Mayors Challenge: Our 50 Champion Cities

Bloomberg Philanthropies has selected the 50 Champion Cities that are advancing in the 2021 Global Mayors Challenge. These cities—which represent the 50 most innovative urban solutions to emerge in the wake of COVID-19—are now competing to become one of 15 Grand Prize winners, each of which will receive $1 million to implement and spread their breakthrough idea.

Welcome to the Bloomberg Cities Network

"Local governments play a critical role in tackling the biggest challenges we face, from combating the COVID-19 pandemic to reducing carbon emissions. At Bloomberg Philanthropies, we’re working hard to help cities develop effective strategies – and to spread them around the world. The Bloomberg Cities Network, which we developed in partnership with Johns Hopkins, is a place for innovators in government to come together and hear about what’s working, share lessons, and access resources. We hope you will take full advantage of it – and that it will allow you to expand your ambitions and accelerate your work."
