The "Driving Urban Transition (DUT)" programm is an alliance co-financed by the EU with the aim of making cities climate-neutral. Drees & Sommer is part of a European consortium that is implementing the DUT project "Multigination", which is based on the principle of the "15-minute city". It aims to reduce car traffic and CO2 emissions through smaller, bottom-up urban interventions. With the help of digital tools, multiple actors will be able to actively participate in the redesign of urban spaces and the establishment of bottom-up projects. This co-design approach will enable citizens to participate in decision-making and the financing of interventions to transform specific places sustainably. Currently, the cities of Winterthur (CH), Tampere (FIN) and Istanbul (TR) are involved in the project as real-world laboratories.
