IATA estimates that 2026 global SAF production of 2.4 Mt — representing just 0.8% of aviation fuel consumption — is already costing airlines $4.3 billion annually, while binding mandates in the EU (6% by 2030) and the UK (10% by 2030) will multiply that compliance cost before supply has scaled to meet it. EASA's 2024 European reference benchmarks show a gross SAF price premium of €1,351/t above conventional jet fuel, with eSAF — subject to an EU sub-mandate beginning in 2030 — priced at €7,695/t, more than 10× conventional fuel. S&P Global's March 2026 data further shows the premium is not a fixed number: it fell from $1,463.25/t to $1,139/t within two weeks as jet-fuel prices rose faster than SAF prices, meaning the effective airline cost is governed by the interaction of fuel markets, supply structures, and policy mechanisms — not by SAF production economics alone.
This report is the first executive-intelligence resource to decompose the SAF premium into its ten constituent cost layers, map those layers across six regulatory environments with verified benchmark data, model three distinct premium-compression scenarios through 2030, and translate that analysis into a procurement decision framework. It draws exclusively on verified institutional data from IATA, EASA, S&P Global, ICAO, the European Commission, and regional government authorities. No figure is estimated or inferred where it is not confirmed by an authoritative source.
The SAF Premium: Five Executive Signals Every Airline Leader Must Act On
DIRECT ANSWER The SAF price premium in 2026 is not a single global number. EASA's 2024 European reference data shows a gross premium of €1,351/t — with SAF at €2,085/t against conventional jet fuel at €734/t, a multiple of 2.84×. S&P Global assessed the live European HEFA SAF market premium at $1,139/t on 11 March 2026, and the Asia-Pacific premium at $1,497.50/t on 7 July 2026. The effective airline cost differs materially from these benchmarks based on pathway, policy support, and contract structure.
EXECUTIVE SIGNAL 1
The SAF premium is not one number — it is a cost stack, and airlines are managing the wrong variable when they track only the headline price.
FINDING: EASA's 2024 European reference premium is €1,351/t, but the effective airline cost includes feedstock, production, certification, blending, logistics, supplier compliance charges, and mandate-certificate costs — all of which differ by geography, pathway, and contract structure.
SO WHAT: An airline benchmarking only the €2,085/t EASA reference price — or the $1,139/t S&P market premium — is tracking a component of its cost exposure, not the total.
NOW WHAT: Airline procurement and finance teams must build a full cost-stack model before any SAF contracting or budgeting decision is made for 2027 or beyond.
EXECUTIVE SIGNAL 2
Who captures the SAF premium is actively disputed — and the evidence does not yet settle the question.
FINDING: IATA Director General Willie Walsh stated in June 2025 that suppliers were charging compliance fees that value SAF at double its market premium over conventional fuel — a claim that, if verified, would mean airlines are paying a multiple of the already-elevated HEFA benchmark.
SO WHAT: This is an airline-industry advocacy position, not independently verified market data — but it signals that the cost stack above the production benchmark is a live commercial dispute with material financial implications for airline fuel budgets.
NOW WHAT: Airlines should audit their SAF cost invoices against market benchmark prices for the relevant delivery geography and pathway before renewing or extending any existing supply agreements.
EXECUTIVE SIGNAL 3
eSAF creates a second and structurally larger cost problem that binding sub-mandates will force airlines into before the economics are ready.
FINDING: EASA's 2024 reference price for eSAF (power-to-liquid synthetic aviation fuel) is €7,695/t — 3.69× the HEFA SAF reference price of €2,085/t and more than 10× conventional jet fuel at €734/t.
SO WHAT: The EU's synthetic-fuel sub-mandate under ReFuelEU Aviation creates regulatory demand for eSAF before the technology reaches HEFA cost levels — exposing airlines in EU markets to a materially higher effective premium from the late 2020s.
NOW WHAT: Airlines with significant European route exposure must model the eSAF sub-mandate cost impact separately from the HEFA SAF premium in their 2028–2030 fuel cost projections.
EXECUTIVE SIGNAL 4
The 2030 SAF premium will not converge through scale alone — specific conditions must be met, and not all of them are on track.
FINDING: The US has more than $44 billion in announced SAF capacity funding targeting over 3 billion gallons/year by 2030 — but announced capacity is not operating capacity, and authoritative feedstock and policy data indicate that HEFA alone cannot scale to close the premium without feedstock diversification, cheaper renewable energy for eSAF, and persistent policy support.
SO WHAT: Airlines and investors relying on a single 2030 SAF price forecast are making procurement or capital decisions on an assumption the evidence does not support.
NOW WHAT: Use the three conditional scenarios in Section 9 of this report — Slow Scale, Accelerated Scale, and Cost Convergence — to stress-test your procurement strategy rather than planning against a single price point.
EXECUTIVE SIGNAL 5
Procurement timing carries more risk in both directions than most airline strategy teams currently model.
FINDING: Airlines with EU route exposure face a binding 6% SAF mandate by 2030 and a UK mandate of 10% by 2030 — while global SAF production in 2026 covers only 0.8% of total aviation fuel consumption, meaning supply will tighten against mandate demand before new capacity comes online.
SO WHAT: Locking in long-term SAF offtake agreements today provides supply certainty but carries contractual risk if SAF costs fall faster than expected; waiting provides optionality but risks supply scarcity and compliance penalties under binding mandates.
NOW WHAT: Airlines must map their specific route-network mandate exposure against their risk tolerance before choosing between spot procurement, indexed offtake, fixed offtake, or upstream co-investment — the GFJ SAF Procurement Decision Matrix in Section 8 provides the analytical framework.
Executive Signal Summary — GFJ SAF Price Premium Report 2026
Signal | Key Verified Data Point | Strategic Implication | Action Implied |
1. It is a cost stack | EASA gross EU premium: €1,351/t | Headline price understates effective airline cost | Build a full ten-layer cost model |
2. Who captures it is disputed | Walsh: suppliers charge at 2× market premium (IATA, Jun 2025) | Supplier margins above production benchmark are a live commercial dispute | Audit SAF invoices against market benchmarks |
3. eSAF is a second problem | eSAF at €7,695/t vs HEFA at €2,085/t | Sub-mandates force expensive pathways before economics are ready | Model eSAF exposure separately from HEFA in fuel budgets |
4. 2030 convergence is conditional | $44bn US announced capacity vs fraction operational | Scale alone will not close the premium | Use three-scenario framework, not a single forecast |
5. Procurement timing is two-directional risk | EU 6% mandate 2030; UK 10% mandate 2030; SAF = 0.8% of supply now | Both early and late contracting carry material risk | Map route exposure to mandate obligations before contracting |
Why SAF Economics Became a Board-Level Question in 2026
DIRECT ANSWER SAF represented only 0.8% of global jet-fuel consumption in 2026 despite generating an estimated $4.3 billion in additional airline costs. Production has grown — from 1.0 Mt in 2024 to 1.9 Mt in 2025 and 2.4 Mt in 2026 — but against total aviation fuel consumption exceeding 300 Mt, the supply gap remains vast. Binding mandates of 6% in the EU by 2030 and 10% in the UK by 2030 are now creating mandatory SAF demand before supply has scaled. The premium is no longer a voluntary expenditure; it is an emerging compliance and procurement cost.
