This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.

Key takeaways

  • The foundation makes contributions only to organisations it has preselected and does not accept unsolicited requests, so a small charity should not send it a cold proposal.
  • Its stated theme is environmental causes, but its past awards went to a broad mix that includes universities, schools, churches and cultural institutions, so a fit is more likely if your work sits within that mix.
  • About 8 in 10 of its grants fall between $3,750 and $100,000, with a median of $20,000, though the largest grant was $2,000,000, so that band is typical rather than a ceiling.
  • Most of its grant dollars (85%) went to organisations it had funded before, so giving is largely repeat-led and a new applicant should expect little open competition.
  • No geographic focus is stated, so the area where you work is not a rule, although its grants have mainly been in New York, California, the District of Columbia, Massachusetts and North Carolina.
