American Airlines, Google Ink Largest SAF Purchase Deal

A Landmark Agreement for Aviation Decarbonization

American Airlines and Google have announced the largest Sustainable Aviation Fuel (SAF) purchase agreement between a corporate buyer and an airline to date. This multi-year partnership aims to reduce approximately 300,000 metric tons of Carbon Dioxide Equivalent (CO2e) emissions. The agreement centers on the procurement of 35 million gallons (132 million liters) of SAF, which will be physically delivered to Chicago O'Hare International Airport (ORD) over the next three years.

This deal represents a significant step in aviation decarbonization by leveraging corporate travel budgets to scale the supply of lower-carbon fuels. According to the American Airlines Newsroom, the fuel will be produced by Valero and integrated into the airport's existing fuel supply chain. The partnership is a major test case for how large-scale corporate demand can bridge the current supply gap for alternative fuels.

The Role of the SAFc Registry

A central component of this agreement is the use of the SAFc Registry, a platform co-founded by the Sustainable Aviation Buyers Alliance (SABA). Because physical SAF is often not available at every airport where an airline operates, the registry allows for a SAFc Registry book-and-claim model. This mechanism enables corporations to purchase the environmental attributes of SAF produced elsewhere, ensuring that the carbon reduction benefits are accurately tracked and verified for Scope 3 aviation emissions reporting. Google Sustainability has emphasized that this transparency is critical for maintaining the integrity of corporate climate targets.

Economic Drivers and Regulatory Support

The financial viability of this project is heavily supported by the Illinois Sustainable Aviation Fuel Purchase Credit. Administered by the Illinois Department of Revenue, this incentive provides a $1.50 per gallon tax credit for SAF sold to or used by air carriers within the state. This legislative support was a key enabler for the ORD-based delivery, as it helps offset the significant 'green premium' associated with renewable fuels compared to conventional kerosene-based jet fuel.

Scaling SAF Through Aggregated Demand

Historically, the aviation industry has struggled with the high costs and limited availability of alternative fuels. The Google-American partnership follows a trend of aggregated demand signals, where corporations and airlines pool their purchasing power to provide producers with the capital certainty needed to scale operations. This model has been refined through previous precedents, such as the April 2026 consortium between DSV, Microsoft, and United Airlines, which secured 11 million gallons of SAF. While these agreements are growing in scale, the Sustainable Aviation Buyers Alliance continues to provide the framework necessary to ensure these transactions remain robust and verifiable.

Technical Analysis: The Impact of Book-and-Claim

The transition toward book-and-claim models represents a structural shift in how the industry approaches emissions reductions. By decoupling the physical fuel delivery from the environmental attribute, airlines can optimize their logistics while corporations can still effectively mitigate their travel-related carbon footprints. Data indicates that Illinois is a strategic location for this initiative, as it consumes nearly 70,000 barrels of jet fuel per day, ranking it among the highest-demand states in the U.S. By directing the physical SAF to a high-volume hub like ORD, the partners ensure that the fuel is fully utilized, while the book-and-claim system allows Google to claim the carbon reduction benefits. This approach contrasts with earlier, smaller-scale projects, such as the 2021 Deloitte and Delta partnership, which focused on smaller volumes and less integrated accounting frameworks. However, as noted by the International Council on Clean Transportation, there remain long-term concerns regarding the scalability of waste-based feedstocks and the potential for indirect land-use changes.

What Comes Next: Delivery and Policy Milestones

The partnership is expected to reach its primary milestone with the completion of the 35-million-gallon physical delivery by mid-2029. In the interim, both companies will continue to monitor the efficacy of the SAFc Registry in managing these claims. From a regulatory perspective, the Illinois SAF tax credit is currently scheduled to remain in effect until December 31, 2032, providing a stable window for further investment in the state's SAF infrastructure.

Why This Matters for Corporate Travel

For corporate travel managers, this agreement validates the use of SAF certificates as a scalable and transparent tool for meeting net-zero goals. It signals to the broader market that large-scale corporate buyers are willing to commit to multi-year offtake agreements, which in turn reduces the risk for biofuel producers like Valero. Ultimately, this deal demonstrates how state-level incentives, when combined with corporate demand, can accelerate the transition to sustainable aviation.
