Environment > Emissions Stats: compare key data on Portugal & United States
Definitions
- Agricultural methane emissions > % of total: Agricultural methane emissions are emissions from animals, animal waste, rice production, agricultural waste burning (nonenergy, on-site), and savannah burning."
- Agricultural nitrous oxide emissions > % of total: Agricultural nitrous oxide emissions are emissions produced through fertilizer use (synthetic and animal manure), animal waste management, agricultural waste burning (nonenergy, on-site), and savannah burning."
- CO2 emissions > Kg per 2000 US$ of GDP: 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 > Kg per 2005 PPP $ of GDP: 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 > Kg per PPP $ of GDP: 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: 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 > 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."
- CO2 intensity > Kg per kg of oil equivalent energy use: Carbon dioxide emissions from solid fuel consumption refer mainly to emissions from use of coal as an energy source.
- Industrial methane emissions > % of total: Industrial methane emissions are emissions from the handling, transmission, and combustion of fossil fuels and biofuels."
- Methane emissions > Kt of CO2 equivalent: Methane emissions are those stemming from human activities such as agriculture and from industrial methane production.
- Nitrous oxide emissions > Thousand metric tons of CO2 equivalent: Nitrous oxide emissions are emissions from agricultural biomass burning, industrial activities, and livestock management."
- Other greenhouse gas emissions > HFC > PFC and SF6 > Thousand metric tons of CO2 equivalent: Other greenhouse gas emissions are by-product emissions of hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride."
- PM10 > Country level > Micrograms per cubic meter: Particulate matter concentrations refer to fine suspended particulates less than 10 microns in diameter (PM10) that are capable of penetrating deep into the respiratory tract and causing significant health damage. Data for countries and aggregates for regions and income groups are urban-population weighted PM10 levels in residential areas of cities with more than 100,000 residents. The estimates represent the average annual exposure level of the average urban resident to outdoor particulate matter. The state of a country's technology and pollution controls is an important determinant of particulate matter concentrations."
