MotivationLab, in collaboration with Peter van Welsem, studied the relationship between litter and peoples’ experience of an area. The study was commissioned by NederlandSchoon, Gemeente Schoon and NVRD. We examined in various municipalities at which degree of cleanliness (according to the CROW image method) residents indicate that they are satisfied with the outdoor area and when they are dissatisfied. Wondering where these so-called (dis) satisfier limits lie? The report can be read on the “Kenniswijzer zwerfafval”. It also explains how showing involvement of entrepreneurs and citizens (via posters) appears to have a positive effect on the experience.
