Fig. 2: Years of peak carbon emissions and the carbon intensity in both peak years and 2030 for all nine scenarios.
From: Air quality and health co-benefits of China’s carbon dioxide emissions peaking before 2030
The size of the circles represents the total carbon emissions, and their centers correspond to the year of peak carbon and the value of carbon intensity in that year. Note that the model results of peak years from GCAM here are at 10-year intervals. REF, RCP2.6, and RCP1.9 are marked in pink, light blue and blue, respectively. The two dashed lines represent China’s NDC targets of peak year of 2030 and carbon intensity by 2030 (i.e., 0.47t-CO2/1000 USD). The carbon intensity in 2030 for the 7 scenarios peaking earlier or later than that year are marked by triangles.
