MSCI ESG Ratings aim to measure a company’s management of financially relevant ESG risks and opportunities. We use a rules-based methodology to identify industry leaders and laggards according to their exposure to ESG risks and how well they manage those risks relative to peers. Our ESG Ratings range from leader (AAA, AA), average (A, BBB, BB) to laggard (B, CCC). We also rate equity and fixed income securities, loans, mutual funds, ETFs and countries.
