Statistical presentation | |
Data description | The table about the emissions of pollutants in the air contains information from the National Statistical Institute (NSI) and Executive Environmental Agency at the Ministry of Environment and Water. The emissions are estimated by using a balance method based on the indicators: consumed fuels, calorific value, quantity of produced output and invested raw materials, as well as emission factors applicable for the respective pollutants. |
Classification system | The classification used according EMEP/EEA guidebook 2023 of: · sources of emissions; · fuels; · treatment facilities and measures to protect the atmosphere. |
Sector coverage | The statistical survey includes enterprises of all economic activities which operation is linked with the formation of emissions. |
Statistical concepts and definitions | Concepts and definitions are used according to EMEP/EEA guidebook 2023. |
Statistical unit | Firms, enterprises, local units, which activity is directly or indirectly connected with the formation of emissions. |
Statistical population | Economic subjects, which composition of activities includes:
|
Reference area | Total for the country and some industrial regions. |
Time coverage | 1992 - 2022 |
Base period | Not applicable. |
Statistical processing | |
Source data | Emissions are determined on the basis of data from: · The official national inventories of air emissions under the Convention on Long-range Transboundary Air Pollution and the United Nations Framework Convention on Climate Change; · Data from an annual specialized statistical survey; · Data from energy sector statistics, and PRODCOM - statistics by product . |
Frequency of data collection | Yearly |
Data collection | The data are collected by Information System. Data on emission sources are provided by all economic entities in the activity, which include: processes for electricity production (covered by the consumed fuels); processes in the production of other products (covered by consumed raw materials, manufactured products, etc.). |
Data validation | Comparing the data with those reported in the previous year concerning incorrect measure units and incorrect data by code on fuel of heating and industrial processes. |
Data compilation | The emissions are estimated by using a balance method based on the indicators: consumed fuels, Sulphur contents, calorific value, quantity of produced output and invested raw materials, as well as emission factors applicable to the respective pollutants. |
Adjustment | Not applicable. |
Quality management | |
Quality assurance | · European Statistics Code of Practice; · A common framework for quality management in the National Statistical System. |
Quality assessment | Not applicable. |
