This study explores public awareness and attitudes toward adopting green infrastructure (GI) for Sponge City implementation in New Delhi, India. A primary survey was conducted with 300 respondents to assess their knowledge, perceptions, and willingness to support Green Infrastructure practices, such as permeable pavements, green roofs, and rainwater harvesting. The study examines the role of socioeconomic factors including education level, homeownership, flooding experience, and income in shaping preferences for ecosystem services, such as flood mitigation, water quality, biodiversity enhancement, and recreational spaces. To analyze the survey data, descriptive statistics, Pearson's correlation, and binary logistic regression were employed. The results indicate that respondents with higher educational attainment and homeownership were more likely to support green infrastructure projects, while those with flooding experience showed a stronger preference for flood mitigation services. Additionally, the study explores factors influencing respondents' willingness to invest in green bonds for financing such initiatives. The findings suggest that education and community engagement are key to enhancing public support for Sponge City initiatives in New Delhi. Policy recommendations are provided to promote green infrastructure adoption through targeted educational campaigns, financial incentives, and inclusive planning processes.
