Abstract
The present study was carried out for more than three decades (1990-2022) to evaluate the trend of atmospheric carbon dioxide level at three stations in the megacity of Kolkata. The city is experiencing high population density and horizontal expansion in recent times for providing space to housing complex, shopping malls, industries, offices etc., mostly at the cost of the producer community in the city. The spatial order of near surface atmospheric carbon dioxide level is Park Street (Stn.1) > Lake Town (Stn.2) > Garia (Stn.3). The percentage increase of atmospheric carbon dioxide is 12.22, 9.71 and 10.96 at stations 1, 2 and 3 respectively. Both at stations 1 and 2, the increase of atmospheric carbon dioxide per year is 1.39, while at station 3, the value is 1.24. The rising trend of carbon dioxide in the city has the probability to cause adverse effects on the ecology and environment of the city by way of increasing the ambient air temperature and other related negative impacts.
