Understanding the spatial-common heterogeneous effects of monetary and meteorological factors on CO2 outpourings from mixes of different locale warming structures with “Coal-to-Gas” progress can add to the improvement of future low-carbon energy systems that are useful and strong. This work downscales city-level CO2 releases to a 3 × 3 km2 gridded level in northern China during 2012 to 2018. By using the Geographically and Temporally Weighted Regression (GTWR) model, evening time light (NTL) data are embraced as a middle person of the level of urbanization, and the Temperature-Humidity-Wind (THW) Index is used as a go-between of meteorological components in the downscaling model. The results show that, for more than 85% of the metropolitan regions, urbanization basically further develops the CO2 spreads of locale warming systems, while the THW Index shows unfavourable outcomes on CO2 releases. Basic spatial and transient heterogeneity exists. The systems with the most significant CO2 outpourings from coalended boilers (lattices with yearly assortment >0.59 Gg CO2 /year) are essentially arranged in nonurban spaces of the two megacities Beijing and Tianjin and moreover in the capital metropolitan spaces of each locale. Urbanization effect sly influences the CO2 spreads of combustible gas ended boilers than of coal-ended boilers and joined hotness and power (CHP). The ordinary improvement speed of CO2 radiations of gas-ended boilers in the metropolitan spaces of the audit districts was around 4.7 events that of nonurban locales. The spatial-transient heterogeneous impacts of urbanization on CO2 releases should in this manner are considered in continuous discussions of clean warming methodologies and climate response systems
