The National Employment Savings Trust (NEST) has signed up to the United Nations' Principles for Responsible Investing (UN PRI) in a bid to boost long term investing and good corporate governance.
The code aims to encourage asset owners and asset managers to factor environmental, social and governance issues into their in investment decisions.
There are currently 120 signatories to the PRI in the UK, including 26 asset owners like NEST.
Chief investment officer Mark Fawcett, pictured, said: "Signing the PRI delivers on a commitment we made earlier this year when we announced our approach to investing members' money.
"NEST believes to protect and enhance the value of investments over the long term, it must act as a responsible asset owner and market participant.
"We also believe investing responsibly enhances long-term value and reduces risk, and we have therefore embodied this view within our investment beliefs."
