Established in 1999, the Dow Jones Sustainability indices are compiled annually by S&P Dow Jones and the Zurich-based RobecoSAM, a sustainable investment specialty firm. They were the first organizations in the world to track the financial performance of companies that lead their respective industries in managing economic, environmental and social issues with a strong focus on long-term shareholder value. The indices serve as benchmarks for investors who integrate sustainability considerations into their portfolios.
