Aer Lingus has today signed a sustainable aviation fuel supply agreement with US-based renewable fuels producer Gevo - a major step in its commitment to a lower-carbon future.
The deal will see Aer Lingus buy 19,000 tonnes of sustainable aviation fuel (SAF) per year for five years.
Aer Lingus has pledged to achieve net zero carbon emissions by 2050 and has committed to powering 10% of its flights using sustainable aviation fuel by 2030.
Aer Lingus plans to start fuelling its aircraft with SAF from Gevo from 2026, adding that the introduction of SAF as a renewable fuel source is instrumental in realising its ambitions.
Aer Lingus chief executive Lynne Embleton said the deal with Gevo marks an exciting and critical step on the airline's journey to net zero carbon emissions and underlines its commitment to powering 10% of flights using sustainable aviation fuel by 2030.
"The sustainable aviation fuel produced by Gevo will be used to power our flights from Los Angeles and San Francisco and, from 2026, 50% of fuel purchased by Aer Lingus from California will be sustainable aviation fuel," the Aer Lingus CEO said.
"Gevo's sustainable aviation fuel delivers renewable energy to a transportation sector that is actively seeking to reduce its carbon intensity," said Dr Patrick R Gruber, Gevo's chief executive.
"Because our fuel is fungible and drop-in ready, it's expected to have an immediate impact to help our partner airlines achieve their sustainability targets ahead of schedule," he added.
Aer Lingus last month signed a lease agreement for two new Airbus A320neo aircraft which will see this new generation aircraft joining the airline's fleet for the very first time.
The airline said that investing in more fuel-efficient aircraft, along with sustainable aviation fuel, is another key driver of its sustainability programme.
Other initiatives adopted by the airline to drive sustainability include a carbon offsetting tool which enables Aer Lingus customers to offset their flight emissions and support a range of global carbon reduction projects - such as rainforest protection and reforestation programmes.
