For several years, sustainable aviation fuel, better known as SAF, lived in a familiar corner of the aviation conversation. It appeared in sustainability reports, pilot programmes, and conference panels, often framed as a promising future solution rather than an immediate operational concern. For most logistics teams, it was something to monitor rather than actively plan around.
That balance has shifted as we move into 2026. SAF is no longer an abstract ambition sitting on the sidelines of airfreight economics. It is now embedded in regulation on key trade lanes, particularly those connected to Europe and the United Kingdom. As a result, SAF is beginning to influence airfreight pricing, contract structures, routing decisions, and, increasingly, logistics budgets at a strategic level.
What makes this transition particularly challenging for shippers and logistics providers is not only the cost impact, but the pace of change. SAF has moved quickly from a voluntary sustainability lever to a compliance-driven input, applied unevenly across regions. The result is a more complex, less uniform airfreight landscape that rewards preparation and penalises surprise.
Regulation is setting the pace, not market demand
The dominant driver behind SAFâs growing impact on airfreight in 2026 is regulation rather than organic market adoption. In Europe, the introduction of the ReFuelEU Aviation framework has fundamentally altered fuel economics for any flight uplifted at EU airports. The regulation mandates a minimum SAF blending share starting at 2 percent and rising on a defined trajectory in the years ahead.
The United Kingdom has followed with its own SAF mandate, reinforcing cost pressure at major UK hubs. For airlines operating freighters or carrying bellyhold cargo into Europe, SAF uplift is no longer optional or flexible. It is required regardless of prevailing fuel prices or local availability.
These mandates do not operate in isolation. They interact with existing mechanisms such as the EU Emissions Trading System and the global CORSIA framework, which allow airlines to use SAF to reduce offset obligations. The combined effect is a concentrated regulatory cost burden on Europe-linked routes.
Industry bodies such as International Air Transport Association have already estimated that SAF-related premiums added several billion dollars to airline fuel bills in 2025 alone, with Europe accounting for a significant share. For air cargo, this concentration matters. A shipment moving from Asia to Europe now carries a different regulatory cost base than a similar shipment flying within Asia or between the Middle East and Asia, even when aircraft type and distance are comparable. That regulatory asymmetry is increasingly shaping network design, pricing strategies, and carrier selection.
Supply has grown, but not fast enough
While policy ambition has accelerated, SAF supply has struggled to keep pace. Global production roughly doubled between 2024 and 2025, approaching two million tonnes. Even with continued growth in 2026, SAF still represents well under one percent of total global jet fuel consumption.
The reasons are familiar to anyone who follows fuel or energy markets. Sustainable feedstocks, particularly waste oils and residues that meet sustainability criteria, are limited. Advanced production pathways such as power-to-liquid fuels require significant capital investment and long development timelines. Distribution infrastructure is uneven, with SAF readily available at a handful of major hubs and largely absent at many secondary airports.
For air cargo, this uneven availability creates practical challenges. Airlines often cannot physically uplift SAF on every regulated flight, particularly on long-haul routes linking Asia with Europe or North America. As a result, much of the industry has turned to book-and-claim systems, where the environmental benefit of SAF is purchased separately from the physical fuel used on a given flight.
This approach allows airlines and shippers to comply with regulations and meet emissions targets, but it also adds another layer of complexity to cost allocation and carbon accounting.
The SAF price premium is changing airfreight economics
The most immediate commercial impact of SAF comes from its price. Across 2024 and 2025, SAF has typically traded at three to five times the cost of conventional jet fuel, a premium that persists into 2026 due to supply constraints and production costs.
Fuel has historically represented around 20 to 30 percent of airline operating expenses, depending on market conditions. When even a small portion of that fuel basket is priced at several multiples of the norm, the effect on overall costs becomes material. For freighter operators and bellyhold carriers alike, recovering those costs is unavoidable.
What has changed most visibly in 2026 is transparency. Airlines are increasingly unbundling SAF costs rather than embedding them invisibly within generic fuel surcharges. Many shippers now see SAF reflected as a distinct line item or a clearly defined component of fuel surcharge formulas, particularly on Europe-origin or Europe-destination lanes.
This transparency helps explain why rates are rising, but it also complicates benchmarking. Two quotes with similar base rates can diverge meaningfully once SAF pass-through is applied, depending on a carrierâs sourcing strategy, contract structure, and regulatory exposure.
