How much CO2 does a plane produce compared to a car?

How much CO2 does a plane produce compared to a car?

Admittedly, air transport is extremely polluting – but so are cars. Air traffic represents less than 2-3% of the global CO2 emissions whereas road traffic accounts for around 10% of these direct emissions. Still, planes remain among the most polluting means of transport, together with cars.

How much CO2 does a 737 produce?

CO2 emissions from aviation fuel are 3.15 grams per gram of fuel [38] , which gives CO2 emissions from a Boeing 737-400 of 115 g per passenger km. At a cruising speed of 780 km per hour [Wikipedia, 28.2. 08], this is equivalent to 90 kg CO2 per hour. So for both aircraft, the emissions are around 90 kg CO2 per hour.

How much CO2 does a car produce per mile?

calculation gives the CO2 emissions from using oil as energy to be 3.67 tonnes per person….Derivation of the factor used.

Do jet planes pollute more than cars?

A single flight produces three tons of carbon dioxide per passenger, but the amount goes up dramatically if the plane is nearly empty. Driving a car solo has the same basic climate impact as taking an 80-percent-full plane flight a similar distance, the study said. If the plane is full, it beats the car.

Do planes use more fuel than cars?

Commercial jets have been more fuel efficient per person per mile than passenger cars for over a decade. In 1970, Sivak reports, it took 10,185 BTUs to move a person a mile in an airplane, compared with 5,067 BTUs to move a person a mile in a car—making flying twice as energy intensive as driving.

How much CO2 does a new car emit?

After a steady decline, newly registered cars emitted on average 0.4 grammes of CO2 per kilometre more in 2017 than the year before. To curb the trend, the EU is introducing new CO2 emission targets, which aim to cut harmful emissions from new cars and vans.

How many tons of carbon dioxide does a plane produce?

Airplanes are about 3 percent of total global climate emissions. A single flight produces three tons of carbon dioxide per passenger, but the amount goes up dramatically if the plane is nearly empty.

Is the CO2 in a car the same as NOx?

CO2 is not part of the same emission standards as NOx, PM and CO (ie Euro 6d). You can read more about emission standards in our guide to low emission cars.

Where does most of the CO2 in cars come from?

Most of this comes from passenger vehicles – cars and buses – which contribute 45.1%. The other 29.4% comes from trucks carrying freight. Since the entire transport sector accounts for 21% of total emissions, and road transport accounts for three-quarters of transport emissions, road transport accounts for 15% of total CO 2 emissions.
