3. Statistical presentation
3.1. Data description Main characteristics of the data set described in an easily understandable manner, referring to the data and indicators disseminated.
Air emissions of main greenhouse gases and air pollutants (carbon dioxide, sulphur dioxide, volatile organic compounds, nitrogen oxides, nitrous oxide, methane, ammonia, F-gases, sulphur hexafluoride, particulate matter, fine particles) by economic activity (A*64)
3.2. Classification system Arrangement or division of objects into groups based on characteristics which the objects have in common.
Estonian Classification of Economic Activities (EMTAK 2008) based on NACE Rev. 2
3.3. Sector coverage Main economic or other sectors covered by the statistics.
All institutional sectors and economic activities on the 2-digit level of the Estonian Classification of Economic Activities (EMTAK 2008) based on NACE Rev. 2
3.4. Statistical concepts and definitions Statistical characteristics of statistical observations.
Carbon dioxide equivalent – the amount of CO₂ that would have the same global warming potential as the given amount of greenhouse gas.
Carbon monoxide (CO) – a colourless and odourless gas which is a product of incomplete combustion of carbon compounds (fuels). The biggest sources of CO in urban air are vehicles and household heating.
Emission of carbon dioxide – total anthropogenic carbon dioxide (CO₂) emission from the sectors of energy, industrial processes, solvent and other product use, agriculture, land use change and forestry, and waste. Natural emission is not accounted for in this indicator.
Emission of methane – total anthropogenic methane (CH₄) emission from the sectors of energy, industrial processes, solvent and other product use, agriculture, land use change and forestry, and waste (as defined by IPCC). Natural emission is not accounted for in this indicator.
Emission of nitrous oxide — total anthropogenic nitrous oxide (N₂O) emission from the sectors of energy, industrial processes, solvent and other product use, agriculture, land use change and forestry, and waste (as defined by the IPCC). Natural emission is not accounted for in this indicator.
Hydrofluorocarbons (HFC) – total emissions of different hydrofluorocarbons expressed in CO₂ equivalents. HFCs are used in refrigerant and air conditioning systems as well as in other areas, e.g. insulation foams, installation foams and aerosol sprays.
Nitrogen oxides (NOₓ) – NO and NO₂ are included. For reasons of comparability, emissions of these gases are expressed in NO₂ units.
Non-methane volatile organic compounds – volatile organic compounds are the source of photochemical smog. Some volatile organic compounds, such as benzene and 1,3-butadiene, are carcinogenic.
Particulate matter – solid particles and liquid droplets contained in smoke, dust etc.
Perfluorocarbons (PFC) – total emissions of different perfluorocarbons expressed in CO₂ equivalents.
Sulphur dioxide (SO₂) – sulphur dioxide is formed in the combustion of fuels which contain sulphur. In towns and cities, the main sources of SO₂ are boiler houses and vehicles. Sulphur dioxide emissions cause soil and water acidification and smog.
Sulphur hexafluoride (SF6) – a greenhouse gas with an extremely high global warming potential (GWP = 22,200). Sulphur hexafluoride is used in electrical equipment for electrical power transmission and distributions as an arc quenching and insulating gas.
3.5. Statistical unit Entity for which information is sought and for which statistics are ultimately compiled.
3.6. Statistical population The total membership or population or "universe" of a defined class of people, objects or events.
3.7. Reference area The country or geographic area to which the measured statistical phenomenon relates.
Estonia as a whole
3.8. Time coverage The length of time for which data are available.
3.9. Base period The period of time used as the base of an index number, or to which a constant series refers.
Tonne, tonne of CO₂ equivalent

8.2. Release calendar access Access to the release calendar information.
8.3. User access The policy for release of the data to users, the scope of dissemination (e.g. to the public, to selected users), how users are informed that the data are being released, and whether the policy determines the dissemination of statistical data to all users.
All users have been granted equal access to official statistics: dissemination dates of official statistics are announced in advance and no user category (incl. Eurostat, state authorities and mass media) is provided access to official statistics before other users. Official statistics are first published in the statistical database. If there is also a news release, it is published simultaneously with data in the statistical database. Official statistics are available on the website at 8:00 a.m. on the date announced in the release calendar.

11.1. Quality assurance All systematic activities implemented that can be demonstrated to provide confidence that the processes will fulfil the requirements for the statistical output.
To assure the quality of processes and products, Statistics Estonia applies the EFQM Excellence Model, the European Statistics Code of Practice and the Quality Assurance Framework of the European Statistical System (ESS QAF). Statistics Estonia is also guided by the requirements in § 7. “Principles and quality criteria of producing official statistics” of the Official Statistics Act.
11.2. Quality assessment Overall assessment of data quality, based on standard quality criteria.
Statistics Estonia performs all statistical activities according to an international model (Generic Statistical Business Process Model – GSBPM). According to the GSBPM, the final phase of statistical activities is overall evaluation using information gathered in each phase or sub-process; this information can take many forms, including feedback from users, process metadata, system metrics and suggestions from employees. This information is used to prepare the evaluation report which outlines all the quality problems related to the specific statistical activity and serves as input for improvement actions.

Ministry of the Environment
Users’ suggestions and information about taking these into account are available on the website of Statistics Estonia at https://www.stat.ee/statistikatood.
12.2. User satisfaction Measures to determine user satisfaction.
Since 1996, Statistics Estonia has conducted reputation and user satisfaction surveys.
All results are available on the website at https://www.stat.ee/user-surveys.
12.3. Completeness The extent to which all statistics that are needed are available.
Air emissions accounts are in compliance with the rules of national accounts and are thus complete.
13. Accuracy and reliability Accuracy: closeness of computations or estimates to the exact or true values that the statistics were intended to measure.
13.1. Overall accuracy Assessment of accuracy, linked to a certain data set or domain, which is summarising the various components.
The accuracy of source data is monitored through comparison with other data sources.
Overall accuracy is guaranteed by adherence to methodological recommendations and adoption of best practice.
13.2. Sampling error That part of the difference between a population value and an estimate thereof, derived from a random sample, which is due to the fact that only a subset of the population is enumerated.
13.3. Non-sampling error Error in survey estimates which cannot be attributed to sampling fluctuations.

15.1. Comparability - geographical The extent to which statistics are comparable between geographical areas.
The data are geographically comparable.
15.2. Comparability - over time The extent to which statistics are comparable or reconcilable over time.
The data are comparable over time.
15.3. Coherence - cross domain The extent to which statistics are reconcilable with those obtained through other data sources or statistical domains.
Air emission accounts are coherent with national accounts, material flow accounts, environmental taxes accounts and energy statistics.
15.4. Coherence - internal The extent to which statistics are consistent within a given data set.
The outputs of the statistical activity are coherent.
Cost of statistical activity 36.8 thousand euros (data for 2018)

The published data may be revised if the methodology is modified, errors are discovered, new or better data become available.
The accounts are revised according to revisions:
- in the System of National Accounts;
- in the national report under the UNECE Convention on Long-Range Transboundary Air Pollution (LRTAP);
- in Estonia’s national GHG (greenhouse gas) inventory submission to the UNFCCC (United Nations Framework Convention on Climate Change) secretariat.
