The Morningstar Sustainability Rating for funds helps investors measure portfolio-level risk from environmental, social, and governance, or ESG, factors. To evaluate portfolios, Morningstar uses ratings from our partner Sustainalytics that measure a company's material ESG risk. We then roll up the company-level scores on an asset-weighted basis to get a portfolio score. A fund with high ESG risk relative to its Morningstar Global Category would receive 1 globe. A fund with low ESG risk would receive 5 globes.
