We developed an identity and campaign concept for the platform Delft Doet Duurzaam. The Municipality of Delft being the client. The aim of this platform is to inform all residents and all companies in Delft about the possibilities available and thus contribute to making the city C02 neutral by 2030. We created a communication style for Delft Doet Duurzaam that is characterized by positivity, liveliness and creativity. This is reflected in the color palette, illustration, and typography.
