Hundreds of cities across the United States, Europe and Latin America have applied to the Mayors Challenge, advancing bold thinking and experimentation for global solutions. The program touches millions of lives –from the citizens who are affected by bold new innovations, to the hundreds of city leaders who use new strategies and tools to better meet the needs of their residents.

Fifteen ideas from the U.S., European and Latin American cities, showing exceptional vision and potential for deep and broad impact, were selected to receive funding in support. Bloomberg Philanthropies is currently working with these cities to help implement their ideas and support their spread to cities around the world.
