The NEIS project (National Emission Information System of Slovak Republic) started in 1998 within the PHARE support program, particular development supported in 2001 – 2004 by DANCEE fund. The project is continually supervised and financed by SHMU and Slovak Ministry of Environment.
The most important goal of the NEIS project is to give a very efficient tool to the Environmental Department of the District Office to improve the process of collecting and verifying the air pollution data. Consequently the data are transferred and imported to the central database on SHMU, to enable reporting and presentation.
National Emission Information System in Slovakia represents a strictly bottom - up implemented approach (in the sector of industrial and power emissions). It comes to this, that the data are collected on the lowest level of power or technological processes producing the emissions. In this case the specific local conditions, measurements and individual emission factors could be considered. The approval of this data is realised on the lowest institutional level of District Offices. The transfer of the data to the central national level as well as international authorities has been computerised. Such approach enables, the quality and transparency of air emission data available is rather be high in compare with other methods based mostly on inexact statistical data.
NEIS in accordance with Act No. 137/2010, as amended by Act No. 318/2012 Coll., Decree No. 410/2012 Z.z. and the Act 401/1998 on Air Pollution Charges allows extensive collection, validation and reporting of data including 320 different types of data on a set of 19 forms and sub-forms related to 12,000 stationary sources of air pollution operated by 6300 legal entities of the SR. Whereas the data are annually electronically processed and validated at 79 district offices.
