Deadline: 1 October 2026

The Climate U 2026 Hackathon is the closing event of the Climate U programme, organised by the LIDERA Community in partnership with the Calouste Gulbenkian Foundation. On 10 October, young people from across the country will gather in Lisbon to develop ideas, create projects and find solutions to challenges linked to sustainability and climate action. The Hackathon is open to young people aged between 15 and 35, and participants may enter with an idea at an early stage or with a project that has already been developed. Registrants will work in teams, receive guidance from mentors and present their proposal to a panel of judges.
