The City of Zero, an event dedicated to sustainability, is preparing its fourth edition, which promises to be the biggest ever. In 2024, the event attracted around 25,000 visitors, demonstrating the growing public interest in sustainability-related initiatives.
The event takes place on September 19 and 20, representing a significant change from previous editions. For the first time, the City of Zero sets up at Eduardo VII Park, in Lisbon, a reference urban space in the Portuguese capital.
This edition at Eduardo VII Park comes with greater ambition, reflecting the success of previous editions and the organizers' intention to extend the event's reach to an even larger audience.
