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.

Within the framework of the Corinair - CORe INventory AIR emissions, the European Environment Agency (EEA) and its European Topic Centre on Air and Climate Change (ETC-ACC) have developed a set of software tools to support European countries in compiling annual air emission inventories. These tools allow for a transparent and standardized, hence consistent and comparable data collecting and emissions reporting procedure in accordance with the requirements of international conventions and protocols and EU legislation.
