中国のネットゼロ経路（2020-2060年）を対象に、DACCSの大規模導入が大気汚染関連死亡に与える影響を36kmグリッドで評価。DACCSは累計175万人の追加死亡を引き起こし、発展地域の健康コベネフィットを不均衡に減少させる一方、地域間の死亡率格差は縮小。排出権取引の活性化が主因で、河南省や河北省で損失が大きい。
English
This study assesses the grid-level health cobenefits of DACCS in China's net-zero pathway (2020-2060). Large-scale DACCS deployment causes an additional 1.75 million premature deaths cumulatively and disproportionately reduces health cobenefits in developing regions, while narrowing regional mortality gaps. Emissions trading amplifies these effects, with Henan and Hebei losing 0.13 and 0.12 million avoided deaths respectively.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではDACCSの導入検討が進むが、健康影響の地域格差を考慮した政策設計は未整備。本研究成果は、日本のカーボンニュートラル戦略におけるCDR技術の位置づけや、地域間の公平性を考慮した排出削減政策の立案に示唆を与える。
In the global GX context
Globally, this paper provides critical evidence for integrating health considerations into CDR deployment strategies, aligning with the Paris Agreement's equity principles and the growing focus on just transition. It highlights the trade-offs between carbon removal and air quality, informing international climate policy and carbon pricing mechanisms.

📄 Abstract（原文）
Abstract Direct air carbon capture and storage (DACCS) is an emerging carbon dioxide removal (CDR) technology, but it may reduce the health cobenefits of climate mitigation by substituting for fossil-fuel phase-out that would otherwise reduce air pollutant emissions. The heterogeneity of these effects, however, remains unclear. By assessing grid-level (36 km2) air pollution-related mortality in China’s pathway to net-zero CO2 emissions over 2020–2060, we show that, in addition to cumulatively causing an additional 1.75 million premature deaths, large-scale DACCS deployment exacerbates health inequity by disproportionately reducing health cobenefits in developing regions, while improving health equality by closing the gap among regional mortality rates. These impacts are largely attributed to more active emissions trading promoted by the development of DACCS. Despite increases in carbon emissions allowances in both developing and developed regions, the losses in health cobenefits are larger in developing regions such as Henan and Hebei, corresponding to 0.13 million and 0.12 million fewer avoided premature deaths, respectively. Our results support how health-considered policy can be incorporated into CDR deployment strategies to enhance health cobenefits and promote equitable health outcomes.
