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

Key takeaways

  • The foundation does not accept unsolicited requests and gives by invitation only, so a cold application is unlikely to get anywhere; build a connection first and let it lead to an introduction.
  • Its focus on chemical toxicity and climate change, including clean firm energy, regenerative agriculture and carbon removal, and its funding of academic hubs and NGO partners for global advocacy, should be checked against your work before you approach it.
  • Most of its grants fall between $82,500 and $2,000,000, and half of its grants are $400,000 or less, so a modest, carefully sized request fits its typical grants.
  • It excludes proposals with indirect costs above 10%, so check your overhead rate before you prepare a budget.
  • In the filing, 86% of grant dollars went to organisations it had funded before, so a new applicant should expect a competitive, relationship-led route.

Overview

Priority Areas

The foundation focuses on the existential environmental crises of chemical toxicity and climate change. It supports clean firm energy through long-duration energy storage, improved grid transmission, geothermal and geologic hydrogen. In agriculture, it supports systemic change through regenerative agriculture and interventions to reduce agriculture's environmental footprint, and it fights toxicity primarily in agriculture and industry. Its climate work includes scalable carbon dioxide removal, research into the ramifications of tipping points and early research on interventions for climate stabilisation. It funds top-tier academic hubs and NGO partners to support global advocacy, linking cutting-edge science with real-world policy.
