日本語

本研究は、乳幼児用シリアル（CERELAC®）を対象にISO 14040/44準拠のライフサイクルアセスメント（LCA）を実施し、スコープ1、2、3排出量を定量化した。結果、総排出量の94.3%がスコープ3に起因し、製品使用（44.7%）と購入財・サービス（36.9%）が主要な貢献因子である。再生農業や原材料最適化、包装変更、物流改善、消費者関与などのシナリオ分析により、ライフサイクル排出量の大幅削減可能性を示した。

English

This study conducts an ISO 14040/44-compliant cradle-to-grave LCA on CERELAC® infant cereal, quantifying Scope 1, 2, and 3 emissions. Scope 3 emissions dominate at 94.3% of total, with product use (44.7%) and purchased goods and services (36.9%) as key hotspots. Scenario analysis demonstrates significant reduction potential through regenerative sourcing, ingredient optimization, packaging redesign, logistics improvements, and consumer engagement.

In the global GX context

This paper provides a robust case study on Scope 3 emissions in agri-food systems, aligning with global disclosure frameworks (ISSB, TCFD) that require supply chain transparency. Its scenario-based approach offers transferable insights for companies aiming to meet net-zero targets through actionable supply chain interventions.

👥 読者別の含意

🔬研究者:Provides a granular LCA methodology for Scope 3 hotspot analysis in processed foods, useful for comparative studies and scenario modeling.

🏢実務担当者:Offers concrete mitigation pathways (regenerative sourcing, ingredient optimization) for food companies to reduce supply chain emissions.

🏛政策担当者:Highlights the need for policies targeting consumer-phase emissions and upstream agricultural inputs in food system decarbonization.

📄 Abstract（原文）

Agri-food systems account for a substantial share of global greenhouse gas (GHG) emissions, with a significant proportion arising from upstream supply-chain activities beyond direct operational control. In this context, effective decarbonization requires systematic assessment of emissions across all life-cycle stages. This study applies an ISO 14040/44-compliant cradle-to-grave Life Cycle Assessment (LCA) to CERELAC® infant cereal, a processed dairy-based product, to quantify Scope 1, Scope 2, and Scope 3 emissions and identify mitigation pathways across the full product life cycle. Results indicate that Scope 3 emissions account for 94.3% of total product emissions, with product use (44.7%) and purchased goods and services (36.9%) as the primary contributors. Upstream agricultural inputs—particularly milk powder—emerge as the dominant hotspot due to methane emissions and energy-intensive processing. Scenario-based evaluation suggests that regenerative sourcing, ingredient optimization, packaging redesign, logistics improvements, and consumer-phase engagement could significantly reduce life cycle emissions. The findings demonstrate how product-level LCA can operationalize Scope 3 decarbonization strategies in processed food systems, bridging corporate net-zero ambitions with actionable supply chain interventions. These results provide transferable insights for cleaner production transitions within the agri-food sector.
