This study examines the intersection of campus sustainability, real estate value, and Environmental, Social, and Governance (ESG) principles within higher education institutions (HEIs). Drawing on empirical evidence from university sustainability frameworks and real estate valuation literature, we develop an integrated model that demonstrates how sustainable campus practices enhance both institutional reputation and property asset values. Our analysis reveals that universities implementing comprehensive ESG strategies experience significant improvements in their campus real estate valuations, with sustainability-certified buildings commanding premium values of up to 15% compared to conventional structures. The findings indicate that higher education agglomeration positively influences firm ESG performance through human capital development, while campus sustainability initiatives create tangible financial returns through energy efficiency, reduced operational costs, and enhanced stakeholder engagement. This research contributes to the emerging literature on sustainable university management by establishing quantitative linkages between ESG implementation and real estate value creation, providing a roadmap for institutional decision-makers seeking to align sustainability objectives with financial performance.
