Percent of CITES reporting requirements met Units: Percent of Requirements Met Units: Countries that have not ratified the CITES convention are recorded as having zero percent of their requirements met.
Municipal waste is that which is collected and treated by or for municipalities: household waste and bulky waste as well as comparable waste from small communities or industrial enterprises; and market and garden residue.

Water availability per capita (1961-1990 (avg.)) Units: Thousands Cubic Meters/Person Units: This variable measures internal renewable water (average annual surface runoff and groundwater recharge generated from endogenous precipitation)

Industrial organic pollutants per available freshwater Units: Metric Tons of BOD Emissions per Cubic Km of Water Units: Emissions of organic water pollutants are measured by biochemical oxygen demand, which refers to the amount of oxygen that bacteria in water will consume in breaking down waste. This is a standard water-treatment test for the presence of organic pollutants. The data from the World Bank, which represented BOD emissions (kilograms per day) were normalized by the combination of water availability per capita and water inflow availability per capita from the WaterGap2.1 model. In calculating the ESI, the base-10 logarithm of this variable was used.

Percent of land area having very low anthropogenic impact Units: Percent of Land Area Units: Global grids for population (GPW), land use (USGS AVHRR based classification from EROS data center), VMAP roads, VMAP railways, VMAP coastlines, VMAP major rivers and the stable lights data were all scored for "wildness". The scores were aggregated and normalized.
