日本語
本研究は、牛革および植物由来の代替皮革（ビーガンレザー）のカーボンフットプリントをメタ分析と新たなトップダウン手法で再評価。報告されている牛革の生産段階排出量が従来の2倍以上となり、牛革全体のフットプリントは187.1 kg CO2 eq/kg finished leatherと、ビーガンレザーの約12倍に達する。本研究はLCAの限界を克服し、製品設計や調達判断に重要な示唆を与える。
English
This study reassesses the carbon footprint of bovine leather and vegan alternatives using meta-analysis and a novel top-down method. The revised farming-phase emissions are more than double prior estimates, resulting in a total bovine leather footprint of 187.1 kg CO2 eq/kg finished leather—over twelve times that of vegan leather at 14.9 kg CO2 eq/kg. The findings address LCA limitations and inform sustainable material sourcing.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも、SSBJ基準に基づくサプライチェーン排出量（Scope3）の開示が進む中、繊維・アパレル業界の原材料選択に直接影響するデータ。特に輸入皮革に依存する日本企業にとって、本研究成果はカーボンフットプリント算定の精緻化に寄与する。
In the global GX context
Globally, this paper is critical for fashion and textile sectors facing TCFD/ISSB-aligned disclosure and transition to lower-carbon materials. The revised carbon footprint estimates provide robust benchmarks for LCA practitioners and policymakers designing carbon accounting standards for consumer goods.

📄 Abstract（原文）
High Resolution Image Download MS PowerPoint Slide Product designers and manufacturers lack robust and regionally representative information on the greenhouse gas (GHG) or “carbon” footprints of leather textiles. This study presents a meta-analysis of carbon footprints from life-cycle assessments (LCAs) of bovine leather and some increasingly common nonanimal or “vegan” leather alternatives. We also present a novel “top-down” method for estimating GHG emissions from bovine leather’s farming phase, utilizing data from the UN Food and Agriculture Organization (FAO) and economic allocation literature to address common LCA limitations. The revised analysis produces a farming-phase carbon footprint that is more than double that of prior estimates. Consequently, the total bovine leather carbon footprint is 187.1 (148.1−214.5 IQR) kg CO 2 eq/kg finished leather, more than twelve times greater than that of vegan leather at 14.9 (10.1−19.5 IQR) kg CO 2 eq/kg finished leather.
