Heathrow expansion needs airline-funded CO2 removal: CCC — SkimNews

- The Climate Change Committee told the government that building a third runway and new terminals at Heathrow would breach UK carbon budgets and make net zero by 2050 impossible under current policies.
- CCC chair Nigel Topping said the only way expansion could fit within climate commitments was for airlines to become more efficient, scale up sustainable aviation fuel use, and pay to permanently remove and store CO2, applying the "polluter-pays principle."
- Costs passed to passengers would add an estimated £150 to a return flight to Alicante by 2050 and roughly £400 to a New York flight, phased in gradually over 25 years, according to the CCC's report.
- Friends of the Earth and the Tyndall Centre dismissed the plan, arguing SAF and carbon removal technologies are unproven and unlikely to scale fast enough, and called on ministers to halt all airport expansion outright.
- Aviation emissions data in the CCC report shows the sector now produces more carbon than UK electricity generation, accounts for 9% of national emissions, and has seen passenger demand nearly triple from 100 million in 1990 to 300 million in 2025.
- Frequent flyers — just 5% of the population who took five or more return flights abroad in 2024 — accounted for a third of all flights, and the highest income group took 38% of all flights abroad, four times the rate of the lowest income group.
- Airlines UK rejected the CCC's approach as unaffordable, warning it would "put holidays out of reach for millions," while the Department for Transport said any expansion must align with net zero targets and could deliver £40bn to the economy and 60,000 local jobs.
Why it matters: Heathrow expansion would lock the UK into decades of higher aviation emissions — now 9% of national totals and rising — and the CCC is explicitly warning ministers that without binding legislation forcing airlines to fund carbon removal, approving a third runway makes the 2050 net zero target mathematically impossible. The cost of compliance (up to £400 per long-haul flight) would be borne by passengers, with frequent flyers (5% of the population) responsible for a third of all flights, sharpening the equity stakes of any eventual policy.
