ICLEI enables mobility planning authorities across Europe to embrace sustainable urban mobility plans (SUMP) as the European-wide strategic planning approach, especially in countries where the take-up is low and the negative effects of transport are severe. The project also improves urban transport efficiency while effectively mitigating the negative effects of transport and enhancing the attractiveness of Europe’s urban centers through a strategic planning approach based on integration, participation and evaluation principles, one that broadly implements sustainable urban mobility policies and measures. The project analyzes and verifies specific adoption needs for SUMPs in European local authorities in order to identify the most effective tools for SUMP development and actively support their adoption in various types of cities.
