Abstract: Given the current context, with phenomena such as dramatic climate change, water, air, soil pollution, etc., the complex relation between environmental degradation and economic growth is intensely debated in the academia as well as in worldwide politics. This study examines the relationship between carbon dioxide emissions, gross domestic product, energy consumption, and urbanization rate in Romania and Bulgaria over 1980–2019 period. For this purpose, we have applied the ARDL bounds testing approach and, to validate the robustness of the results, we have used the VEC Granger model. The results showed that there are long term relationships between CO2 emissions per capita and the determinant factors taken into account in both countries; however, while the inverted N-shape of EKC is significant in the case of Bulgaria, this does not happen in the case of Romania although the model which includes the inverted U-shape of EKC is significant for both countries. Considering the fact that both Romania and Bulgaria are emerging economies which, despite having made significant progress, are still in search of a path towards sustainable development, such a study may constitute a good starting point and may suggest some action directions in terms of sustainable development policies.
