As chair of the Environment Committee in Minneapolis’s Prospect Park neighborhood, Mary Britton led a groundbreaking initiative to reduce residential carbon emissions — and the results speak for themselves. Launched in 2020, her community-driven program focused on cutting natural gas usage, a major contributor to household emissions. By 2024, Prospect Park had reduced its natural gas consumption by 11.6%, even as citywide usage remained flat or increased. That’s the equivalent of taking 154 gas-powered cars off the road — for good.
Mary’s work has become a model for neighborhood-scale climate action, proving that grassroots leadership can drive measurable, scalable change. A financial data analyst by profession, she brings analytical rigor and a passion for sustainability to everything she does — including her personal mission to make her own home carbon neutral.
She lives in Prospect Park with her two dogs and continues to champion local solutions to the global climate crisis.
