The company supplied about 5,000 kiloliters of CORSIA SAF, blended with conventional aviation fuel, to Narita Airport in Japan last Friday through Itochu Corp.
It marked the first commercial-scale sale of CORSIA SAF by a Korean refiner, certified by the International Civil Aviation Organization (ICAO). The fuel will be sold to Japanese airlines such as ANA and JAL.
SAF is produced from agricultural and waste feedstocks. As global carbon regulations and greenhouse gas reduction efforts continue, the use of SAF is becoming increasingly mandatory.
According to GS Caltex, SAF can reduce carbon emissions by up to 80 percent compared to conventional aviation fuel.
The Korean government recently announced plans to mandate a 1 percent SAF blend for all international flights departing from Korea starting in 2027.
"By recognizing the global aviation industry's decarbonization trends and customer needs, and leveraging support from both the Korean and Japanese governments as well as our partners' expertise, we have established a new value chain," said Lee Seung-hoon, head of GS Caltex's supply and trading division. "We plan to expand our cooperation with various partners in the future."