2.1 — The Supply Gap: 2.4 Mt of Production vs 300+ Mt of Demand
FINDING: Global SAF production grew from 1.0 Mt in 2024 to 2.4 Mt in 2026 — a meaningful increase, but one that leaves SAF at just 0.8% of aviation's total fuel consumption of more than 300 Mt/year.
SO WHAT: At 0.8% penetration, producers hold significant pricing power and airlines have limited ability to negotiate at scale — creating the structural conditions for a persistent premium rather than a competitive market.
NOW WHAT: Airlines should not assume that production growth alone will compress prices before 2030; pricing leverage will remain with producers until supply reaches a materially higher share of jet-fuel consumption.
The scale of the supply gap is the most important single fact in SAF economics. SAF production more than doubled between 2024 and 2026 alone — from 1.0 Mt to 2.4 Mt — and it still covers less than 1% of aviation fuel demand. IATA's Director General Willie Walsh expressed the industry's position directly:
“SAF volumes are increasing, but disappointingly slowly.”
— Willie Walsh, Director General, International Air Transport Association (IATA), 10 December 2024, IATA press release
That slow growth rate reflects feedstock constraints, financing barriers, and the long lead times required to take a new SAF facility from project announcement to commercial operation. The gap between announced capacity and operating capacity — discussed in Section 7 — is one of the most consequential variables in the 2030 premium outlook.

Global SAF Production Timeline — Volume and Share of Jet Fuel Consumption
Year | SAF Production (Mt) | Share of Aviation Fuel (%) | Key Policy Event |
2024 | 1.0 | ~0.3% | UK SAF mandate enacted |
2025 | 1.9 | ~0.6% | ReFuelEU Aviation 2% obligation begins |
2026 | 2.4 | 0.8% | Singapore SAF levy deferred to Jan 2027 flights |
2030 (target) | TBC | EU: 6% / UK: 10% | ReFuelEU & UK mandates binding thresholds |
2.2 — The Regulatory Architecture: Three Economic Models
FINDING: Three fundamentally different regulatory models are now operating simultaneously — the mandate model (EU and UK), the producer-incentive model (US), and the cost-socialisation levy model (Singapore) — each with a distinct effect on where in the supply chain the SAF premium is absorbed and by whom.
SO WHAT: A global airline with operations across all three regulatory environments carries three structurally different types of SAF cost exposure simultaneously — making a single global SAF cost assumption in fuel budgeting analytically inadequate.
NOW WHAT: Finance and strategy teams must model SAF cost exposure separately by regulatory regime and route network, not as a single blended airline-wide figure.
Apostolos Tzitzikostas, European Commissioner for Sustainable Transport and Tourism, described the EU's commitment to SAF investment in November 2025:
“Our Sustainable Transport Investment Plan is a decisive step towards a sustainable future.”
— Apostolos Tzitzikostas, Commissioner for Sustainable Transport and Tourism, European Commission, 5 November 2025, European Commission press release
The EU model creates a demand signal and leaves the airline to absorb the residual premium after policy support. The US model reduces production economics before the fuel reaches the airline, allowing the market to determine uptake. Singapore's model explicitly converts the premium into a fixed-cost-envelope levy on tickets and services, creating price predictability for airlines without eliminating the underlying cost.

Three SAF Regulatory Models — Mechanism, Airline Cost Type, and 2030 Position
Model | Markets | Key Instrument | Who Bears the Premium | 2030 Mandate Target |
Mandate | EU, UK | ReFuelEU Reg. (EU) 2023/2405; UK SAF Mandate (from 1 January 2025) | Fuel suppliers (obligation); airlines (compliance cost) | EU: 6% / UK: 10% |
Producer Incentive | US | IRC §45Z Clean Fuel Production Credit | Production economics reduced; airline pays market price | No federal blending mandate |
Cost-Socialisation Levy | Singapore | SAF Levy (CAAS framework) | Aviation users via fixed levy; airlines have price certainty | 3–5% by 2030 |
2.3 — The Conventional Jet Fuel Variable: Why the Premium Is Dynamic, Not Static
FINDING: S&P Global's market data shows the European HEFA SAF premium fell from $1,463.25/t to $1,139/t between two assessment dates in early 2026 — not because SAF became cheaper, but because conventional jet-fuel prices rose faster than SAF prices.
SO WHAT: The SAF premium is a relative measure — it is the subtraction of conventional jet-fuel price from SAF price — meaning a rising oil market can narrow the premium without any change in SAF production economics, and a falling oil market can widen it without any SAF-specific deterioration.
NOW WHAT: Any 2030 SAF cost model that does not include multiple conventional jet-fuel price scenarios — covering at least a low ($60–70/bbl) and a high ($90–100/bbl) crude oil environment — is analytically incomplete for procurement or capital-planning purposes.
A SAF cost projection that treats the premium as a fixed figure is analytically wrong — the premium moves continuously with both the SAF market and the conventional fuel market. An airline that signs a long-term SAF offtake at a fixed premium over conventional jet fuel is taking a very different bet from one that signs at a fixed absolute price — and the choice between those structures requires an explicit view on crude oil trajectory. The procurement decision framework in Section 8 addresses this directly.

Decomposing the Premium: What Airlines Are Actually Paying Layer by Layer
DIRECT ANSWER The SAF price premium is not a single item but a stack of costs above conventional jet fuel. It includes feedstock procurement, production conversion, sustainability certification and book-and-claim logistics, blending at the airport, supplier compliance charges and mandate-certificate costs, and any premium embedded in long-term contractual structures. Policy support — tax credits, subsidies, viability gap funding — reduces the effective stack from above. Carbon credit values can offset it further. In Europe in 2024, the EASA reference gross premium was €1,351/t; the effective airline cost can differ materially depending on all these variables.
