The development of alternative aviation fuels could be the key to sustainable air travel, contributing hugely to the industry's emissions-reduction strategy. Using alternative fuels could reduce CO2 emissions by around 80% compared to fossil fuels, without significant changes to fuel supply systems or engines. Research is also underway into fuels that could have a negative emissions lifecycle.
Since the first biofuel test flight on a commercial aircraft took place in 2008, there has been a huge amount of work by the industry and our partners. Certification through the global fuel standards agency ASTM allowed us to operate using biofuels and more than 225,000 flights have taken place on alternative-traditional fuel blend since 2011.
