Allen Family Philanthropies Call to Non-Profit Organizations | Accelerating Natural Climate Solutions (NCS) in the US

NCS are some of the few shovel-ready climate change mitigation technologies available today, and they have broad public support. To be effective, NCS must be implemented rapidly and rigorously, but there are numerous technical, social, economic, and other barriers to implementation. Evidence shows that across all NCS pathways and barriers, science and technology solutions can help overcome barriers and accelerate implementation.

The foundation is particularly interested in U.S.-based projects consisting of diverse teams of scientists, practitioners, and key stakeholders (e.g., community members, landowners, state land managers, etc.) to co-develop, test, and deploy science and technology solutions addressing barriers to NCS implementation. A total of $10M will be available to fund 6-7 projects (each lasting up to 3 years in duration) via this Request for Proposals (RFP).
