Figure 13.3 | Sub-national GHG mitigation commitments: Total population by IPCC region. Population of sub-national actors (cities and regions) recording climate action commitments as captured in the ClimActor dataset. Population calculation considers overlap between City and Regions by only accounting for population once for Cities and Regions that are nested jurisdictions.
