.
23
Conclusion
Third Report - Net zero and the UK avia…
Accepted
Requiring airlines to set a price on their emissions, and purchase credits for these emissions through a trading scheme, can be a constructive mechanism to ensure that the carbon cost of aviation is more adequately reflected in the cost to the consumer. This in itself may influence consumer demand for …
Government response. The government agrees with the mechanism described and commits to enhancing the UK ETS for aviation, including phasing out free allocation by 2026 and developing proposals for how the UK ETS should treat Sustainable Aviation Fuels (SAF).
24
Conclusion
Third Report - Net zero and the UK avia…
Accepted
We welcome the decision of the UK Government and devolved administrations to end the issuing of free ETS allocations to aviation with effect from the 2026–2030 allocation period. We note that the use of SAF in aviation is currently zero-rated for ETS, even though the emissions from burning SAF in …
Government response. The government agrees, confirming the phase-out of free ETS allocations by 2026 and stating they will develop and consult on proposals for how the UK ETS should treat SAF in the future, exploring alternative options for its pricing.
25
Recommendation
Third Report - Net zero and the UK avia…
Accepted
We recommend that the Government implement its proposed changes to the UK ETS so as to remove conventional aviation fuel from free allocations, and that it consult on a methodology to include SAF in the ETS in a way which does not inhibit the development and use of SAF in …
Government response. The government agrees with the recommendation, confirming the phase-out of free aviation fuel allocations by 2026 and committing to developing and consulting on proposals for how to treat Sustainable Aviation Fuel (SAF) within the UK ETS.
26
Conclusion
Third Report - Net zero and the UK avia…
Accepted
Offsetting mechanisms, such as CORSIA, may provide an interim step towards contributing to the removal from the atmosphere of the emissions attributable to UK aviation. We commend the Government on the work it has already undertaken at international level to secure an agreement on an international offsetting mechanism. More remains …
Government response. The government agrees with the committee's observation, detailing its leading role in the ICAO CAAF/3 agreement for a 5% global aviation fuel emissions reduction target by 2030, which enshrined the CORSIA sustainability approach for SAF as a comprehensive international standard.
27
Conclusion
Third Report - Net zero and the UK avia…
