Environmental taxes and renewable energy consumption are becoming central policy instruments in countries especially in European Union (EU) countries to enhance environmental sustainability; however, no attention has been given to eco-innovations in the nexus between environmental taxes and carbon dioxide emission. This study investigates the effect of environmental taxes, innovations, and renewable energy consumption on CO2 emissions in 26 EU countries from 2000 to 2020. Panel quantile regression was employed for analysis where the results show that environmental taxes have both positive and negative influence on CO2 emissions across quantiles in different models, whereas renewable energy consumption considerably reduces carbon emissions. Economic growth causes an increase in CO2 emissions; however, the financial progress greatly reduces CO2 emissions. Eco-innovations and its square term have a negative influence on carbon emissions which shows that eco-innovations significantly reduce carbon dioxide emission. The findings have significant implications for public policy in the sample countries, notably in terms of promoting renewable energy sources and transitioning to green growth through eco-innovations in order to achieve environmental sustainability.
环境税和可再生能源消费正成为各国，尤其是欧盟国家增强环境可持续性的核心政策手段；然而，人们尚未关注环境税与二氧化碳排放之间关系中生态创新的作用。本研究调查了 2000 年至 2020 年间 26 个欧盟国家环境税、创新和可再生能源消费对二氧化碳排放的影响。采用面板分位数回归进行分析，结果表明，在不同模型中，环境税对二氧化碳排放的影响在各分位数上既有正有负，而可再生能源消费则大大减少了碳排放。经济增长导致二氧化碳排放增加；然而，金融进步大大减少了二氧化碳排放。生态创新及其平方项对碳排放有负面影响，表明生态创新显著减少了二氧化碳排放。这些发现对样本国家的公共政策具有重要意义，特别是在促进可再生能源和通过生态创新向绿色增长过渡以实现环境可持续性方面。
