Moody’s described the acquisition as aligning with its “ongoing global commitment to promoting transparent standards for evaluating ESG risks”.
“Locally, the investment strengthens Moody’s presence and engagement in China and its financial markets, with a focus on supporting long-term, sustainable growth and contributing to the healthy development of ESG markets.”
The ratings agency said the deal complements its recent acquisitions of Vigeo Eiris, a global provider of ESG research, data and assessments; and Four Twenty Seven, a climate data and risk analysis firm.

STGF also founded the China Social Investment Forum.
