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.
Climate change > CO2 emissions from electricity and heat production, total > Million metric tons: CO2 emissions from electricity and heat production, total (million metric tons). CO2 emissions from electricity and heat production is the sum of three IEA categories of CO2 emissions: (1) Main Activity Producer Electricity and Heat which contains the sum of emissions from main activity producer electricity generation, combined heat and power generation and heat plants. Main activity producers (formerly known as public utilities) are defined as those undertakings whose primary activity is to supply the public. They may be publicly or privately owned. This corresponds to IPCC Source/Sink Category 1 A 1 a. For the CO2 emissions from fuel combustion (summary) file, emissions from own on-site use of fuel in power plants (EPOWERPLT) are also included. (2) Unallocated Autoproducers which contains the emissions from the generation of electricity and/or heat by autoproducers. Autoproducers are defined as undertakings that generate electricity and/or heat, wholly or partly for their own use as an activity which supports their primary activity. They may be privately or publicly owned. In the 1996 IPCC Guidelines, these emissions would normally be distributed between industry, transport and "other" sectors. (3) Other Energy Industries contains emissions from fuel combusted in petroleum refineries, for the manufacture of solid fuels, coal mining, oil and gas extraction and other energy-producing industries. This corresponds to the IPCC Source/Sink Categories 1 A 1 b and 1 A 1 c. According to the 1996 IPCC Guidelines, emissions from coke inputs to blast furnaces can either be counted here or in the Industrial Processes source/sink category. Within detailed sectoral calculations, certain non-energy processes can be distinguished. In the reduction of iron in a blast furnace through the combustion of coke, the primary purpose of the coke oxidation is to produce pig iron and the emissions can be considered as an industrial process. Care must be taken not to double count these emissions in both Energy and Industrial Processes. In the IEA estimations, these emissions have been included in this category.

Climate change > CO2 emissions from electricity and heat production, total > % of total fuel combustion: CO2 emissions from electricity and heat production, total (% of total fuel combustion). CO2 emissions from electricity and heat production is the sum of three IEA categories of CO2 emissions: (1) Main Activity Producer Electricity and Heat which contains the sum of emissions from main activity producer electricity generation, combined heat and power generation and heat plants. Main activity producers (formerly known as public utilities) are defined as those undertakings whose primary activity is to supply the public. They may be publicly or privately owned. This corresponds to IPCC Source/Sink Category 1 A 1 a. For the CO2 emissions from fuel combustion (summary) file, emissions from own on-site use of fuel in power plants (EPOWERPLT) are also included. (2) Unallocated Autoproducers which contains the emissions from the generation of electricity and/or heat by autoproducers. Autoproducers are defined as undertakings that generate electricity and/or heat, wholly or partly for their own use as an activity which supports their primary activity. They may be privately or publicly owned. In the 1996 IPCC Guidelines, these emissions would normally be distributed between industry, transport and "other" sectors. (3) Other Energy Industries contains emissions from fuel combusted in petroleum refineries, for the manufacture of solid fuels, coal mining, oil and gas extraction and other energy-producing industries. This corresponds to the IPCC Source/Sink Categories 1 A 1 b and 1 A 1 c. According to the 1996 IPCC Guidelines, emissions from coke inputs to blast furnaces can either be counted here or in the Industrial Processes source/sink category. Within detailed sectoral calculations, certain non-energy processes can be distinguished. In the reduction of iron in a blast furnace through the combustion of coke, the primary purpose of the coke oxidation is to produce pig iron and the emissions can be considered as an industrial process. Care must be taken not to double count these emissions in both Energy and Industrial Processes. In the IEA estimations, these emissions have been included in this category.

