i4r has no fundamental minimum requirements w.r.t. the size of the project and project status, or w.r.t other typical investment criteria. Always it is the individual quality of the project which is decisive. Long-term engagement, an attractive return or possibilities of business growth do have a connection with renewable energy and the idea of sustainability, even if the number and availability of projects allowing this synthesis were to be small.

i4r has the goal of identifying projects offering this synthesis. Once a positive investment decision has been taken, then i4r generally pursues a long-term investment policy.
