(NC)-Hold your arms out at your sides like the person in this illustration, and imagine there’s the same kind of bubble around you. That’s roughly the space 1 kg of CO2 takes up - the amount produced by every litre of gasoline you burn. Gasoline and diesel - which are injected into the engine as a mist of fine droplets - require oxygen to burn. That oxygen comes from air, but air is only 21% oxygen. So it takes about 8,000 litres of air, weighing almost 12 kg, to burn 1 litre of gasoline or diesel. And with so much air involved in the process - and with gasoline and diesel both containing large amounts of carbon to begin with - a lot of CO2 comes out the other end. It’s chemistry.
