"We screened the Morningstar US Sustainability Index to find some undervalued stocks that score well on ESG metrics. Sustainability assessments are provided to Morningstar by researcher Sustainalytics (of which Morningstar has a 40% ownership stake)."

[COMMENTARY] I’m delighted to see that Morningstar is starting to freely share some of the individual Sustainalytics stock ratings. This is good news for all investors who don’t have access to Sustainalytics individual stock ratings’ services.
