Over the past 10 years, the Government of India has increased its pace to build Smart Cities throughout the country to fulfill the target of sustainable goals under the flag of RIO Summit 1991. Millions of rupees are being allocated in different parts and regions of the country to build smart sustainable cities to be in the upgraded version of the comparable world scenario of developed nations. However, it was found that despite providing necessary supply to build smart urban environment, there is still a gap to fill this void. It is either for the approach method or for constraining in demand supply chain. To ensure this, the study has been conducted in different areas of Newtown Kolkata Development Authority with evidence of the noise level and the presence of suspended particulate matter. The road dust from highways and the roads and emissions from vehicular transit are the main constituents of respirable particulate matter. Apart from natural spontaneous sources, nonspontaneous sources may occur due to vehicular transit of citizens, which excludes source of eateries and construction sites. The standard error method for the source of sound level and its correlation to the level of particulate matter have been described. Probability has also been discussed for the use of cooling system within the vehicle, which is also a directional process for vehicular emission. The potential health effects of such activities are also discussed.
