Each aeroplane has a different rate of carbon dioxide emission depending on the size of its engines, the speed flown and the distance travelled. SAS has put together a calculator for many types of planes (See Link)
As a starting point, all hydrocarbon fueled machines emit about 2 kilograms of CO2 for each liter of fuel burned.
Too much !
1% of the worldds emissions
i dont know do the math
double the amount as planes.
A trip of 15000 km (approximate distance Heathrow--> Perth) on a large jet would relate 5.2 tonnes of CO2
some, but much less than the amount it absorbs. Also, as an alternative to fertilizer, it reduces co2 (fertilizer production admits a lot of co2)
Yes, plants do emit a small amount of CO2 at night through a process called respiration.
Yes, cars emit carbon dioxide (CO2) into the atmosphere as a byproduct of burning gasoline or diesel fuel.
Animals emit CO2 when they exhale.
No. Plants emit their own CO2 through respiration.
Yes, infact vehicles are considered to be the main contributor to the Co2 in the atmosphere
Volcanoes emit varying amounts of CO2 depending on their activity levels. On average, volcanoes release about 200 million tons of CO2 per year. This is a relatively small amount compared to human-generated CO2 emissions.
