Definitions

  • Adjusted net national income > Constant 2000 US$: Adjusted net national income (constant 2000 US$). Adjusted net national income is GNI minus consumption of fixed capital and natural resources depletion.
  • Adjusted net national income > Constant 2000 US$ per capita: Adjusted net national income (constant 2000 US$). Adjusted net national income is GNI minus consumption of fixed capital and natural resources depletion. Figures expressed per capita for the same year.
  • Biodiversity > Bird species, threatened: Bird species, threatened. Birds are listed for countries included within their breeding or wintering ranges. Threatened species are the number of species classified by the IUCN as endangered, vulnerable, rare, indeterminate, out of danger, or insufficiently known.
  • CO2 Emissions per 1000: CO2: Total Emissions (excluding land-use) Units: thousand metric tonnes of carbon dioxide. Figures expressed per thousand population for the same year.
  • 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.
  • CO2 emissions > Kt per 1000: 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. Figures expressed per thousand population for the same year.
  • Climate change > CO2 emissions > Kt: 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.
  • Climate change > CO2 emissions > Kt per 1000: 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. Figures expressed per thousand population for the same year.
  • Climate change > CO2 emissions > Metric tons per capita: 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.
  • Current issues: This entry lists the most pressing and important environmental problems. The following terms and abbreviations are used throughout the entry:
  • 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."
  • Forest area > Sq. km > Per capita: Forest area is land under natural or planted stands of trees, whether productive or not. Per capita figures expressed per 1,000 population.
  • Proportion of land area under protection: Terrestrial areas protected to total surface area, percentage.
  • Water > Drinking water > Population with improved drinking water sources > Urban and rural: Proportion of the population using improved drinking water sources, total.
  • Water pollution > Organic water pollutant > BOD emissions > Kg per day: 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."
