During the day of May 23 a guerrilla marketing action employs stencils, chalk painting, and creative signage to spread awareness in the Borgo Valdocco area. The initiative, promoted by the European project Conexus, aims to raise awareness among citizens and festival participants about the positive effects of nature-based solutions. Interventions such as widening sidewalks, introducing draining flower beds and new trees counteract the effects of climate change in the city and provide a safer and more welcoming environment. 

Guerrilla marketing initiatives can be seen for free between via Salerno and corso Ciriè, via Biella and via Pesaro, via San Pietro in Vincoli and strada del Fortino.
