Washington, D.C. · Grantmakers
Imperigo has identified 930 funders that made 7,688 grants totaling $4.3B to 292 environment & conservation organizations in Washington, D.C., with a median grant of $49K. Every figure below is drawn from IRS Form 990 filings through 2025.
Funders are ordered by how much of their overall giving goes to environment & conservation work in Washington, D.C., not by dollar totals alone — a foundation that concentrates its giving here is usually a better prospect than a larger one for which this is a rounding error. 18 of the funders counted here are donor-advised fund sponsors, which grant on behalf of individual donors and accept no applications; they are marked and ranked last.
A grant appears here when a funder reported it on its IRS Form 990 and the recipient organization is classified under the NTEE group covering environment & conservation work, with an address in Washington, D.C.. Grants are counted from the 2025 filing year backward.
Some 990 grant schedules list a recipient by name and address without an EIN, and those grants cannot be matched to a classification — so the totals above represent identifiable environment & conservation funding in Washington, D.C., not every dollar that reached the sector. Figures are a floor, not a ceiling.
