Global South Urbanization is a complex issue, with rapid urbanization, ecological and social inequities that interact and thus, sustainable urban development should be an urgent issue. In this setting, two theoretical solutions Ecological Modernization Theory (EMT) and emergent paradigm of Neo-Urbanization may prove useful in resolving the technologization advancement, ecological care, and social integration. Although the existing body of knowledge has proved the applicability of such models in developed economies, little is known about the applicability of the concept of these models in less developed economies, like India, which is resource-limited. This gap has been addressed in this chapter by talking about how the Indian urban and infrastructural projects can be used as experimental platforms to construct climate-resilient and socially equitable development in line with the Sustainable Development Goals (SDGs) SDG 11 (Sustainable Cities), SDG 7 (Clean Energy), and SDG 13 (Climate Action). The research methodology is the multi-case analysis qualitative method, and a total of seven model projects were identified where the green infrastructure, forms of government participatory, and environmental novelty were experimented, including Magarpatta City SEZ, Cochin international airport, Palava Smart City, Auroville township, and Indira Paryavaran Bhawan. Types of data sources used are the planning materials, sustainability reports, peer-reviewed literature, and specific performance measures of the site. These results show that the projects incorporate renewable energy systems, water sensitive planning, circular waste management, and community-based governance concepts in their development models. By so doing, they confirm fundamental postulations of EMT that it is possible to have environmental protection and economic development reinforcing each other, as well as illustrate the neo-urbanization reconciliation of regenerative and inclusive urban regeneration. Considerably important, the projects feature how grassroots involvement and the indigenous knowledge systems can complement the technological informativeness, confronting the supremacy of Global North-focused sustainability discourses. This study, by applying a combination of theoretical and empirical data, leads to a new integrative paradigm, according to which EMT and neo-urbanization are integrated so that Indian cities can be a force of sustainability instead of a source of environmental pressure. The chapter provides a lesson to be used not only regionally, but also globally as it provides a blue print that can be replicated to rethink urban development as a co-evolutionary process among human settlements, technology and ecosystems.
