The study analyses the influence of environmental taxes, renewable energy, economic growth, green innovation and financial development on environmental sustainability in different OECD countries .The results confirm a negative relationship between environmental taxes and sustainability. Furthermore, it is evident that economic growth significantly improves environmental sustainability, supporting the “double dividend” hypothesis, which argues that revenues generated by environmental taxes can be used to finance tax reductions in other areas while contributing to the regulation of environmental degradation. Our findings also show that renewable energy and green innovations play a key role in improving environmental sustainability and have some positive and negative impacts of such variables.
