DSV has announced a landmark collaboration with Microsoft, United Airlines, and Phillips 66 to unlock 11 million gallons (41.6 million litres) of sustainable aviation fuel (SAF). The deal represents the largest contracted supply agreement in the history of United’s “Eco-Skies Alliance” and is expected to reduce lifecycle greenhouse gas emissions by approximately 100,000 tonnes compared to conventional jet fuel.
The partnership creates a coordinated supply chain where Phillips 66 provides the fuel, United Airlines operates the flights, and DSV and Microsoft participate via a “book-and-claim” methodology. This system allows verified emissions reductions to be allocated to specific shippers independently of the physical fuel use, ensuring the environmental impact is tracked transparently.
“By connecting customers, carriers, and fuel producers, we can help turn sustainability ambitions into operational outcomes,” said Frank Sobotka, CEO of DSV’s Air & Sea Division.
The transaction is supported by International Sustainability and Carbon Certification (ISCC) and tracked through the SAFc Registry. This rigorous verification process ensures that the fuel is produced from sustainable feedstocks and that emissions reductions are protected against double-counting.
Lauren Riley, Chief Sustainability Officer at United Airlines, noted that the scale of the agreement demonstrates what is possible when the entire value chain—from supplier to end customer—works in unison. Microsoft also highlighted the role of the deal in decarbonising its cloud logistics operations.
“Phillips 66 has the integrated assets and logistics network to deliver SAF at scale today,” added Ronald Sanchez, Vice President of Aviation at Phillips 66. “We’re helping turn demand for lower-carbon aviation into reliable, real-world supply.”
