What is the average carbon emission per passenger per kilometer for a car?
3 Answers
On average, a car emits approximately 510 grams of carbon per passenger per kilometer. Introduction to carbon emissions: The carbon emissions of a car are calculated based on the consumption of fossil fuels like gasoline. Burning 1 liter of gasoline is equivalent to emitting 2.33 kg of CO2. Since cars with different fuel consumption rates will consume varying amounts of fuel per unit of time, it is necessary to calculate the hourly fuel consumption based on the car's displacement and then determine the carbon footprint. New carbon emission standards: The new standard for tailpipe pollutant emissions is 30% lower than the current Phase II standards implemented in China. It will come into effect nationwide on July 1, 2007, with Beijing adopting it earlier this year.
As a young person who has long been concerned about environmental protection, I am truly mindful of automotive carbon emissions. The average small car emits about 90 grams of CO2 per person per kilometer—a number that may sound small, but cumulatively has a huge impact on climate change. I often think that if everyone drives a fuel-powered car to run errands, the air quality in the entire city will deteriorate. Therefore, I recommend prioritizing electric or hybrid models, which can cut emissions by half or even more, or opting for carpooling—filling a car with 4 people reduces each person's emissions to around 20 grams. Daily habits also matter, such as avoiding sudden acceleration, which saves fuel and is eco-friendly. Honestly, driving a small car alone isn’t cost-effective—the health of our planet requires us to pay attention to the details.
Over 30 years of driving experience has taught me that vehicle emissions are a tangible cost issue. On average, a passenger car emits about 100 grams of CO2 per kilometer per person, depending on the model—compact cars like the Toyota Corolla may only emit 70 grams, while large SUVs can soar to 150 grams. Fuel efficiency directly impacts your wallet: driving 10,000 kilometers annually means higher emissions costs when fuel prices rise. I recommend regular engine and tire maintenance—underinflated tires waste 5% more fuel, increasing emissions. Nowadays, car-sharing is popular in cities; splitting a ride among several people cuts emissions in half and saves on parking fees. Overall, energy conservation and emission reduction aren't just slogans—they're money in your pocket. Choosing the right car creates a win-win situation.
