Heathrow is once again urging the government to invest £4 billion annual intake from Air Passenger Duty to raise production of ‘green’ aviation fuels.
The revenue generated from the air tax could help to accelerate the production of biofuels and support the ambition of a net-zero carbon aviation industry by 2050.
The airport first made the demand for a reform of APD last month.
Heathrow sustainability director Matt Gorman said: “Having won an overwhelming majority in Parliament supporting expansion at Heathrow we are getting on with delivering a project that will connect the whole country to economic growth in a way that is sustainable and responsible.
“We understand the responsibility our sector has to help tackle climate change and ensure we protect a world worth travelling, which is why we’re calling on government to invest the revenue generated from Air Passenger Duty in sustainable fuels.
“This move will help to drive a much needed change in our sector and make travel more sustainable.”
The call came as the London hub revealed that SAS took the top spot in its ‘Fly Quiet and Green’ airline sustainability league table in the second quarter of the year.
The result came as the Scandinavian flag carrier reduced early and late flights.
The airline also scored well for its operational performance by improving its ‘track keeping’ – following preferential noise route flight paths precisely and using a quieter landing method known as continuous descent approach.
The league table compiles the results of the airport’s top 50 busiest airlines from April to June, rating how each airline scores for operational factors such as punctuality, track keeping, continuous decent approach, and monitors the fleet upgrades that help to reduce emissions.
Both 787 Dreamliners and Airbus A350s are among the top environmental performers, helping airlines to rise in the rankings.
Qantas jumped 28 spots to sixth place, earning the title of most improved airline, after achieving 100% compliance for track keeping and running its schedule without late or early flights.
The announcement coincided with Heathrow’s 12-week expansion consultation, which details measures the airport will be putting in place to reduce emissions and provide respite for local communities as part of its plans for a third runway. The consultation runs until September 13.
