EU Membership, Institutional Governance, Economic Development and Environmental Sustainability: Empirical Evidence from the Balkan Economies

This paper examines the intricate relationship between European Union (EU) membership, institutional governance, economic development, and environmental sustainability in the Balkan economies from 1998 to 2023. A comparative analysis was conducted to highlight the differences between the EU and non-EU Balkan states, with a focus on the role of institutional governance and economic development. Utilising data from the Sustainable Development Goals indicators and the Worldwide Governance Indicators (WGI), the study employs the Prais-Winsten regression method to address issues of autocorrelation and heteroscedasticity in the panel data. This method enhances the robustness of the empirical analysis and provides more reliable insights into the effects of economic and governance variables on CO2 emissions. The findings contribute to a deeper understanding of the impact of EU membership and institutional governance on environmental sustainability, offering insights into the effectiveness of environmental policies in the context of economic development and governance quality. Governance indicators such as political stability and regulatory quality have a more substantial negative relationship with the climate indicator in EU Balkan states than in their non-EU counterparts. The study also highlights the disparities between the two groups of Balkan countries in terms of environmental regulations and energy portfolios. The paper concludes with implications for policymakers in the Balkan region, emphasising the importance of strong institutions and governance frameworks in achieving environmental sustainability goals.
