This dataset captures the details of how CO2 emissions by a vehicle can vary with the different features. The dataset has been taken from Canada Government official open data website. This is a compiled version. This contains data over a period of 7 years. There are total 7385 rows and 12 columns. There are few abbreviations that has been used to describe the features. I am listing them out here.
Model 4WD/4X4 = Four-wheel drive AWD = All-wheel drive FFV = Flexible-fuel vehicle SWB = Short wheelbase LWB = Long wheelbase EWB = Extended wheelbase
Transmission A = Automatic AM = Automated manual AS = Automatic with select shift AV = Continuously variable M = Manual 3 - 10 = Number of gears
Fuel type X = Regular gasoline Z = Premium gasoline D = Diesel E = Ethanol (E85) N = Natural gas
Fuel Consumption City and highway fuel consumption ratings are shown in litres per 100 kilometres (L/100 km) - the combined rating (55% city, 45% hwy) is shown in L/100 km and in miles per gallon (mpg)
CO2 Emissions The tailpipe emissions of carbon dioxide (in grams per kilometre) for combined city and highway driving.
As number of miles a vehicle can travel with one gallon increases carbon Emissions decreases. Fuel Consumption Comb (mpg) is negatively corelated with CO2 Emissions We can see that Large size engines consumes more fuel and emitt large amount of carbon emissions. We can observe that as per gallon number of miles a vehicle travels increases carbon emissions decreases. It implies that less fuel consumption vehicles emitt less carbon emissions. Ethanol emitts more amount of carbon dioxide. we can observe that the most used type of fuel is Regular gasoline (X) and there is NO cars in this dataset uses Natural gas (N). We can observe that the SUV-SMALL class is the most pouplar in this dataset.
We can observe that most of the costly brand cars like BUGATTI and LAMBORGHINI are emmitting lot of carbon emissions and brands like HONDA and FIAT are least carbon emitting vehicles. We can see that Large size engines consumes more fuel and emitt large amount of carbon emissions. we can observe that the higher the number of cylinders, the higher the CO2 emissions.
