To help mark its 10-year anniversary, the PRI in London commissioned Steward Redqueen to carry out an independent evaluation of its impact. The main research question was what has the PRI (Principles for Responsible Investment) contributed to mainstreaming responsible investment. This independent evaluation report, which was called “From Principles to Performance” was published on April 15th at a PRI anniversary event in New York.
