Direct source Direct sourceThe OECD methodology takes the emission data from the national greenhouse gas inventories submitted under the United Nations Framework Convention on Climate Change (UNFCCC) as a starting point. The emission data in the inventories are allocated to ISIC rev. 4 industries and households using the correspondence table proposed by Eurostat.
When the correspondence table requires the allocation of an inventory item to more than one industry, the OECD opted for using an allocation method based on output data since output closely correlates with emissions. Specifically, the allocation from one inventory to more-than-one industry is made according to the output share of each industry relative to the total output of those industries involved in the split*.
Data refer to total emissions of carbon dioxide (CO2 emissions from energy use and industrial processes), methane (CH4 emissions from solid waste, livestock, mining of hard coal and lignite, rice paddies, agriculture and leaks from natural gas pipelines) and nitrous oxide (N2O emissions) for greenhouse gas (GHG) emissions.

Population & Scope Population & Scope Statistical population Statistical populationThe “Air emission accounts – OECD Estimates” database is organised along 4 dimensions: Country - Pollutant - Year - Activity.
Country Dimension: Japan (JPN) – United States (USA) – Kazakhstan (KAZ) – Russia (RUS) – Ukraine (UKR).
Pollutant Dimension: Greenhouse gas emissions (GHG) – Carbon dioxide emissions (CO2) – Methane emissions (CH4) – Nitrous oxide emissions (N2O).
Year Dimension: From 2007 onwards.
Activity Dimension: This dimension allows breaking down air emissions across industries and households’ activities.
1) Industries: Industries are broken down using the ISIC rev. 4 classification (http://unstats.un.org/unsd/cr/registry/isic-4.asp).
2) Households: Households’ activities are broken down using the COICOP classification (http://unstats.un.org/unsd/cr/registry/regcst.asp?Cl=5).
Other Aspects Other Aspects Other comments Other commentsJapan: "Electricity, gas, steam and air conditioning supply" (D) includes "Electricity, gas, steam and air conditioning supply (D), and Water supply; sewerage, waste management and remediation activities (E)".
Kazakhstan: For 2018 estimates, 2017 production values were used as weights for distribution of emissions because 2018 production figures were not yet available.
