This report synthesizes evidence of how grassroots movements successfully mitigate climate change, specifically in the food and energy sectors. This report was prepared by CEA Consulting with support from Gopal Dayaneni at the request of the CLIMA Fund, a funder collaborative comprised of four public foundations (Global Greengrants Fund, Grassroots International, Thousand Currents, and the Urgent Action Fund for Women’s Human Rights). CLIMA Fund members have given over 20,000 grants to grassroots groups in 168 countries over nearly four decades. The report seeks to spark inspiration and reflection within the climate funding community by 1) lifting up effective grassroots climate solutions shifting food and energy systems and 2) providing recommendations on who, how, and what to fund for durable and transformative change. We hope to strengthen understanding, recognition, and support for grassroots movements and help inspire a significant increase in funding towards innovative solutions borne and led by grassroots leaders. This report is informed by extensive desk research and conversations with funders and community members during 2022. The authors are solely responsible for the report’s content, including any errors. We are grateful to the CLIMA Fund staff and partners for the resources, perspectives, and support they shared with us. We want to specifically thank Mariam Mayet (African Centre for Biodiversity), Kentebe Ebearidor (OilWatch Africa), and Shalmali Guttal and Anusha Lall (Focus on the Global South) for serving as advisors during this process.
