"Heathrow's annual sustainability report summarizing the year 2025 describes climate change as "an existential threat to aviation, to the planet and to us all personally." The report touts a few areas of interest, including adding zero-emission buses to the airport's fleet and reducing overall waste at Heathrow by 3%. The report also points to Heathrow using more sustainable jet fuel, with 3.1% of the flights taking off from the airport making use of such materials."
"Heathrow revealed that planes' emissions were down by 7% since 2019, with more efficient aircraft cited as a contributing factor. Between 2019 and 2025, Heathrow's "on the ground carbon emissions" dropped by 18%, but the supply chain carbon emissions had risen by 16%. "[I]ncreased capital expenditure" was the reason cited."
Heathrow Airport, Europe's busiest airport, faces a dilemma between capitalizing on renewed post-pandemic air travel demand and addressing environmental concerns about carbon emissions. The airport's 2025 sustainability report acknowledges climate change as an existential threat while outlining concrete actions: adding zero-emission buses, reducing waste by 3%, and increasing sustainable jet fuel usage to 3.1% of flights. Plane emissions decreased 7% since 2019 through more efficient aircraft. However, results are mixed: on-ground carbon emissions dropped 18% between 2019 and 2025, while supply chain emissions rose 16% due to increased capital expenditure. These sustainability efforts may facilitate approval for a third runway expansion.