3.1 — The Ten Cost Layers: From Feedstock to Effective Airline Cost
FINDING: The GFJ Airline Effective SAF Cost Stack comprises ten distinct cost layers — from feedstock procurement through to effective airline net cost — only the first two of which (feedstock and production conversion) are typically reflected in a headline SAF benchmark price.
SO WHAT: An airline reading the EASA reference price of €2,085/t as its SAF cost is looking at an upstream production benchmark, not the delivered, certified, mandate-compliant cost it will actually pay at an EU airport.
NOW WHAT: Every SAF procurement negotiation should explicitly decompose the quoted price into its ten constituent layers before comparison with alternative supply options or structures.
GFJ Airline Effective SAF Cost Stack — Ten Component Layers
# | Cost Layer | Direction | Data Status | Notes |
1 | Feedstock procurement cost | + | Verified (varies by pathway) | UCO, agricultural waste, CO₂ + renewable H₂ for eSAF |
2 | Production/conversion cost | + | Verified (EASA benchmarks) | HEFA: within €2,085/t reference; eSAF: €7,695/t |
3 | Sustainability certification (ISCC, RSB) | + | Present; magnitude not publicly verified in isolation | Required for mandate compliance and CORSIA eligibility |
4 | Book-and-claim logistics | + | Present; varies by delivery model | Physical blending vs mass-balance vs book-and-claim |
5 | Blending and airport delivery | + | Present; country/airport specific | Infrastructure constraints affect logistics cost |
6 | Supplier compliance charge / mandate markup | + | Contested (see 3.2) | IATA claims this doubles the market premium in some cases |
7 | Mandate certificate cost (where applicable) | + | Verified (UK system); varies by market | UK buy-out mechanism sets a cost ceiling |
8 | Government policy support / tax credit | − | Verified by market | US §45Z, EU support, UK grants, Singapore levy offset |
9 | Carbon credit value offset | − | Partial (CORSIA credits: ~$20.97/tCO₂e, H1 2025) | Small offset vs SAF cost; not a substitute for SAF |
10 | Contractual structure premium or discount | +/− | Contract-specific; not publicly available | Long-term fixed, indexed, or hybrid; risk-transfer terms |
The ICAO CORSIA technical assessment estimated SAF at approximately $2/litre against approximately $0.70/litre for conventional jet fuel, with SAF abatement costs of around $600–800/tCO₂. By contrast, CORSIA-eligible carbon credits were averaging approximately $20.97/tCO₂e in H1 2025. This comparison makes clear that SAF is currently a highly expensive marginal decarbonisation instrument on a pure cost-per-tonne-of-CO₂-avoided basis — but it must not be interpreted as evidence that airlines should substitute credits for SAF. Mandate compliance, permanence, additionality, and regulatory eligibility differ substantially between SAF and carbon offset instruments.
The relationship between SAF, carbon markets, and industrial decarbonisation is examined in GFJ's Green Molecules Economy 2035: greenfueljournal.com/post/green-molecules-economy-2035
3.2 — The IATA Supplier-Charge Dispute: Advocacy or Evidence?
FINDING: IATA Director General Willie Walsh stated on 2 June 2025 that fuel suppliers were charging airlines compliance fees that value SAF at double its market premium over conventional jet fuel — a claim that implies a surcharge of up to $2,278/t (twice the $1,139/t S&P European market premium of March 2026) rather than the market premium itself.
SO WHAT: This is the airline industry's position, not independently verified market evidence — but the magnitude of the alleged overcharge, if even partially accurate, would represent a material misallocation of the SAF premium away from producers and toward fuel supply intermediaries.
NOW WHAT: Airlines should obtain itemised cost breakdowns from SAF fuel suppliers, distinguishing production cost, certification cost, compliance cost, and supplier margin before accepting bundled invoice pricing at face value.
“It's an outrage that suppliers are charging airlines compliance fees that value SAF at double its market premium over conventional jet fuel.”
— Willie Walsh, Director General, International Air Transport Association (IATA), 2 June 2025, IATA industry speech.
Note: this represents IATA's airline-sector position. GFJ presents it as an industry claim, not independently verified market data.
The Walsh statement matters regardless of whether the claimed multiplier is precisely accurate. It confirms that the gap between SAF production benchmark prices and the effective cost charged to airlines is a live commercial dispute at the highest level of aviation industry representation. Suppliers have not publicly acknowledged the claim or provided equivalent transparent cost breakdowns. This information asymmetry is itself an airline risk: airlines cannot price or hedge effectively against a cost they cannot accurately decompose. Both the IATA claim and the absence of a publicly verified counter-dataset should prompt airlines to demand greater transparency in SAF supply contracts.
3.3 — Why Pathway Determines Premium: HEFA vs ATJ vs eSAF
FINDING: The HEFA pathway currently dominates global SAF production because it uses mature refinery technology and established feedstocks — but it faces a structural ceiling from constrained waste-oil supply, while the eSAF/PtL pathway is dramatically more expensive at €7,695/t versus €2,085/t for HEFA (EASA 2024), and the ATJ (alcohol-to-jet) pathway remains at early commercial scale.
SO WHAT: The SAF price premium an airline faces in 2030 will depend significantly on which pathways are available in its supply geography — and whether binding sub-mandates force uptake of more expensive pathways before their economics have matured.
NOW WHAT: Airlines planning SAF procurement for 2028–2030 must identify which pathways their intended suppliers can deliver, and whether those pathways will satisfy compliance requirements in each relevant jurisdiction.
SAF Production Pathway Comparison — Economics and Constraints (2024–2026)
Pathway | Feedstock | Technology Maturity | EASA 2024 Reference Cost | Key Constraint |
HEFA | Used cooking oil (UCO), animal fats, plant oils | Commercial scale | €2,085/t | Feedstock supply ceiling; UCO tightening under mandate demand |
ATJ (Alcohol-to-Jet) | Agricultural waste, sugarcane, corn ethanol | Early commercial | Higher than HEFA; not separately benchmarked by EASA 2024 | Conversion efficiency; alcohol feedstock cost |
Gasification / FT | Municipal solid waste, forestry waste | Demonstration/pilot | Higher than HEFA | Capital intensity; long development timelines |
eSAF / PtL | CO₂ + renewable hydrogen (electrolysis) | Pre-commercial | €7,695/t | Renewable electricity cost; green hydrogen cost; scale |
The feedstock question for HEFA and the cost trajectory for eSAF are the two variables that will matter most to the 2030 premium outcome. Section 7 addresses both in detail.

