How they approach the work

Named approaches extracted from this org’s sources. Where others share an approach, follow it to see the full set of orgs running it.

  • Capacity Building for Community-Based Clean Energy Lending and Technical Assistance
    methodology: capacity_building_for_clean_energy
    By strengthening the institutional capacity of CDFIs and nonprofit technical assistance providers, we increase access to clean energy financing and implementation support in underserved communities because organizational readiness enables effective deployment of resources and trust-based outreach.
  • Community-Integrated Clean Energy Transition
    methodology: community-driven clean energy transition
    By integrating clean energy initiatives with community development, we ensure equitable and inclusive sustainability outcomes because community ownership and participation increase adoption, durability, and social co-benefits.
  • Data- and Portfolio-Driven Decision Making for Decarbonization
    methodology: data-driven decision making
    By applying data analytics at the portfolio level, we optimize decarbonization investments because identifying patterns in energy use, equipment age, and capital timelines enables cost-effective, coordinated upgrades aligned with existing financial cycles.
  • Equitable Access to Federal Decarbonization Funding
    methodology: equitable funding deployment
    By connecting technical assistance providers with community lenders, we ensure equitable deployment of federal decarbonization funds because bridging implementation and financing networks lowers barriers for disadvantaged communities to access and utilize complex funding streams.
  • Stakeholder-Engaged Decarbonization Planning
    methodology: stakeholder-engaged decarbonization planning
    By involving residents, owners, and operations staff in collaborative decision-making, we produce more durable and context-appropriate decarbonization outcomes because inclusive processes yield higher buy-in and operationally feasible solutions.
