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.
