Achmea is investing €50m in the new Achmea Dutch Residential Impact Fund (ADRIF).
The money will be used to buy older, poorly insulated rental homes and to make them more sustainable. It is expected that it will mainly be housing complexes that will be taken over from business parties.
Achmea is inviting other institutional investors, such as pension funds, to participate in this fund, which can grow to a size of €1bn by 2030.
Daphne de Kluis, member of the executive board of Achmea, said: "Together, we are facing an enormous task when it comes to making existing homes in the Netherlands more sustainable. We need to work on this energetically and this requires considerable investments. With our investment, we are taking the first step."
