    About Hampshire Foundation

    Hampshire Foundation Inc. concentrates its giving on environmental and climate-focused advocacy, legal capacity, and community resilience—prioritizing organizations that drive policy change, strategic litigation, and on-the-ground rights and tenure work. Grants are large and targeted, often supporting intermediary/advisory groups and networks that scale climate mitigation, air quality improvements, sustainable city initiatives, and land/tenure security. The foundation favors organizations that blend policy advocacy with technical or legal expertise rather than small grassroots service providers.

    About Hampshire Foundation

    Hampshire Foundation Inc. uses large program-support grants to back climate, nature, and rights-based organizations that work through policy, litigation, and intermediary funding structures. Its recent funding includes $2,000,000 to Windward Fund for program support, $1,060,000 to Clean Air Task Force, and $1,005,762 to ClientEarth, showing a pattern of high-value grants to organizations with legal, advocacy, and campaign capacity. The foundation’s giving reaches beyond one issue area, but the common thread is work that links environmental protection with resilience, livelihoods, and governance. Recent awards also include Tenure Facility for land tenure security, Namati for legal empowerment, and Sustainable Ct for climate resilience in Connecticut. It also supports grantmaking and advisory platforms such as Rockefeller Philanthropy Advisors and Meliore Foundation, indicating use of intermediaries alongside direct nonprofit grants. Grant purposes in the recent record are mostly program support, with some operational support. The mix suggests Hampshire Foundation Inc. funds established organizations that can absorb significant unrestricted or semi-restricted awards and deploy them in advocacy, legal strategy, and field programs at scale.

    What Hampshire Foundation Funds

    Climate policy advocacy is a core theme. The foundation gave $2,000,000 to Windward Fund for program support and $1,000,000 in the prior year, pointing to repeated support for intermediary climate advocacy work. It also awarded $1,060,000 to Clean Air Task Force for program support, alongside $560,000 in 2024, which links the funder to clean air and decarbonization advocacy. Legal and tenure work is another clear strand. Hampshire Foundation Inc. granted $1,005,762 to ClientEarth for program support and $665,000 to Tenure Facility, with an earlier $250,000 award to Tenure Facility in 2024. It also gave $600,000 to Namati Inc for program support, aligning with legal empowerment and rights-based environmental governance. The portfolio also includes resilience and sustainable livelihoods. Examples include $725,480 to Sustainable Ct for program support, $531,290 to Spark Microgrants, and $489,676 to Tree Aid. Those grants show attention to community resilience, local support systems, and nature-linked livelihoods.

    How Hampshire Foundation Gives

    Typical awards are substantial: the p25 grant is $48,750, the median is $100,000, and the p75 is $200,000. The recent list shows a much higher upper tail, with multiple six- and seven-figure grants. Hampshire Foundation Inc. is a regular funder and a program-related investor, which fits the presence of recurring program support and some operational support awards. Several recipients appear across multiple years, including Windward Fund, Clean Air Task Force, Sustainable Ct, and Tenure Facility, showing repeat support rather than one-off giving.
