Can individuals save the planet from the multiple sustainability problems which we are facing? Can ICT create a higher level of consciousness about the state of the environment, and about the role that local individual actions can play in the global society, at the level of lifestyles or democratic participation? During this dialogue, the role of online platforms for collective awareness and action will be explored. Platforms based on the connecting power of online social networks and on the knowledge coming from collective co-production, combined with the Internet of Things. This one-day dialogue, part of the Paradiso international conference, aims to contribute to identifying related multidisciplinary research priorities for the last Call of FP7 and for FP8.
