Korean Air has reached a significant milestone in its commitment to reducing carbon emissions by becoming the first Korean flag carrier to operate commercial flights powered by domestically produced Sustainable Aviation Fuel (SAF). The first flight using SAF, KE719 from Seoul Incheon to Tokyo Haneda, marks a new chapter in the airline’s sustainability efforts. This transition aligns with the global aviation industry’s push to reduce its environmental footprint, positioning Korean Air as a leader in the region’s green aviation movement.
At VURDHAAN, we recognize the importance of SAF in achieving global aviation decarbonization targets. As sustainability consultants specializing in CORSIA, SBTi, and ReFuelEU initiatives, we work closely with airlines and aviation stakeholders to develop tailored strategies for reducing emissions through innovative solutions like SAF and fleet modernization.
A New Era of Domestic SAF
The introduction of domestically produced SAF by Korean Air is a notable achievement for Korea’s aviation sector. Beginning on August 30, 2024, through July 2025, Korean Air will utilize a 1% SAF blend on its weekly flight from Seoul Incheon to Tokyo Narita. This initial step serves as the foundation for the airline’s broader plan to expand SAF usage across medium- and long-haul routes.
The SAF used for these flights is supplied by two leading Korean energy companies—S-Oil and SK Energy. Both companies produce SAF from sustainable materials like used cooking oil and animal fats, ensuring the fuel meets International Civil Aviation Organization (ICAO) standards under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA).
The Environmental Impact of SAF
SAF is a critical tool in the aviation industry’s decarbonization efforts. With the ability to reduce carbon emissions by up to 80% compared to traditional jet fuel, SAF is seen as a game-changer for airlines looking to minimize their environmental impact. The beauty of SAF lies in its compatibility with existing aviation infrastructure—no aircraft modifications are needed, and up to 50% SAF can be blended with conventional fuel under current regulations.
By using sustainable feedstocks such as waste oils and animal fats, SAF production significantly reduces lifecycle emissions. These feedstocks help repurpose materials that would otherwise contribute to waste, aligning with global circular economy goals.
Global Momentum for SAF Adoption
The use of SAF is gaining momentum around the world. The European Union‘s ReFuelEU Aviation policy mandates a 2% SAF blend for all flights departing EU airports by 2025, with an ambitious target of reaching 70% by 2050. Meanwhile, the United States has launched the SAF Grand Challenge, which aims to meet 100% of its aviation fuel demand with SAF by 2050.
Korea is also laying the groundwork for significant SAF market growth. In 2022, the government announced the Eco-friendly Biofuel Expansion Plan, and recent amendments to the Petroleum and Alternative Fuel Business Act further demonstrate the country’s commitment to increasing SAF production and use. Korean Air’s leadership in this area sets a precedent for other carriers in the region, showcasing the importance of innovation in green aviation.
VURDHAAN’s Commitment to Aviation Sustainability
At VURDHAAN, we are at the forefront of guiding aviation companies through the evolving landscape of sustainability regulations and decarbonization initiatives. As experts in CORSIA, SBTi, and Sustainable Aviation Fuel integration, we help airlines develop comprehensive strategies that not only reduce emissions but also align with global environmental targets. We believe in the power of sustainable innovations like SAF to drive long-term change in the aviation industry, and we are proud to support organizations like Korean Air in their journey toward a greener future.
Through our Support, Educate, and Implement model, we assist aviation businesses in understanding and capitalizing on the benefits of SAF, from compliance with international regulations to optimizing fleet performance with next-generation aircraft.
Looking to the Future
Korean Air’s adoption of SAF marks a significant step in the global effort to decarbonize aviation. The airline’s leadership in this area sets a strong example for others to follow, and with ongoing advancements in SAF production, the aviation sector is poised for a greener future. By continuously upgrading its fleet with fuel-efficient aircraft and expanding its SAF use, Korean Air is well-positioned to meet its long-term carbon reduction goals.
At VURDHAAN, we are excited to see how the industry evolves, and we remain dedicated to helping aviation companies implement sustainable solutions that drive meaningful impact.
