Hawaiian Airlines Introduces SAF on Osaka–Honolulu Route

On August 29, Hawaiian Airlines announced it will use Sustainable Aviation Fuel (SAF) on flights between Osaka and Honolulu, under a supply agreement between its parent company Alaska Airlines Group and Cosmo Oil Marketing Co., a subsidiary of Cosmo Energy Holdings.

The airline began fueling with SAF at Kansai International Airport in August, marking its first use of the fuel in Japan. SAF can reduce lifecycle carbon emissions by up to 80% compared to conventional jet fuel.

Supported by a NEDO subsidy in 2021, Cosmo’s project uses domestically sourced used cooking oil (UCO) to produce SAF. Its plant will be Japan’s first large-scale SAF facility, with products certified under ISCC CORSIA and ISCC EU standards.
