GREEN project main innovation lays in the development of new tools and services for the assessment of green infrastructures multiple benefits. In order to reach this aim the project will collect and critically review the evidence that enables a sound and thorough assessment and monitoring of the function of green infrastructures. This process also needs an in depth analysis of current and potential governance and business models to foster the realization of green solution and their market replication. For this specific purpose the GREEN case study will develop methodologies for the upscale and large-scale deployment of green infrastructures in Europe. As to support this effort the partners it is vital to develop criteria and instruments for the monitoring and evaluation of green infrastructures functions in the reduction of risk. This will entail the construction of a series of indicators and measures that will support a robust assessment of the performance of the advocated solutions over the long term.
