6. Bulgarian National Emission Inventory System In Bulgaria the emission estimates are calculated according to the EMEP/ CORINAIR Methodology. In Bulgaria the emission estimates are calculated according to the EMEP/ CORINAIR Methodology. Data from the emission inventory are collected at regional and national level. Data from the emission inventory are collected at regional and national level. All emission data are stored in the National Database in EEA. All emission data are stored in the National Database in EEA. The emission data are updated every year. The emission data are updated every year.

7. Bulgarian National Emission Inventory System EMEP/CORINAIR Methodology: The nomenclature - SNAP – “Selected Nomenclature for sources of Air Pollution” is based on three different levels of categories, sub- categories and individual activities : The nomenclature - SNAP – “Selected Nomenclature for sources of Air Pollution” is based on three different levels of categories, sub- categories and individual activities : The upper level (11 items) corresponds to the main classical categories generating emissions of pollutants; The upper level (11 items) corresponds to the main classical categories generating emissions of pollutants; The intermediate level reflects the structure of activities according to engineering and socio – economical aspects; The intermediate level reflects the structure of activities according to engineering and socio – economical aspects; The lowest level enumerates all relevant activities to be included. The lowest level enumerates all relevant activities to be included.

12. Bulgarian National Emission Inventory System Emission factors Up to 2005 the emissions of air pollutants are calculated based on the activity data and emission factors, set in National CORINAIR 94 methodology. Up to 2005 the emissions of air pollutants are calculated based on the activity data and emission factors, set in National CORINAIR 94 methodology. In 2005 the MoEW/EEA developed a new National Emission Inventory Methodology. It is developed by adapting the 3rd edition of the EMEP/CORINAIR Atmospheric Emission Inventory Guidebook for the Bulgarian conditions, taking into account the national specificities concerning the respective activity, technologies and equipment.
