About Climate Change Mitigation Grants for Nonprofits

Climate change mitigation grants for nonprofits support direct environmental action—from renewable energy deployment and carbon sequestration projects to climate resilience planning and emissions reduction initiatives. 7,389 active grants fund this work, with leading support from DOC NOAA's Environmental Results Areas program alongside U.S. Mission agencies. These grants back research, on-the-ground programs, and organizational capacity building tailored to nonprofits advancing climate solutions.

Most awards range from $6,000 to $400,000 through competitive application processes, with nearly one-quarter requiring cost-sharing commitments. Filtering by support type—particularly "Program" versus "Research"—helps distinguish between grants funding direct environmental projects and those supporting scientific investigation, making it easier to identify opportunities aligned with your organization's approach.
