Air emissions accounts
Statistical activity code: 10406
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)
Estonian Classification of Economic Activities (EMTAK 2008) based on NACE Rev. 2
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
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.

DIRECTLY APPLICABLE LEGAL ACTS
Regulation (EU) No 691/2011 of the European Parliament and of the Council of 6 July 2011 on European environmental economic accounts
Regulation (EU) No 538/2014 of the European Parliament and of the Council of 16 April 2014 amending Regulation (EU) No 691/2011 on European environmental economic accounts (Text with EEA relevance)
OTHER LEGAL ACTS
The dissemination of data collected for the purpose of producing official statistics is guided by the requirements provided for in § 32, § 34, § 35, § 38 of the Official Statistics Act.
The treatment of confidential data is regulated by the Procedure for Protection of Data Collected and Processed by Statistics Estonia (in Estonian). See more details on the website of Statistics Estonia in the section Õigusaktid.
Notifications about the dissemination of statistics are published in the release calendar, which is available on the website. Every year on 1 October, the release times of the statistical database, news releases, main indicators by IMF SDDS and publications for the following year are announced in the release calendar (in the case of publications – the release month).
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.
Data are published under the subject area “Environment / Environmental accounts” in the statistical database at http://pub.stat.ee.
The dissemination of data collected for the purpose of producing official statistics is guided by the requirements provided for in § 33, § 34, § 35, § 36, § 38 of the Access to microdata and anonymisation of microdata are regulated by Statistics Estonia’s procedure for dissemination of confidential data for scientific purposes.

The quality report will be prepared in 2020.
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.
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.

Users’ suggestions and information about taking these into account are available on the website of Statistics Estonia at http://www.stat.ee/statistikatood.
Since 1996, Statistics Estonia has conducted reputation and user satisfaction surveys. All results are available on the website of Statistics Estonia in the section User surveys.
Air emissions accounts are in compliance with the rules of national accounts and are thus complete.
The data revision policy and notification of corrections are described in the section Principles of dissemination of official statistics of the website of Statistics Estonia.
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.

DATA FROM OTHER STATISTICAL ACTIVITIES
Data from statistical activities 20206 “Energy consumption and production (annual)”, 20300 “Financial statistics of enterprises (annual)”, 20902 “Statistics of economic units” and 21408 “Supply and use tables” are used.
Data from the Estonian Environment Agency, the Ministry of the Environment and the Estonian Environmental Research Centre are received via e-mail. Data from the Estonian Road Administration are received via an FTP-server.
Arithmetic and qualitative controls are used in the validation process, including comparison with other data.
New variables are calculated by applying arithmetic conversion to already existing variables.
Microdata are aggregated to the level necessary for analysis.
The collected data are converted into statistical output. This includes calculating additional indicators.
