  • Monthly methane emissions in Chinese mainland provinces from 2013-2022. Scientific data Cui, D., Yang, S., Song, X., Huang, X., Duan, C., Ji, M., Li, Z., Yu, S., Deng, Z., Ke, P., Dou, X., Sun, T., Liu, Z. 2025; 12 (1): 948

    Abstract

    As the world's largest source of methane emissions, accurately measuring and tracking China's emissions across various sectors is essential for global climate change efforts. Methane, a potent greenhouse gas, is emitted from diverse anthropogenic and natural sources, many of which exhibit pronounced temporal variability. In particular, emissions from rice cultivation, energy use, and livestock management show strong seasonal patterns, yet high-frequency and spatially detailed methane emission inventories have been lacking. This study introduces the Monthly Methane Emission Inventory for China's Provinces (MMCP), a comprehensive dataset covering the period from January 2013 to December 2022. The dataset includes emissions data from eight key sectors: coal mining, oil and gas systems, energy combustion, rice cultivation, livestock, solid waste, wastewater, and wetlands. By offering sector-specific and temporally resolved emission estimates, MMCP serves as a valuable resource for scientific research, policy evaluation, and emission mitigation planning. This inventory facilitates improved understanding of emission trends and supports more accurate modeling of atmospheric methane concentrations and climate feedbacks.

  • China's municipal wastewater policies enhanced seafood safety and offset health risks from atmospheric mercury emissions in the past four decades. Nature food Cai, X., Yang, M., Liu, M., Chen, Y., Yu, C., Zhang, H., Zhang, Q., Ma, S., Dou, X., Meng, J., Wang, X. 2025

    Abstract

    The neurotoxin methylmercury in seafood threatens food safety worldwide. China has implemented stringent wastewater policies, established numerous treatment facilities and enforced rigorous water quality standards to address pollution in its waterways. However, the impact of these policies on seafood safety and methylmercury exposure remains unknown. Here we developed a process-based model showing that, although mercury reductions from municipal wastewater policies accounted for only 9% of atmospheric mercury emissions during 1980-2022, these measures unexpectedly prevented 102,000 - 6,600 + 11,000 mercury-related deaths and counteracted nearly two thirds of potential deaths from those emissions. Furthermore, these policies ensured that 146 - 9 + 8 megatonnes of freshwater seafood met the World Health Organization and China's mercury-safety standards, preventing US $ 498 - 29 + 32 billion in economic losses. Finally, we explore how China, as the primary global seafood producer and exporter, could develop municipal wastewater policies at the regional level to reduce aquatic pollutants and unlock the health benefits of seafood consumption.
