Mission

FIGHTING THE ENVIRONMENTAL CRISIS BY RAISING AWARENESS OF THE CURRENT ENVIRONMENTAL CRISIS; PROTECTING BIODIVERSITY AND CLIMATE RESILIENCE THROUGH LAND PRESERVATION AND RESTORATION; DEFENDING AND SUPPORTING DEMOCRACY AND ENVIRONMENTAL ACTIVISM; LOBBYING AND OTHER ADVOCACY IN SUPPORT OF THESE ISSUES; AND MAKING GRANTS TO OTHER NONPROFIT ORGANIZATIONS.

Each tax year counts once: when a return was amended, only the latest return for that period is used below (superseded returns stay listed, greyed, under Finances).

People paid by the organization

1 person paid across every filing: current people first, then by total pay from this organization. Organizations counts every nonprofit each person appears on.

Who the money went to

Grants this organization reported paying: Schedule I Part II of the Form 990, or the grants-paid list on the 990-PF. Open a year for every recipient. Recipients link to their own page when the grant names an EIN we have (990-PF grants list no EIN, so those link only on an exact, unique name and state). Grants to individuals are counted; their names are not shown.

2024 · 8 grants to organizations · $2.7M
2023 · 2 grants to organizations · $3.2M
2022 · 4 grants to organizations · $340K

Negative amounts are returned or refunded grants; they are listed last and left out of the totals of grants paid.

Who gave

Contributor names are not public for this form type.

Public charities filing Form 990 or 990-EZ report large donors on Schedule B, but the IRS withholds their names and addresses from public copies. Private foundations (990-PF) are different: their contributors are public.

Finances

Newest first. Each filing: its name on one row, its figures on the row beneath. Greyed filings are superseded by a later return for the same period and are left out everywhere else on this page.

Where the money went

Every expense line on each return, biggest first: Form 990 Part IX (with its program, management and fundraising columns), 990-EZ Part I, or 990-PF Part I. Event marks lines the organization itself describes as events. “Events” in each summary adds those lines, conferences and meetings, and the direct costs of fundraising events. Unusual is not the same as improper. Many of these patterns have ordinary explanations. Check the filing.
