Özet
The role of financial systems in combating climate change is becoming increasingly decisive. The primary porpose of this research is to investigate the impact of green finance on carbon emissions in the United Kingdom and to highlight the role of the financial system in driving environmental transformation. To this end, the Green Finance Index was developed, and Fourier-based econometric methods, Panel Fully-Modıfıed Ordinary Least Squares, Dynamic Ordinary Least Squares, and Canonical Cointegrating Regression, were employed in the analysis. The research's control variables are hydrogen energy Research & Development expenditure, per capita income, and high-tech product exports. Empirical findings indicate that a 1% increase in Green Finance Index results in a reduction of approximately 7.6% in per capita carbon dioxide emissions. This result demonstrates that aligning the financial system with environmental sustainability plays a crucial role in reducing carbon dioxide emissions. This finding directly supports the United Nation's Sustainable Development Goal 9 and 13. Furthermore, increasing hydrogen energy Research & Development expenditure reduces carbon dioxide emissions, while increases in per capita income and high-tech exports increase carbon dioxide emissions. From a policy perspective, the United Kingdom is recommended to revive financial instruments similar to the now-cancelled Green Taxonomy Program, integrate hydrogen energy technologies with renewable energy, and expand green financing channels.
