Country-level shares of the GSCC (that is, CSCC/GSCC) versus shares of the 2013 CO2 emissions. The CSCC is the median estimate with growth adjusted discounting (ρ = 2%, μ = 1.5) for SSP2/RCP6.0 and BHM-SR. Points are shaded by CSCC per capita and sized according to country GDP in 2015. Diagonal lines show the ratio of the GSCC share to the emissions share. Ratios greater than 1:1 indicate that a country’s share of the GSCC exceeds its share of global emission. The box in the left panel indicates the bounds of the detail shown in the right panel.
