The Indian government's 'Smart Cities Mission' aims to create 100 self-sustaining smart cities to improve living standards and promote economic growth, using technology for urban development. Following the budget speech in 2020, five new smart cities are proposed to be built under a public-private partnership model, while existing initiatives have launched around 5000 projects across various cities. Despite challenges such as funding and administrative hurdles, the initiative has resulted in significant improvements in several cities over its six-year timeline.
