大気汚染が陸域炭素吸収と再生可能エネルギー（太陽光・風力）の潜在量に与える影響を、複数の排出シナリオ下で定量化した研究。北半球全体で年間1.22Gt CO2、中国で0.416Gt CO2の削減ポテンシャルが大気汚染により失われていることを示す。大気質改善が炭素吸収と再エネ潜在量を高める気候緩和の相乗便益を持つと結論づけ、SDGs達成戦略設計への含意を示す。
English
This study quantifies how air pollution alters terrestrial carbon sinks and renewable energy (solar PV, wind) potential under multiple emission scenarios. Air pollution reduces integrated carbon mitigation potential by 1.22 Gt CO2/yr across the Northern Hemisphere, with 0.416 Gt CO2/yr lost in China, and these adverse effects persist in future projections. Air quality improvement thus offers a climate mitigation co-benefit by enhancing carbon uptake and renewable energy potential, with implications for SDG strategies.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は大気汚染規制と再エネ導入を並行して進めており、大気質改善が再エネ潜在量や森林吸収源（J-クレジット、GX-ETS）に与える相乗効果は、環境省・経産省の政策設計や企業の再エネ調達戦略に示唆を与える。
In the global GX context
While not a disclosure-framework paper, it strengthens the scientific case that air quality and climate policy are synergistic — relevant to ISSB/TCFD physical-risk narratives and to national decarbonization pathway design where co-benefits are increasingly cited in NDCs and transition plans.

📄 Abstract（原文）
Terrestrial carbon sink enhancement and energy system transformation to low-carbon energy are two complementary carbon mitigation pathways. The effectiveness of these pathways can be altered by air pollution via its effects on meteorological conditions. However, how air pollution affects the overall performance of integrated carbon mitigation through these pathways remains unclear. Here we systematically quantify the influences of air pollution on terrestrial carbon sinks and renewable energy (solar photovoltaic and wind) based on simulations under multiple emission scenarios. Our results show that air pollution substantially reduced mitigation potential through concurrent losses in terrestrial carbon sinks and renewable energy. The integrated carbon mitigation potential declines by 1.22 Gt CO 2 a −1 due to air pollution across the Northern Hemisphere, with a pronounced reduction of 0.416 Gt CO 2 a −1 in China. Furthermore, the adverse effects of air pollution on carbon mitigation potential are projected to persist in the future. Our results demonstrate that air quality improvement provides an important climate mitigation co-benefit by enhancing carbon uptake and renewable energy potential, with significant implications for designing strategies to achieve the Sustainable Development Goals.
