Portfolio ESG rankings vs. peers
Many investors want to see a snapshot view that shows a portfolio’s aggregate ESG ratings or rankings, and many value the independence of an assessment that is based on third-party data.
Carbon intensity
Carbon dioxide and other greenhouse gases (GHG) trap thermal radiation from the earth’s surface, sustaining natural life.

Linking impact and performance
Often, the same elements that create environmental and social benefits are driving positive financial performance.
Read postThe Morningstar Rating™ for funds, or "star rating," is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product's monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and ten-year (if applicable) Morningstar Rating metrics. The weights are: 100% three-year rating for 36 to 59 months of total returns, 60% five-year rating/40% three-year rating for 60 to 119 months of total returns, and 50% ten-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the ten-year overall star rating formula seems to give the most weight to the ten-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods. Ratings do not take into account the effects of sales charges and loads.
