Abstract

Humans have long depended on nature for survival, yet technological advancements have often harmed the environment. However, technology does not necessarily require environmental destruction. Innovations in environmental technologies can support sustainability and reduce climate change impacts. Despite their importance, environmental patents - key indicators of green innovation - are understudied. This paper investigates the effects of environmental patents, environmental taxes, renewable energy consumption, and economic growth on CO2 emissions in OECD countries from 1995 to 2020. Using the Dumitrescu-Hurlin panel causality test, the study finds mutual causality between variables. These findings highlight the complex relationship between economic policies and environmental outcomes. As climate concerns grow, it becomes increasingly vital to understand how policy tools such as taxes and innovation influence emissions. The study contributes to the literature by offering insights into how environmental technologies and economic instruments can mitigate climate change.
