S&P Global ESG Scores are assessments of companies' sustainability performance, provided by S&P Global Sustainable1. The scores are based on the Corporate Sustainability Assessment, which combines company disclosures, media and stakeholder analysis and modelling approaches. According to S&P Global, the dataset includes scores, underlying criteria, aggregates and year-over-year changes, with historical series. The data is delivered as a data product to investors, banks and other organisations, including through the S&P Global Marketplace.
S&P Global Inc. is a US company headquartered in New York. Where customer-side data is stored and which GDPR commitments apply is not stated publicly. For European organisations this is mainly a dependency on a US data source for reporting and investment decisions. S&P Global itself states that scores are an opinion as of the date of issue and may be changed.
