The 50 Most Promising Ideas From the Mayors Challenge

At the same time that Covid-19 exposed and magnified urban inequalities, it also prompted cities to adapt and think creatively to address some of their most pressing issues. And when Bloomberg Philanthropies challenged mayors to put forth their best ideas to bounce back from the pandemic, a record 631 cities from 99 countries answered.

On Tuesday, Bloomberg Philanthropies (the philanthropic arm of CityLab parent Bloomberg LP) announced the boldest urban innovations from 50 Champion Cities. Over the next four months, these cities will test their solutions with technical assistance from the philanthropy and its network of experts, and at the end of this year, 15 cities will each win $1 million to implement and scale their ideas.
