本研究は、国際石炭貿易と物品・サービス貿易に伴うCO2排出と大気汚染による健康被害を1992～2020年にわたり定量化した。石炭貿易では45.4Gtの累積CO2排出と年7.5万人の超過死亡、物品・サービス貿易では60.6Gtと年16.7万人の超過死亡が生じている。先進国と中国では輸入由来の影響がピークを迎えたが、新興国では増加傾向にあり、南南貿易の拡大がリスクを高める可能性がある。
English
This study quantifies coal-related CO2 emissions and health damages embodied in international coal trade and goods/services trade from 1992 to 2020. Coal trade contributed 45.4 Gt cumulative CO2 and 74,700 annual deaths; goods/services trade contributed 60.6 Gt and 166,600 deaths. Impacts have peaked in developed regions and China but are rising in emerging economies, with South-South trade intensifying risks.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の排出削減策やサプライチェーン管理において、石炭関連の輸入排出量の実態把握は重要。本研究はScope 3排出の評価や国際協調の必要性を示唆し、日本企業のTCFD開示やサプライチェーン排出削減目標（SBT）にも活用可能。
In the global GX context
This paper offers a critical lens for global climate cooperation by revealing the unequal distribution of coal-related emissions and health burdens through trade. It strengthens the case for including health co-benefits in transition finance and supports the development of consumption-based emission inventories under the Paris Agreement.
👥 読者別の含意
🔬研究者:Provides a novel integrated framework combining MRIO, GEOS-Chem, and exposure-response modeling to quantify trade-embodied emissions and health impacts, useful for carbon accounting and climate-health research.
🏛政策担当者:Highlights the need for equitable international cooperation and considerations of trade-induced health impacts in climate policies, supporting phase-out of coal and just transition mechanisms.
📄 Abstract（原文）
Coal combustion contributes greatly to the level of CO2 emissions, air pollution, and health burdens. International trade classifies coal extraction, coal combustion, and the consumption of goods and services separately. A lack of comprehensive analyses of trade-embodied CO2 emissions and health damages limits our understanding of the regional responsibilities of these impacts across the chain of coal supply and use. Here we developed an integrated framework combining global coal trade matrices, a multiregional input-output model, GEOS-Chem simulations, and exposure-response modeling to trace coal-related impacts embodied in trade. We show that international coal trade accounted for 45.4 Gt of cumulative CO2 emissions and an annual average of 74,700 deaths attributable to fine particle exposure during 1992–2020, while international goods and services trade contributed more, at 60.6 Gt and 166,600 annual cases, respectively. Major exporters of coal (Australia and South and Southeast Asia) and importers of associated goods and services (the United States and Western Europe) are responsible for substantial impacts outside their territories. Although imported emissions and associated mortality have peaked in developed regions and China, they keep growing in emerging economies. Expanding South–South trade may further intensify these risks. The findings support equitable international cooperation on phasing out coal to achieve climate and environmental health objectives.
