本研究は、牧草ベースの牛肉生産システムに対し、ゆりかごから墓場までの高分解能LCAを適用した。16の影響カテゴリーを定量化し、メタンと飼料生産が全体の70%超を占めることを発見。土壌炭素貯留が一部の排出を相殺。環境製品宣言を支援するベースラインを提供する。
English
This study applies a high-resolution cradle-to-grave LCA to a pasture-based beef production system, quantifying 16 impact categories. Enteric methane and feed production account for over 70% of total climate change impact. Soil carbon sequestration partially offsets biogenic emissions. The results provide a baseline for Environmental Product Declarations and hotspot identification.

📄 Abstract（原文）
Beef production is widely recognized as a significant contributor to global greenhouse gas emissions, making robust and transparent environmental assessments essential for advancing sustainability within supply chains. This study applies a comprehensive cradle-to-grave Life Cycle Assessment (LCA) to evaluate the environmental performance of beef destined for export, following ISO 14040, ISO 14044 and ISO 14067 standards and the Product Category Rules for meat of mammals. Sixteen impact categories were quantified for 1 kg of vacuum-packed beef using detailed primary data from a pasture-based production system and a representative processing facility. The total climate change impact was 3.27 × 101 kg CO2eq, with enteric methane and feed production jointly responsible for over 70% of overall impacts. Slaughtering and distribution were associated mainly with fossil energy use and ozone depletion, while soil carbon sequestration partially compensated biogenic emissions. The results were consistent with international benchmarks, highlighting the environmental advantages of pasture-based systems, low fertilizer use, and stable land management. Key hotspots were identified in animal growth, feed efficiency, and manure management, with logistics also contributing notably. Overall, the study provides a high-resolution environmental baseline that can support Environmental Product Declarations and guide targeted mitigation strategies across beef supply chains. While the results are derived from a specific pasture-based production system, the study is positioned as a case-study-based application of a high-resolution LCA framework, illustrating how detailed inventories can support environmental benchmarking and hotspot identification without implying statistical representativeness of all beef production systems.
