Alternative fuels and advanced vehicle technologies offer opportunities for significant reductions in emissions and increases in efficiency.
Different alternative fuels and technologies are in various stages of development. Each have unique performance and emissions characteristics.
Alternative fuels include
Depending on the feedstock and the process used to make these fuels, they can be very low or very high in greenhouse gas (GHG) emissions. For example, methanol made from coal would approximately double GHG emissions compared to conventional gasoline, whereas methanol made from natural gas would be slightly lower than gasoline and made from cellulose would be about 60% lower.
