On 25 and 26 October 2018, the Fondazione per l'innovazione Urbana, in collaboration with the City of Bologna, organized the third edition of Climathon in Bologna, the worldwide 24-hour marathon promoted annually by Climate-Kic to develop innovative proposals to combat the impacts of climate change in urban contexts.

The challenge posed in this edition — 24 participants, including developers, communications experts, geographers, students, and enthusiasts with various training — was to design the interactive section of a mobile app dedicated to air quality in Bologna, which had already been partially developed under the Laboratorio Aria.
