Benefit from an independent assessment of your company's sustainability performance

The S&P Global Corporate Sustainability Assessment (CSA) is for companies looking to establish a sustainability baseline and gain independent insight into their sustainability performance relative to peer companies. Companies eligible for selected S&P Dow Jones indices are invited to participate in the CSA free of charge. Other companies can commission the assessment as a service.

Key information for companies interested in the CSA

Are you looking to establish a sustainability baseline and gain independent insight into how your company's sustainability performance compares with your peers and members of the prestigious Dow Jones Sustainability Indices? Learn all about the process and benefits of assessing your company’s sustainability performance in the CSA.


Which companies are invited to complete the CSA?

Each year S&P Global invites the largest global companies to participate in the Corporate Sustainability Assessment (CSA) free of charge. This year, S&P Global is extending the list of invited companies to over 10,000. The extended list of invited companies is made up of eligible constituents from the Dow Jones Sustainability Indices (DJSI) and the S&P ESG Index series. In addition, S&P Global invites companies that are of interest to the broader investment community and therefore part of S&P Global’s research universe.

Companies eligible for inclusion in the Dow Jones Sustainability Index (DJSI) series. Companies that are eligible for inclusion in any Dow Jones Sustainability Index will be invited based on their free float asset capitalization at the end of the year prior to the invitation (for the 2021 CSA: December 31, 2020).

Companies eligible for inclusion in the S&P ESG Index series. Companies that are not in the list of companies invited for consideration in any DJSI in 2021, but were included in selected S&P Dow Jones indices as of December 31, 2020 will also be invited to participate in the CSA this year.

Companies that are of interest to the broader investment community. S&P Global invited all companies whose sustainability performance is considered to be of interest to the broader investment community but that are not eligible for inclusion in one or more DJSI or S&P ESG indices. Invitations were sent out on June 15. If your company is on the CSA invitation list below, but you did not receive an invitation email, please complete this form to designate a company representative that we can reach out to regarding the review of your company's ESG assessment.

Which companies commission the CSA as a service?

Private companies can decide to commission the assessment in order to have their corporate sustainability performance evaluated as a service. The underlying methodology and assessment approach are similar for all companies participating in the CSA, making the results comparable with DJSI members and other invited companies. Contact our ESG Benchmarking team to learn more.

How does the assessment work?

From data to score

The CSA uses a consistent, rules-based methodology with specific approaches for 61 different industries. There are approximately 100 questions for each industry, with each question falling under one of approximately 23 different themes or criteria. The criteria, in turn, fall under one of the three dimensions: Environmental (“E”), Social (“S”), and Governance & Economic (“G”). Some criteria are common across industries, while others are industry specific. The CSA generates a total ESG score for every company covered, as well as individual scores for the three dimensions, with 100 being the best score in each case.

This graph visualizes the CSA. The size of the segments reflects the financial materiality assigned at each level as well as the weight applied in the score aggregation process. The CSA uses 61 industry specific sets of questions and weights.

Your CSA portal - secure, online, easy-to-use

The CSA is completed via our secure online questionnaire platform, the CSA Portal. The Portal substantially facilitates reporting, and after the first year of participation and can be prefilled with previous answers in subsequent years.

The CSA portal provides useful tools to efficiently manage the process to complete the questionnaire:

  • access a question-specific help function including background information on the rationale for each question/criterion as well as key definitions
  • easily attach supporting evidence including hyperlinks, documents and comments to support and illustrate your answers
  • quickly view questionnaire completion progress with clear color-coding scheme
  • share access to the tool within your organization to enable different users to enter data
  • control final questionnaire sign-off

What is the assessment timeline?

Companies invited to participate in the CSA for inclusion in the DJSI or other S&P ESG indices need to complete the assessment in a defined window. Once the questionnaire is submitted, the answers and supporting evidence are reviewed and assessed by S&P Global analysts. The quality control process involves a comprehensive review of the entire submission, followed by multiple layers of quality checks, including comparison with industry peers. An independent third-party audit assures the consistency and robustness of the entire process and the results. The assessment results are made available in Sept/Oct. The earliest time any result is shared is with the annual re-balancing of the Dow Jones Sustainability Indices (DJSI). This is also the case for listed companies that are not invited for DJSI inclusion or (private) companies that commissioned the CSA as a service.
