The Green Hackathon in Szeged, held on June 21, 2024, at Agora Szeged, was a tremendous success. Organized by the Municipality of Szeged and Energiaklub as part of the GreenScape CE project, the event brought together citizens and local residents to brainstorm and innovate on some of today’s most pressing environmental challenges. Topics included rainwater retention, biodiversity enhancement, urban heat island management, and public engagement. Participants collaborated to explore new green solutions critical for local adaptation to climate change. A big thank you to all who contributed their enthusiasm and innovative ideas. Together, we can continue working towards a greener and more sustainable Szeged.