SAF Cost by Geography: Europe, the US, Asia-Pacific, India and the Emerging Markets
DIRECT ANSWER The SAF price premium differs significantly by region. EASA's 2024 European reference data shows a gross premium of €1,351/t — with SAF at 2.84× the conventional fuel price. S&P Global assessed the live European HEFA market premium at $1,139/t on 11 March 2026, and the Asia-Pacific premium at $1,497.50/t on 7 July 2026. The US does not have a federal SAF blending mandate; its SAF economics are shaped by the Section 45Z production credit. Effective airline costs in each market depend on regulatory mechanism, policy support, and contract structure.
Global SAF Premium Comparison — Six Markets (2024–2026)
Market | Conventional Fuel | SAF Benchmark | Gross Premium | Policy Mechanism | 2030 Target | Data Confidence |
EU | €734/t (EASA 2024) | €2,085/t HEFA (EASA 2024) | €1,351/t | ReFuelEU mandate | 6% | High |
UK | Aligned with NW Europe jet | Aligned with EU HEFA market | Approx. equivalent to EU | SAF mandate + certificate/buy-out | 10% | High |
US | Domestic jet fuel market | Market price; §45Z credit reduces producer cost | Not published centrally | §45Z production incentive (no federal mandate) | No federal mandate | Medium |
China | Domestic aviation fuel | S&P premium: $1,472.50/t (Jul 2026) | $1,472.50/t (S&P, 7 Jul 2026) | CAAC pilot programme | No verified nationwide mandate | Medium |
India | ATF market price | No verified SAF benchmark yet | Not publicly available | ATF Control Order (Apr 2026); indicative targets | 5% indicative | Low |
Singapore | Regional jet fuel | Asia-Pacific: $1,497.50/t (S&P, Jul 2026) | $1,497.50/t (S&P, 7 Jul 2026) | Fixed-cost-envelope SAF levy | 3–5% | High (mechanism); medium (effective cost) |
4.1 — European Union: ReFuelEU, EASA Benchmarks, and the Mandate-Driven Cost Floor
FINDING: The EU's ReFuelEU Aviation regulation — Regulation (EU) 2023/2405 — mandates 2% SAF in 2025, rising to 6% in 2030, 20% in 2035, and 70% in 2050, with a separate synthetic-fuel sub-mandate beginning in 2030 — creating the world's most explicit regulatory demand curve for SAF.
SO WHAT: For airlines operating into EU airports, ReFuelEU creates a mandatory fuel cost — a compliance obligation that must be met regardless of whether SAF market prices fall or rise between now and 2030.
NOW WHAT: EU-exposed airlines must plan SAF procurement against the full mandate schedule — 6% by 2030, 20% by 2035 — rather than optimising only for the immediate 2025–2026 obligation.
The European Commission's July 2026 policy analysis explicitly examined how the scale of SAF support affects the effective price paid by airlines — confirming that the gross €1,351/t premium is not the final airline cost, and that support mechanisms reduce the effective burden. However, as the synthetic-fuel sub-mandate approaches in the late 2020s, the eSAF cost differential of €7,695/t creates a significant upward pressure on EU airline fuel costs that policy support alone is unlikely to fully offset at current investment levels.
4.2 — United Kingdom: The SAF Mandate Certificate System and the Buy-Out Ceiling
FINDING: The UK SAF Mandate came into force on 1 January 2025, establishing an obligation of 2% in 2025, rising to 10% in 2030 and 22% in 2040, with a power-to-liquid obligation commencing in 2028 and a certificate system with defined buy-out prices creating an effective cost ceiling for non-compliance.
SO WHAT: The buy-out mechanism sets a maximum cost of compliance for airlines that cannot source sufficient SAF — but that ceiling price is very high, designed to incentivise SAF procurement rather than substitute for it.
NOW WHAT: Airlines with significant UK route exposure should assess their 2030 mandate liability under the 10% threshold and determine whether their contracted SAF supply can meet that obligation before buy-out becomes the default mechanism.
In June 2026, the UK Government announced £219 million of additional support for SAF development, simultaneously reaffirming that the 2030 and 2040 mandate targets would not be reduced. The combination of a high buy-out price, a substantial support package, and an unambiguous mandate trajectory makes the UK one of the highest-certainty SAF demand environments globally. For airlines with substantial UK hub exposure, securing forward SAF supply agreements is a compliance planning requirement, not an option.
4.3 — United States: Production Incentives, Section 45Z, and the Absence of a Federal Mandate
FINDING: The US approach to SAF economics is fundamentally incentive-led rather than mandate-led — the key instrument being the Section 45Z Clean Fuel Production Credit, which was modified materially for fuel produced after 31 December 2025, with the special SAF rate removed, certain foreign feedstocks excluded, and the credit extended to 2029.
SO WHAT: Airlines and investors cannot assess US-produced SAF economics using the old headline $1.75/gallon SAF credit as though it were the current 2026 rule — the incentive structure has changed materially and the effective credit per tonne depends on emissions intensity of the specific fuel produced.
NOW WHAT: Any analysis of US SAF supply costs for 2026–2029 must be based on the revised Section 45Z regulations published by the IRS in February 2026, not on pre-2025 incentive structures.
US domestic SAF production reached approximately 30 million gallons in the first three quarters of 2024, up from 5 million gallons in 2021. Announced domestic capacity represents more than 3 billion gallons/year by 2030, with more than $44 billion in announced project funding. The absence of a federal SAF blending mandate means that US production economics depend on the Section 45Z credit persisting rather than on a regulated demand floor — creating a different risk profile from EU or UK supply.
4.4 — China: Pilot Programme Economics and What the Data Does (and Does Not) Show
FINDING: S&P Global assessed the China SAF premium at $1,472.50/t on 7 July 2026 — comparable to the Asia-Pacific premium of $1,497.50/t on the same date — confirming that the SAF premium is not solely a European phenomenon, even in a market that does not yet have a verified nationwide blending mandate.
SO WHAT: Airlines operating into Chinese airports face a material SAF cost premium even under China's current pilot-programme-only framework — meaning SAF cost exposure in Asia is a present-tense operating issue, not a future regulatory risk.
NOW WHAT: Airlines should not defer Asia-Pacific SAF cost planning until a formal Chinese mandate is announced; current market premiums in the region already represent a material fuel cost variable.
China's SAF programme is advancing through structured pilot activities involving Air China, China Eastern, and China Southern across four airports — a pilot that ran from September through December 2024 with a second phase through 2025. China's 2022 Civil Aviation Green Development Action Plan targeted 50,000 tonnes of cumulative SAF consumption by 2025. In August 2025, a national SAF industry alliance was established involving 57 founding entities.
GFJ notes explicitly: no authoritative public source confirms a nationwide SAF blending mandate in China comparable to ReFuelEU Aviation or the UK SAF Mandate as of 20 August 2026. Any assumption of a Chinese federal mandate in airline cost modelling is not currently supported by verified evidence.
