  1. “Perfomance” is measured by the average outcome of the SDG metric (see Methods section) over the 5 SSP runs
  2. Sectoral decomposition of selected SDG-balanced mitigation pathways by temperature target, and performance over 5 SDG indicators calculated both by multiplying mitigation with MSVs, and by re-calculating the impact from model-driven simulation of SDG-balanced portfolios, for validation purposes.
