This paper conducts a systematic review of the research work in the field of sustainable investment for identifying research gaps and laying down research agenda for the future. Articles on sustainable investment published in journals indexed at the Web of Science during 1989 and 2018 (so far) are reviewed for the purpose of this research. A total of 225 papers were found through the search criteria, out of which 213 papers were selected for review. The paper identifies gaps in the literature that can be considered as opportunities for future study. The analysis of these articles led us to note the need for an agenda that can present a holistic framework of sustainable investment with lesser variations and increased acceptability. The research agenda proposed by the paper may help researchers in framing their research problems around the gaps identified. Sustainable investment is a potential solution to social and ecological issues by transforming the financial markets to have more accountability for their impacts. Therefore, it is important to carry out extensive research in this field so as to develop it as an applied field of investment. There has so far been no attempt to perform a systematic review in the field of sustainable investment for a period of 20 years, as has been made in this paper.
