Nitrous oxide (N2O) currently lacks high-resolution urban data, hindering targeted regional mitigation. To address this, we developed a bottom-up N2O emission inventory for 339 Chinese cities from 2010 to 2024. We find national emissions substantially exceed international estimates due to uncounted industrial sources...
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....

City-scale, source-resolved methane (CH4) inventories are needed in China because prefecture-level cities differ in energy systems, agricultural activities, and waste management. These differences lead to divergent dominant sources and mitigation needs. Yet city-level CH4 inventories across the energy, agriculture, and...

China is the world's largest source of methane (CH4) emissions and has signalled its intention to incorporate methane into its climate commitments. Designing effective methane-mitigation strategies requires robust estimates of up-to-date emissions, particularly when the pronounced spatial heterogeneity and temporal var...
