At the outset of any new investment, APG ensures that ESG policies and behaviours are assessed and reviewed. The managers of all new investments under consideration are asked to fill out the APG Due Diligence Questionnaire, which includes detailed ESG questions. These results, in combination with additional information requests and interviews, are then assessed in detail by the GRIG (Global Responsible Investment & Governance) team specialist and form the basis for their mandatory and independent signoffs that are presented to the global Committee for Investment Proposals (CIP) prior to investment. Participation in the GRESB Infrastructure survey is mandatory for all new investments in this asset class. In 2017, 19 managers and 34 assets responded to the survey.