How airlines are implementing SAF on the ground
There is no single airline playbook for SAF implementation. Most carriers have focused first on meeting regulatory requirements, ensuring that mandated uplift occurs where required. Beyond that baseline, strategies vary widely.
Some airlines invested early in long-term SAF offtake agreements, often at fixed or semi-fixed prices. These arrangements provide greater cost predictability and reduce exposure to short-term price spikes. Carriers following this approach tend to be better positioned to smooth volatility across their networks and to offer more stable pricing to customers.
Others rely more heavily on spot procurement or book-and-claim certificates. While this can offer flexibility, it also exposes airlines to sharper price fluctuations, particularly when mandates tighten or supply is disrupted.
A growing number of carriers are also positioning SAF as a differentiated cargo product rather than a pure compliance cost. On selected routes, shippers can opt into SAF-backed services that offer verified emissions reductions through physical uplift or certificates. This approach is especially visible in pharmaceutical, electronics, and express cargo markets, where customers are often willing to pay a premium to support Scope 3 decarbonisation goals.
Shippers are responding in different ways
Shipper responses to SAF-driven cost increases vary significantly by sector, margin structure, and service requirements. Large multinationals with public climate commitments often absorb SAF premiums as part of broader ESG strategies. For these organisations, higher airfreight costs are weighed against reputational risk, investor scrutiny, and regulatory disclosure requirements under frameworks such as the EU Corporate Sustainability Reporting Directive.
In contrast, cost-sensitive shippers with more flexible lead times are reassessing their modal mix. Forwarders increasingly report clients shifting replenishment volumes from air to ocean or rail, while reserving airfreight for product launches, promotions, or supply-chain disruptions. The âair for launch, ocean for sustainâ model has become more common as SAF-related premiums widen the cost gap between modes.
This divergence highlights an important point. SAF does not affect all cargo equally. Time-critical, high-value, or temperature-controlled goods are more likely to remain on airfreight despite rising costs, while lower-margin goods are more exposed to modal substitution.
Book-and-claim as a bridge between ambition and availability
Given physical supply constraints, book-and-claim systems have emerged as a pragmatic bridge solution. Through initiatives such as the Sustainable Aviation Buyers Alliance, shippers can purchase SAF certificates representing verified emissions reductions, even if their cargo does not physically fly on SAF-fuelled aircraft.
These programmes have already channelled hundreds of millions of dollars into SAF production and have enabled companies to make measurable progress on Scope 3 targets. Electronics manufacturers, pharmaceutical firms, and global retailers have been among the most active participants, often working through freight forwarders that aggregate demand across multiple customers.
While book-and-claim continues to attract debate around accounting and transparency, it has become an important mechanism for scaling SAF in the near term, particularly for global supply chains with complex routing patterns.
Competitive dynamics in air cargo are evolving
SAF adoption is quietly reshaping competition within air cargo. Airlines with strong balance sheets, early SAF investments, and access to reliable supply are better positioned to serve ESG-driven customers and to offer predictable pricing. Smaller carriers, or those based in regions without binding SAF mandates, may enjoy shortterm cost advantages on certain corridors, but risk being sidelined in premium cargo segments.
Freight forwarders are also adapting. Large global players increasingly act as SAF aggregators, bundling shipper demand and integrating emissions data into customer platforms. This allows them to offer branded low-carbon airfreight products and to support customers with reporting and compliance. Smaller forwarders, by contrast, may struggle to compete if they cannot access comparable programmes or data transparency.
What this means for logistics planning in 2026
By 2026, SAF has become a practical input into logistics planning rather than a peripheral sustainability topic. Shippers are starting to factor SAF exposure into lane selection, favouring hubs with reliable SAF access or robust book-and-claim systems. Contract structures are evolving to include clearer SAF clauses, shared risk mechanisms, and more transparent surcharge formulas.
At the same time, emissions data quality is becoming a differentiator in tenders. Logistics providers that can clearly explain SAF costs, quantify carbon impacts, and support credible reporting are better positioned to win and retain business.
Perhaps the most significant shift is conceptual. Airfreight is gradually becoming a carbon-priced product rather than a uniform commodity. SAF makes the carbon component visible, variable, and increasingly unavoidable.
