building costs of green roofs are currently too expensive in Finnalnd. The cost-benefit calculations hint that with a higher rate of implementation and realization of public benefits, the green roofs would be a good investment. However, because the private benefits are not high enough to justify a green roof installation for a private decision maker, the rate of implementation can be expected to stay low without corrective policy instruments. Policy instruments could include supportive policies that add incentives for private decision makers to install green roofs, such as storm-water fee reductions (already a reality in Vaasa) or real estate tax abatements.
