Incorporating Green Bonds into Portfolio Investments: Recent Trends and Further Research

Abstract

The analysis of green bonds and the composition of portfolio investments has gained importance in recent research. The current global context of Sustainable Development Goals requires investors to be environmentally, politically, and socially sustainable, in which the financing of green innovations has occupied a central role. Through the Web of Science and Scopus databases, we focused on analyzing recent trends and further research on green bonds into portfolio investments. The study was performed on 102 studies using Tree of Science (ToS), VOSviewer, and Bibliometrix techniques. We recognize the principal authors and sources, the most influential studies, and the bibliography coupling of studies and authors to identify their importance in the topic analysis. In order to expand the green bond market, particularly at the small and medium enterprise level, more policy instruments are needed. Thus, this study provides an extensive understanding of the research status of the analysis of green bonds and portfolio investments research as an essential input for market participants, researchers, policymakers, and decision-makers.
