Nonprofit Grant Deadlines Causes Environment Environmental grants for nonprofits This is one of the largest lists on the site. It covers watershed and water supply work, land conservation, habitat restoration, wildlife, parks, clean energy and climate projects. Many listings come from California agencies, which often keep rolling programs open with no set date, so look past the dated rows.
Land and water projects often need site control, permits or a partner agency before a funder will take the application seriously. Confirm those early. Some programs also favor projects that serve disadvantaged communities, and the notice will say how that is scored.
Scientific monitoring and ecology calls from research agencies sit in their own section below.
Pick a grant below, open the official notice, and check who can apply before anything else.
97 open listings right now. The next deadline is November 2, 2026. 29 research calls match, collapsed below.
Deadline times and time zones vary. Check the funder's page for the exact cutoff.