4.5 — India: Emerging Targets, the ATF Control Order Amendment, and the Panipat Plant
FINDING: India amended its ATF (Regulation of Marketing) Order, 2001 in April 2026 to bring SAF-blended aviation turbine fuel within the regulatory framework, while maintaining indicative blending targets of 1% in 2027, 2% in 2028, and 5% in 2030 for international flights.
SO WHAT: The ATF Order amendment is a regulatory enabling step — it removes a structural barrier to SAF commercial deployment in India — but it does not yet create a binding mandate with compliance penalties equivalent to the EU or UK frameworks.
NOW WHAT: Indian airlines should treat the 2027–2030 blending targets as a planning signal rather than a current compliance obligation, while beginning to assess supply options through IndianOil's proposed Panipat plant and international supply agreements.
India's SAF market is covered in full in Section 5. For context on India's broader carbon market and industrial decarbonisation framework, see GFJ's analysis of the Indian Carbon Market 2026: greenfueljournal.com/post/indian-carbon-market-2026-the-new-industrial-operating-system
4.6 — Singapore and Southeast Asia: The Levy Model as Cost Socialisation
FINDING: Singapore's SAF levy framework — now deferred to apply to tickets and services sold from 1 October 2026 for flights departing from 1 January 2027 — operates on a fixed-cost-envelope basis, making the levy amount predictable for airlines regardless of how SAF market prices move.
SO WHAT: Singapore's model is analytically significant because it is the only major regulatory mechanism that explicitly decouples the airline's compliance cost from SAF market price volatility — providing greater cost certainty than either the EU mandate or the US incentive model.
NOW WHAT: Airlines operating hub operations through Changi should assess the levy's impact on their effective fuel cost from January 2027 and compare it against the variable-market-price exposure they carry in EU markets under ReFuelEU Aviation.
Thailand's Alternative Energy Development Plan 2024–2037 includes a 1% SAF blend target in 2026, rising to 8% by 2036 — creating a medium-term Southeast Asian mandate dynamic that will affect fuel suppliers and airlines operating across the region. Thailand's initial production is expected to rely heavily on UCO before transitioning toward ATJ pathways.

India's SAF Market: Policy Targets, Production Realities, and What Indian Airlines Will Pay
DIRECT ANSWER India has set indicative SAF blending targets of 1% in 2027, 2% in 2028, and 5% in 2030 for international flights, and amended its ATF Control Order in April 2026 to bring SAF-blended aviation turbine fuel within the regulatory framework. IndianOil's Panipat refinery is India's first proposed commercial-scale SAF production facility, at 86.8 kt/year of proposed capacity. Indian carriers operating into Europe face indirect SAF cost exposure through ReFuelEU Aviation compliance requirements on those routes. No verified public benchmark for the effective airline SAF cost in India is currently available.
5.1 — Policy Framework: ATF Order, Blending Targets, and the Regulatory Gap
FINDING: India's April 2026 amendment to the ATF Control Order formally brought SAF-blended aviation turbine fuel within the regulatory framework — a structural prerequisite for commercial SAF deployment — while the government's indicative blending schedule of 1%/2%/5% for 2027–2030 provides a planning signal without the compliance penalties of a binding mandate.
SO WHAT: India's regulatory architecture is enabling rather than mandating — the cost incentive for airlines to purchase SAF domestically depends on price competitiveness relative to conventional ATF, not on a penalty-based compliance obligation.
NOW WHAT: Indian carriers should track the government's transition from indicative to binding targets as the timing of that transition will determine when SAF becomes a compliance cost rather than a voluntary procurement decision.
India SAF Policy Timeline — Milestones and Airline Cost Implications
Year | Policy Milestone | Airline Cost Implication |
April 2026 | ATF Control Order amended; SAF-blended ATF brought under regulatory framework | Removes regulatory barrier to commercial SAF supply contracts in India |
2027 | Indicative 1% SAF blending target (international flights) | Potential voluntary procurement pressure; no penalty-based obligation confirmed |
2028 | Indicative 2% SAF blending target | Regulatory expectation rising; Panipat plant timeline becomes a critical variable |
2030 | Indicative 5% SAF blending target | Significant cost exposure if supply insufficient domestically; EU import pricing risk |
5.2 — Production Reality: IndianOil's Panipat Plant and the Domestic Supply Question
FINDING: IndianOil's Panipat refinery represents India's only verified proposed commercial-scale SAF production facility — at 86.8 kt/year of proposed capacity — and IndianOil has signed an MoU with Air India for SAF supply to support CORSIA compliance requirements, creating India's first integrated producer-airline supply arrangement.
SO WHAT: 86.8 kt/year of domestic SAF capacity is meaningful as India's first commercial-scale project — but it remains a very small fraction of India's total aviation fuel consumption, meaning domestic supply will not satisfy the indicative 5% blending target in 2030 without significant additional capacity.
NOW WHAT: Indian airlines planning for the 2030 blending target must assess whether the Panipat plant's output can cover their CORSIA obligations alone, or whether import supply agreements — at European or Asian market premium prices — will be required to bridge the gap.
The IndianOil–Air India MoU represents India's first integrated supply-offtake arrangement for commercial-scale SAF — the foundational structure of a domestic SAF market. The Panipat plant remains a proposed facility at the time of this report's research cut-off of 20 August 2026. GFJ cannot verify a commissioning date or an operating cost benchmark for the Panipat plant from current authoritative public sources.
5.3 — International Route Exposure: What Indian Airlines Pay Under ReFuelEU
FINDING: Indian carriers operating flights into EU airports — including services by Air India on India-Europe routes — are subject to ReFuelEU Aviation compliance requirements on those flights, creating a present-tense SAF cost exposure at European market premium prices, not Indian domestic fuel prices.
SO WHAT: An Indian airline that benchmarks its SAF cost planning against domestic ATF prices is not accounting for the EU-rate premium — approximately €1,351/t gross in the 2024 EASA reference framework — that applies on its EU-destination routes.
NOW WHAT: Indian carriers with significant EU route exposure should model their ReFuelEU compliance cost separately from any anticipated Indian domestic SAF cost, applying the EU regulatory framework and EASA reference benchmarks to the relevant route volumes.
The ReFuelEU obligation falls on fuel suppliers at EU airports — but the economics flow through to airline ticket pricing and fuel cost structure. This international route exposure will grow proportionally as Indian carriers expand their European services.

