Sovereign wealth funds (SWFs), government-owned investment vehicles, have become substantial players in the global financial architecture. As such, they are considered a potential source of financing for sustainable development. For the time being, however, sustainable development is not a theme that is represented prominently, if at all, in SWFs’ investment policies. That can only change if the sustainable development agenda’s cause is framed in the policy context in which SWFs operate. Three possible options come to mind: The asset owners of SWFs, that is governments, benefit from including sustainable development as an investment theme in SWFs’ investment mandates. Sustainable development could be positioned as an instrument to reduce risks to investments in less-developed jurisdictions. Sustainable development-informed investments could be tailored to meet SWFs’ financial performance objectives.
