摘要

This study delves into the intricate relationship between environmental taxes, renewable energy, environmental regulations, environmental sustainability, and energy security in the Group of Seven (G7) countries Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States from 2000 to 2022. The method of moment quantile regression approach shows that environmental taxes, renewable energy, and environmental policy play a significant role in reducing ecological footprints and promoting energy security; conversely, globalization and economic growth exacerbate environmental degradation by increasing ecological footprints in G7 countries. It also has a negative effect when reducing energy security in G7 countries. However, to clarify the casualty directions of the variables, we applied the D-H causality, and the existence of bidirectional causality observed between renewable energy, environmental regulations, and energy security risks suggested a dynamic interplay that required continuous monitoring and adaptation of policies. Additionally, based on the study outcome, we propose that the direct proceeds from environmental taxes fund renewable energy projects, energy infrastructure, and climate adaptation initiatives. This reinvestment can bolster economic growth while enhancing sustainability.
