Heathrow Airport Reports 7% Reduction in Flight Carbon Emissions for 2025, Driven by Sustainable Aviation Fuel
✈️ In 2025, Heathrow's carbon emissions from flights dropped 7% compared to 2019, driven by increased use of sustainable aviation fuel (SAF), which constituted 3.1% of the fuel used last year. SAF can cut emissions by up to 80%. Heathrow, managing a record 478,000 passenger flights last year, aims for a 15% emissions reduction by 2030. This progress supports plans for a third runway.
