Abstract

Environmental, social, and governance (ESG) investing is synonymous with sustainable investment for socially responsible investors. Unfortunately, the diversity of ESG investing remains unattended amidst the growth in ESG literature, as the academic literature focuses dominantly on measuring performance. An understanding of a wide range of subjects entailing ESG is required before future research on ESG investing is performed. To overcome the challenge, this systematic literature review uses bibliometric mapping to reveal four significant research themes within the ESG investing literature: investor behavior and motivations for ESG investing; cost and risk mitigation in ESG investing; portfolio screening and ESG investing; and ESG performance. The review critically examines each theme and broadens the research agenda for future studies. In addition to the significant themes, this paper also discusses theoretical and recent research trends in the ESG investing literature. The review identifies clashes and crossovers between these themes to appropriately interpret one theme using another and emphasizes the heterogeneity in ESG investing. Lastly, discussion over concerns and criticisms of ESG investing highlights greenwashing as a major cause of concern for investors.
