The fuel is regular fossil jet bundled with well-to-wing carbon offsets rather than sustainable aviation fuel (SAF). SK Energy says it will eventually offer carbon-neutralized versions of all petroleum products after securing nature-based carbon offsets from Macquarie Group. Meanwhile Korean Air has already signed a memorandum of understanding with Japan's Hyundai Oilbank to develop SAF production. The airline says it is looking at various methods to reduce carbon emissions to achieve carbon-neutral growth and fight climate change. The airline is an active participant in the International Civil Aviation Organization’s Carbon Offsetting and Reduction Scheme for International Aviation. It recently introduced new fuel-efficient A220-300 aircraft that offer 25% fewer carbon emissions per seat.
