WASHINGTON - The airline industry's flagship goal of decarbonising by 2050 is now "in peril" due to climate-sceptic policies, including those of US President Donald Trump, the leading airline association IATA warned on Sunday.
The emergence of leaders favouring fossil fuels and recent regulatory rollbacks are "obviously a setback... it does imperil success on the 2050 horizon", Marie Owens Thomsen, the International Air Transport Association's senior vice president for sustainability, told reporters.
"But I don't think it's going to halt or reverse progress. I think it will just slow progress," she said at the IATA annual industry conference in India.
Trump's Republican administration is supporting the development of fossil fuels in contrast to his Democratic predecessor Joe Biden, who had massively supported the production of renewable aviation fuels through tax credits.
UN aviation agency members, from the International Civil Aviation Organization (ICAO), have set the year 2050 as their goal for achieving net-zero carbon emissions for air travel -- an industry often criticised for its outsized role in climate change.
The air transportation industry has faced growing pressure to deal with its contribution to the climate crisis.
Currently responsible for 2.5 percent to three percent of global CO2 emissions, the sector's switch to renewable fuels is proving difficult, even if the aeronautics industry and energy companies have been seeking progress.
To achieve net-zero emissions, airlines rely on non-fossil sources known as Sustainable Aviation Fuel (SAF).
However, SAF biofuels are still three to four times more expensive than petroleum-based jet fuel.
SAF is seen as a crucial ingredient in hitting emissions targets. The biofuel produces lower carbon emissions than traditional jet fuel and is made from plant and animal materials such as cooking oil and fat.
European Union rules require carriers to include two percent of SAF in their fuel mix starting this year, rising to six percent in 2030 before soaring to 70 percent from 2050.
IATA also indicated on Sunday that it expects global SAF production to double this year compared with 2024 to 2.5 billion litres -- slightly down from its previous projections of 2.7 billion litres.
"This represents only 0.7 percent of total aviation needs," IATA Director General Willie Walsh said.
