In keeping with TMF’s commitment to knowledge-sharing, the goal of the Sustainable Cities Challenge was twofold: support the development of new modes within the three host cities, while incubating innovative, workable, and impactful results for cities facing similar barriers. The company’s winning digital platform, Andemo, promotes sustainable mobility habits through innovative approaches, such as micro-incentives, which use small rewards or tokens to drive behavioral change. These demonstrations serve as examples of opportunities for validation of transportation concepts offered by the Sustainable Cities Challenge. At Challenge Works, we believe that city-led competitions are critical for developing localized solutions with the potential for global impact. Challenge Works has run over 100 challenge prizes, awarding over £370m on behalf of public, private and philanthropic funders around the world.
