A survey by three of Europe's largest institutional investors, responsible for over €300bn ($420bn) of assets between them, found that a "strikingly low" proportion of property managers are able to offer information on their portfolios' green credentials.

Pension schemes APG, PGGM, and the Universities Superannuation Scheme, together with real estate industry bodies Epra, Inrev and Acsi, conducted the global survey, which garnered 200 responses. The survey found that only 19% of respondents were able to provide figures on the energy consumption of their portfolios. Only 16% had figures for water consumption and 14% information on carbon emissions.
