National Employment Savings Trust, London, hired RepRisk and Sustainalytics to provide environmental, social and governance risk screening tools, a spokesman said.
The £6 billion ($7.6 billion) U.K. defined contribution plan selected the data providers to supply databases across all of NEST's portfolios.
RepRisk offers artificial intelligence technology to filter through news stories and actions by investee companies in real time, providing an ESG score. Sustainalytics will help NEST monitor exclusion policies across its funds.
The databases will be fully integrated into NEST's investment decision process, including asset classes such as commodities and private credit.
"It's important we're constantly reviewing how we scrutinize the companies we invest in for new ways to keep our finger on the pulse," said Diandra Soobiah, NEST's head of responsible investment, in a news release. "These new databases will present the latest available information about our investments, helping us make more informed decisions as to whether they meet our expectations."
