    Short description of measure

    Problem to be solved: Overheating

    Goal, potential objective: Reduce urban heat island effect by greening the rails of trams

    Developmental steps: Agreement with relevant transportation companies, greening the relevant rail areas

    Instruments, implementation mechanism: New rails: legislation; old rail stock: voluntary agreement; subsidies

    Area of implementation: Urban

    Responsibilities: Local administration

    Time horizon: Medium term

    Economic aspects: The costs to build green rails are only slightly higher than to build normal rails. On the other hand, the maintenance is cheaper in the long run because of better construction.To minimize operating costs, irrigation and chemistry should be prevented.

    Side effects:

    Bridge to mitigation: Reduces urban heat island effect and thus reduces the need for cooling houses in summertime
