Abstract

The main air pollutants in Serbia are primary and secondary suspended particles, sulfur dioxide, carbon dioxide and monoxide, and nitrogen oxides. This paper aims to calculate the ecological efficiency based on nitrogen oxide emissions from 2015 to 2019 for medium-sized enterprises that are significant sources of air pollution in Serbia. The ecological efficiency indicator is determined as the ratio of the enterprises' operating income and nitrogen oxide emissions annually. The analysis results of nitrogen oxide emissions in Serbia during the five years show a declining trend until 2018, when emissions are lowest. The analyzed mediumsized enterprises continuously emit nitrogen oxides in the observed period. Most of the analyzed enterprises recorded a decrease in nitrogen oxide emissions in the second part of the observed period, indicating improved ecological efficiency. However, along with reducing nitrogen oxide emissions, some enterprises recorded a decrease in operating income, operating and net results or even negative results. A bad trend of ecological efficiency is recorded by a mediumsized enterprise engaged in paper and cardboard production.
