本研究は、航空脱炭素化におけるバイオ炭による炭素除去と持続可能な航空燃料（SAF）による化石燃料置き換えの両経路を比較。技術経済評価を調和させ、現在のバイオ炭コストは約177 USD/tCO2、廃棄物由来SAFは約448 USD/tCO2であり、バイオ炭が短期的、SAFが長期的な選択肢であることを示した。
English
This study compares biochar carbon removal and sustainable aviation fuel (SAF) for aviation decarbonization. It finds commercial biochar has a median abatement cost of ~177 USD/tCO2, while waste-derived SAF costs ~448 USD/tCO2, suggesting biochar as a near-term option and SAF for longer-term. The analysis provides empirical cost benchmarks for biomass allocation decisions.

📄 Abstract（原文）
Waste biomass can deliver climate mitigation through two fundamentally different routes: durable carbon removal via biochar and fossil-jet displacement via sustainable aviation fuel (SAF). We harmonize published techno-economic assessments to a common 2024 delivered-to-market basis and compare both pathways as climate-service abatement cost (USD tCO 2 − 1 removed or avoided). For biochar, we combine an empirical cost-capacity relationship with audited net-removal factors. For SAF, we distinguish the commercially dominant waste-lipid route from the waste- and residue-derived pathways needed for larger long-run scale. Commercial biochar systems currently deliver a median abatement cost of about 177 USD tCO 2 − 1 (5th–95th percentile: 111–497 USD tCO 2 − 1 ), while waste-derived SAF centers near 448 USD tCO 2 − 1 . Current SAF supply is still overwhelmingly lipid-based, whereas the lignocellulosic and municipal-solid-waste routes needed for larger long-term aviation abatement remain earlier in commercialization. These differences suggest complementary timelines: biochar is a near-term removal option, while SAF remains a longer-term aviation decarbonization pathway.
