S&P 500 Environmental, Social, and Governance Index In May 2019, our Indices Division expanded its Core Environmental, Social, and Governance offering, with the launch of a global suite of Environmental, Social, and Governance Indices which includes the S&P 500 Environmental, Social, and Governance Index. The objectives of the S&P 500 Environmental, Social, and Governance Index are to provide a similar risk/return profile to the S&P 500 and to avoid companies that are not managing their business in line with Environmental, Social, and Governance principles.
