<p>Fuel compositions exhibiting reduced greenhouse gas (GHG) emissions, based on a lifecycle assessment from the time of cultivation of feedstocks (in the case of plant materials) or extraction of feedstocks (in the case of fossil fuels) required for the compositions (up to and including the ultimate combustion of the fuel composition by the end user) are disclosed. The reduced level of emissions ("carbon footprint") is achieved by incorporating a pyrolysis derived component having a higher heating value than ethanol and meeting other applicable standards for fossil fuel (e.g., petroleum) derived components conventionally used for the same purpose, such as transportation fuels. Advantageously, fuel compositions comprising pyrolysis derived gasoline can exhibit lower GHG emissions than gasoline derived solely from petroleum, or even conventional blends of petroleum derived gasoline and ethanol.</p> |
