For every litre of petrol used 2.3 kilograms of carbon dioxide is released from the exhaust. For every litre of LPG used, 1.5 kilograms of carbon dioxide is released from the exhaust.
Carbon dioxide is the main greenhouse gas that contributes to global climate change.
A vehicle using LPG will have a higher fuel consumption than the same vehicle using petrol. This is due to different fuel densities between LPG and petrol. The greenhouse gas emissions for the LPG vehicle, travelling 15,000 kilometres annually, will be 3375kg compared to 4140kg of emissions when the vehicle uses petrol. 765 kg less greenhouse gases are being emitted each year from the vehicle using LPG, which is a better outcome for our environment. You can make a difference by choosing a vehicle that uses a fuel with lower greenhouse emissions.
