Synergistic control of carbon emissions and pollutant concentrations can efficiently tackle climate change and air pollution. The synergistic performance and co-benefits yielded by controlling these factors are urgent and critical issues in China. Accordingly, a comprehensive indicator for assessing synergistic performance is pioneered, and co-benefits of mitigating CO and PM in Chinese cities are evaluated. Chinese synergistic performance is dominated by CO variations. In 2015-2020, multiple northeastern, central, southern, and eastern cities exhibited synergistic effects by greatly reducing CO emissions. The synergistic performance thereafter leads to co-benefits through environmental and economic feedbacks. The CO and PM controls in Northeast Chinese cities feature the most profound co-benefits of approximate 4800 CNY per capita, with each contributing 72 % and 28 %, respectively, to this total. The findings provide intercity synergistic performance and scientific support for policymaking.
碳排放与污染物浓度的协同控制能够有效应对气候变化和空气污染。在中国，控制这些因素所产生的协同绩效和共同效益是亟待解决的关键问题。据此，本文率先提出了一个评估协同绩效的综合指标，并对中国城市中减排一氧化碳（CO）和颗粒物（PM）的共同效益进行了评估。中国的协同绩效主要受CO变化的影响。在2015年至2020年期间，多个东北、中部、南部和东部城市通过大幅减少CO排放展现出协同效应。此后，协同绩效通过环境和经济反馈产生共同效益。中国东北城市的CO和PM控制具有最显著的共同效益，人均约4800元人民币，其中CO和PM分别占总效益的72%和28%。这些研究结果为政策制定提供了城市间协同绩效及科学依据。
