Green Bonds and Corporate Environmental Performance: A Quantitative Analysis of Post-Issuance Impact in Asia-Pacific Markets
Main article
Abstract
The expansion of green bond markets in the Asia-Pacific region has accelerated the integration of environmental objectives into corporate finance. This study investigates whether and how the issuance of green bonds enhances corporate environmental performance in the post-issuance period. Drawing on a balanced panel of publicly listed manufacturing and energy firms from 2015 to 2024, we employ a difference-in-differences (DID) approach combined with firm-level fixed effects to assess changes in carbon intensity, energy efficiency, and waste reduction following green bond issuance. The empirical results indicate that green bond issuance is associated with statistically significant improvements in environmental performance, particularly in reducing greenhouse gas emissions and increasing renewable energy adoption within two years after issuance. The magnitude of these improvements is stronger among firms operating in countries with stringent green finance regulations and transparent environmental disclosure standards. Furthermore, industry-specific analysis reveals heterogeneous effects across sectors, implying that project allocation and technology intensity moderate the environmental outcomes of green bond financing. By providing robust evidence on the real environmental impact of green bonds, this study contributes to the growing literature on sustainable finance and offers practical implications for policymakers and investors seeking to strengthen the credibility and effectiveness of green financial instruments in achieving regional climate objectives.
