Addressing climate challenges and achieving the Sustainable Development Goals (SDGs) necessitate a deep understanding of how green policies influence carbon emissions. Therefore, this study explores the impact of green finance, innovation, and taxation on carbon emissions in OECD countries while accounting for economic growth, renewable energy, and energy productivity. Utilizing the method of moment quantile regression analysis, we find that green finance, taxes, and innovation significantly reduce emissions in OECD economies. The impacts of green finance and taxes exhibit an increasing trend, with higher coefficients at higher quantiles. Conversely, green innovation shows a decreasing trend, with coefficients showing lower magnitude at higher quantiles. The results also show that renewable energy and energy productivity significantly mitigate emissions. In contrast, economic growth correlates positively with CO₂ emissions. Our findings highlight the need for robust policies that invest in clean technologies, broaden green financial instruments, and enhance energy efficiency. In line with the frameworks established at COP28, we emphasize the pivotal role of both public and private funding in facilitating the transition to a low-carbon economy.

三大绿色因素：创新、财务和税收 — 绩效分析和未来影响


应对气候挑战和实现可持续发展目标 （SDG） 需要深入了解绿色政策如何影响碳排放。因此，本研究探讨了绿色金融、创新和税收对经合组织国家碳排放的影响，同时考虑了经济增长、可再生能源和能源生产力。利用矩分位数回归分析方法，我们发现绿色金融、税收和创新显著减少了经合组织经济体的排放。绿色金融和税收的影响呈增加趋势，分位数越高，系数越高。相反，绿色创新呈下降趋势，系数在较高的分位数上显示较低的幅度。结果还表明，可再生能源和能源生产率显著减少了排放。相比之下，经济增长与 CO₂ 排放量呈正相关。我们的研究结果强调了制定强有力的政策的必要性，这些政策投资于清洁技术，拓宽绿色金融工具，并提高能源效率。根据 COP28 建立的框架，我们强调公共和私人资金在促进向低碳经济过渡方面的关键作用。
