This study developed a spatial multi-criteria screening tool in Barcelona, Spain, to prioritize green roof locations and designs for optimal ecosystem service provision. Fifteen spatial indicators and five green roof designs were analyzed and weighted by local experts. The assessment found high demand for green roof ecosystem services across Barcelona, especially in dense residential and industrial areas, with habitat, pollination, and thermal regulation being most needed, while runoff control and food production were least demanded. Naturalized roofs offered the highest potential for 87.5% of rooftop area.
