Sky-High Stakes and the Big Bet on Biofuel

Four industry titans unite to secure 11 million gallons of sustainable fuel, proving that pooled demand is the secret to decarbonizing the skies

12 May 2026

Four companies have reshaped what corporate SAF demand can look like. Announced in April 2026, the agreement between DSV, United Airlines, Phillips 66, and Microsoft unlocks up to 11 million gallons of sustainable aviation fuel, delivering an expected reduction of approximately 100,000 metric tonnes of lifecycle greenhouse gas emissions versus conventional jet fuel. Confirmed as the largest contracted SAF deal with a single customer in United Airlines' Eco-Skies Alliance history, the partnership breaks new ground on both scale and structure.

Phillips 66 supplies the fuel from its California-based Rodeo Renewable Energy Complex, using waste fats, oils, and greases as feedstock. DSV and Microsoft participate through a book-and-claim model, receiving verified emissions credits without physically consuming aviation fuel.

Scale is the breakthrough here.

SAF accounts for only around 2% of US jet fuel consumption under 2026 Energy Information Administration projections, exposing a vast gap between current supply and net-zero targets. Long-term offtake certainty is what producers need to justify expanded capacity investment, and this agreement's multi-sector structure directly delivers it. Coordinating demand across logistics, technology, aviation, and fuel supply, the deal proves that pooled corporate commitment can unlock production volumes no single buyer could secure alone.

Grounding the model is a rigorous accountability layer, with every tonne of CO2 reduction certified under International Sustainability and Carbon Certification standards, tracked through the SAF Certificate Registry, and protected against double-counting. Lauren Riley, Chief Sustainability Officer at United Airlines, described the outcome as proof of what becomes possible when every link in the supply chain commits to shared results.

Replication is now the sector's most urgent challenge, and this partnership has set the template. As carbon intensity rules tighten across US fuel markets and corporate net-zero commitments harden into procurement obligations, cross-sector demand aggregation is shifting from innovative exception to industrial necessity, with cleaner skies now firmly in sight.
