Citigroup Inc. will collaborate with Truvalue Labs to analyze companies' corporate environmental, social and governance behavior, the bank said Wednesday.

In the partnership, Citi will incorporate Truvalue's ESG assessments into its company research. Truvalue uses artificial intelligence to mine data sources and determine companies' ESG behavior independent of their self-reporting, Citi said.

Truvalue's data cover more than 19,000 public and private companies, according to Citi.
