What is the carbon emission per kilometer for an average car?
2 Answers
An average car emits 270 grams of carbon per kilometer. Here are the relevant details: 1. Carbon emission calculation formula: Carbon dioxide emissions (kg) = fuel consumption (liters) × 2.7 kg/liter. Taking a National Standard III vehicle as an example, assuming an average daily travel distance of 5 kilometers and a fuel consumption of 10 liters per 100 kilometers, replacing driving with cycling can reduce carbon emissions by 1.35 kilograms (equivalent to planting 0.27 trees) and reduce toxic pollutant emissions by 21 grams. 2. Car-Free Day: The theme of "Car-Free Day" aims to take action for cleaner urban air, which not only requires government departments to implement practical measures to develop green transportation but also calls for the participation of every citizen.
I drive a lot and have done some research on emissions. On average, a regular car emits about 120 to 150 grams of CO2 per kilometer, depending on the vehicle type and driving style. For instance, smaller engine cars emit less, and driving smoothly without sudden acceleration can reduce it to around 100 grams. I've calculated that with a fuel consumption of 7 liters per 100 kilometers, the carbon emission is approximately 130 grams per kilometer, since each liter of fuel emits 2.3 kilograms of CO2. Driving habits make a big difference, with higher emissions in traffic jams. For more precise estimates, you can use the car's fuel consumption display or download an app for monitoring. Nowadays, eco-driving is encouraged, so I keep my tires properly inflated and avoid speeding, which saves money and reduces carbon emissions effectively, easily cutting 20 grams per kilometer.
