SOURCES: Protected Areas under IUCN management categories I - VI (1992-2003); Carbon economic efficiency (CO2 emissions per dollar GDP)
Units: Metric Tons/US Dollar GDP; CFC consumption
Units: Ozone Depletion Potential (ODP) Tons (Metric Tons x ODP)
Units: The indicator was obtained by multiplying the Total CFCs emissions (metric tons per ozone depletion potential) with the Per capita CFCs emissions (obtained by dividing the total CFCs emissions by the population in 1997). In calculating the ESI, the base-10 logarithm of this variable was used.; CO2: Total Emissions (excluding land-use) Units: thousand metric tonnes of carbon dioxide; Ecological footprint per capita
Units: Hectares per Person; 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.; Compliance with environmental agreements (WEF survey)
Units: Survey Responses Ranging from 1 (Strongly Disagree) to 7
Units: Response to the statement: "Compliance with international environmental agreements is a high priority.; Known breeding bird mammal species (1992-2002).; Known mammal species (1992-2002).; Total marine fish catch
Units: Metric Tons; NOx emissions per populated land area
Units: 1000 Metric Tons/Sq. Km. of Populated Land Area
Units: We obtained the total emissions for each country by summarizing emissions data, originally available as a grid map with 1 degree x 1 degree cells. Air pollution is generally greatest in densely populated areas. To take this into account, we used the Gridded Population of the World dataset available from CIESIN and calculated the total land area in each country inhabited with a population density of greater than 5 persons per sq. km. We then used this land area as a denominator for the emissions data.; Environmentally protected area (1997); SO2 emissions per populated land area
Units: 1000 Metric Tons/Sq. Km. of Populated Land Area
Units: We obtained the total emissions for each country by summarizing emissions data, originally available as a grid map with 1 degree x 1 degree cells. Air pollution is generally greatest in densely populated areas. To take this into account, we used the Gridded Population of the World dataset available from CIESIN and calculated the total land area in each country inhabited with a population density of greater than 5 persons per sq. km. We then used this land area as a denominator for the emissions data.; Number of Threatened Species (1990-99); Number of threatened mammal species (1997); 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.; Phosphorus concentration
Units: Milligrams/Liter
Units: The country values represent averages of the station-level values for the three year time period 1994-96, except where data were only available for an earlier time period (1988-1993). The number of stations per country varies depending on country size; number of bodies of water; and level of participation in the GEMS monitoring system. The data from "The Wellbeing of Nations" included a smaller subset of stations representing outfalls of major watersheds. An analysis of a sample of countries with numerous stations found that the data for stations in the subset is broadly comparable to the data for all GEMS stations in those countries.; Wetlands of international importance 2002; 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.
