バイオ炭の普及に向けた世界の政策手法（金融・非金融・研究開発支援）を整理し、米国北東部を対象に入力補助金や税額控除が生産コストに与える影響を技術経済的ブレークイーブンモデルで定量化した研究。高い生産・参入コストには市場創出政策や原料調達の規制明確化が不可欠と結論づけ、豪州の炭素クレジット制度や日本のR&D支援などを成功例として挙げる。北東部には科学的信頼の醸成、カナダとの地域ネットワーク構築、複合的政策の導入を提言する。
English
This study reviews global biochar policies (financial, non-financial, R&D) and builds a techno-economic breakeven model to quantify how input subsidies and tax credits affect production costs in the Northeast US. It finds high production and entry costs require market-creation policies and regulatory clarity for feedstock procurement, citing Australia's carbon credits and Japan's R&D support as successful models. It recommends the Northeast US build scientific trust, foster a regional network with Canada, and combine incentives, regulatory adjustments, and continued R&D for commercialization.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
バイオ炭は炭素除去（CDR）クレジットとしてScope 3削減やGX推進に資するが、本稿は日本の制度・企業実務への直接的な示唆は限定的。日本のR&D支援策が国際比較の一事例として言及される点は、国内の炭素除去政策の対外発信材料になり得る。
In the global GX context
Biochar as a carbon dioxide removal (CDR) pathway is increasingly relevant to voluntary carbon markets and corporate net-zero strategies under TCFD/ISSB disclosure. This paper's policy-instrument taxonomy and breakeven modeling offer a transferable framework for jurisdictions designing CDR incentives, though its empirical focus is regional (Northeast US).
👥 読者別の含意
🔬研究者:バイオ炭の技術経済的ブレークイーブン分析と政策手法の類型化は、CDR政策研究の比較枠組みとして参考になる。
🏢実務担当者:バイオ炭の調達・投資判断において、補助金や税額控除が生産コストに与える影響を定量的に把握する材料となる。
🏛政策担当者:バイオ炭普及には市場創出政策と原料調達の規制明確化を組み合わせた複合的政策が有効であることを示す。
📄 Abstract（原文）
Abstract Biochar is a carbon-rich material created through the pyrolysis of organic biomass, offering multiple environmental benefits for soil improvement and climate change mitigation. While its use is expected to grow, particularly in the Northeast United States, widespread adoption faces challenges, including social distrust, economic hurdles, and high production costs. This study uses a structured narrative review of global policies to identify instruments such as financial, nonfinancial, and research & development that could inform decision-makers on biochar policy. We also developed a techno-economic breakeven model to quantify the impact of policies like input subsidies and tax credits on production costs in the Northeast United States. Our analysis shows that high production and entry costs require strategic policy interventions, including market-creation policies and regulatory clarity for feedstock procurement. Global examples showcase varied successful strategies, ranging from Australia’s carbon credit systems to Japan’s R&D support. We recommend that the Northeast US establish scientific certainty and trust, foster a regional network with Canada, and implement multi-instrument strategies that combine incentives, regulatory adjustments, and continued R&D to drive large-scale commercialization. These findings provide a roadmap for policy makers to help biochar reach its full potential in the region.
