Bloomberg ESG Data is Bloomberg's collection of environmental, social and governance data and ESG scores for investors and financial professionals. According to Bloomberg, the scores are based on publicly available, company-disclosed data rather than subjective analyst opinion. The data is available through the Bloomberg Terminal, including the ESGD function, or across an organisation through Bloomberg Data License. Bloomberg also offers MSCI ESG Ratings on the Terminal.
The provider is Bloomberg L.P., a privately held company headquartered in New York, with the majority of the shares held by a private owner in the same jurisdiction, so there is no foreign parent. No hosting location or GDPR statement is publicly stated, so US processing is the working assumption. The product is a licensed data and terminal service, not self-hostable software. For a European organisation this means dependence on a US data supplier, with the CLOUD Act relevant wherever portfolio or reporting data is linked to the service.
