Institute for Sustainable Communities

What Institute for Sustainable Communities does

The Institute for Sustainable Communities (ISC) is a 501(c)(3) nonprofit organization founded in 1991 by former Vermont Governor Madeleine M. Kunin and George Hamilton, headquartered in Montpelier, Vermont with a second office in Washington, DC. Its core function is delivering community-led climate resilience and decarbonization programs through co-creation with local organizations, governments, and funders — not through a traditional software product. The portfolio spans U.S. domestic programs (Advancing Equitable Building Decarbonization in Oakland, St. Louis, and Philadelphia; Partnership for Resilient Communities; Dismantling Energy Inequity in Communities of Color; California Air Resources Board Community Support Team; Southeast Florida Regional Climate Change Compact; Thriving Communities Technical Assistance Centers) and international programs (Sustainable Supply Chain Hub in China; Mekong Sustainable Manufacturing Alliance in Cambodia, Thailand, and Vietnam; subnational climate-just transition case studies in Chinese provinces).

ISC's "technology" is best characterized as a methodology and programmatic platform rather than a software stack: co-creation frameworks, cohort-based learning (peer networking, case sharing, convenings), technical assistance for grant writing, leadership alliance convenings, and targeted grant-making. Reported outcomes include 14,642 lives touched, 179 organizations strengthened, 144 partners engaged, 55% energy reduction in AEBD-updated buildings with ~$1,400 in estimated annual savings per building, and $20M in grant writing technical assistance facilitated.

ISC's revenue model is a hybrid of foundation and government grants (U.S. EPA, USAID, Department of Energy, NSF, CBRE, and multiple private foundations) supplemented by individual donations, donor-advised funds, and stock transfers. Distribution is direct community partnership plus channel/reseller-style relationships through Leadership Alliances and cohort programs; go-to-market is community-led rather than sales-led. ISC employs 51-100 staff and is led by President Rebecca Kaduru with COO Daniel Wald, supported by a global program leadership team including China Program Director Pan Tao, Ph.D.

Scale indicators15 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• World Resources Institute (WRI): WRI is a large global research nonprofit working on climate, energy, and sustainable cities. It is comparable to ISC as a peer nonprofit operating at the intersection of climate policy, community resilience, and international program delivery, though at significantly greater scale.
• Natural Resources Defense Council (NRDC): NRDC is a major environmental advocacy and programs nonprofit working on climate, communities, and equity. It shares ISC's community-driven climate resilience, environmental justice, and U.S. policy engagement orientation at a much larger scale.
• C40 Cities Climate Leadership Group: C40 is a global network of city mayors addressing climate change. It is comparable to ISC for its city-level climate program delivery and convening role, operating at a larger scale and with a more global urban focus.
• Rocky Mountain Institute (RMI): RMI is an independent nonprofit focused on clean energy transition and building decarbonization. It overlaps with ISC's AEBD and SSCH programs (building efficiency, supply chain decarbonization) and competes for similar philanthropic and corporate climate funding.

Direct peers

• CDP (Carbon Disclosure Project): CDP runs a global disclosure system for environmental impacts including Scope 3 supply chain emissions. It directly parallels ISC's CN100 collaboration and SSCH platform focused on building supplier capacity for emissions reporting and reduction.
• Carbon Trust: Carbon Trust is an international climate consultancy and nonprofit working with businesses and governments on carbon reduction. It is comparable to ISC for its building decarbonization (AEBD) and supply chain emissions work, though more commercially oriented.
• BSR (Business for Social Responsibility): BSR is a sustainable business nonprofit that works with companies on supply chain sustainability and decarbonization. It directly overlaps with ISC's SSCH cohort-based supply chain decarbonization work, particularly with global automotive and manufacturing brands.
• ICLEI - Local Governments for Sustainability: ICLEI is a global network of local governments advancing sustainable and resilient cities. It is directly comparable to ISC's community-led climate resilience and capacity-building work with municipalities, including the Southeast Florida Regional Climate Change Compact partnership.

Emerging players

• Climate Central: Climate Central is a climate science and communications nonprofit. It shares ISC's focus on climate resilience communication and community impact, though with a more research and media orientation rather than on-the-ground program delivery.
• Urban Sustainability Directors Network (USDN): USDN is a peer network of municipal sustainability directors across U.S. and Canadian cities. It is comparable to ISC's city-level climate and resilience programs in Oakland, Philadelphia, and St. Louis, with stronger peer-learning focus.
