100 solutions for climate action in cities.
Cutting greenhouse gas emissions and adapting our cities to withstand the effects of climate change is not only essential for the planet, but is
also making citizens healthier, happier, and more prosperous. This year’s Cities100 exhibits extraordinary levels of climate action undertaken by
cities of all sizes from around the world. The 100 solutions presented here add to the gathering evidence that cities are leading the fight against
climate change, and that green policies, projects, and investments are becoming central to how cities function – climate action is becoming the new normal.
These 100 solutions were selected from 175 submissions from 91 cities spread across the globe. By showcasing the 100 most ambitious, innovative, and exciting projects being implemented in cities around the world, Sustainia, C40, and Realdania hope to show what is possible and inspire further action.
