Extended Data Fig. 5: Carbon mitigation costs for four levels of national mitigation efforts under alternative formations of policy heterogeneity.

Here we show the carbon mitigation cost in 2050 as a fraction of projected 2050 GDP, by three groups of states (low, medium and high-supporting states). ‘Uni’ stands for the uniform approach. Het, Het (Gov), Het (LN), Het (+range), Het (3 zero), Het (5 zero) and Het (AP) represent different heterogeneous approaches with detailed description in the Sensitivity Analysis section and Supplementary Methods. The inserted figure shows the contribution by low-, medium-, and high-supporting states to national total CO2 emissions in 201650.
