The UK aviation sector is calling for urgent government support to meet its net zero carbon target by 2050. Sustainable Aviation, a coalition of airlines, airports, and plane makers, published its 2026 Decarbonisation Roadmap warning that without policy action, costs for passengers could rise and the UK could lose global competitiveness. Under the roadmap, Sustainable Aviation Fuel (SAF) would make up 65% of aviation fuel by 2050, down from an earlier estimate of 75%. The group says greenhouse gas removals will need to account for 29% of reductions, removing roughly 19.5 million tonnes of CO2 annually. Emissions per passenger have already fallen 22% since 2005, while passenger numbers rose 28%. The coalition wants the government to fund aerospace innovation, speed up airspace upgrades, make SAF affordable, and create a cost-effective carbon removals system. Without these measures, the industry warns transition costs will be higher than in competitor markets.

SAF dropping from 75% to 65% of the fuel mix by 2050 is a pretty big revision. Either the tech is scaling slower than they hoped or the cost curves are worse than expected. Would like to see the assumptions behind that change.

19.5 million tonnes of CO2 removal per year is a huge number. That is more than double their previous estimate. What kind of removals are they banking on? Direct air capture at that scale is not proven yet.

Emissions per passenger down 22% is decent but absolute emissions only down 1% over 20 years while passenger numbers grew 28%. That means the efficiency gains are being eaten by growth. Net zero by 2050 will require actual absolute cuts not just per passenger improvements.

The ask for government support is vague. Fund innovation, speed up upgrades, make SAF affordable. That is not a policy proposal. What specific mechanism? A mandate? A subsidy? A carbon price floor for aviation? Without details this is just a wishlist.

Worth noting the coalition includes airlines and plane makers. They have a clear interest in framing this as needing government money rather than internal investment. The roadmap is a lobbying document as much as a technical plan.
