Smart City Expo World Congress in Barcelona is a unique event bringing together organizations, institutions and startups operating in the area of urban development with an emphasis on sustainability and new technologies.

The Górnośląsko-Zagłębiowska Metropolia (GZM Metropolis) wanted to emphasize the importance of plants in the urban tissue, which is why the stand was a green island at the fair. Throughout the event, it was very popular among guests who sat down to relax and learn something about the host. The stand received the "Most Sustainable Exhibitor" award.
