Brazil is being the top country by GEF benefits index for biodiversity in the world. As of 2008, GEF benefits index for biodiversity in Brazil was 100 0 = no biodiversity potential; 100 = maximum. The top 5 countries also includes the United States of America, Australia, Indonesia, and Mexico.
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).
