Singapore Airlines Group Expands Sustainability Leadership with Major Sustainable Aviation Fuel Agreements

The Singapore Airlines (SIA) Group has taken a major step forward in its decarbonisation journey by entering into strategic agreements with global sustainable fuel producers Neste and World Energy. These newly signed agreements aim to procure Sustainable Aviation Fuel (SAF) and associated SAF certificates (SAFc), significantly strengthening the Group’s environmental credentials while deepening engagement with key stakeholders in the green aviation fuel ecosystem.

Through this dual partnership, the SIA Group seeks not only to reduce its carbon footprint but also to expand its role in shaping the future of aviation sustainability. The move also supports the global aviation sector’s shift towards greener energy alternatives in alignment with international climate commitments and regulatory frameworks.

Singapore-Based SAF Supply Strengthened

Under the agreement with renewable fuel producer Neste, SIA secured the supply of one thousand tonnes of neat SAF. This fuel, which fully complies with the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), was refined at Neste’s advanced facility in Singapore. Following on-site blending, the SAF was delivered directly to Singapore Changi Airport. This marks SIA’s second successful procurement of neat SAF from Neste’s Singapore plant, further cementing the city-state’s emerging status as a hub for renewable aviation fuel production and distribution.

By sourcing SAF locally, SIA is not only reducing transportation-related emissions associated with fuel logistics but also supporting the development of Singapore’s SAF infrastructure and the resilience of its aviation fuel supply chain. This initiative aligns with national goals to position Singapore as a sustainable aviation leader in the Asia-Pacific region.

U.S. Partnership with World Energy Advances Book & Claim Model

In a complementary move, SIA also acquired an additional two thousand tonnes of CORSIA-eligible SAF in the form of environmental attributes—commonly referred to as SAF certificates—from U.S.-based sustainable fuel pioneer World Energy. This acquisition was facilitated through the “Book & Claim” Chain of Custody mechanism, which allows airlines to account for carbon reduction benefits without the need for direct fuel delivery or physical usage.

The Book & Claim approach is particularly valuable for global carriers like SIA, enabling flexible, scalable access to SAF benefits even in markets where physical SAF availability may be limited. The transaction underscores SIA’s commitment to using innovative models that foster global SAF demand and accelerate the sector’s decarbonisation.

Together, these two agreements—finalised during the first quarter of 2025—are expected to offset over nine thousand five hundred tonnes of carbon dioxide emissions. This outcome reinforces SIA’s proactive stance on climate action and positions the airline as a regional leader in sustainable aviation.

Driving Regional Collaboration Through Green Fuel Forward

Beyond procurement, SIA continues to collaborate on broader sustainability efforts. It remains a key participant in the Green Fuel Forward campaign, launched by the World Economic Forum in partnership with Singapore’s GenZero. The campaign aims to mobilize corporate support, boost regional SAF demand, and drive cooperation among airlines, fuel suppliers, and governments across Asia-Pacific.

By aligning itself with high-impact initiatives such as Green Fuel Forward, SIA not only enhances its own sustainability strategy but also contributes to a regional movement focused on long-term carbon neutrality in aviation.

What is SAF and Why It Matters

Sustainable Aviation Fuel (SAF) is a renewable and environmentally responsible alternative to traditional fossil-based jet fuel. Derived from sustainable feedstocks such as used cooking oil, municipal waste, and agricultural residues, SAF can reduce greenhouse gas emissions by up to eighty percent over its full lifecycle. Importantly, it is compatible with existing aircraft engines and airport refueling infrastructure when blended with conventional jet fuel, requiring no costly modifications.

SAF usage is tracked and verified through SAF certificates (SAFc), which represent the emissions reductions achieved through its use. These certificates can be traded, sold, or passed on to corporate buyers, enabling both airlines and business clients to claim sustainability benefits, even in scenarios where direct fuel usage isn’t feasible.

SIA’s engagement in SAF procurement and credit systems is closely aligned with CORSIA, the first international framework targeting aviation emissions. Developed by the International Civil Aviation Organization (ICAO), CORSIA encourages airlines to utilize low-carbon fuels—designated as CORSIA Eligible Fuel—to minimize their offsetting obligations.

Accelerating the Aviation Industry’s Low-Carbon Transition

As global aviation works toward ambitious decarbonisation targets, efforts like those by Singapore Airlines serve as essential case studies in innovation, collaboration, and climate responsibility. Through its SAF procurements, strategic partnerships, and participation in regional sustainability campaigns, SIA continues to play a vital role in shaping a cleaner future for air travel—both within Asia and across international skies.
