03.1. Data description

Emissions to air present a process of emitted pollutants into the air from the economic system, generated during the production or consumption processes. Emissions are released into an atmosphere which is part of the system of environmental protection.

Air emission account record the flows of gaseous and particulate materials from the national economy into the air, incurred as a result of the economic activities of the national economy, i.e. industry and private households.

Data for the calculation of the air emissions have been established in accordance with the Convention on Long – range Transboundary Air Pollution (CLRTAP) and United Nations Framework Convention on Climate Change (UNFCCC).

The air emissions account is based on data from administrative sources (National Emissions Inventory (UNFCCC / CRLTAP) and relevant ministries) and statistical sources (agriculture, industry, energy, employment).

03.2. Classification system

Data are collected on the emissions to air:

  1.  Air pollutants:
  • Nitrogen oxides (NOx),
  • Non-methane volatile organic compounds, (NMVOC),
  • Sulphur dioxide (SO2), 
  • Ammonia (NH3),
  • Carbon monoxide (CO),
  • Particulate matter < 10μm (PM10),
  • Particulate matter < 2,5μm (PM2,5), and
  1. Greenhouse gases:
  • Carbon dioxide (CO2),
  • Carbon dioxide from biomass (Biomass CO2),
  • Nitroux oxide (N2O),
  • Methane (CH4),
  • Perfluorocarbons (PFCs),
  • Hydrofluorocarbons (HFCs),
  • Sulphur hexafluoride (SF6),
  • nitrogen trifluoride (NF3).


Data are collected and published broken down by NACE classification of economic activities. The aggregation level used is A*64 (i.e. 64 divisions), fully compatible with ESA supply, use and input-output tables. Emissions from households are also included.


03.3. Coverage - sector

Greenhouse gases and air pollutants emitted by the entire national economy are covered.

03.4. Statistical concepts and definitions

Air Emissions Accounts record the flows of residual gaseous and particulate materials emitted by resident units and flowing into the atmosphere.

Residual gaseous and particulate materials are the physical flows of gaseous or particulate materials (‘air emissions’).

Air emissions accounts record emissions arising from the activities of all resident units (=economic activities), regardless of where these emissions actually occur geographically. Air emissions accounts have the same system boundaries as ESA and are also based on the residence principle.

Natural flows of residual gaseous and particulate materials are excluded e.g. volcanos, forest fires. Also excluded are air emissions arising from land use, land use changes and forestry as well as any indirect emissions.

Air emission account is covered by Regulation (EU) 691/2011 of the European Parliament and the Council of 6 July 2011, and methodologically harmonized with Compilation Guide (2015) for Eurostat`s Air Emissions Accounts (AEA) , and is based on the principles and definitions of the European System of Accounts (European System of Accounts 2010 – ESA 2010).

03.5. Statistical unit

Data refer to emissions by resident economic units in the sense of SEEA CF 2012 and National Accounts (ESA), including households.

03.6. Statistical population

The national economy is as defined in SEEA CF 2012 and National Accounts (ESA), i.e. all economic activities undertaken by resident units.

03.7. Reference area

The reference area is the economic territory as defined in SEEA CF 2012 and National Accounts (ESA). A unit is said to be a resident unit of a country when it has a centre of economic interest in the economic territory of that country, that is, when it engages for an extended period (1 year or more) in economic activities in that territory.

By following this residence principle, the Air Emission Accounts record emissions from resident units' activities, regardless where they occur. This is the main conceptual difference to emission inventories for greenhouse gases (UNFCCC) and air pollutants (CLRTAP).

03.8. Coverage - Time

Data are annual. In NACE rev. 2 breakdown complete time series are available since 2008 for air emission pollutants and from 2010 for greenhouse gases emission.
