The short answer to how burning 1 litre of dieselwill create2.68kg of carbon dioxide when burned in order to power a truck.
1 litre diesel, weighs around 840g but it produces 2.68kg of carbon dioxide. This CO2 is generated in the combustion process in the engine and is a potent greenhouse gas increasing the speed of global warming. To understand why the total carbon dioxide produced is heavier than the original litre of fuel, one needs to turn to the chemistry: diesel and petrol are full of carbon, but carbon is quite light. However when the fuel burns, the carbon combines with two oxygen molecules (both of which are heavier than the carbon molecule) to create carbon dioxide. Each oxygen molecule weighs in at about 25% more than a carbon molecule and then there are two of them. To put it into numbers, if carbon weighs 12, two molecules of oxygen weigh 32. What proportion of diesel and petrol are carbon? With diesel, about 720g of the 840g that one litre actually weighs is composed of carbon. With petrol around 640g of the 740g weightis carbon.
HOW PLANTING 460 TREES WOULD MOP UP SOME OF THE DAMAGE CAUSED BY CO2
One fully grown tree can absorb 21 kg of emissions from the atmosphere in 12 months. (www.viessman.co.uk) If one considers that one truck travelling 150 000 km a year and using, say, an average of 3L diesel per 100 km, then the truck will use approximately 45,000 L fuel. This amount of fuel, in turn produces (at 2,7 kg of carbon per L diesel – see explanation above) 121 500 kg of carbon which goes directly into the atmosphere and stays there, increasing Earth’s temperature. If you wanted to, you would need to plant 5786 trees annually just to mop up the CO2 ofone trucktry to imagine what would be needed to clean up after the millions of trucks on roads worldwide. However by fitting aerodynamics to a truck one can save not only 8%- 10% percent fuel,but also avoid creating 12 500 kg of CO2 (which otherwise would need to have an additional 4630 trees planted to absorb it). Then you will significantly reduce your own carbon footprint. If every truckwere able to save 8% of the fuel used then the world would much better placed to combat global warming. It’s not the total answer but it would be a really good start.
Based on one truck with:
- Yearly Mileage of 150,000 km
- Yearly Fuel Used: 45,000 litres
- Yearly CO2 produced:121,500 kg
- Fuel Saving (8% fuel saved with aero kit) would equal: 3,600 litres
- Additional trees needed to have been planted otherwise to absorb: 460
