This study updates the carbon emission data to 2024 and expands the spatial coverage from the original 48 high-emission cities to 334 prefecture-level and above cities across China. The goal is to provide more cities with near-real-time carbon emission information to support the formulation and adjustment of their short-term climate and energy policies. The CMCC dataset provides daily CO₂ emission estimates from 2019 to 2024, disaggregated into five key sectors: power generation, residential, industry, ground transportation, and aviation. As a near-real-time dataset, CMCC substantially improves both the temporal resolution and the update frequency of China's urban carbon emission inventories, covering 344 prefecture-level and above cities in mainland China (excluding Hong Kong, Macao, and Taiwan). The total annual uncertainty of the CMCC dataset is estimated to be 9.3%, based on comparisons with widely used inventories such as CM-China, MEIC, and CHRED.

本研究将碳排放数据更新至2024年，并将空间覆盖范围从最初的48个高排放城市拓展至中国334个地级及以上城市。其研究目标是为更多城市提供近实时碳排放信息，以支撑其短期气候与能源政策的制定与调整。CMCC数据集（CMCC）提供了2019年至2024年的每日二氧化碳排放估算值，并拆解为五大核心领域：发电、居民生活、工业、地面交通以及航空运输。作为一款近实时数据集，CMCC大幅提升了中国城市碳排放清单的时间分辨率与更新频率，覆盖中国大陆（不含香港、澳门、台湾地区）344个地级及以上城市。经与CM-China、MEIC、CHRED等广泛使用的碳排放清单比对，CMCC数据集的年度总不确定性估算值为9.3%。
