Integrating multiple ESG investors' preferences into sustainable investment: A fuzzy multicriteria methodological approach

摘要

The integration of environmental, social and governance (ESG) criteria into the evaluation process of assets is a theme that is widely accepted among socially responsible investors. In this process, however, the integration of investors' preferenceS has not been adequately developed. The challenge is to integrate the preferences of heterogeneous investors- not only conventional investors but also investors who are particularly sensitive to sustainability issues (socially responsible investors)-considering that socially responsible investors are not necessarily homogeneous. This paper attempts to address this challenge by developing a methodological approach based on an application of fuzzy multicriteria decision-making methods (MCDM) to integrate ESG investors' preferences, as jointly considered. Because investors' preferences may vary depending on which material aspects are considered within a sector, this study has been tested using clothing-sector data. Results confirm the usefulness of the methodological approach proposed for a proper generation of a 'commercial solution' that integrates the preferences of various investors and simultaneously is consistent with individually defined preferences.
