How do you calculate CO2 emissions per km?

An average consumption of 5 kg / 100 km then corresponds to 5 kg x 2252 g/kg = 113 g CO2/km.

What connection is there between fuel consumption and emission of carbon dioxide?

The amount of CO2 a car emits is directly related to the amount of fuel it consumes. For instance, a diesel car emitting 95g CO2 per kilometre consumes around 3.7 litres of fuel per 100km, while a petrol car consumes around 4 litres/100km for the same CO2 emissions.

How much CO2 is in a litre of diesel?

around 2.62 kgs
Burning a litre of diesel produces around 2.62 kgs of carbon dioxide, whereas petrol has a lower carbon content and produces about 2.39 kgs.

What are the emissions from a petrol engine?

The major products of the complete combustion of petroleum-based fuels in an internal combustion engine are carbon dioxide (13\%) and water (13\%), with nitrogen from air comprising most (73\%) of the remaining exhaust. A very small portion of the nitrogen is converted to nitrogen oxides and some nitrated hydrocarbons.

How much CO2 do cars emit?

A typical passenger vehicle emits about 4.6 metric tons of carbon dioxide per year. This assumes the average gasoline vehicle on the road today has a fuel economy of about 22.0 miles per gallon and drives around 11,500 miles per year. Every gallon of gasoline burned creates about 8,887 grams of CO2.

How much CO2 does a diesel car produce per km?

121.5 g CO2/km
On average, the CO2 emissions of diesel cars (121.5 g CO2/km) are now very close to those of petrol cars (123.4 g CO2/km). The difference of 1.9 g CO2/km was the lowest observed in the past 5 years.

Do cars produce CO2 or CO?

Do cars emit CO or CO2?

Carbon monoxide (CO) — cars emit carbon monoxide when fuel is burned. Breathing air with a high concentration of CO affects critical organs like your heart and brain. According to the Environmental Protection Agency, as much as 95 percent of all CO emissions in cities may come from motor vehicle exhaust.

How much CO2 do cars emit worldwide percentage?

The global transportation sector is a major polluter and in 2020 produced approximately 7.3 billion metric tons of carbon dioxide (CO2) emissions. Passenger cars were the biggest source of emissions that year, accounting for 41 percent of global transportation emissions.

How do you calculate carbon emissions on a car?

Fuel combustion emissions can be calculated using the emissions factor of 2.33 kg CO2e/litre. If your car average 8 L/100 km then you multiply this by 2.33 and divide by 100 to give 186 g CO2e/km for combustion emissions.
