Present state of air quality is determined according to emission and imission situation of basic pollutants. According to obtained information about the state of air quality the development of imission and emission has at the present time decreasing tendency caused especially by industrial production innovations in European countries, with slight rises renewable energy sources for electricity production, but especially the effort to improve the condition relates to the use of mandatory quotas and pollution charges in the European Union. The aim of the this article is the review of emission development in the year 1998 up to 2013 for Central European countries - Slovakia, Czech Republic and Poland and their comparison to the European average value of released emission. As pollutants were evaluated NOx and particulate matter PM10, PM2,5, which in the last few years contaminate the air and in particular the main environment.
