茶アグリフードシステムの温室効果ガス排出源と炭素フットプリント測定方法を系統的にレビュー。電力・エネルギーが主要排出源で、化学肥料の過剰使用や加工時の石炭・薪も寄与。消費段階が最大の環境負荷（47%）を占める。有機肥料や廃棄物堆肥化などの適応・緩和策を提案。
English
This systematic review of 60 articles examines the carbon footprint of tea agrifood systems, identifying electricity and energy as primary emission sources, followed by fertilizer overuse and coal/firewood in processing. Consumption accounts for 47% of environmental footprint. Proposes mitigation strategies like energy efficiency, organic fertilizers, and composting.

📄 Abstract（原文）
Background This study contributes to the growing interest and the need to enhance overtime transformational changes in the agrifood systems through understanding the environmental impacts of the tea agrifood system operations and identifying greenhouse gas emissions channels for improving and designing sustainable solutions to achieve SDG 13 (Climate action). Objectives It explores the main sources of greenhouse gas emissions (GHG) and methods used to measure carbon footprint and global warming potential. The study identifies different adaptation and mitigation strategies that reduce emissions from the tea agrifood system. Methods Focusing on carbon footprint as the main factor in environmental sustainability and agrifood system resilience, 60 articles were systematically analyzed using MAXQDA software. Results The study found that the life cycle assessment of tea agrifood systems was highly conducted using SimaPro, different unspecified tools, and spreadsheets under ISO14040:2006, ISO14044, and PAS 2050:2011 impact evaluation standards. Moreover, electricity and energy were revealed as the leading sources of carbon emissions (CO 2 ), followed by the overuse of chemical fertilizers, which emit other greenhouse gasses (CH 4 and N 2 O) at the cultivation stage, and the use of coal and firewood in the processing and packaging stages. Likewise, the highest environmental footprint was due to consumption activities (47%), processing (27%), cultivation (17%), and packaging (9%). Conclusion The study highlighted that various adaptation and mitigation strategies, including improving energy use efficiency, use of organic fertilizers, and waste composting from tea processing, can reduce carbon footprints, improve environmental sustainability, and enhance resilient, greener agrifood systems.
