The article presents the results of monitoring the state of the air environment of Lviv region in 2020. The main sources of pollution are identified and statistical data on emissions of pollutants into the atmosphere are given. The aim of the work is to analyze the state of the environment, natural resources of Lviv region, trends in their changes and environmental measures. Volumes of pollutant emissions from stationary sources of air pollution from enterprises, institutions and organizations of Lviv region were determined by conducting an inventory of stationary sources of pollutant emissions into the air, types and volumes of pollutant emissions into the atmosphere by stationary sources, equipment facilities of the region.