5.4 — The India Opportunity: Feedstock Position and SAF Production Potential
FINDING: India's large agricultural sector and government-identified biofuel ecosystem provides a potential feedstock advantage for domestic SAF production, particularly for HEFA pathways using non-food oils and for ATJ pathways using agricultural residues.
SO WHAT: India's feedstock position could, over the medium term, support domestic SAF production costs below the European import price — creating both a potential cost advantage for Indian carriers and an export opportunity for SAF producers serving Asian markets.
NOW WHAT: Energy investors assessing the Indian SAF market should evaluate feedstock availability, existing biofuel policy infrastructure, and refinery conversion economics as the primary variables in production cost modelling, rather than applying a simple reference to European HEFA benchmarks.
India vs EU SAF Cost Environment — Key Variables Compared
Variable | India (2026) | EU (2024–2026) |
Regulatory instrument | ATF Control Order amendment; indicative blending targets | ReFuelEU Aviation — Regulation (EU) 2023/2405 — binding mandate |
2030 SAF target | 5% (indicative) | 6% (binding) |
Gross market premium benchmark | Not publicly available (no verified domestic SAF market price) | €1,351/t (EASA 2024 reference) |
Domestic production capacity (verified) | 86.8 kt/year proposed (IndianOil Panipat) | Multiple large-scale HEFA facilities operational |
Feedstock availability | Government-identified agricultural residue and biofuel potential; UCO; potential for ATJ scale | UCO supply constrained; advanced feedstocks expanding |
Compliance penalty regime | Not established at time of writing | Buy-out ceiling mechanism under ReFuelEU |
Four SAF Strategies in Practice: What Leading Organisations Are Actually Doing
DIRECT ANSWER Neste is the world's largest SAF producer, with approximately 1.5 Mt/year of SAF production capability across Singapore and Rotterdam. Airbus and Cathay Group co-invested up to $70 million to accelerate SAF production in October 2025. Air Canada and Airbus committed approximately CAD 13.7 million ($10 million) to support a Canadian SAF ecosystem in July 2026. India's IndianOil is developing the country's first proposed commercial-scale SAF plant at Panipat (86.8 kt/year), under an MoU with Air India for SAF offtake.
The four cases below are specifically selected because each illustrates a distinct commercial model for managing SAF cost and supply risk. Taken together, they reveal a market in which the simple spot-purchase model has been displaced by structured co-investment, long-term offtake, and vertically integrated supply arrangements.
The strategic question for any airline reading these cases is not
"what are these companies doing?" but "which of these structures fits my mandate exposure, capital position, and risk appetite?"
Case Study 1: Neste — The Scale Economics of Integrated Production
FINDING: Neste has reached approximately 1.5 Mt/year of global SAF production capability following expansion at its Singapore refinery and modification of its Rotterdam facility — making it the world's largest SAF producer and the primary benchmark for what integrated HEFA production economics look like at commercial scale.
SO WHAT: Neste's Singapore expansion provides up to 1 Mt/year of SAF optionality from a single facility — demonstrating that SAF can be produced at scale from an existing refinery platform, and that Southeast Asia is strategically central to the global SAF supply chain, not a peripheral market.
NOW WHAT: Airlines seeking long-term HEFA SAF supply in the Asia-Pacific region should assess Neste's Singapore facility as a potential anchor supplier, recognising that its production economics will be influenced by UCO feedstock cost dynamics in the region.
Neste's commercial model is that of a dedicated SAF producer — investing its own capital in refinery conversion and feedstock procurement, then selling SAF at market prices that reflect those costs plus a margin. The airline in this model is a buyer, not a risk-sharer. Neste's scale advantage gives it lower per-unit production costs than smaller producers, but that advantage is constrained by the same UCO feedstock ceiling that affects all HEFA producers globally. The question of whether Neste's capacity growth can keep pace with mandate-driven demand growth across the EU and UK is directly relevant to the 2030 premium outlook modelled in Section 9.
Case Study 2: Airbus and Cathay Group — The Co-Investment Model for Risk Sharing
FINDING: In October 2025, Airbus and Cathay Group announced a joint investment of up to $70 million to accelerate SAF production in Asia and globally — a co-investment structure in which an aircraft manufacturer and an airline share the capital risk of SAF development rather than leaving it solely with fuel producers.
SO WHAT: The Airbus-Cathay model challenges the conventional assumption that SAF development risk sits entirely with fuel producers — it demonstrates that airlines and aircraft manufacturers with aligned long-term interests in SAF cost reduction have both the incentive and the capital to participate in production-side investment.
NOW WHAT: Airlines with large aircraft order backlogs and significant SAF mandate exposure should assess whether upstream co-investment with their primary aircraft manufacturer — modelled on the
Airbus-Cathay structure — offers a lower long-run supply cost than relying entirely on open-market procurement.
When Cathay Group co-invests in SAF production, it is not simply buying fuel — it is securing supply certainty, influencing production economics in its favour, and potentially achieving a cost of SAF below what would be available through open-market spot or even long-term offtake purchases. The $70 million commitment is relatively modest against Cathay's total fuel cost base — but it signals a structural shift in how airline procurement strategy relates to SAF capital allocation.
For context on how co-investment structures are reshaping the broader clean energy market, see GFJ's New Energy M&A Playbook 2026–2027: greenfueljournal.com/post/new-energy-m-a-playbook-2026-2027
Case Study 3: Air Canada and Airbus — The Co-Investment Logic in a Non-Mandate Market
FINDING: In July 2026, Air Canada and Airbus announced a joint initiative with a shared objective to invest approximately CAD 13.7 million ($10 million) to support a commercial-scale Canadian SAF ecosystem — in a market that has no federal SAF blending mandate equivalent to the EU or UK.
SO WHAT: The Air Canada-Airbus commitment demonstrates that co-investment in SAF production is being pursued in non-mandate markets — driven by long-run risk management and CORSIA compliance rather than regulatory compulsion — which has implications for how airlines in all markets should think about their SAF strategy options.
NOW WHAT: Airlines in markets without binding SAF mandates should not treat their absence of regulatory obligation as a reason to defer SAF supply strategy; the Air Canada case demonstrates that long-run supply security and CORSIA positioning are independently sufficient reasons to engage in SAF production investment.
Canada's approach — combining the Clean Fuel Regulations, updated Aviation Climate Action Plan, and Clean Fuels Fund (extended to 2030) — provides a policy environment that de-risks production investment without creating a mandate-driven demand floor. The contrast between the Canadian and EU frameworks illustrates why the same airline group operating across both markets faces structurally different SAF cost exposures in each — and why procurement strategy cannot be standardised across geographies.
