The City of Turku has created an innovative and inclusive movable bicycle garage that has been promoted alongside with urban sustainable mobility in an unconventional way, by arranging a participatory art competition. The competition brought together the city’s different departments, local artists, media, and the citizens of City of Turku to discuss and think about the themes surrounding sustainable and electric mobility in a multidisciplinary manner. In this paper we will cover the process of arranging an art competition as a way of marketing and as a participatory tool, using the City of Turku’s work as a case example. The paper will analyse the difference between the concepts of art and advertising as a way of communicating and affecting people. We will also examine how art can be used to engage people’s emotions to affect their behaviour and help them make better and more sustainable mobility choices in their everyday lives.
