The quantification of fossil-fuel derived carbon dioxide (CO 2ff ) emissions is critical for regional carbon budgets. Radiocarbon ( 14 C) is an effective tool to estimate the contribution of CO 2ff to the total atmospheric CO 2 . In the present study, we have determined the spatial distribution of fossil fuel derived CO 2 across Delhi using 14 C measurements in Peepal tree leaves from April 2016 to March 2017 at city scale. Our analysis results show that the Δ 14 C values vary between –67.78‰ to 5.61‰ and corresponding CO 2ff values are varying from 1.63 ppm to 33.34 ppm. CO 2ff values from campus sites vary between 6.99 ppm to 16.38 ppm with an average value of 10.22 ± 3.20 ppm, while CO 2ff values vary from 2.41 ppm to 33.34 ppm with an average value of 13.32 ± 9.40 ppm for sites located in the parks. Further, we observed the higher contributions of fossil fuels in the CO 2 from northwest Delhi, central Delhi, and some parts of east and southwest Delhi. In the absence of real-time CO 2 monitoring, the results of this study provide a potential method for analyzing the contribution of CO 2ff values over the urban landscape to total CO 2 over the study region
