The first barge shipment of sustainable aviation fuel ever delivered to Massachusetts arrived at Boston Logan International Airport this week, the Massachusetts Port Authority said on Oct. 29, 2026. Delta Air Lines and Shell Aviation coordinated the delivery of more than 1 million gallons of blended sustainable aviation fuel, or SAF, which went into Logan’s shared fuel supply that serves every airline at the airport.

Key figures: 1M+ gallons of blended SAF delivered · up to 80% lower lifecycle emissions · $1.50 to $2.00 per-gallon state credit · $10 million yearly credit cap · Massport net-zero goal moved to 2028

What Arrived at Logan and Who Paid for It

The delivery came by barge, which Massport described as a first for the state. Sustainable aviation fuel is made from renewable or waste-based feedstocks rather than crude oil, and it is blended with regular jet fuel before it goes into an airplane. Depending on how it is produced, SAF can cut lifecycle carbon emissions by up to 80% compared with conventional jet fuel, according to Massport.

Because the fuel was added to Logan’s common supply, it is not set aside for Delta’s planes alone. Flights by other carriers that draw from the shared system will burn some of the blend. Massport did not say what share of the 1 million-plus gallons was pure SAF and what share was conventional jet fuel, so the actual volume of renewable fuel in the shipment is smaller than the headline number.

Hoodline, citing Delta, reported that the delivery is part of a five-year supply agreement between Delta and Shell that runs through 2030. Delta has also been expanding its Boston network, including the new Boston to Reykjavik nonstop planned for 2027.

The State Tax Credit Behind the Shipment

The delivery follows a state tax credit for sustainable aviation fuel that Gov. Maura Healey signed in June. The credit is worth $1.50 to $2.00 per gallon, depending on how much the fuel cuts emissions, and total credits are capped at $10 million a year, according to Massport. CommonWealth Beacon reported that the law provides the $10 million for each of the next three years, and that Massport CEO Rich Davey led the push for it. Boston 25 News reported that Massachusetts became the eighth state with a SAF incentive of this kind.

Supporters argue the credit is needed because SAF costs far more than regular jet fuel. CommonWealth Beacon, citing the report of the state’s SAF working group, said the fuel costs about twice as much as conventional jet fuel. Massport created that working group, the Massachusetts SAF Working Group, which sent its recommendations to the governor in 2025.

Massport has also moved up the target for cutting emissions from its own operations. The authority now aims to reach net zero by 2028 instead of 2031, it said. That goal covers Massport’s own operations, not the airlines’ jets.

By the Numbers: How Far the $10 Million Cap Goes

The cap sets a hard ceiling on how much fuel the state can help pay for each year. Dividing the $10 million annual cap by the per-gallon credit rates gives a simple measure of the program’s reach. At the top rate of $2.00 a gallon, the cap covers 5 million gallons a year. At the base rate of $1.50, it covers about 6.67 million gallons.

Those figures are an upper bound on gallons, not a forecast. The credit applies to the SAF content, and it cannot exceed the state jet fuel excise tax a company pays, according to a summary of the law. Because the first delivery was a blend, the pure SAF in it is below the 1 million-gallon mark shown in the chart. Even so, the comparison shows that the yearly cap could support several shipments of this size, but only a few million gallons in total.

For scale, CommonWealth Beacon noted that SAF is still less than 1% of jet fuel used worldwide, while the Federal Aviation Administration’s goal is for SAF to meet 100% of U.S. aviation fuel demand by 2050. Davey told the outlet that about $42 million in aviation fuel-related taxes was collected at Logan last year, which puts the $10 million cap in context as roughly a quarter of that amount.

What It Means for Logan and Boston Business

For Boston, the shipment is an early test of whether a capped state incentive can bring a costlier specialty fuel into Logan’s supply in meaningful volumes. It also adds to a list of changes at the airport, from terminal and roadway improvements to new international routes. More Boston company and deal coverage is on our Boston business news hub.

What to watch next is how much the credit is actually claimed in its first year, whether other airlines sign SAF supply deals at Logan, and whether lawmakers expand or let the credit lapse when its current funding period ends.

Reactions

State officials, including Healey, state Sen. Nick Collins and state Rep. Adrian Madaro, along with Davey and Charlotte Lollar, Delta’s director of SAF and emissions, are quoted in Massport’s announcement welcoming the delivery. Not everyone was convinced when the credit passed. CommonWealth Beacon quoted critics including Chuck Collins of the Institute for Policy Studies, and Mark Sandeen, who said, “$30 million is a rounding error on a rounding error.”
