The Role of Green Bonds in Financing Sustainable Infrastructure Projects: Evidence from Global Markets

Abstract

This study investigates the impact of green bonds on financing sustainable infrastructure initiatives, focusing on their development and influence from 2010 to 2023. Utilizing a detailed dataset of global green bond issuances categorized by region and sector, the research evaluates trends and identifies key drivers of market growth. It includes case studies such as the French sovereign green bond and the City of Paris green bond, which illustrate the real-world applications of green bonds and their role in reducing CO2 emissions. The findings show that global green bond issuance exceeded $510 billion, with renewable energy projects receiving the largest portion of funding and making significant contributions to CO2 reduction efforts. Additionally, the analysis points out adherence to the Green Bond Principles, highlighting areas needing improvement in post-issuance reporting. Overall, the results emphasize the vital role of green bonds in facilitating climate finance and promoting a sustainable, low-carbon economy. The study calls for stronger policy frameworks and financial incentives to encourage further growth in the green bond sector.
