Final Thoughts
When approaching these funders, remember to emphasize how your work aligns with their specific environmental priorities. Many of these foundations are looking for innovative, systemic approaches rather than standard service delivery. They want to see how your organization is building bridges, fostering collaboration, and creating lasting environmental change.
Carefully review each funder's guidelines and focus areas before applying. While some accept unsolicited proposals on a rolling basis, others have specific deadlines or require an invitation. Building relationships with program officers can be invaluable for foundations that don't accept unsolicited requests.
Note: Grant guidelines and deadlines are subject to change, so always verify current information on the funder's website before applying.
