One of the ways in which sustainability is applied to finance is the practice of responsible investment (SRI), on the basis of which environmental, social and / or governance considerations are integrated with the evaluation of a financial nature. The SRI is implemented with the inclusion of ethical indices of listed companies that meet the main criteria of environmental, social and economic responsibility or that do business according to defined ethical principles as regards its stakeholders.
