The Building Decarbonization Coalition aligns critical stakeholders to transform the nation’s buildings through clean energy, using policy, research, market development, and public engagement to eliminate fossil fuels in buildings, improve public health, cut climate and air pollution, prioritize high-road jobs, and increase community resilience.
Building Decarbonization Coalition’s recent grantmaking centers on national policy, market, and workforce development for cleaner buildings. The largest grant in the file is $1.4 million to Sierra Club Foundation in 2025, and the same core funding theme appears in large awards to Rocky Mountain Institute and Rewiring America. That pattern points to a funder using multi-organization grants to support building electrification at the policy, market, and implementation levels rather than through a single program area. The coalition also backs equity-led campaigns tied to building electrification. In 2024, it gave $130,000 to The Leadership Counsel for Justice & Accountability and $60,000 to People’s Collective for Environmental Justice for that purpose, showing attention to community-based advocacy alongside broader national work. Another 2024 grant to Heat Pump Nation Inc. appears as a transfer of funds to correct account, which is a different kind of transaction from the program grants elsewhere in the file. Across the record, the foundation’s work is organized around decarbonizing buildings through policy, public engagement, market development, and workforce-related efforts.
A major share of the coalition’s giving supports national policy, market, and workforce development. In 2025, it awarded $1.2 million to Rocky Mountain Institute for that purpose, and it used the same language for a $1.2 million grant to Rewiring America. It also funds coalition-building and public engagement around clean buildings. Sierra Club Foundation received $1.4 million in 2025 for national policy, market, and workforce development, while Climate Solutions received $200,000 in 2025 under the same theme. On the equity side, the foundation backed building electrification campaigns with $130,000 to The Leadership Counsel for Justice & Accountability and $60,000 to People’s Collective for Environmental Justice in 2024. Those grants sit alongside the coalition’s broader focus on equitable implementation and environmental justice.
Typical grant size is large: the 25th percentile is $197,500, the median is $700,000, and the 75th percentile is $1,000,000. The recent record shows repeated support for the same organizations across multiple years, including Rocky Mountain Institute, Sierra Club Foundation, and Rewiring America, which suggests ongoing relationships rather than one-time awards. The foundation is a regular funder and does not fund individuals. The listed transaction types are standard grants, with one 2024 item described as a transfer of funds to correct account. No application process is shown in the data.

Grant recipients are all in the United States. Washington, DC appears as the top state by grant count, and the recipient list also includes Oakland, Boulder, Seattle, Sacramento, Calabasas, Dover, and Lewes. Delaware accounts for 17% of grants to recipients in the HQ state, which indicates some in-state giving but not a dominant share. The pattern is regional rather than national in recipient geography, even as the funding themes are national in scope.
The foundation most often funds national policy, market, and workforce development connected to building decarbonization. Recent grants use that language repeatedly, including $1.4 million to Sierra Club Foundation, $1.2 million to Rocky Mountain Institute, $1.2 million to Rewiring America, and $200,000 to Climate Solutions.

The grant-size distribution is large. The 25th percentile is $197,500, the median is $700,000, and the 75th percentile is $1,000,000. That profile suggests a preference for substantial grants rather than small awards.
Several recipients appear in multiple years. Rocky Mountain Institute, Sierra Club Foundation, and Rewiring America each received grants in both 2024 and 2025, which shows repeated support across years rather than isolated one-off giving.
No. The foundation is marked as not funding individuals, and the recent grants list is made up of organizational recipients such as Sierra Club Foundation, Rocky Mountain Institute, Rewiring America, and Climate Solutions.
