Airlines Must Pay for CO2 Removal to Expand Heathrow: CCC — SkimNews

- The Climate Change Committee told the government Heathrow's third runway expansion should only proceed if airlines pay for permanent CO2 removal, increase sustainable aviation fuel use, and become more efficient—or it will breach UK carbon budgets and make net zero by 2050 impossible.
- CCC Chair Nigel Topping warned that if Heathrow gets expansion consent without legislation forcing the industry to clean up its emissions, "there will be a big red light flashing" in the CCC's report to parliament.
- The CCC estimated costs of SAF and carbon removal would likely add ~£150 to a return flight to Alicante and ~£400 to New York by 2050, phased in gradually over 25 years.
- Friends of the Earth campaigner Tony Bosworth accused the CCC of "pulling its punches," citing Tyndall Centre research that found SAF and carbon removals are unproven and unlikely to scale fast enough to justify expansion.
- The CCC found aviation now accounts for 9% of UK emissions—more than electricity generation—with passenger demand nearly tripling from 100 million in 1990 to 300 million in 2025.
- The CCC flagged that frequent flyers (5+ return flights abroad in 2024) are just 5% of the population but took a third of all flights, while the highest income group took 38% of flights—four times the lowest group—yet stopped short of recommending a frequent flyer levy.
- Heathrow said expansion "must deliver both" economic growth and net zero; Airlines UK CEO Tim Alderslade said the CCC plan would "put holidays out of reach for millions"; the Department for Transport said any expansion must align with net zero, citing £219m in SAF investment and £43m in cleaner technologies.
Why it matters: The CCC's warning creates a hard climate-law checkpoint: if ministers approve Heathrow expansion without legislation mandating industry cleanup, the project directly undermines the UK's carbon budgets. Passengers face estimated fare hikes of £150–£400 per return flight by 2050, with the burden falling heaviest on the 75% of people in England who don't fly abroad at all.
