The paper presents a valuable contribution by examining the relationship between financial development, quality growth, and environmental sustainability, but several critical points warrant attention. The methodology for constructing composite indices lacks transparency, particularly regarding variable selection and weighting, which may introduce bias. Additionally, the handling of cross-sectional dependence and multicollinearity in panel data appears insufficient, potentially affecting the robustness of the findings. While the policy recommendations are insightful, they are overly general and fail to address the nuanced differences between EU countries. Greater clarity and rigor in these areas would significantly strengthen the study’s impact and reliability.
