The Pension Protection Fund has revised its Responsible Investment framework to improve the way in which it monitors external managers.
Executive director of financial risk Martin Clarke said: 'Over the last three years we have seen a vast improvement in the way that our external managers are adopting Responsible Investment.
'Thirty per cent of our managers are now rated higher on their commitment to Responsible Investment than when we first hired them.'
Speaking yesterday, Clarke said the PPF's investment portfolio expected is to rise to £22bn in the next three years, and so 'our commitment to responsible and sustainable ownership becomes even more important'.
The revised framework would help PPF to better define its voting policies, ensure greater accountability and improve its monitoring of external managers, with closer scrutiny and oversight of the stewardship activities conducted on its behalf.
