Urban sector is posing serious challenges presently and is likely to become an issue of great global concern in future. Around 55 percent of the total global carbon footprint is contributed from the urban sector. The resulting contributing factors are mainly on account of continuous increasing urban population, non-optimization of concreting to non-concreting urban surface and vertical to horizontal spread of urban area coupled with other environmental parameters of relevance. These environmental issues are in the form of insufficient urban air ventilation, increasing urban heat island, inadequate carrying capacity of road network leading to traffic congestion resulting into enhanced air pollution, inadequate disposal and treatment of municipal solid waste and sewage and so on so forth. To address issues referred to above, an attempt has been made by the authors to design pollution free ideal city with reference to environmental issues coupled with circular economy and sustainability in the present paper. Such an ideal city is presently for a population of 1 lakh but will be designed and planned for a predicted population in the year 2051 and accordingly forecasting done by different methods. On the designed population of 2051, the area of the city estimated using WHO norms of 50 square meters per person as open space. The water consumption, sewage generation, solid waste generation also estimated in the present paper along with revenue generated by transforming waste into usable products. Moreover, around 40 percent urban area is kept as green area where organic farming is developed, and revenue earned. In addition to above, an ideal city is designed to have adequate air ventilation, balancing concreting to non-concreting urban space to reduce urban heat island and thereby reduction in urban energy demand. All the rainwater will be collected and stored and is used to cater population demand. The revenue earned from transformation of waste to usable products, organic farming, reduction in energy demand, recreational and commercial activities, etc will provide adequate input to circular economy and sustainability. essment process for sustainable environmental climate change and control towards sustainable development.
