This paper is based on a recent survey of some of the largest pension funds across different regions, accounting for over USD 7 trillion of assets under management. We look at how much these investors have allocated to infrastructure, what is considered as infrastructure, where it fits in the total portfolio allocation, what approaches and forms of investment have been taken, what are recent trends in relation to infrastructure and asset allocation, regulation and green investment. A better understanding of these issues is necessary from a policy perspective in order to be able to attract institutional investors to the infrastructure sector.
