A group of Canadian pension plan investment managers is calling on companies to standardize their environmental, social, and governance disclosure to help them in their investment decision-making and better assess and manage their risks.

The eight fund managers together manage a total of about $1.6 trillion in assets.

They say they are committed to creating more sustainable and inclusive growth by integrating environmental, social and governance factors into their strategies and investment decisions.

The group says it is an integral part of their duty to contributors and beneficiaries and will unlock opportunities and mitigate risks.

But the investment managers say they require transparency from companies.

The letter is signed by the chief executives of AIberta Investment Management Corp., B.C. Investment Management Corp., the Caisse de depot et placement du Quebec, the Canada Pension Plan Investment Board, the Healthcare of Ontario Pension Plan, the Ontario Municipal Employees Retirement System, Ontario Teachers’ Pension Plan and the Public Sector Pension Investment Board.
