Corporate Sustainability Assessment

What is the CSA?

The S&P Global Corporate Sustainability Assessment (CSA) leads the field in helping companies make the link between sustainability and their business strategies.

Covering over 13,000 companies globally, the CSA is an annual evaluation of a company’s sustainability practices. It enables you to benchmark your company’s performance on a wide range of industry-specific economic, environmental, and social criteria that are relevant to the growing number of sustainability-focused investors and are expected to be financially relevant to your corporate success.

Leverage the unique expertise and the proprietary methodology underlying the world’s most renowned sustainability indices.

Our Approach

In 2023, over 3,500 companies actively participated in the CSA – up from 3,000 in 2022. The CSA compares companies across 62 industries via industry-specific questionnaires that assess, on average, 23 sustainability topics in 110 questions. Based on their performance, companies receive scores ranging from 0 to 100 and percentile rankings for financially relevant sustainability criteria.

Participating companies represent half of global market capitalization (relative to the S&P Global Market Index). Participants represent half of the companies in the S&P Global LargeMid Cap index, 60% of companies in the S&P 500 index, and 63% of companies in the S&P Global 1200 index. Over the past 25 years, as the CSA has grown into a leading corporate sustainability database, it has also attracted the interest of capital market stakeholders. Since becoming available on the S&P Global Capital IQ Pro platform three years ago, ESG Scores calculated from the CSA are used by clients across 49 countries overseeing $38.4 trillion in assets under management (AUM) to benchmark corporate performance, manage investment portfolios, allocate financial capital, build engagement strategy, and much more.

To ensure the quality and objectivity of the CSA, S&P Global voluntarily appoints an independent third party, Deloitte, to conduct an external audit of the assessment process each year.
