The Dow Jones Sustainability Indices (DJSI) began as one global index in 1999, comprising the top-ranked companies from each industry based on environmental, social, and governance criteria. The DJSI now includes many indices, including one for each world region. Each year, invited companies submit a questionnaire, which is scored and compared to peers. Only companies with the highest scores earn a listing.
