3.1 Data description | |
At national level, data on amount of emitted emissions of air pollutants including emissions of a greenhouse gases (GHG) broken down by economic activities and for households are compiled and published: Air emissions accounts (table zp1002rs). |
|
3.2 Classification system | |
Data in AEA are presented broken down by economic activities in accordance with the statistical classification of economic activities NACE Rev.2. The aggregation level A*64 is applied (it means 64 categories of economic activities), which is fully compatible with the tables in the system of national accounts (input-output tables). Also emissions from households (HH) in the following breakdown are included in AEA: transport, heating/cooling, other. |
|
3.3 Sector coverage | |
|
|
3.4 Statistical concepts and definitions | |
Air emissions accounts (AEA) record the flows of residual gaseous and particulate materials emitted by national economy and households to the atmosphere. Emissions arising from the activities of all resident units, regardless of where these emissions actually occur geographically are included in AEA. AEA have the same system boundaries as the national accounts. Natural flows of residual gaseous and particulate materials are excluded (e.g. volcanoes, forest fires). Also indirect air emissions arising e.g. from land use are excluded. Air emission mean the physical flow of residuals gaseous or particulate materials from the national economy (production or consumption processes) to the atmosphere (as part of the environmental system). |

3.7 Reference area | |
The reference area for AEA is the economic territory as defined in the National Accounts (ESA). By following this residence principle, the AEA record emissions from resident economic units' activities, regardless where they occur. This is the main conceptual difference of the AEA in comparison to emission inventories for greenhouse gases (UNFCCC) and air pollutants (CLRTAP). |

7.1 Confidentiality - policy | |
SOSR has introduced principles and procedures for the protection of confidential data in internal directives and instructions. The directive on the protection of confidential statistical data regulates the method of management and implementation of activities related to ensuring the protection of confidential statistical data in the SOSR. The internal methodological instruction of the SOSR regulates specific methods and parameter values used in the protection of confidential statistical data of individual statistical surveys and data sets. |
|
7.2 Confidentiality - data treatment | |
Information on air pollution is not subjected to the protection of statistical confidentiality, since according to the Act 137/2010 Coll. on air, the operators of air pollution sources are obliged to provide information to public on air pollution caused by emission form their sources and about implemented measures to reduce this air pollution. |

---|---|
11.1 Quality assurance | |
Quality Declaration expresses the basic ideas and commitments of the President and top management of the Statistical Office of the Slovak Republic (SOSR) for the Quality Policy as well as increasing efficiency and effectiveness of the integrated management system of the SOSR. Quality policy is based on the mission of the SOSR: to provide high quality and objective statistical products and services by keeping confidentiality of statistical data and by minimising burden on interested parties using effectively existing resources with the aim to support improvement of the information and intellectual capital of our customers. In this way we want to contribute to reduce risks and improve effectiveness in their decision making processes and so to support the sustainable development of the Slovak Republic as the part of EU. Quality manual (only available in Slovak) describes the documented procedures of the quality system that are used for implementation and continuous improvement of the quality management system in SOSR. It contains a description of the quality management system and the fulfillment of requirements ISO 9001 standards. Application of the manual in practice ensures that all activities that have an impact on the quality of the products created are planned, managed, reviewed, evaluated and meet requirements. The basis of the common quality framework of the European Statistical System is the European Statistics Code of Practice. |
|
11.2 Quality assessment | |
Good data quality of AEA statistics is ensured by applying sound methodology for compilation of the AEA according to the Eurostat manual and by in-depth data checks within validation process. |

17.1 Data revision - policy | |
SOSR distinguishes the following revisions: from the content point of view the reason of the revision is -incorporation of better quality data based on a more complete source, including replacing imputations with collected data, -correction of data as a result of updating seasonal factors and changing the base period, -data modification based on more accurate methodology (in concepts, definitions and classifications) and changes in statistical methods, -performing corrections in source data and calculations. in terms of time the revisions are divided into -ordinary revisions - are revisions without significant modifications of the methodologies; these are usually more significant data corrections, including large values obtained from new sources; they are carried out periodically on precisely set up dates, to update monthly and quarterly data, until the next publication of the data, -annual revisions - are revisions that are made when all monthly and quarterly data are available and more detailed results from annual surveys are already available, -extraordinary and major revisions - are revisions of definitive data due to significant methodological changes resulting from revision of methodologies, changes in procedures and statistical-mathematical calculation methods or data corrections; an extraordinary revision may result (e.g. by changing the definition) in break in time series data comparability. |
|
17.2 Data revision - practice | |
Possible changes in methodology are communicated after their implementation in the form of methodological notes or footnotes. Changes/improvement of the methodology implemented within the grant projects are described in the respective implementation reports available on the website of Slovak Hydrometeorological Institute: https://oeab.shmu.sk/en/about-us/projects.html. |
18 Statistical processingUp | |
---|---|
18.1 Source data | |
The main source of data for GHG emissions is the Annual GHG Emissions Inventory submission that is reported to the UNFCCC. GHG emissions balance is based on the annual statistical data provided by the Statistical Office of the SR, data from the EU Emission Trading System (EU ETS), data collected in the National Emissions Information System (NEIS) and information from various national and international organisations (e.g. EUROCONTROL). In the case of air pollutants, the main source of input emissions data is the National Emission Information System (the NEIS database) which covers medium and large stationary sources of air pollution. Operators of large and medium air pollution sources are obliged to report, on annual basis, specific data on the operation. Data obtained from operators are gathered in the NEIS database. The NEIS database covers emissions from energy and industry sectors, partly fugitive emissions and emissions from the waste sector. The emissions inventory for other sectors is annually compiled by applying calculations based on the activity and auxiliary data provided by the Statistical Office of the SR and by applying international methodologies (agriculture and waste sectors) or national methodologies (households sector). |

18.5 Data compilation | |
In the case of GHGs emissions from stationary air pollution sources, the different approaches are applied depending on different sectors. For compilation of data for energy and industry sector energy-first approach is applied taking into consideration specific national circumstances. Allocation of emission arising from these sectors is based on information from energy statistics and from Physical energy flow accounts (PEFA). As regards GHGs emissions from agriculture and waste sector, the inventory-first approach is used. It means that emissions from GHGs inventories for these sectors are allocated to NACE Rev.2 categories on the basis of value added of particular NACE Rev.2 economic activities and taking into consideration specific national circumstances. The national methodology for allocation of emissions from transport sector (mobile air pollution sources) to NACE Rev.2 categories and households is specified in the document “Road transport allocation method of the SR“ which is available on CIRCA BC in the folder Environment Statistics, Indicators and Accounting > Physical environmental accounts > Road transport allocation to NACE and households > Inventory of country methods - document SK-Description_v2.docx. The national methodology for calculation of emissions from households’ heating is described in the document “Description of methodology for households’ heating“. The methodology for compiling the air emissions account is described in detail in technical implementation report on the project titled “Quality improvements of the air emission accounts and extension of provided time-series”. |
