I have been interested in environmental issues and their relationship to all aspects of economic development for some years now. Every day there is more and more external pressure on companies to include environmental sustainability aspects in their performance evaluations. In this article I seek to analyze the relationship between financial variables and the environmental performance of companies, through a literature review approach resulting from a search of variables previously established in a database. The methodology used began with the identification of environmental and financial variables in the Refinitiv database, a provider of financial market data and infrastructure, and subsequently, the search of the identified variables (25 environmental and 14 financial) in the Scopus document database, which is a bibliographic database of abstracts and citations of scientific journal articles. From the selected documents, a classification of actors was made in 8 categories which are: Hedge Fund, Individual Investor, Insurance Company, Pension Fund, Sovereign Wealth Fund, Corporation, Bank and Trust and Investment Advisor. According to the search, the importance of ESG practices and the role of institutional investors in promoting sustainability is emphasized. With the results obtained, it was found that the environmental variables identified in the literature reviewed do have a relationship with financial variables. In fact, due to the growing interest in these environmental issues, new financial products linked to environmental aspects have been created, such as green bonds and/or carbon offsetting. A limitation during the development of the work was that of having received the search variables, which somewhat limited the possibilities of making some decisions during the study; for this reason, it would seem interesting to study in the future, the real effect or environmental impact of the presence of these financial variables in the environment of the actors (institutional investors) identified.
