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 | |||
2000-2021 |
|||
3.9. Base period | |||

18.1. Source data | |||
The main data source Inventory reports to UNFCC and CLRTP. Acitivy data about energy consumption are collected with survey “2-EK, Survey on stocks, production, receipts and consumption of energy resources”. It is a sample survey, and all groups of NACE are included, starting from 01-93. Data on energy consumption including for transport of different energy products are obtained from this survey. Other data are allocated to NACE based on information in inventory reports and underlying activity data. Emissions from fuel combustion activities were allocated to industries using detailed energy statistics. As in first place emissions were calculated using energy statistics as activity data provided by CSB. Fugitive emissions were allocated based on information given in Inventory reports. All emissions from Agriculture sector were allocated to NACE 01. Emissions from the Waste sector were allocated based on information on waste and wastewater. Most of emissions from Industrial processes and product use were allocated directly to respective NACE. As emissions from cement production to NACE 23, asphalt roofing to NACE 43 etc. Part of emissions were using economic data (turnover)-paint application and degreasing and dry cleaning; emissions from Chemical products, manufacture and processing arises from on production of pharmaceutical formulations and perfumery products and were allocated to NACE 20. As described in inventory report emissions from N2O used in anesthesia activities are estimated taking into account amount of N2O actually used in medicine sector, so these emissions were allocated to NACE 86. CO2 emissions from non-energy products from fuels use was allocated to NACE 49, NACE 16 and NACE 31-32 based on information in inventory report and activity data.

18.5. Data compilation | |||
For data compilation Inventory first method is used. Emissions from fuel combustion activities were allocated to industries using detailed energy statistics. As in first place emissions were calculated using energy statistics as activity data provided by CSB. Fugitive emissions were allocated based on information given in Inventory reports. All emissions from Agriculture sector were allocated to NACE 01. Emissions from the Waste sector were allocated based on information on waste and wastewater. Most of emissions from Industrial processes and product use were allocated directly to respective NACE. As emissions from cement production to NACE 23, asphalt roofing to NACE 43 etc. Part of emissions were using economic data (turnover)-paint application and degreasing and dry cleaning; emissions from Chemical products, manufacture and processing arises from on production of pharmaceutical formulations and perfumery products and were allocated to NACE 20. As described in inventory report emissions from N2O used in anesthesia activities are estimated taking into account amount of N2O actually used in medicine sector, so these emissions were allocated to NACE 86. CO2 emissions from non-energy products from fuels use was allocated to NACE 49, NACE 16 and NACE 31-32 based on information in inventory report and activity data. |
|||
18.5.1. Imputation - rate | |||
Not applicable. |
|||
18.5.2. Method used to allocate emissions to economic activities | |||
Main data source for energy data is “2-EK, Survey on stocks, production, receipts and consumption of energy resources”. It is sample survey, and all groups of NACE are included, starting from 01-93. Data on energy consumption including for transport of different energy products are obtained from this survey. Other data are allocated to NACE based on information in inventory reports and underlying activity data. |
|||
18.5.3. Method used to determine and distribute road transport emissions | |||
Main data source for fuel consumption is “2-EK, Survey on stocks, production, receipts and consumption of energy resources”. It is sample survey (~6000 respondents), and all groups of Nace are included, starting from 01-96. Data on energy consumption for transport of different energy products - gasoline, diesel biodiesel and LPG are obtained from this survey. Survey contains information on type of vehicle for which fuel are used - passenger cars, heavy duty trucks, buses.
Households fuel consumption are estimated using information of number of different types of vehicles owned by private persons.
Data on use of energy for road transport are distributed between industries and households using information from GHG inventories about fuel use (gasoline, diesel, LPG and biodiesel) for each vehicle type - Passenger cars, Buses, Heavy duty-vehicles (HDV), Light duty-vehicles (LDV) and Mopeds & Motorcycles by applying share from Survey “2-EK, Survey on stocks, production, receipts and consumption of energy resources”. Fuel use for Mopeds & Motorcycles are all allocated to Households.
Air emissions from road transport then are distributed between industries and households using estimated fuel use in industries and households.
|
|||
18.5.4. Adjustments for residence principle | |||
Energy use of diesel and gasoline for heavy-duty vehicles and emissions from heavy-duty vehicles by resident and non-resident units are calculated using formulas from the Manual for air emission accounts. Statistics on goods/freight transport are used for this purpose. Residence principle were applied only to fuels used for heavy-duty trucks and emissions from heavy-duty trucks and were allocated to Nace 49.
According to energy statistics, residents operate about 60% of international flights from Latvia. Same amount of fuel is needed for return flights, so share of emissions has to be doubled. Energy use by residents abroad and energy use by non-residents for international aviation were calculated using data from surveys “2-bunkering; Survey on oil delivery to ships and aircrafts” and “2-EK Report on purchase and use of energy resources". From survey “2-EK”data we gather data on total amounts of fuel used for aviation and amounts of fuel bought and used abroad. Combining data from both surveys we estimated also amounts of fuel purchased by non-residents for international air transportation. Based on this share the appropriate amounts of emissions from international aviation have been added to NACE 51.
Emissions from International maritime navigation was estimated that about 2% of emissions “belong” to ships operating under Latvian flag, those amounts were added to NACE 50
