Four female innovators announced as winners of C40 Women4Climate Tech Challenge 2020

Their winning projects will be brought to life in cities involved in this challenge, which is sponsored by the VELUX Group.

The winners of C40’s second Women4Climate Tech Challenge 2020, their innovations, and where they will be implemented are:

  • Lorena Gordillo Dagallier from Cambridge (UK), whose innovation called “Open-Seneca”, a mobile air quality sensor network plus educational workshops, will be implemented in Stockholm and Lisbon.
  • Anai Green from Tel Aviv-Yafo, whose innovation called “Lumiweave”, an innovative fabric, which offers a shade function at the same time as permitting light, will be implemented in Tel Aviv-Yafo.
  • Meiling Gao and Vivian Bi from California, whose innovation called “Clarity”, a smart, indoor-outdoor low-cost air monitoring system that provides real-time air quality data, will be implemented in Los Angeles.

These projects will share $50,000 in funding to support their experimental phases in each city.

Congratulations to these women for their innovative solutions that will now gain momentum to come to life in cities around the world. This challenge really emphasises that women-led solutions for sustainable development and climate action are important for shaping the cities and communities that we would like to live in.

Women4Climate Tech Challenge 2020 – a joint initiative

The Women4Climate Tech Challenge 2020 is a joint initiative from the VELUX Group and C40 Cities, in collaboration with the four C40 host cities Lisbon, Stockholm, Los Angeles and Tel Aviv-Yafo. The Challenge aims to support and promote diversity and inclusion in technology, innovation, and the built environment sectors.
