Abstract This research investigates the effectiveness and application of green infrastructure in urban contexts within five major Indian cities: Some of the major cities are Delhi, Mumbai, Bangalore, Chennai, and Kolkata. The research design also incorporates both qualitative and quantitative approaches including a literature review, case studies, surveys with 1000 residents, and interviews with 25 urban planning experts. The research findings show that green infrastructure has a positive impact on the environment, economy, and society. Green roofs in Delhi minimize stormwater and energy use whereas green belts and mangrove replanting in Mumbai lessen flood impacts and improve air quality. Bangalore’s rainwater harvesting has increased groundwater recharge while Chennai’s urban wetlands help in flood control and reduction in temperature. Kolkata’s community gardens not only enhance the green area of the city but also contribute to local food production. The analysis of the result is conducted and the results demonstrate the F-statistics value as 8.48 and the p-value as 9.90 x 10− 7. But there are some issues to consider including maintenance costs, funding, and public awareness. Thus, the study comes up with recommendations that green infrastructure should be supported through policies, community involvement, and integrated urban planning as crucial for sustainable urban development in India.
