Impact Investing: Financing Sustainability in Smart Cities in Tamil Nadu

Author(s) Ms.SRINITHI MEENAKSHI.N, Ms.KIRUTHIKA .K
Country India
Abstract Tamil Nadu is a leading state in India’s Smart Cities Mission, with 11 cities selected for development, including Chennai, Coimbatore, Madurai, and Tiruchirappalli. The financing of smart city initiatives requires innovative funding models beyond traditional government allocations, and impact investing has emerged as a key mechanism to drive sustainable urban transformation. Impact investing aligns financial returns with social and environmental benefits, supporting sectors such as renewable energy, smart infrastructure, waste management, and digital governance.
This chapter explores how impact investing has contributed to the sustainable financing of smart cities in Tamil Nadu. It examines key financial instruments such as green bonds, social impact bonds, venture philanthropy, and blended finance. A review of existing literature highlights both the opportunities and challenges of impact investing, including impact measurement difficulties, regulatory gaps, and investor confidence. The study employs a mixed-methods approach, analysing financial data, case studies, and policy frameworks. Findings suggest that while impact investing has gained momentum in Tamil Nadu, greater policy support and standardized impact measurement frameworks are needed to scale investments in smart urban projects.
