Independent investment research firm Morningstar announced today a significant expansion in the funds covered under its Morningstar Sustainability Rating, by incorporating funds' investments in sovereign debt, in addition to corporate securities, through the inclusion of Country Risk Ratings from ESG ratings and research provider subsidiary Sustainalytics. Morningstar completed the acquisition of Sustainalytics in July 2020. Morningstar introduced its Sustainability Rating in 2016, aiming to help investors use ESG information to evaluate portfolios. In 2019, the company updated the tool by replacing Sustainalytics' company ESG Rating with its ESG Risk Rating, which measures the degree to which a company's economic value may be at risk due to ESG issues.
