3.1. Data description | |||
Air emissions accounts (AEA) record flows of gaseous and particulate materials emitted into the atmosphere as a result of economic activity. AEA are a subset of environmental-economic accounts. They offer a detailed breakdown for 64 emitting economic activities (NACE), plus households, as defined in the national accounts of EU countries. They are aligned with economic statistics and GDP. These features make them suitable for integrated environmental-economic analyses and modelling – for example of 'carbon footprints' and climate-change modelling scenarios. National Statistical Institutes (NSI) submit AEA to Eurostat through a mandatory annual data collection. The data collection includes an electronic questionnaire and this quality report.
|
|||
3.2. Classification system | |||
The AEA dataset has the following dimensions: 1) Air pollutant: Emissions to air of the following gaseous and particulate substances are collected (greenhouse gases, air pollutants): Carbon dioxide without emissions from biomass (CO2), Carbon dioxide from biomass (Biomass CO2)*, Nitrous oxide (N2O), Methane (CH4), Perfluorocarbons (PFCs), Hydrofluorocarbons (HFCs), Sulphur hexafluoride (SF6) including nitrogen trifluoride (NF3), Nitrogen oxides (NOx), Non-methane volatile organic compounds, (NMVOC), Carbon monoxide (CO), Particulate matter < 10μm (PM10), Particulate matter < 2,5μm (PM2,5), Sulphur dioxide (SO2), Ammonia (NH3) 2) Geopolitical entity: EU Member States, EFTA Countries, Candidate Countries etc. 3) Economic activities: include 64 production activities (classified by NACE rev.2 A*64), and households’ consumption (3 sub-classes). 4) Time: reference year for which air emissions are reported 5) Unit: tonnes and thousand tonnes |
|||
3.3. Coverage - sector | |||
The data refer to national economies as defined in the system of national accounts. Greenhouse gases and air pollutants emitted by resident units representing the national economy are covered. |
|||
3.4. Statistical concepts and definitions | |||
Conceptually AEA belong to the international system of environmental economic accounting (SEEA-Central Framework). Furthermore, AEA is one of several physical modules of Eurostat's programme on European environmental economic accounts. It is covered by Regulation (EU) No.691/2011 on European environmental economic accounts. AEA are closely related to concepts and definitions of national accounts. Most notably, they follow the residence principle, i.e. they record emissions related to resident unit's activities, regardless where those occur geographically. Further methodological guidelines are provided in various publications by Eurostat (see Eurostat website > Environment > Methodology, heading: 'Air emissions accounts'). |
|||
3.5. Statistical unit | |||
Data refer to emissions by resident economic units in the sense of SEEA CF 2012 and National Accounts (ESA), including households. |
|||
3.6. 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. |
|||
3.7. 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). |
|||
3.8. Coverage - Time | |||
2008-2021 |
|||
3.9. Base period | |||
Not applicable because AEA are not reported as indices. |
|
|||
The unit of measure is tonnes or thousand tonnes. F-gases (HFC, PFC, SF6 and NF3) are reported in tonnes of CO2 equivalents. SOX are reported in tonnes of SO2 equivalents, and NOX are reported in tonnes of NO2 equivalents. |
|
|||
The data refer to calendar years. |
