The study was aimed at investigating the dynamic relationship between environmental taxes, green financing, and carbon dioxide (CO) emissions in Brazil, China, India, and South Africa from 1994 to 2019. To thoroughly examine the proposed relationship, a family of robust econometric methods is used to get reliable and accurate results. Our evidence indicates that green finance and CO emissions are negatively connected with each other. Similarly, positive relationship is found between environmental taxes and CO emissions. Additionally, environmental taxes and green finance are positively related as well. Further, the results of the Method of Moments Quantile Regression estimator indicate that green finance and CO emissions decrease in countries with higher pollution compared to those with lower pollution. Interestingly, environmental taxes only contribute to pollution in countries with higher emissions, whereas CO emissions increase environmental taxes in all sample countries. Lastly, green finance has a mitigating effect only in countries with greater pollution, and CO emissions have a negative rebound effect on green finance in countries with greater CO emissions. According to the evidence, green financing can be an effective tool for promoting environmental quality. By allocating the funds collected from environmental taxes to green financing, environmental sustainability can be promoted in sample countries.
本研究旨在调查巴西、中国、印度和南非 1994 年至 2019 年期间环境税、绿色金融与二氧化碳（CO）排放之间的动态关系。为了彻底检验所提出的关系，我们使用了一系列稳健的计量经济学方法以获得可靠和准确的结果。我们的证据表明，绿色金融与 CO 排放之间呈负相关关系。同样，环境税与 CO 排放之间也存在正相关关系。此外，环境税与绿色金融之间也呈正相关关系。进一步，矩量法分位数回归估计的结果表明，与污染水平较低的国家相比，污染水平较高的国家的绿色金融和 CO 排放会减少。有趣的是，环境税仅会对排放水平较高的国家造成污染，而 CO 排放则会增加所有样本国家的环境税。最后，绿色金融仅在污染水平较高的国家具有缓解作用，而 CO 排放对 CO 排放水平较高的国家的绿色金融具有负向的回弹效应。根据证据，绿色金融可以成为促进环境质量的有效工具。通过将环境税征收的资金用于绿色金融，可以促进样本国家的环境可持续性。
