The Singapore Airlines (SIA) Group has signed agreements with Neste and World Energy to acquire Sustainable Aviation Fuel (SAF)[1] and SAF certificates[2] respectively, supporting its decarbonization journey while gaining further valuable insights into the pathways, standards, and certification systems in the renewable fuel landscape.
The first transaction saw the group acquire 1,000 tonnes of Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA)-eligible[3] neat SAF, sourced from renewable fuel producer Neste. The SAF was produced at Neste’s Singapore refinery, blended locally and uplifted at Singapore Changi Airport. This is the Group’s second purchase of neat SAF from the Singapore refinery, helping to develop the country’s SAF ecosystem and enhance supply chain resilience.
In addition, the group purchased approximately 2,000 tonnes of CORSIA-eligible SAF in the form of emissions reductions from World Energy, a United States-based producer, utilizing the Book & Claim Chain of Custody model[4]. This allows the Group to claim associated emissions reductions without physical fuel delivery.
Both deals were completed in the first quarter of 2025 and these transactions are projected to reduce more than 9,500 tonnes of carbon dioxide emissions.
SIA also participates in the Green Fuel Forward campaign, an initiative designed to boost the demand for SAF in the Asia-Pacific region. Launched by the World Economic Forum and Singapore’s GenZero, the campaign seeks to enhance awareness and understanding of SAF, while actively promoting its use and fostering strategic partnerships between regional corporations and airlines.
Lee Wen Fen, Chief Sustainability Officer, Singapore Airlines, said: “These agreements represent important steps in the SIA Group’s broader strategy to scale up its use of sustainable aviation fuel. By working with different suppliers and exploring diverse sourcing models and certification pathways, we gain crucial insights into the SAF landscape and we can better understand the pathways towards a more sustainable aviation ecosystem.
“The SIA Group will continue to work with partners around the world to test and implement solutions that support the airline industry’s long-term decarbonisation goals. This will allow us to validate SAF demand, enhance our technical expertise in this area, and strengthen our ability to meet our medium-term commitment of 5% SAF use by 2030 and long-term goal net zero carbon emissions by 2050.”
[1] SAF is a low-carbon alternative to conventional jet fuel, produced from renewable or waste-derived sources. It can reduce greenhouse gas emissions by up to 80% over the fuel’s life cycle. Blended with conventional jet fuel, it seamlessly integrates with existing aircraft engines and fuelling infrastructure.
[2] SAFc represent the emissions reductions achieved from using SAF. Fuel suppliers record these certificates in a SAF registry and transfer them to airlines, who can then pass them on or sell them to corporate buyers. This enables airlines to claim environmental benefits without directly using the fuel, while supporting the growth of the SAF market.
[3] Developed by the International Civil Aviation Organization (ICAO), CORSIA is the first global market-based measure to address the climate impact of international aviation. It recognises certified SAF as CORSIA Eligible Fuel, which airlines can use to lower their carbon offsetting obligations under the scheme.
[4] The Book & Claim Chain of Custody model separates a product’s environmental benefits from its physical delivery. With this, airlines can purchase and claim the emissions reduction benefits without physically using the SAF. This allows for more flexible and widespread adoption of SAF, supporting the industry’s sustainability efforts regardless of geographical constraints.
