The Dutch City Deal, “A smart city, that’s how you do it,” is an initiative launched by the Dutch Ministry of Interior and Kingdom Relations and the G40 network in 2020. It represents 58 stakeholders working on the broader area of smart cities in the Netherlands, which includes the topic of citizen measurement initiatives. Twelve working groups of the Dutch City Deal are collaborating to co-design optimal future-proof solutions by using digitisation and technology. These include the working group “Lokaal meten: betrekken en activeren burgers” which focuses on engagementaspects of citizen science initiatives and “Lokaal meten: Vergelijken van uitkomsten tussen” which focuses on comparability of data produced by citizen science initiatives. The Future City Foundation has been coordinating the efforts towards developing different outputs as well as cross-learning opportunities in online and offline meetings. 56 Visit the project website
