📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では水産物のカーボンフットプリント表示が進んでおり、本レビューの方法論的課題整理は国内の標準化議論に示唆を与える。SSBJや有報での開示要求が強まる中、製品レベルでの算定手法の一貫性は実務上の重要課題である。
In the global GX context
This review addresses global challenges in product carbon footprint standardization, directly relevant to the GHG Protocol and ISO frameworks. Its focus on seafood adds to sector-specific insights needed for Scope 3 reporting and supply chain decarbonization. The identified obstacles, such as system boundary discrepancies, are key issues in international carbon accounting harmonization.
👥 読者別の含意

📄 Abstract（原文）
This paper discusses current methodologies for measuring carbon footprints within the food industry, with a particular focus on seafood and seafood-based products. Key approaches, including life cycle assessment, are discussed. The carbon footprint methodology estimates total greenhouse gas emissions across the entire life cycle of a product, from the initial extraction of the raw materials up until the final disposal and serves as an essential tool for evaluating environmental consequences and supporting sustainable practices. However, several obstacles exist, including discrepancies in system boundaries, functional units, regionality, time frames, data availability and reliance on emission factors. These issues complicate the identification of hotspots, framework standardization, and limit comparability of results across studies. This review further evaluates major carbon accounting standards at both organisational and product levels, such as ISO 14064, the GHG Protocol, PAS 2050, and ISO 14067. In addition, it highlights key factors influencing carbon footprint assessments, including greenhouse gas selection, system boundary definition, data collection, and emission quantification. Hence, the study emphasises the need for greater consistency, transparency, and standardisation in carbon footprint methodologies to improve reliability and support effective emission reduction strategies in the seafood sector.
