The United States is the largest contributor to aviation CO2 emissions in the world–responsible for more than a quarter of all carbon dioxide emitted from flying. Full decarbonization of U.S. aviation fuel use could be achieved by substituting conventional jet fuel with sustainably produced biofuels. Planting the grass miscanthus on 23.2 million hectares of existing marginal agricultural lands (which often lays fallow or is poor in soil quality) across the nation would provide enough biomass feedstock to meet the liquid fuel demands of our aviation sector fully from biofuels, an amount expected to reach 30 billion gallons/year by 2040.
