Deal and scope

Under the agreement GS Caltex will supply the equivalent of 2,000 tons of Neat SAF (100% SAF) to DHL Express aircraft that refuel in Korea over the next year.
Production method and certification
The SAF to be supplied is produced via co‑processing and carries ISCC EU certification in compliance with the European Union’s Renewable Energy Directive.
Logistics and carbon programme
