- Biodiversity > GEF benefits index for biodiversity > 0 = no biodiversity potential to 100 = maximum: GEF benefits index for biodiversity (0 = no biodiversity potential to 100 = maximum). GEF benefits index for biodiversity is a composite index of relative biodiversity potential for each country based on the species represented in each country, their threat status, and the diversity of habitat types in each country. The index has been normalized so that values run from 0 (no biodiversity potential) to 100 (maximum biodiversity potential).
- Biodiversity > Mammal species, threatened: Mammal species, threatened. Mammal species are mammals excluding whales and porpoises. Threatened species are the number of species classified by the IUCN as endangered, vulnerable, rare, indeterminate, out of danger, or insufficiently known.

- Emissions > CO2 emissions > Kt: Carbon dioxide emissions are those stemming from the burning of fossil fuels and the manufacture of cement. They include carbon dioxide produced during consumption of solid, liquid, and gas fuels and gas flaring."
- Emissions > CO2 emissions > Metric tons per capita: Carbon dioxide emissions are those stemming from the burning of fossil fuels and the manufacture of cement. They include carbon dioxide produced during consumption of solid, liquid, and gas fuels and gas flaring."
