Sustainable Urban Transport Project (SUTP) is dedicated to enhancing transport systems in developing cities to promote sustainability and accessibility. Launched in 2003 and hosted by the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ), SUTP addresses critical urban transport challenges by disseminating information, offering policy advice, and providing training on sustainable transport practices. The project’s initiatives focus on the guiding principles of "Avoid, Shift, Improve" (A-S-I), emphasizing smart land use, public transit, and efficient vehicle use.

SUTP develops valuable resources, including the SUTP Sourcebook series and case studies, while also conducting training courses aimed at increasing organizational capacity in urban mobility planning. Collaborating with various governmental and non-governmental partners globally, SUTP fosters international dialogue on best practices in sustainable transport. Their commitment is not only to empower urban policymakers and planners but also to improve the overall quality of life for residents in densely populated cities around the world, thereby addressing pressing environmental and social issues.
