In the face of the climate crisis, cities across the world are emerging as integral problem-solvers in the development of an effective, multi-layered response. The Cities and Climate Solutions series, launched in Spring 2023 with events on water and food, aims to bring together the representatives of cities that have implemented some of the most impactful and sustainable actions.

This second season of the webinar series kicked off in November 2023 and covers the topics of air, energy, and waste. Each webinar will see the participation of representatives of three municipalities and will be moderated by a representative from Columbia University. In order to encourage geographic representativeness, each webinar will host city representatives from different regions and countries.

This series celebrates the leadership of cities and provides inspiration for the thousands of cities and local governments around the world committed to shaping the global response to climate change.
