Intro - ESG Indexes

Our ESG index story begins in 1990, with the launch of the Domini 400 Social Index — now the MSCI KLD 400 Social Index — as one of the first socially responsible investing indexes. Since then, we have enhanced our ESG index capability to reflect the evolving needs of our investors.

We have learned over that time that investors have a wide range of motivations for seeking ESG strategies. At MSCI, you can choose the index approach that best fits your objectives.

That could mean integration, such as including companies with strong ESG profiles; screen portfolios for controversial activities and companies, target companies seeking to generate specific sustainable outcomes.
