The ratings, which are free to access, were launched on 1 March and assess funds on their environmental, social and governance (ESG) factors.
They will also be made available on the Morningstar Advisor Workstation, the company’s practice management platform for financial advisers.
The ratings agency now provides sustainability ratings for roughly 21,000 mutual funds and ETFs, together responsible for $13trn (£9.2trn, €11.7trn) of assets under management.
Fund ranking
Morningstar Sustainability Ratings are underpinned by company and stock holding ESG research and ratings from Sustainalytics, with funds then ranked according to their proprietary category as low, below average, average, above average, and high.
Steven Smit, head of sustainability at Morningstar, said: “One of Morningstar’s core values is ‘investors first.’ We are making our Sustainability Ratings available for free to users on our global investor websites.
“We think the ratings will be most effective if they are made widely available and placed in the hands of ultimate fund owners and advisers.
“For the first time, approximately 10 million investors will have access to an independent, standardised sustainability assessment to include in their investment decisions.”
