One semi-green fund that we know of in South Africa is Nedbank’s Green Savings Bonds:
The Nedbank Green Savings Bond is a fixed term investment (18, 24, 36 or 60 months), offering great rates and capital security. In addition, it is the first savings bond in South Africa to offer consumers the opportunity to contribute towards the creation and development of the Green economy. It does this by earmarking the capital raised to finance renewable energy projects, at no risk or cost to investors.
The appeal of the Nedbank Green Savings bond is somewhat dimmed by the fact that Nedbank continues to actively invest in new coal power in South Africa, though it has said it will cease doing so from 2018. For example, in October 2016, Nedbank joined a consortium of bankers financing the Thabametsi and Khanyisa coal independent power stations.