Case Study 4: IndianOil and Air India — Building a Vertically Integrated Domestic Supply Chain
FINDING: IndianOil has identified its Panipat refinery as India's first proposed commercial-scale SAF production facility at 86.8 kt/year, and has signed an MoU with Air India for SAF supply to support CORSIA requirements — creating India's first integrated producer-airline supply arrangement.
SO WHAT: The IndianOil–Air India structure is India's attempt to build domestic SAF supply-and-demand infrastructure simultaneously — avoiding the import premium exposure that Indian carriers would face if sourcing SAF from European or Singaporean producers at international market rates.
NOW WHAT: Other Indian carriers operating international routes should assess whether access to the Panipat facility can be arranged under a similar offtake structure, or whether alternative CORSIA-compliant import pathways are required to meet their own CORSIA obligations.
The IndianOil–Air India model is the closest Indian analogue to the vertically integrated approaches being pursued internationally. The key strategic difference is that it is led by a state-owned energy company rather than a private producer — which gives it both the institutional scale to develop a facility of this size and the policy alignment to support India's indicative blending targets. Whether the Panipat facility's SAF production cost will be competitive with the EASA European reference price of €2,085/t is a question GFJ cannot answer from current public data — that calculation would require verified feedstock procurement costs and refinery conversion economics that are not publicly available at time of writing.
What Could Keep the SAF Premium High: Feedstocks, Finance, Volatility, and Policy Risk
DIRECT ANSWER Five structural barriers could prevent meaningful SAF premium compression by 2030: HEFA feedstock constraints as global UCO supply tightens under rising mandate demand; the dramatically higher cost of eSAF/PtL at €7,695/t versus €2,085/t for HEFA (EASA 2024); the gap between $44 billion in announced US SAF capacity and actual operational production; conventional jet-fuel price volatility that changes the effective premium without any change in SAF production economics; and policy fragmentation as markets advance at different speeds toward mandates, incentives, and levy structures.
7.1 — The HEFA Feedstock Ceiling: Why Waste Oils Cannot Scale to Meet 2030 Mandates
FINDING: HEFA dominates current commercial SAF production because it uses mature technology — but global supply of waste fats and oils, including UCO, is being stretched by rising demand as mandates multiply, with S&P Global's December 2025 analysis identifying tightening global UCO supply as a material constraint on HEFA cost competitiveness.
SO WHAT: The feedstock ceiling means the most mature and cost-competitive SAF pathway cannot scale linearly to meet mandate growth — creating upward pressure on HEFA SAF prices even as production capacity expands, because the cheapest feedstock is becoming structurally more expensive.
NOW WHAT: Airlines locking in long-term HEFA SAF offtake agreements should ensure their contracts address feedstock cost pass-through risk — or negotiate fixed-price structures that protect against UCO price escalation in the supply chain.
IATA explicitly identifies HEFA as the most commercially mature and currently cost-effective SAF pathway while simultaneously acknowledging feedstock limitations as a structural constraint on supply growth.
The SAF feedstock transition — from first-generation waste oils toward advanced feedstocks and synthetic pathways — is covered in depth in GFJ's SAF Feedstock Reality Check 2026: greenfueljournal.com/post/saf-feedstock-reality-check-2026
7.2 — The eSAF Problem: Regulatory Demand Before Economic Readiness
FINDING: The EU's synthetic-fuel sub-mandate under ReFuelEU Aviation creates binding demand for eSAF from 2030 onwards — at a time when the EASA 2024 reference price of €7,695/t for eSAF is 3.69× the HEFA reference price and more than 10× conventional jet fuel at €734/t.
SO WHAT: The eSAF sub-mandate is the most significant structural upward pressure on EU airline fuel costs in the 2028–2035 window — it will force airlines to purchase fuel at dramatically higher than current HEFA prices unless eSAF production costs fall substantially before the mandate becomes material.
NOW WHAT: Airlines with EU mandate exposure should model the eSAF sub-mandate cost impact as a separate, additive line item in their 2028–2030 fuel cost projections — not as a blend within the general SAF mandate figure — because the cost differential is far too large to absorb within a single undifferentiated SAF cost line.
The primary input cost for eSAF production is renewable electricity — used to produce green hydrogen via electrolysis, which is then combined with CO₂ to produce PtL synthetic fuel. The future cost trajectory of eSAF is fundamentally linked to the cost of renewable power and green hydrogen electrolysis at industrial scale.
GFJ's analysis of green hydrogen cost economics provides the detailed pathway-to-parity modelling: greenfueljournal.com/post/green-hydrogen-cost-economics-2026-the-real-path-to-price-parity.
The relationship between eSAF and green molecule economics is also examined in GFJ's Green Molecules Economy 2035: greenfueljournal.com/post/green-molecules-economy-2035
7.3 — Announced Capacity Is Not Operating Capacity: The US Reality Check
FINDING: The US has more than $44 billion in announced SAF project funding targeting more than 3 billion gallons/year of potential capacity by 2030 — but domestic production in the first three quarters of 2024 was approximately 30 million gallons, a fraction of announced capacity.
SO WHAT: The gap between announced and operating capacity is one of the most consequential data-quality risks in SAF market analysis — airlines and investors who use announced capacity as a proxy for 2030 supply are overstating the likely availability of competitively priced SAF in that timeframe.
NOW WHAT: All US SAF capacity projections used in procurement or investment analysis should classify projects into three tiers — Announced, FID/Financed, and Operational — and should apply supply assumptions only to projects that have passed a final investment decision with confirmed financing.
The announced-versus-operating gap reflects long regulatory permitting timelines, financing complexity in an environment where the Section 45Z credit structure has changed materially, feedstock supply agreement complexity, and technology de-risking requirements for less mature pathways. Australia's July 2026 announcement of A$32 million in support for a forest-waste-to-renewable-methanol-to-SAF project illustrates the long development chain between feedstock source and deployable SAF volume.
7.4 — Oil Price Volatility and the Dynamic Premium
FINDING: S&P Global's March 2026 assessment data shows the European HEFA SAF premium fell from $1,463.25/t to $1,139/t within a two-week window as conventional jet-fuel prices rose faster than SAF prices — a $324.25/t premium compression driven entirely by the fossil fuel price, not by any change in SAF production economics.
SO WHAT: A significant portion of SAF premium volatility in any given quarter is driven by conventional jet-fuel price movements rather than SAF cost improvements — which means airlines cannot interpret a narrowing premium as evidence that their long-run SAF cost problem is improving unless they also confirm that SAF's absolute price has fallen.
NOW WHAT: Airlines should monitor both the absolute SAF price and the premium simultaneously — and build procurement models that distinguish between premium movements driven by SAF cost changes and those driven by conventional fuel price changes, as the implications for contracting strategy differ substantially.
