Cities and Climate Solutions | Waste

Webinar | December 20, 2023 | 6:30 a.m. New York | 12:30 p.m. Paris – Montpellier | 1:30 p.m. Quelimane | 5:00 p.m. Maharashtra

Waste management represents a major challenge to the sustainable development and health of urban communities worldwide. Long considered simply something to dispose of, waste is increasingly becoming a cornerstone of ambitious urban sustainability strategies. According to the principles of circularity, waste management makes it possible to reduce air, water, and soil pollution, foster equity and economic growth, strengthen urban-rural bonds, and improve public health.

Through the accounts of Quelimane in Mozambique, Montpellier in France, and the State of Maharashtra in India, the Cities and Climate Solutions | Waste webinar will explore and discuss the challenges and opportunities of urban waste management, drawing valuable insights for cities around the world.

The Cities and Climate Solutions webinar series is co-organized by the City Diplomacy Lab and Columbia Global Centers | Paris. This webinar is co-sponsored by the Commonwealth Local Government Forum (CLGF).

Overview of the Cities and Climate Solutions series

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. This series, launched in Spring 2023 with events on food and water, 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 from three cities 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.
