The economy of Bulgarian Districts and its effect on environmental performance

The aim of this study is to examine on the relationship between economic growth and environmental performance in the 28 Bulgarian districts for the period between 2010 and 2016. The results show that when in the cases where CO2 emissions are medium, the relationship with the economic growth is very weak. However, for those districts with higher CO2 emissions per capita there is a significant relation with the economic variables. This would mean that economic growth would have a strong effect on the air quality only after certain amount of CO2 emissions.
