本研究は、インドでの綿花栽培からスペインでの小売流通までのサプライチェーンを対象に、認証オーガニック・フェアトレード綿Tシャツと従来綿Tシャツの環境影響を比較したLCAである。綿花栽培段階ではGWPが82.5%、水消費が98.7%、生態毒性が99.9%削減されるが、サプライチェーン全体ではGWP 26.9%、水消費23.8%の削減にとどまる。認証と農法改善だけでは産業加工や物流の負荷を克服できず、消費削減の必要性を示す。
English
This study compares the environmental performance of certified organic and fair-trade cotton T-shirts versus conventional ones using a cradle-to-retail-gate LCA, from cotton cultivation in India to retail in Spain. While cotton cultivation shows dramatic reductions (GWP -82.5%, water -98.7%, ecotoxicity -99.9%), full supply chain reductions are more moderate (GWP -26.9%, water -23.8%). Certification alone cannot offset industrial processing and logistics burdens, highlighting the need for reduced consumption.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではサプライチェーン排出量（Scope 3）の開示が進む中、繊維産業のLCA事例は国内企業の調達判断や環境報告に参考となる。特に、認証制度の効果を定量的に示す点は、サステナビリティ報告のエビデンスとして有用。
In the global GX context
This LCA provides empirical evidence on the environmental benefits of certified organic and fair-trade supply chains, relevant to global disclosure frameworks like CSRD and SEC climate rules that require supply chain emissions reporting. It underscores that certification alone is insufficient, informing corporate strategies and policy on sustainable textiles.

📄 Abstract（原文）
The current socioeconomic model has driven the rapid expansion of the fashion industry, which now accounts for up to 10% of global greenhouse gas emissions. However, textile production is geographically unbalanced, with a large share of environmental impacts occurring in the Global South. Certified organic and fair-trade supply chains are frequently presented as more sustainable alternatives; however, previously published studies report highly heterogeneous results, with deviations reaching up to 172%. To contribute to this debate, this study compares the environmental performance of a certified organic and fair-trade cotton T-shirt with that of its conventional cotton counterpart. Both supply chains were modelled from cotton cultivation in India to retail distribution in Spain using a cradle-to-retail-gate Life Cycle Assessment. Primary inventory data were obtained from the certified supply chain and complemented with secondary data, while environmental impacts were assessed using the ReCiPe 2016 Midpoint (H) method. Although 18 midpoint impact categories were calculated, Global Warming Potential, Terrestrial Ecotoxicity Potential, Freshwater Ecotoxicity Potential and Water Consumption Potential were selected for detailed analysis. The greatest environmental improvements occur during cotton cultivation, where Global Warming Potential decreases by 82.5%, Water Consumption by 98.7%, and both Freshwater and Terrestrial Ecotoxicity by 99.9%. Across the complete cradle-to-retail-gate supply chain, the certified organic and fair-trade model reduces Global Warming Potential by 26.9%, Freshwater Ecotoxicity by 31.6%, Terrestrial Ecotoxicity by 14.7% and Water Consumption by 23.8%, compared with the conventional system. Overall, the results show that the studied certified organic and fair-trade context substantially reduces environmental impacts during cotton cultivation in the Global South. However, the more moderate reductions observed across the complete supply chain indicate that certification and improved agricultural practices alone cannot overcome the environmental burdens associated with industrial processing, energy use and logistics. Therefore, alongside improvements in production systems, reducing overall textile consumption remains essential.
