If the biogas leaked from landfills could be used as a vehicle fuel, the addition of greenhouse gases from leakage and the emission of carbon dioxide would be reduced. Does not increase the amount of greenhouse gases in the atmosphere. Emission of hydrocarbons, carbon monoxide and nitrogen oxide are low. In concentrated form, it is explosive. Gas has to be compressed.
Infrastructure is relatively well developed.
Many countries have access to it, and it is inexpensive. Eliminates 20 percent more carbon dioxide than gas. Emissions of hydrocarbons, carbon monoxide and nitrogen are low. In concentrated form, it is explosive. Tank occupies large amount of space.
