中国江蘇省の100MW陸上風力発電所を対象に、プロセスベースのLCAを実施。ライフサイクルGHG排出原単位は24.6gCO2-eq/kWh。カーテールメント削減とリサイクル改善が排出削減に有効であり、タワー素材の選択はリサイクル率に依存する。低炭素調達やグリーンサプライチェーン、系統連携の重要性を指摘。
English
A process-based LCA for a 100MW onshore wind farm in China finds life-cycle GHG intensity of 24.6 g CO2-eq/kWh. Curtailment reduction and improved end-of-life recycling are key mitigation levers. The study also highlights low-carbon procurement, green supply chain, and coordinated grid planning for wind projects.

日本のGX文脈において
日本でも風力発電のライフサイクル評価は重要だが、本論文は中国の実証データと詳細な工程分解を提供。日本の風力LCAやSSBJのスコープ3検討に参考となる。ただし、日本の電力構成や廃棄物処理体系の違いに注意。
In the global GX context
As LCA becomes central to green claims, this study provides granular data on wind farm emissions and mitigation levers. It reinforces the importance of end-of-life recycling and curtailment reduction—relevant for global wind LCA standards and transition plan integrity under ISSB/CSRD.

📄 Abstract（原文）
Life cycle greenhouse gas (GHG) accounting is increasingly required to substantiate the climate value of wind power beyond “zero-emission” operation, especially under China’s dual-carbon targets. Robust estimation of life cycle GHG emission intensity and the identification of actionable mitigation levers are therefore important for credible transition planning. In this study, a process-based life cycle assessment (LCA) was conducted for a representative 100 MW onshore wind farm in Gaoyou, Jiangsu Province, China, following ISO 14040/14044. To enhance engineering relevance, the construction and installation phase was modeled in a refined manner by decomposing it into road, wind-turbine, booster-station, and transmission-line engineering and further into unit processes. The results show that the overall life cycle GHG emission intensity of the studied wind farm is 24.6 g CO2-eq/kWh. Scenario analysis further indicates that reducing curtailment and improving end-of-life recycling are effective pathways to lower emission intensity, while the net advantage of hybrid versus steel towers depends on recycling performance when end-of-life credits are included. The study also summarizes practical implications for low-carbon equipment/material procurement and green supply-chain governance, low-carbon construction and logistics, coordinated “source–grid–load–storage” planning to curb curtailment, and more standardized and comparable life cycle carbon accounting for wind projects in China.
