City challenge: one million dollars for innovative ideas post COVID-19

11 January 2021

Bloomberg Philanthropies has launched an innovation competition for cities, looking for the most ambitious ideas developed in response to COVID-19. The Mayors Challenge 2021 will select 50 finalists that represent the world’s leading urban innovations to emerge from the pandemic. Fifteen grand-prize winners will receive $1 million each and multi-year support to implement and spread their breakthrough ideas on a global scale. Eurocities is a partner for the Mayors Challenge.

Who is the programme for?

The 2021 Global Mayors Challenge is open to all cities with populations greater than 100,000 residents. Applications must be submitted no later than 21 March 2021. Cities can register and apply here

What makes a great idea?

The Mayors Challenge is looking for the 50 leading urban innovations that were imagined or launched in the wake of the COVID-19 pandemic. These ideas can be in any stage of implementation, but must have the potential for meaningful impact, and the ability to spread to other cities.

What can cities win?

This year’s Global Mayors Challenge, the fifth round of the competition, will give 50 champion cities access to world-renowned experts in innovation and data to help them improve upon their idea. Fifteen grand prize winners will then receive $1 million each to begin the implementation of their ideas.
