The S&P Global Corporate Sustainability Assessment

The Corporate Sustainability Assessment (CSA) empowers you to leverage the unique expertise and the proprietary methodology and database underlying the world’s most renowned sustainability indices.

Established in 1999, the CSA has become the basis for numerous ESG indices over the last two decades. S&P Global acquired the CSA in 2019, which included the transition of the related ESG ratings and ESG benchmarking teams and that now operate out of S&P Global Switzerland.

Key Facts

  • Companies are selected for inclusion in the Dow Jones Sustainability Indices (DJSI), S&P 500 ESG and several other sustainability indices in part based on their results in the S&P Global CSA
  • A growing number of companies participate in the assessment and use their results to benchmark their sustainability performance vis-a-vis peers
  • The CSA applies a best-in-class approach, meaning no industries are excluded from the assessment, and the CSA compares companies across 61 industries via questionnaires assessing a mix of 80-100 cross-industry and industry-specific questions
  • On the basis of their performance, companies receive scores ranging from 0 to 100 and percentile rankings for approximately 20 financially relevant sustainability criteria across economic, environmental and social dimensions
  • All assessed companies' industry rankings are published on the Bloomberg Platform

A History of Innovation

What started out as a paper-based questionnaire in 1999 has now grown into one of the world’s most extensive corporate sustainability databases. To ensure that our analysis remains focused on financially material criteria, we continuously refine our methodology to reflect new sustainability trends that are likely to have an impact on companies’ competitive landscape.

Our CSA timeline highlights the key innovations to the questionnaire as well as some of the major technological developments, environmental challenges, and global events that have influenced our methodology over the years.
