The paper proposes a Public-Private-Philanthropy Partnership (P4) model to integrate CSR funds into PPPs for sustainable infrastructure in India. Using Andhra Pradesh as a case study—where CSR spending reached ₹3,707.43 crore (2018–2023)—the paper outlines a PPP Trust as a financial intermediary to channel CSR, government, and multilateral resources into rural and urban projects. Supported by an Asset Management Company for financial viability, the model highlights global precedents, assesses benefits and challenges, and offers policy recommendations for nationwide adoption.
