Climate Smart Cities Challenge: Creating healthy, thriving and climate-neutral cities

The climate crisis is the most crucial development challenge of our time, and cities have a key role in driving the shift to low-carbon, inclusive economies.

The Climate Smart Cities Challenge open call is an opportunity for cities to participate as implementation partners in a city-based open innovation competition that will invite a global pool of technologists, businesses and investors to develop, test and scale cutting-edge solutions to reduce greenhouse gas emissions and create a better future for all.

We want you to: 

  • Tell us about your city’s aspirations to reduce or eliminate greenhouse gas emissions and create a good future for all
  • Present a problem that is specific and solvable in the near-term, meaning potential solutions could be introduced, adapted and scaled within the next five years
  • Indicate a willingness to work with a global community of problem-solvers and investors and to commit reso
