AbstractThe exceptional rise in overall economic activities has deteriorated environmental sustainability around the world. However, countries around the globe are implementing strategies for reaching the global climate objective. For this purpose, OECD countries committed many efforts, although their pledges and results are not parallel to the level of the Paris Agreement's ambition. This study examines the impact of eco-innovation, environmental taxes, and renewable energy consumption on the environmental performance of selected OECD countries over the period of 2006 to 2020. This study uses the generalized method of moments (GMM) and instrumental variables 2 stage least square (2SLS) methods. For robustness checks, this study uses a quantile regression approach. We conclude that an increase in the adoption of renewable energy and green innovation has a statistically significant impact on controlling CO2 emissions. Moreover, the empirical model is expanded by incorporating environmental taxes as an explanatory variable. The expanded model showed that the imposition of environmental taxes has a detrimental impact on the reduction of CO2 emissions. Moreover, on the contrary, an increase in economic activities, measured by GDP, is responsible for rising CO2 emissions in OECD countries. In light of the results we obtained, policy recommendations are provided.
