Funding pattern

What this funder pays for, at what size, and how to position adjacent work. Read from their filings, with every number checked against the record.

Where the money goes

  • Global transition to clean transportation: road, freight, aviation, maritime shipping
  • Climate, pollution, and economy policy advocacy in the US and abroad
  • Sustainable cooling, efficiency, and non-carbon pollutant reduction
  • Transition to a sustainable financial system and climate disclosure
  • Responsible carbon removal, forests, and other landscape mitigation
  • Minerals for the energy transition and communities most affected by climate change

Typical grant

Median grant is $225,000, with the middle half between $100,000 and roughly $533,000. The very large checks, $2 million to $12.7 million, go to a small set of intermediary regranters and global technical shops: Energy Foundation, ICCT, International Sustainable Energy Foundation, EDF, Rockefeller Philanthropy Advisors, Global Energy Monitor, NRDC. With 446 grants to 285 recipients over three years, repeat giving is the norm, and many recipients receive several tranches in one year tagged to different themes.

Their words

Phrases from their own grant descriptions, worth speaking back to them.

  • THE GLOBAL TRANSITION TO CLEAN TRANSPORTATION
  • TO PROTECT THE CLIMATE, REDUCE POLLUTION, AND STRENGTHEN ECONOMIES
  • TO SUPPORT RESPONSIBLE CARBON REMOVAL AND RESTORE THE CLIMATE
  • TO EXPAND ACCESS TO SUSTAINABLE COOLING AND REDUCE GREENHOUSE GAS EMISSIONS
  • THE TRANSITION TO A SUSTAINABLE FINANCIAL SYSTEM
  • TO SUPPORT COMMUNITIES MOST AFFECTED BY CLIMATE CHANGE

Positioning adjacent work

  • Name one of their exact themes, such as sustainable maritime shipping or responsible carbon removal, in your framing.
  • Ask $150,000 to $500,000 for a first engagement; multi-million awards go to established regranting intermediaries.
  • Emphasize global reach and policy influence, not local demonstration; their transportation and cooling money is international.
  • University work lands best when tied to finance, minerals, or food system analysis, as at Columbia and Maryland.

Worth knowing: Money is heavily concentrated: the top ten recipients absorb well over half the total, and DC and California organizations dominate the count. Awards are frequently split across several thematic lines within one recipient, which suggests program officers build portfolios around known partners rather than discrete one-off projects.
