Climate Week Symposium

Leveraging Circularity: Science, Business, and Community

Attend the event September 20, 2022 at 3 p.m. at Barnard College's event oval

About the Event

In celebration of Climate Week NYC 2022 — the biggest global climate event of its kind — Barnard College and the Columbia Climate School are hosting a symposium on the power of circularity in building a global, equitable climate response. 

Join us, along with Manhattan Borough President Mark Levine, the Ellen MacArthur Foundation, and Circular City Week,  on Tuesday September 20, 2022 to  discuss ways to make lasting and equitable changes in three key sectors where an adoption of circular practices is necessary: science, business, and community.

Together, with NYC policy makers, leaders, and climate activists, Leveraging Circularity: Science, Business, and Community will explore the science of circularity as a critical tool for reducing global emissions and discuss powerful steps to put circularity into practice, elucidating clear and relevant steps toward meaningful action.

Circularity is all around us - let’s name it and uplift it, as a powerful tool for supporting local economies and combating climate change.
