本レビューは、汚染サイト修復におけるカーボンフットプリント管理の知見を体系的に整理。4つの会計手法（LCA、産業連関分析、IPCC計算、ハイブリッドLCA）を評価し、修復技術間の炭素フットプリントの階層を明らかにした。さらに、精密修復、オンサイト再生可能エネルギー、バイオ炭などの脱炭素戦略を検討し、プロジェクト固有のLCAの重要性を指摘。方法論的課題（排出範囲、体化炭素、時間的境界、不確実性報告）も抽出している。

This review systematically synthesizes knowledge on carbon-footprint management in contaminated-site remediation. It evaluates four accounting approaches (LCA, input-output analysis, IPCC calculation, hybrid LCA) and reveals a conditional carbon-footprint hierarchy among remediation technologies. Emerging decarbonization strategies such as precision remediation, on-site renewable energy, and biochar are assessed. Methodological challenges including emission-scope coverage and embodied carbon are identified as barriers to cross-study comparability.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の土壌汚染対策は厳格な基準があり、修復工事のカーボンフットプリント削減が求められている。本レビューは、SSBJやGXリーグの枠組みでScope3排出源としての修復活動を評価する際の基礎資料となる。特に、LCA手法の選択が結果に与える影響を整理しており、日本の実務者に有用。
In the global GX context
Globally, contaminated-site remediation is an often-overlooked source of emissions in net-zero strategies. This review provides a structured comparison of carbon accounting methods and decarbonization options, directly informing ISSB-aligned disclosure and TCFD scenario analysis for environmental remediation firms. The identified methodological challenges highlight the need for standardized reporting across jurisdictions.
👥 読者別の含意
🔬研究者:Carbon accounting researchers can leverage the comprehensive methodology review and identified research gaps (e.g., temporal boundaries, uncertainty) for future empirical studies.
🏢実務担当者:Remediation firms and environmental consultants can use the comparative carbon-footprint hierarchy and decarbonization strategies to design lower-emission remediation projects and improve sustainability reporting.
🏛政策担当者:Policymakers can reference the review to develop guidelines for integrating carbon-footprint considerations into contaminated-site remediation regulations and incentives.
📄 Abstract（原文）
The remediation of contaminated sites is essential for environmental protection but often carries a substantial carbon footprint due to energy‑intensive processes, material consumption, and transportation logistics. This review systematically synthesizes current knowledge on carbon-footprint management in contaminated-site remediation, focusing on accounting methodologies, comparative technology assessment, key influencing factors, and decarbonization strategies. Four accounting approaches are critically evaluated, namely life cycle assessment (LCA), input-output analysis, intergovernmental panel on climate change calculation, and hybrid LCA, and their applications across site‑specific, regional, and macro scales are examined. A comparative analysis reveals a conditional carbon-footprint hierarchy: nature‑based solutions < optimized in situ physical and chemical treatments < energy‑intensive thermal and ex situ methods. However, reported footprints vary widely even within the same technology due to differences in contaminant type, site geology, treatment intensity, local energy mix, and regulatory context. Emerging decarbonization strategies such as precision remediation, on‑site renewable energy, biochar‑based amendments, green logistics, and decision‑support tools are evaluated in terms of their evidence base, implementation constraints, and associated trade‑offs. Coupling multiple decarbonization strategies can yield synergistic benefits; however, project‑specific LCA is essential for robust evaluation. Additionally, key methodological challenges, including emission-scope coverage, embodied-carbon accounting, temporal-boundary definition, and uncertainty reporting are identified as barriers to cross‑study comparability. This review provides a critical, evidence‑based foundation for researchers, practitioners, and policymakers to align contaminated-site remediation with global carbon-neutrality goals.