These numbers do not represent total HFCs emissions over 100 years, but rather the total amount of CO2 that would have to be emitted to have the same global warming potential (GWP) as the total amount of HFCs emitted over 100 years. A 100 year timeframe is used since HFCs have a shorter atmospheric lifetime than CO2. The GWP of a greenhouse gas is useful in determining a country's overall impact on climate change. Figures expressed per million people for the same year.
Water pollution > Chemical industry > % of total BOD emissions: Industry shares of emissions of organic water pollutants refer to emissions from manufacturing activities as defined by two-digit divisions of the International Standard Industrial Classification (ISIC), revision 2: chemicals (35). 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.
Adjusted savings > Adjusted savings > Energy depletion > % of GNI: Energy depletion is equal to the product of unit resource rents and the physical quantities of energy extracted. It covers crude oil, natural gas, and coal."

This is a standard water-treatment test for the presence of organic pollutants."
Freshwater > Annual freshwater withdrawals > Agriculture > % of total freshwater withdrawal: Annual freshwater withdrawals refer to total water withdrawals, not counting evaporation losses from storage basins. Withdrawals also include water from desalination plants in countries where they are a significant source. Withdrawals can exceed 100 percent of total renewable resources where extraction from nonrenewable aquifers or desalination plants is considerable or where there is significant water reuse. Withdrawals for agriculture are total withdrawals for irrigation and livestock production. Data are for the most recent year available for 1987-2002."
Climate change > GHG net emissions/removals by LUCF > Mt of CO2 equivalent per million: GHG net emissions/removals by LUCF (Mt of CO2 equivalent). GHG net emissions/removals by LUCF refers to changes in atmospheric levels of all greenhouse gases attributable to forest and land-use change activities, including but not limited to (1) emissions and removals of CO2 from decreases or increases in biomass stocks due to forest management, logging, fuelwood collection, etc.; (2) conversion of existing forests and natural grasslands to other land uses; (3) removal of CO2 from the abandonment of formerly managed lands (e.g. croplands and pastures); and (4) emissions and removals of CO2 in soil associated with land-use change and management. For Annex-I countries under the UNFCCC, these data are drawn from the annual GHG inventories submitted to the UNFCCC by each country; for non-Annex-I countries, data are drawn from the most recently submitted National Communication where available. Because of differences in reporting years and methodologies, these data are not generally considered comparable across countries. Data are in million metric tons. Figures expressed per million population for the same year.
Adjusted savings > Adjusted savings > Net national savings > % of GNI: Net national savings are equal to gross national savings less the value of consumption of fixed capital.

Emissions > 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."
Climate change > CO2 emissions from other sectors, excluding residential buildings and commercial and public services > % of total fuel combustion: CO2 emissions from other sectors, excluding residential buildings and commercial and public services (% of total fuel combustion). CO2 emissions from other sectors, less residential buildings and commercial and public services, contains the emissions from commercial/institutional activities, residential, agriculture/forestry, fishing and other emissions not specified elsewhere that are included in the IPCC Source/Sink Categories 1 A 4 and 1 A 5. In the 1996 IPCC Guidelines, the category also includes emissions from autoproducers in the commercial/residential/agricultural sectors that generate electricity and/or heat. The IEA data are not collected in a way that allows the energy consumption to be split by specific end-use and therefore, autoproducers are shown as a separate item (Unallocated Autoproducers).
Emissions > 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."
Adjusted savings > Adjusted savings > Net national savings > Current US$: Net national savings are equal to gross national savings less the value of consumption of fixed capital.
Adjusted savings > Adjusted net savings > Excluding particulate emission damage > Current US$: Adjusted net savings are equal to net national savings plus education expenditure and minus energy depletion, mineral depletion, net forest depletion, and carbon dioxide. This series excludes particulate emissions damage."
Pollution > Greenhouse gas emissions > Perfluorcarbons (PFCs) > Emissions (CO2 equivalent) per million people: Carbon dioxide equivalent of perfluorocarbons emissions over 100 years. These numbers do not represent total PFCs emissions, but rather the total amount of CO2 that would have to be emitted to have the same global warming potential (GWP) as the total amount of PFCs emitted over 100 years. A 100 year time scale is used since PFCs have a shorter atmospheric lifetime than CO2. The GWP of a greenhouse gas is useful in determining a country's overall impact on climate change. Figures expressed per million people for the same year.
