    Why issue green bonds? Examining their dual impact on environmental protection and economic benefits by Di Zhou, Alexios Kythreotis

    Published 2024-12-01
    “…Abstract This article explores two primary questions: first, whether the issuance of green bonds contributes to environmental protection, particularly regarding their performance after the adoption of net-zero emission policies; and second, whether issuers of green bonds can have economic benefits. Using the Difference-in-Differences (DID) model to analyze green and conventional bonds issued from 2013 to 2023, the study finds no significant correlation between green bond issuance and CO2 emissions following net-zero adoption. …”
