English
This chapter reviews the environmental impacts and GHG reduction potential of sustainable aviation fuel (SAF). It covers life-cycle assessment methodologies, land-use trade-offs, certification schemes, and spatially explicit tools. It highlights the need for comprehensive sustainability criteria beyond GHG emissions to avoid unintended consequences in aviation decarbonization.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、航空分野の脱炭素化目標（2030年までにSAF普及10%）や「2030年頃」の商用運航開始に向けた実証が進む。本稿のLCA手法や認証基準の議論は、日本企業が国際的なSAFサプライチェーンに参画する際の環境評価の参考となる。
In the global GX context
With aviation decarbonization targets tightening globally (e.g., ICAO CORSIA, EU ReFuelEU), this chapter provides a critical overview of SAF sustainability metrics and certification. Its discussion of trade-offs between GHG reductions and other environmental impacts informs both policymakers and fuel producers in designing robust frameworks.

📄 Abstract（原文）
The recent boost for producing and using alternative jet fuels (AJFs) – or sustainable aviation fuel (SAF) considering specific criteria – is essentially supported by the ambitious decarbonisation targets of the aviation sector. In addition to economic and technological obstacles for scaling-up a new supply-chain, methodological issues, especially environmental and social aspects, can be a challenge. “What” must be measured and “how” to do it are strategic issues for decision making. The first sustainability criteria for SAF were based on greenhouse gases (GHGs) accounting along the SAF life cycle and the land use. Other criteria must be considered aiming to promote an effective and sustainable energy transition in the aviation sector. This chapter is divided into four sections. The first explores the GHG reduction potential of alternative jet fuels in different methodologies, including possible trade-offs with other environmental impact categories. The second and third sections present a general overview of the sustainability risks related to SAF production and the current certification schemes associated with SAF production. Finally, the last section briefly explores two initiatives for using spatially explicit tools in environmental analysis.
