Dataset of City-level CO2 emissions in China during 1992-2023

Based on current CO2 emission accounting methods and results, this study employed nighttime lights (NTL) remote sensing data, coupled with the XGBoost model and a multi-task learning model, to develop a data alignment technique for carbon accounting by integrating correction, supplementation, and prediction functionalities. As a result, a dataset of CO2 emissions covering 329 cities (including 4 municipalities and 325 prefecture-level cities) from 1992 to 2023 was compiled.
