Mission & Focus Areas

The Foundation’s stated mission is to advance the competitive future and quality of life of Southwestern Pennsylvania and to protect, preserve, and restore America’s environmental heritage. Its six programs are Conservation, Economic Development, Economic Mobility, Health & Well-Being, Organizational Effectiveness, and Social-Impact Investments.

The Foundation describes its conservation work as protecting and stewarding habitats and natural amenities, alongside approaches such as renewable energy and new technologies. Its regional programs address economic growth, economic opportunity for children and youth in Allegheny and Westmoreland counties, and health in those counties, particularly for vulnerable residents. Organizational Effectiveness supports partners’ organizational capacity; Social-Impact Investments provide risk capital and other resources to mission-driven for-profit companies.

Recent recipients illustrate the range of organizations supported. The University of Pittsburgh describes itself as a public research university serving its home region, Pennsylvania, and the nation through education and research. The Children’s Hospital of Pittsburgh Foundation says it raises funds for the hospital’s work in children’s health, care, teaching, research, and advocacy. The Citizen Science Lab describes its mission as creating hands-on STEM experiences for diverse and marginalized communities. The American Prairie Foundation says it seeks to create a large nature reserve for people and wildlife.

Grantmaking

In filing year 2024, the Foundation reported 296 grants totaling $116,670,323. Individual grants ranged from $2,000 to $10 million, with a median of $220,000.

Among the largest 2024 awards were $10 million to the University of Pittsburgh for a Hazelwood Green facility focused on manufacturing cell, gene, and antibody-based therapies; $7.5 million to Carnegie Mellon University for a new science building in Oakland; $7 million to Carnegie Mellon to establish a Manufacturing Futures Institute at Hazelwood Green; and $5.5 million to Carnegie Mellon for a robotics innovation center there. Other large grants included $4.5 million to the American Prairie Foundation for property acquisition in northcentral Montana and $2.1 million to the Children’s Hospital of Pittsburgh Foundation for research and scientist retention.

The Foundation’s website says its nonprofit General Application has no deadline and can request general operating or project-specific support, as well as planning, innovation, implementation, or scaling support. The For-Profit General Application is also available without deadlines. The Foundation’s filing says applicants may apply online and that it prioritizes proposals with clearly defined outputs, outcomes, and an evaluation component. Applicants must be charitable, tax-exempt organizations with a valid IRS tax ID or government entities. It does not consider requests on behalf of individuals or from outside the United States, and it does not encourage requests from outside Pennsylvania. Economic Development, Economic Mobility, and Health & Well-Being proposals must focus on Allegheny and/or Westmoreland County. The Foundation says it generally is not providing multi-year grants at this time and that most grants are for 12 to 18 months.
