Neste, ITOCHU and GS Caltex have collaborated to make the first batch of CORSIA-eligible ISCC-certified sustainable aviation fuel (SAF) available for purchase at Narita International Airport in Japan. This is the first time that CORSIA-certified SAF was made available for airlines’ regular purchase at commercial scale, well ahead of the start of CORSIA’s mandatory phase in 2027.

As part of the collaboration, Neste supplied over 1,000 tons of neat (i.e. unblended) CORSIA-eligible and ISCC-certified Neste MY Sustainable Aviation Fuel™ to the refinery of GS Caltex in Yeosu, South Korea to be blended with conventional jet fuel. This marked the first time SAF was blended locally in South Korea. The blended SAF was then transported to Japan for ITOCHU to supply it into the fuel storage facilities at Narita International Airport. The first batch of the fuel will be offered to All Nippon Airlines (ANA) and Japan Airlines (JAL).

CORSIA is a recognized scheme offering a harmonized way to reduce CO2 emissions from international aviation to curb its impact on climate change. It was developed by the International Civil Aviation Organization (ICAO), and the implementation of CORSIA is currently in the first, voluntary phase. Once certified by an ICAO-approved sustainability certification scheme, SAF qualifies as a CORSIA Eligible Fuel (CEF) and can be used by an airline to meet the CO2 emission reduction allocation requirements under CORSIA. 

Using unblended Neste MY Sustainable Aviation Fuel™ can reduce greenhouse gas emissions (GHG) by up to 80%* over the fuel’s life cycle, compared to using conventional jet fuel.
