    • -1 for reasons discussed in (1). We deleted that emission from the making feedstock estimate in Table 1 to substitute our own estimate in the column marked land use change. Table 1 retains a GREET-calculated credit for biomass in making feedstock to reflect the increased carbon sequestration in soils from growing switchgrass instead of annual crops.

    • The elasticity for the aggregate demand for grains is lower than the demand elasticities for individual grains. Demand for individual grains reflects the ability of consumers to substitute other grains when prices rise, whereas the aggregate demand for grains declines only to the extent that consumers reduce their demand for total food and feed. The amount of replacement cropland depends primarily on reduced demand for all grains
