📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではバイオマス発電のFIT認定やカーボンニュートラル性が議論されており、LCAの標準化は政策評価や企業報告の信頼性向上に寄与する。ただし本稿は特定の日本事例ではなく一般論のため、直接的な示唆は限定的。
In the global GX context
Bioenergy LCA is critical for credible carbon accounting and policy, especially as the EU and global frameworks (e.g., RED II, ISSB) demand robust environmental footprinting. This review provides a methodological foundation but lacks empirical case studies or regulatory specifics.

📄 Abstract（原文）
Life Cycle Assessment (LCA) is a systematic, internationally standardized (ISO 14040/14044) methodology for quantifying the full environmental footprint of bioenergy systems, from feedstock production to end-of-life. It provides an essential evidence base for policy, moving beyond simplistic carbon neutrality claims by assessing multiple impact categories like global warming potential, acidification, and land use. Despite its importance, bioenergy LCA faces significant challenges that undermine the comparability and credibility of studies. These include inconsistencies in system boundary definitions, varied functional units, poor data quality, and the frequent omission of uncertainty analysis. Two distinct methodological frameworks exist: attributional LCA (ALCA), which attributes a share of existing environmental burdens to a product, and consequential LCA (CLCA), which models the system-wide consequences of a decision, making it better suited for policy analysis. Accurately accounting for complex factors like biogenic carbon flows and indirect land-use change (ILUC) remains a critical hurdle. To create a more holistic view, the scope of assessment is expanding. Social Life Cycle Assessment (S-LCA) evaluates impacts on stakeholders like workers and communities, while Life Cycle Sustainability Assessment (LCSA) integrates environmental, social, and economic pillars. Efforts like NREL's LCA Harmonization Project aim to reduce variability in results to provide more reliable benchmarks. The future of bioenergy LCA points towards prospective, dynamic modeling and integration with digital tools like Product Passports to support a truly sustainable energy transition.
