The 2nd C40 Women4Climate Tech Challenge 2020

Deadline: 31 January 2020
Open to: all adult women, including but not limited to students, innovators, and professionals
Benefits: USD40,000 in funding to be split among the winners and used to support their experimental phase


The 2nd C40 Women4Climate Tech Challenge will select women-led innovative tech solutions for the climate with a measurable impact to experiment with them in C40 cities.

C40 cities joining the Tech Challenge commit to pilot the winning solution and contribute to the selection by participating in the expert jury panel, which will select the finalists, as well as in the mayoral and city official jury panel, which will select the winners.

Innovators, entrepreneurs, and start-ups selected to be finalists and winners will be eligible to receive financial or technical support from C40 and their partners, plus acceleration or implementation in C40 Cities. C40 support will be custom-designed for each solution, depending on the project’s level of maturity and the needs: acceleration; incubation; residence within the city; urban space for experimentation; co-design of experimentations on citizens/users.

Challenge Themes

The cities committed to pilot the winning innovative solutions are interested in the following thematic areas:

  • Adaptation and risk cities response
  • Healthy public buildings
  • Green and healthier streets

For more information on each thematic focus and the issues, they hope to solve, see the “Call for Applications” guidelines available for download from the sidebar on the right of this page.

Participating Cities

After a successful first edition in Paris and Tel Aviv-Yafo, the 2019-20 Tech Challenge has expanded to even more C40 cities.

  • Los Angeles will consider applications for ‘Healthy Public Buildings’
  • Lisbon will consider applications for ‘Healthy Public Buildings’ and ‘Green & Healthier Streets’
  • Stockholm will consider applications for ‘Green & Healthier Streets’
  • Tel Aviv-Yafo will consider applications for ‘Adaptation & Risk Cities Response’ and ‘Green & Healthier Streets’


Applicants can apply from anywhere in the world as their solutions can be piloted in any city, but please note that cities will only select one winner project to be piloted in their city.


To increase the climate impact of the winners of the Tech Challenge C40 has secured USD 40,000 in funding to be split among the winners and used to support their experimental phase. The support provided will need to comply with C40’s requirements as a 501(c)3 public charity, in that respect C40 will work with the winners to determine how to utilize the funds for the purpose of the experimentation.
