On a global scale, four constituents of greenhouse gas (GHGs) namely, carbon dioxide (CO₂), nitrous oxide (N₂O), methane (CH₄) and fluorinated gases (F-gases) have undergone significant rise due to human activities. CO₂ from road transport is the main contributor among constituents for GHGs emissions. The current study analyzed 42 fueling vehicles for determining CO₂ using vehicle brand, vehicle model, engine size, cylinder numbers, transmission types, fuel types and fuel consumption as input. The python 3.0 program was used to determine the influence of fueling vehicle factors on CO₂. Based on brands, Bughatti produced highest CO₂ (~ 500 g/km) while Smart brand found with less CO₂ (~ 50 g/km). Likewise, VAN-Passenger among fueling vehicle class produced highest CO₂ (~ 400 g/km) while least CO₂ (~ 200 g/km) observed in Station Wagon –small. Based on engine size, CO₂ generated from small size was less as compare to large size. The direct relation of CO₂ with cylinder number (R² = 0.69) and engine size (R² = 0.72) of fueling vehicle were determined. Fueling vehicle with 3 cylinder produced CO₂ 100–200 g/km, while 500 g/km generated with 16 cylinders. Based on transmission type, automate manual with 5 gears (AM5) has low CO₂ (150 g/km) while automatic with 7 and 10 gear (A7/A10) produced highest CO₂ (300 g/km). Based on fuel types, natural gas (N) produced least CO₂ while ethanol (E85) and premium gasoline (Z) fuel causes highest CO₂ (> 250 g/km). CO₂ emission recorded highest on City road as compared to highway and combine (55% city + 45% highway road).
