The seasonal, weekly, and holiday changes in carbon dioxide emissions in each province were announced for the first time. Add week and holiday information as attribution to this dataset for further analysis of the impact of weekends and holidays on China's carbon dioxide emissions. This fine-grained and timely inventory will contribute to more localized and adaptive management of carbon dioxide emissions during pandemic recovery and ongoing energy transition periods.
