This is the seventh edition of the OECD survey of large pension funds and public pension reserve funds that collects long-term investment data since it was first published in 2011. The scope of this report covers 87 public and private pension funds from 34 countries. This survey is based on a qualitative questionnaire sent directly to large pension funds and public pension reserve funds. It covers the infrastructure investments made by large pension funds and public pension reserve funds, but also their approach to environmental, social, and governance (ESG) factors. It provides detailed investment information and insights which complement the aggregated data on portfolio investments gathered by the OECD at a national level through the Global Pension Statistics and Global Insurance Statistics projects.
