SINGAPORE – Boeing accused the world’s biggest oil companies of doing too little to produce sustainable jet fuel as frustration inside the aviation industry grows about the lack of supply.

Sustainable aviation fuel, made from waste oils and agricultural feedstock, can cut carbon emissions from air travel by as much as 80 per cent, according to the airline sector.

An enormous ramp-up in production is essential to give the industry a chance of reaching its target of carbon neutrality by 2050.

Global supply of SAF, as the sustainable fuel is commonly called, meets barely 1 per cent of the aviation industry’s requirements.

Major oil producers “need to lean in harder” and crank up production, Mr Robert Boyd, Boeing’s head of sustainability for the Asia-Pacific region, said in an interview at the Singapore Airshow on Feb 20.

Smaller and less-established green fuel producers such as Neste and SkyNRG are doing a better job of building out a sustainable aviation fuel industry than well-resourced giants like ExxonMobil, according to Mr Boyd.

“I don’t think they’re doing enough,” he said of the traditional energy sector.

The inadequate flow of SAF has been a major talking point at the air show. Lifting supply is also essential to making SAF more affordable for airlines.

Conventional jet fuel is already one of the biggest costs for carriers, and SAF can be three to five times more expensive.

Aviation’s transition to net-zero will require an investment of as much as US$5 trillion (S$6.7 trillion) till 2050, much of it needed to increase sustainable fuel production, according to the International Air Transport Association (Iata). 

Iata chief Willie Walsh on Feb 19 implored oil producers to make more low-emissions aviation fuel.

Every drop that is made will be bought, even at the current high price, Mr Walsh said.

Speaking at an aviation summit in Singapore, he described the airline industry’s struggle to decarbonise as an “existential issue”.

At the same event, Exxon’s vice-president for Asia-Pacific fuels, Ms Ong Shwu Hoon, said the company is focused on making more low-emissions fuel for the transport industry, including aviation.

The SAF supply chain requires more investment, she added.

Exxon, Ms Ong said, is learning to deal with the agricultural companies involved in the new process.

Still, Mr Haldane Dodd, executive director of the Air Transport Action Group, a Switzerland-based non-profit working with the aviation industry to map out a path to net-zero, maintains the energy industry is not doing enough.

Major oil producers are capable of doing much more to support SAF production, Mr Dodd said in an interview at the Singapore Airshow.

“If anybody has the capital, the expertise, the intelligence and the human resources to deliver this product, it’s them,” he added. BLOOMBERG
