Lauren Riley, chief sustainability officer for United Airlines, the third largest airline in the US, said in an interview with the Financial Times that sustainable aviation fuel will be economically viable only if there is cooperation with the oil industry.
She highlighted that one of the big problems for sustainable jet fuel providers was a lack of infrastructure.
Riley said, “They don’t have access to the pipelines. They don’t have the traditional logistics support. We’re going to need access to pipelines. Oil companies are a critical part of the solution.”
Most sustainable aviation fuel (SAF) is produced from recycled cooking oil but can also be derived from other sources like household waste. SAF costs at least twice as much per gallon as conventional jet fuel.
SAF manufacturers also struggle to secure the necessary investment and support to scale production to meet the aviation industry’s demands.
However, she expressed confidence that new technology will enable sustainable jet fuel to be produced from a broader range of sources. She expressed her optimism about the potential of e-fuels.

Riley highlighted that global SAF production last year was 150 million gallons (570 million litres), while the United alone consumed 4.2 billion gallons (16 billion litres) of conventional jet fuel.
United Airlines aims to achieve Net-Zero carbon emissions by 2050. However, only 0.1 percent of the fuel it uses annually is sustainable. Riley noted that only a few producers of SAF exist, including Finland’s Neste and California-based World Energy.
