The Dow Jones Sustainability Indices were launched in 1999 as the first global sustainability benchmarks. The indices are offered cooperatively by RobecoSAM and S&P Dow Jones Indices. Each year, they invite the world's 2,500 largest companies, classified as 60 RobecoSAM industries to report on their sustainability performance. The results of the Corporate Sustainability Assessment provide an in-depth analysis of economic, environmental and social criteria. The indexes serve as benchmarks for investors who integrate sustainability considerations into their portfolios and provide an effective engagement platform for companies that want to adopt sustainable best practices.
