本レビューは81の文献を統合し、SAF導入の意思決定を4つの論点（生産可能性、資金調達、契約と市場支配力、環境主張の配分）に整理する。私的・社会的採用ギャップの概念を用い、炭素価格・義務・補助金・証書が不確実性や容量制約下で異なる効果を持つことを示す。段階的政策枠組みとして、まずプロジェクトリスク低減と能力構築、次に競争によるコスト顕在化と限定的取引、最終的に検証済み性能と競争政策への移行を提案する。
English
This review synthesizes 81 sources to frame SAF deployment around four decision loci: producible volumes with verified climate benefits, financing and demand certainty, contract and market-power allocation, and environmental claim allocation across jurisdictions. It introduces the private-social adoption gap and shows carbon prices, mandates, subsidies, and certificates behave differently under uncertainty and capacity limits. A stage-based policy framework is proposed: reduce project risk and build capacity, then reveal costs through competition and controlled trading, and finally rely on verified performance and competition policy.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は航空脱炭素とSAF国産化を重要政策課題としており、本稿の段階的枠組みは経済産業省・国交省のSAF政策設計や企業の調達・投資判断に示唆を与える。特に環境主張の配分と証書設計は、日本企業のScope 3・GHG算定や国際競争力に直結する。
In the global GX context
SAF is central to aviation decarbonization under ICAO CORSIA and national net-zero strategies. This review's stage-based framework and treatment of environmental claim allocation speak directly to global disclosure debates (TCFD/ISSB) on how aviation emissions and SAF certificates are accounted and claimed across jurisdictions.

📄 Abstract（原文）
Deploying sustainable aviation fuel (SAF) involves more than paying a premium over fossil jet fuel. Fuel pathways differ in production cost, life-cycle emissions, resource needs, and the quantity that can realistically be supplied. Investment also depends on policy stability, contracts, airport infrastructure, airline competition, and rules for environmental claims. This review brings together 81 sources: 66 peer-reviewed studies, two working papers, five foundational theory contributions, and eight institutional documents. Cross-study comparison identifies four recurring decision loci, which we express as practical questions: which fuels can be produced in useful quantities with verified climate benefits; how uncertain projects obtain finance and dependable demand; how contracts and market power divide costs, risks, access, and profits; and how fuel and environmental claims are allocated across airports and jurisdictions. We connect these questions with the private-social adoption gap, defined as the difference between the net value to society and the net value faced by an airline or buyer. The evidence shows that a low selling price does not necessarily mean low-cost emissions reduction when supply is limited or inputs have valuable uses elsewhere. Carbon prices, mandates, subsidies, and certificates also work differently under uncertainty, capacity limits, market power, and traffic response. Flexible accounting can reduce matching and logistics costs. Whether it increases net social value depends on whether it causes extra supply, prevents duplicate claims, preserves competition, and avoids shifting benefits away from smaller regions. We therefore propose a stage-based policy framework: first reduce project risk and build operating capacity; then use competition to reveal cost and allow controlled trading; and finally rely more on verified performance, competition policy, and declining public support.
