Fig. 4From: A city-level comparison of fossil-fuel and industry processes-induced CO2 emissions over the Beijing-Tianjin-Hebei region from eight emission inventoriesTemporal variation in the annual CO2 emission amounts and emissions intensity from CHRED, CEADs, MEIC, NJU, PKU, ODIAC, EDGAR, and FFDAS in the JJJ region. Solid lines denote CO2 emissions, and dashed lines denote emissions intensity. Note that the scales are different across cities to show their variationsBack to article page
