The concept of the European City of Science intersects with public marketing in multiple dimensions. This initiative highlights the presence and essential role of scientific institutions within the designated city and emphasizes social initiatives that leverage science to address everyday challenges. The XXIV International Congress on Public and Non-Profit Marketing held in Katowice, Poland focused primarily on the region of Metropolis GZM, which has been undergoing socioeconomic and technological transformation since the 1990s.

It covers marketing perspectives on topics such as health promotion, sustainable development, citizen-friendly public spaces, and citizen science, to name a few.
