It may be a repetition but above all a good synthesis which supports some of the discussions we have had concerning LPG among others:

If we now consider gas as a clean fuel, there is, first, LPG (Liquefied Petroleum Gas). This fuel is a mixture of 50% butane and 50% propane, obtained from petroleum refining. The advantage of this type of fuel is that it contains no lead, benzene or sulfur and makes it possible to obtain, compared to petrol, a reduction in carbon monoxide emissions of 20 to 60%, carbon dioxide (CO2) of about 10%, hydrocarbons from 30 to 60% and nitrogen oxides from 15 to 40%.
