To assess the portfolios' performance for 2004-2019 the Fama-French 3-factor, Carhart 4-factor, and Fama-French 5-factor models are used. In total, 48 ESG integrated portfolios were constructed and analyzed.

Several studies have shown that sustainable and responsible investment (SRI) strategies offer a solution to this challenge. With SRI, investors can include companies' sustainability factors via environmental, social, and governance (ESG) information in th
