Some governments have been particularly active in developing and using these risk mitigants to mobilise greater sustainable energy investment and these examples can potentially be applied to other national contexts. The Danish export credit agency EKF is a particular example of an institution that is using their guarantees to encourage institutional investor participation in sustainable energy finance. Green investment banks and other public financial institutions are also actively working to reduce risk by providing guarantees, loan loss reserves, seeding funds and acting as cornerstone investors.