7.5 — Policy Fragmentation: What Happens When Markets Move at Different Speeds
FINDING: The six markets analysed in this report have different 2030 SAF targets ranging from 0% (no US federal mandate) to 10% (UK) — different compliance mechanisms from mandates to incentives to levies — and different data transparency levels that make effective airline cost comparison across markets structurally difficult.
SO WHAT: A global airline operating across the EU, UK, US, China, India, and Singapore carries six structurally different SAF cost exposures — and policy changes in any one market (such as the US Section 45Z modification post-2025) can materially shift the global economics of SAF supply and pricing.
NOW WHAT: Airlines should not design a single global SAF procurement strategy; they should build market-specific SAF cost models for each regulatory environment and manage their aggregate SAF position as a portfolio of geographically distinct exposures.
SAF Procurement and Investment Strategy: When to Contract, When to Wait, When to Invest Upstream
DIRECT ANSWER Airlines with EU or UK mandate exposure face a binding SAF obligation that current production cannot satisfy — 6% by 2030 in the EU and 10% by 2030 in the UK, against a 2026 global SAF supply of just 0.8% of total consumption. The decision to sign long-term offtake agreements now versus waiting turns on three variables: mandate compliance exposure by route network, risk tolerance for SAF price movements, and the airline's view on the 2030 cost trajectory. Indexed offtake structures mitigate the binary risk in either direction, linking the SAF price to a market variable rather than fixing it absolutely.
8.1 — The Four Procurement Strategies and Their Risk Profiles
FINDING: There are four principal SAF procurement strategies available to airlines — spot procurement, long-term fixed offtake agreement, indexed offtake, and hybrid structures — each with a distinct profile across price risk, supply risk, compliance risk, and 2030 cost optionality.
SO WHAT: The optimal procurement strategy differs by airline type — a European full-service carrier with heavy EU mandate exposure faces a different risk calculus than a US low-cost carrier with no federal mandate obligation and significant crude-oil price sensitivity in its cost base.
NOW WHAT: Airlines should map their specific mandate exposure by route network, apply their stated fuel-price risk tolerance, and select a procurement structure from the GFJ SAF Procurement Decision Matrix below before any formal supply negotiation begins.
GFJ SAF Procurement Decision Matrix — Five Strategies Compared
Strategy | Price Risk | Supply Risk | Compliance Risk | 2030 Cost Upside | Best Suited For |
Spot procurement | High (market price every purchase) | High (no volume guarantee) | High (no supply certainty) | Highest (if prices fall) | Airlines with no mandate exposure; tactical top-up purchasing |
Long-term fixed offtake | Low (locked price) | Low (volume guaranteed) | Low (supply secured) | Low (locked in if prices fall) | Compliance-driven airlines prioritising cost certainty over optionality |
Indexed offtake | Medium (SAF linked to jet fuel or index) | Low (volume secured) | Low (supply secured) | Medium (moves with market) | Large airlines balancing supply certainty and downside participation |
Hybrid fixed/indexed | Medium-Low | Low | Low | Medium | Airlines with mixed mandate/non-mandate route exposure |
Upstream equity investment | High (capital at risk) | Very Low (own production) | Very Low (controls supply) | Highest (participates in cost reduction) | Strategic leaders with capital capacity — Airbus/Cathay and Air Canada/Airbus model |
8.2 — Contract Structure: Fixed vs Indexed vs Hybrid
FINDING: A fixed-price SAF offtake agreement provides maximum cost predictability for the airline but eliminates participation in any SAF cost reduction that occurs before the contract expires — while an indexed structure linked to conventional jet-fuel price maintains the airline's exposure to the relative premium rather than the absolute SAF price, partially replicating the dynamic of a spot position.
SO WHAT: Neither structure is universally superior — the choice is a bet on the direction of two separate price variables (SAF absolute price and conventional jet-fuel price) and must be taken with an explicit view on both, not as a default preference.
NOW WHAT: Airlines should model their break-even analysis for fixed versus indexed structures across at least three crude-oil price scenarios — approximately $60/bbl, $80/bbl, and $100/bbl — before committing to a contract structure for 2027 onwards.
Risk-transfer in SAF contracts extends beyond price to feedstock risk and delivery risk. An airline in a long-term HEFA offtake agreement should identify whether feedstock cost increases are passed through to the airline or absorbed by the producer — since UCO price escalation could make a nominally fixed-price contract effectively variable through force majeure or renegotiation clauses. Long-term SAF offtake contracts share structural characteristics with power purchase agreements — the analytical frameworks documented in GFJ's Corporate PPA 2027 report offer relevant precedents: greenfueljournal.com/post/corporate-ppa-2027
8.3 — The Upstream Investment Model: What Cathay and Air Canada Signal
FINDING: Both the Airbus-Cathay Group co-investment (up to $70 million, October 2025) and the Air Canada-Airbus initiative (approximately CAD 13.7 million, July 2026) represent a model in which airlines invest upstream in SAF production rather than relying entirely on spot or contracted purchases — sharing production cost risk in exchange for supply certainty and potential long-run cost advantage.
SO WHAT: The upstream investment model is appropriate for airlines with the capital capacity and long-term supply need to justify the investment — it demonstrates that the airline industry is beginning to treat SAF supply security as an infrastructure problem rather than a commodity purchasing problem.
NOW WHAT: Airlines assessing upstream co-investment should evaluate the minimum capital commitment required to secure meaningful supply access, the appropriate partner profile (aircraft manufacturer, fuel company, specialist SAF developer), and the jurisdictions offering the most favourable production economics and policy support.
8.4 — The GFJ SAF Procurement Decision Framework
FINDING: The optimal SAF procurement strategy for any airline is determined by the interaction of three variables: its aggregate mandate exposure by route network and geography, its capital availability for upstream investment, and its stated risk appetite for fuel price and supply variability.
SO WHAT: Airlines that have not explicitly mapped all three variables cannot rationally select a SAF procurement structure — they are making a financial commitment without an adequate analytical basis.
NOW WHAT: Build the mandate-exposure map first, the capital envelope second, and the risk-tolerance framework third — then select a procurement structure from the Decision Matrix that satisfies all three constraints simultaneously.
The GFJ Procurement Decision Framework is a sequence, not a menu. The framework requires mandate exposure quantification (which routes, which volumes, which regulatory deadlines), capital envelope assessment (can upstream investment be justified within the airline's balance sheet), and risk-tolerance definition (what is the acceptable range of fuel cost outcomes). Only with all three defined can a contract structure be rationally selected.
