Information available to urban planners – such as applicable legal frameworks and relevant policies – are useful to citizens, providing them with a better insight into the planning process and local government decision making. ICLEI is exploring how to use social media and other ICT solutions for better public participation and urban co-creation, and develop new applications together with 3 major European cities. ICLEI will give citizens access to data about their city in an easy to understand way, enabling them to better support the decision-making process.
