CO2: Total Emissions (excluding land-use) Units: thousand metric tonnes of carbon dioxide
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.
Endangered species protection:
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.
Water > Availability:
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)
Water > Freshwater pollution:
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.
continues to reduce greenhouse gas emissions (has met Kyoto Protocol target of a 12.5% reduction from 1990 levels and intends to meet the legally binding target and move toward a domestic goal of a 20% cut in emissions by 2010); by 2005 the government reduced the amount of industrial and commercial waste disposed of in landfill sites to 85% of 1998 levels and recycled or composted at least 25% of household waste, increasing to 33% by 2015
air pollution resulting in acid rain in both the US and Canada; the US is the largest single emitter of carbon dioxide from the burning of fossil fuels; water pollution from runoff of pesticides and fertilizers; limited natural fresh water resources in much of the western part of the country require careful management; desertification
