BlackRock Future Builders

BlackRock Future Builders is a $100 million philanthropic initiative funded by The BlackRock Foundation to expand economic opportunity and power the next generation of America’s skilled trades workers. Through this Request for Proposals (RFP) process, The Foundation seeks to support U.S. nonprofit organizations (i.e., registered 501(c)3 organizations) delivering or supporting high‑quality skilled trades training.

This competitive grant opportunity operates in parallel to other BlackRock Future Builders partnerships and is intended to surface additional, regionally grounded solutions across the skilled trades ecosystem. Organizations may propose direct worker training programs or capacity‑building efforts that enable systems to function more effectively and at greater scale. This first round RFP will be administered by Jobs for the Future (JFF), a national nonprofit that transforms U.S. education and workforce systems.

Focus Areas and Solutions

Applicants may propose worker training or capacity‑building solutions aligned to skilled trades workforce development.

• Worker training interventions may include direct service proposals such as pre-apprenticeship or career navigation programs, workforce training programs, apprenticeship programs, or wraparound participant supports that are supportive of training persistence and completion.
• Capacity-building interventions are organizational and system-focused, rather than in direct service of participants, and may include, but are not limited to, proposals such as ecosystem-building, demonstration projects, technology or tool adoptions, or research, among others.

Frankenthaler Climate Initiative

The Frankenthaler Climate Initiative (FCI) is a pioneering grantmaking program established by the Helen Frankenthaler Foundation. Since its inception in 2021, FCI has distinguished itself as the foremost private national initiative in the United States dedicated to combating climate change specifically within the visual arts sector.

FCI provides visual arts institutions with up to $100,000 to undertake ambitious sustainability and energy efficiency initiatives that directly address carbon reduction and energy efficiency. The scope of its support is broad, encompassing everything from modest, rapid-response projects to comprehensive efficiency audits and feasibility studies, and extending to financial contributions for significant infrastructural renovations and strategic planning for new buildings and major initiatives.

Building on the core values of the Helen Frankenthaler Foundation, the initiative aligns a commitment to environmental stewardship with a belief in the vital importance of the visual arts and arts education. Through strategic funding and partnerships focused on tangible infrastructure, FCI aims to catalyze a sector-wide shift toward zero carbon operations, promoting a future where the visual arts thrive—while contributing to a more sustainable and ecologically conscious world.

Who We Fund

FCI funds nonprofit institutions in the United States and its territories whose primary focus rests in the visual arts. The visual arts includes but is not limited to painting, drawing, sculpture, printmaking, photography, and installations in clay, glass, metal, wood, fiber, paper, film, and mixed media.

Most of our grantees are art museums, nonprofit galleries, archives, noncollecting institutions, art schools, university museums, and artist-endowed foundations.

What We Fund

FCI funds energy efficiency and clean energy generation projects.

FCI meets arts institutions at every stage of the work, through four kinds of grants:

• Catalyst — first actions and stand-alone projects with a quick turnaround
• Scoping — energy audits and assessments that establish a baseline
• Technical Assistance — detailed planning for technically demanding projects
• Implementation — comprehensive capital work addressing a building's environmental impact at multiple levels

Technical Assistance Grants

Technical Assistance grants support projects that have finished initial assessments, and need procurement and financing support for an identified efficiency project. This may include providing designs, specifications, or fees for working with energy services companies (ESCOs) for project support. These grants also support more complex studies or analysis required for pursuing major implementation projects. At the conclusion of a Technical Assistance grant, the applicant should be sufficiently informed to implement a project.

South Carolina Community Development Block Grant

The South Carolina Community Development Block Grant (“State CDBG Program”) is designed to aid units of general local government in improving economic opportunities and meeting community revitalization needs, particularly for persons of low- and moderate-income. The State CDBG Program has been funded through the State since 1982 by the U.S. Department of Housing and Urban Development (HUD) under the Housing and Community Development Act of 1974, as amended (Title I). 

CDBG Program Goals and Outcomes

The SC Department of Commerce seeks to improve the well-being of all South Carolinians in a manner that supports and enhances a high quality of life. The State CDBG Program supports the agency’s efforts to strengthen communities through revitalization and improvement of neighborhoods, public infrastructure, and the local economy. 

The three overarching goals of the HUD CDBG program are to provide decent housing, economic opportunities and a suitable living environment. Within the context of these goals, each project funded by the State must also meet one of three outcomes identified by HUD: affordability, accessibility, or sustainability. 

Local Match/Leveraging

CDBG projects are expected to leverage other public and private investments and serve as a catalyst for future development.

There must be a 10% match of the total CDBG request, unless otherwise approved, which can come from a variety of committed sources including other grants, loans, waiver of fees, public or private investments, and documented volunteer or in-kind contributions. Matching funds must be immediately available for the project at the time of application. 

Community Development Block Grant Categories

There are three broad grant program categories: Community Development, Business Development, and Regional Planning. The Community Development Program is further broken down into several subcategories to address infrastructure, community facilities, and local priorities.

Community Development Programs

Description

This program is designed to produce outcomes that improve citizens’ quality of life and create a competitive environment for jobs and investment by addressing priority community development needs. Activities should contribute to healthy, safe and sustainable neighborhoods and communities. These grants are designed to improve the quality of life for distressed and LMI communities. Community Development projects will compete within the following subcategories that have the same general submission requirements, except that the Ready to Go Program will not be funded in a competitive funding round.

Community Development Program Categories: Community Infrastructure; Community Enrichment; Local Priorities Program; and Ready to Go Program

Community Enrichment Grants

Outcome and Priorities

This program is designed to fund public facilities, services and other activities that strengthen existing communities and support a high quality of life within the following state priority areas:

• Economic competitiveness and resiliency
• Education and workforce development
• Safe and healthy communities

Project investments should contribute to quality of life and the long-term vitality of communities. Activities must have the broad support of citizens and local businesses. Buildings and brownfield sites should be owned by the local government. Note that costs for operating or maintaining public facilities are not eligible for CDBG, so building projects must demonstrate financial viability. Equipment for public service activities must be for new or expanded services and generally associated with a significant capital investment in facilities. Only major pieces of equipment that have a durable life of five years will be considered for funding.

Nonprofit organizations and eligible public entities in South Carolina can seek support for energy efficiency and conservation projects, broader environmental programs, education, and poverty solutions.
