Abstract
This study examines the effects of environmental taxes, sustainable development level, and environmental protection expenditures on the ecological footprint in European Union countries. The analysis is conducted using a balanced panel dataset covering 24 countries over the period 1995-2021. The ecological footprint is used as the dependent variable, while environmental taxes, the Sustainable Development Index, and environmental protection expenditures are included as explanatory variables. The empirical procedure includes descriptive statistics, the VIF test, cross-sectional dependence tests, the Fisher-ADF panel unit root test, panel model selection tests, heteroskedasticity and autocorrelation diagnostics, Park-Kmenta FGLS and Beck-Katz PCSE estimations, the Delta homogeneity test, and the Dumitrescu-Hurlin panel causality test. The findings reveal that environmental taxes have a positive and statistically significant effect on the ecological footprint. In contrast, the Sustainable Development Index and environmental protection expenditures have negative and statistically significant effects, indicating that improvements in sustainable development performance and environmental protection spending contribute to reducing ecological pressure. The causality results also suggest dynamic interactions between the ecological footprint and the explanatory variables. Based on these findings, environmental taxes should be designed not merely as revenue-generating instruments but as policy tools that effectively transform environmental behavior, while environmental protection expenditures should be allocated in a more targeted and performance-oriented manner.
