Carolyn-Claire Bridges

Intersectional Environmental Activist
Carolyn-Claire Bridges is a 19-year-old Intersectional Environmental Activist - a movement popularized by Leah Thomas. Intersectional environmentalism is an understanding that social justice and environmental justice are bound together - it is a fight for the protection of both people and the planet. Residing in Tampa, FL, she actively advocates for sustainable practices to be implemented on both individual and corporate levels in addition to fighting for social justices. Recently, Carolyn had the privilege to work with an amazing group in the Bay Area on drafting a declaration of climate emergency for Tampa Bay. In her talk, she hopes to spotlight the origin of the majority of annual carbon dioxide emissions, outline steps that can be taken in everyday life to lower our carbon footprint, and propose other sustainable solutions with the hope of creating a promising future for everyone.
