From the High Level Panel final report:
"International financial institutions can compensate for the market’s failures to supply long-term finance for sustainable projects in low- and middle-income countries, but they need to be more innovative, flexible and nimble in the way they operate. The Panel noted the huge potential to use public money to catalyse and scale up private financing for sustainable development. For example, only 2 per cent of the $5 trillion in sovereign wealth fund assets has so far been invested in sustainable development projects."
