Airlines are enthusiastically embracing sustainable aviation fuel (SAF) as part of their commitment to reducing carbon dioxide emissions, which currently contribute 2.5-3.5% to global greenhouse gas emissions, as reported by Our World in Data1. While already implementing measures like improved routing and aircraft design to minimize their carbon footprint, airlines are eagerly awaiting the availability of sufficient SAF to power their planes.

SAF holds significant promise for reducing carbon footprint for several reasons. First, its production often requires fewer resources, resulting in a lower carbon footprint. In fact, some SAF solutions can be produced in a way that is carbon-neutral or even carbon-negative. Additionally, SAF typically emits less CO2 and other pollutants, further enhancing its environmental benefits.

The potential of SAF has garnered high-level attention, with US President Joe Biden setting ambitious targets to produce SAF in the United States: 3 billion gallons by 2030 and 35 billion gallons by 2050. This ambitious goal underscores the significance of the SAF industry.

As many airlines have signed advance purchase agreements for future SAF volumes, key players such as Neste and World Energy are undergoing substantial expansions to ramp up SAF production. Neste's global Renewable Aviation business is set to significantly increase its production capacity. By modifying its biofuel refinery in the Netherlands, the company will be able to produce over 1.8 billion liters of SAF in 2024, up from its current capacity of 1.3 billion liters at its plants in Finland and Singapore. Meanwhile, World Energy's plant in Southern California is undergoing an expansion that's halfway finished. This expansion will increase their capacity from 270 million liters per year to more than 950 million liters by late 2026.
