The Bernard and Anne Spitzer Charitable Trust made a single, very large grant focused squarely on environmental protection, indicating a strategic, high-impact approach. Rather than distributing funds across many organizations or causes, the trust appears to concentrate its resources on major environmental initiatives that align with climate and conservation priorities. The size and recipient suggest a preference for established environmental entities or trusts positioned to deploy substantial funding for systemic impact.
A $10 million grant to the Jeremy Hannelore Grantham Envir Tru for environmental protection sets the tone for the Bernard and Anne Spitzer Charitable Trust’s recent giving. The trust directs large awards toward climate and environmental work, including repeated support for Clean Air Task Force, Climateworks Foundation, and other intermediaries built to move policy, research, and implementation at scale. Its recent grants also show that environmental giving is not isolated from other priorities: the trust has backed state climate policy, clean industrial technology, clean grid work, and carbon dioxide removal through substantial grants in the seven-figure range. The trust also funds institutions tied to the Spitzer family name, including the Anne & Bernard Spitzer Endowment Fund at the American Museum of Natural History and the Anne and Bernard Spitzer School of Architecture at The 21st Century Fnd City College N. Alongside those named commitments, it has supported civic, legal, and community organizations such as New Venture Fund, Rockefeller Philanthropy Advisors, and Educational Alliance Inc. The pattern suggests a funder that combines major environmental policy investments with selected institutional and community support.
Environmental policy is the clearest through line in the trust’s giving. It supported Clean Air Task Force with $2.75 million in 2025 for the general purpose clean industrial technology campaign and state climate policy, then repeated the organization with a $1.5 million grant in 2023 for clean energy standards. The trust also backed carbon dioxide removal through Climateworks Foundation, giving $1.857 million in 2023 and $1.25 million in 2024 for the Carbon Dioxide Removal Fund. Grid and clean-energy work appears through Multiplier, which received $1.5 million in both 2024 and 2025 for the Clean Grid Initiative, and Third Way Institute, which received $1 million in 2024 for Pathways to Accelerating Clean Energy. Beyond climate, the trust funded state infrastructure and election-related work through Neo Philanthropy and New Venture Fund, showing interest in policy-adjacent grantmaking channels.
The typical grant size is $10,000 at the 25th percentile, $35,500 at the median, and $400,000 at the 75th percentile, which points to a mix of smaller awards and large institutional grants. In the recent grants list, several organizations appear across multiple years, including Clean Air Task Force, Climateworks Foundation, Multiplier, Neo Philanthropy, New Venture Fund, Rockefeller Philanthropy Advisors, Third Way Institute, and the American Museum of Natural History. That repeat pattern suggests ongoing relationships rather than one-off awards. The trust is a regular funder and does not make program-related investments. It also funds individuals.
