Definitions
- Carbon dioxide (CO2) > CO2 emissions: Amount of carbon dioxide emissions by select Western countries. Amounts are by thousand metric tons.
- Carbon dioxide (CO2) > CO2 emissions per thousand people: Amount of carbon dioxide emissions by select Western countries. Amounts are by thousand metric tons. . Figures expressed per thousand people for the same year.
- Emissions (CO2 equivalent): Carbon dioxide equivalent of all greenhouse gas emissions not including human-based land use, land use change and forestry. These numbers do not represent total greenhouse gas 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 greenhouse gases emitted. The GWP of a greenhouse gas is useful in determining a country's overall impact on climate change.
- Emissions (CO2 equivalent) per thousand people: Carbon dioxide equivalent of all greenhouse gas emissions not including human-based land use, land use change and forestry. These numbers do not represent total greenhouse gas 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 greenhouse gases emitted. The GWP of a greenhouse gas is useful in determining a country's overall impact on climate change. Figures expressed per thousand people for the same year.
- Hydrofluorocarbons (HFCs) > Emissions (CO2 equivalent): Carbon dioxide equivalent of Hydrofluorocarbons (HFCs) emissions over a 100 year period. 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.
- Hydrofluorocarbons (HFCs) > Emissions (CO2 equivalent) per million people: Carbon dioxide equivalent of Hydrofluorocarbons (HFCs) emissions over a 100 year period. 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.
- Methane (CH4) > Emissions (CO2 equivalent): Carbon dioxide equivalent of methane emissions not including human-based land use, land use change and forestry. These numbers do not represent total methane emissions, but rather the total amount of CO2 that would have to be emitted to have the same global warming potential (GWP) as the amount of methane emitted, which is 21 times more CO2. The GWP of a greenhouse gas is useful in determining a country's overall impact on climate change.
- Methane (CH4) > Emissions (CO2 equivalent) per thousand people: Carbon dioxide equivalent of methane emissions not including human-based land use, land use change and forestry. These numbers do not represent total methane emissions, but rather the total amount of CO2 that would have to be emitted to have the same global warming potential (GWP) as the amount of methane emitted, which is 21 times more CO2. The GWP of a greenhouse gas is useful in determining a country's overall impact on climate change. Figures expressed per thousand people for the same year.
- Nitrous oxide (N2O) > Emissions (CO2 equivalent): Carbon dioxide equivalent of nitrous oxide emissions not including human-based land use, land use change and forestry. These numbers do not represent total NO2 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 NO2 emitted, which is 310 times more CO2. The GWP of a greenhouse gas is useful in determining a country's overall impact on climate change.
- Nitrous oxide (N2O) > Emissions (CO2 equivalent) per million people: Carbon dioxide equivalent of nitrous oxide emissions not including human-based land use, land use change and forestry. These numbers do not represent total NO2 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 NO2 emitted, which is 310 times more 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.
- Perfluorcarbons (PFCs) > Emissions (CO2 equivalent): 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.
- 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.
- Sulphur hexafluoride (SF6) > Emissions (CO2 equivalent): Carbon dioxide equivalent of sulphur hexafluoride emissions over 100 years. These numbers do not represent total SF6 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 SF6 emitted over 100 years. A 100 year time scale is used since SF6 has a shorter atmospheric lifetime than CO2. The GWP of a greenhouse gas is useful in determining a country's overall impact on climate change.
- Sulphur hexafluoride (SF6) > Emissions (CO2 equivalent) per million people: Carbon dioxide equivalent of sulphur hexafluoride emissions over 100 years. These numbers do not represent total SF6 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 SF6 emitted over 100 years. A 100 year time scale is used since SF6 has 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.
