Earlier this month EPA proposed a partial waiver that would reduce the requisite amount of cellulosic biofuels that needed to be blended into the nation’s fuel supply, as stipulated by the RFS, for the 2024 compliance year. In testimony, however, Growth Energy General Counsel Joe Kakesh warned that following through on the waiver could set a dangerous precedent for future retroactive reductions, and would undermine the growing market for cellulosic biofuels, which are biofuels produced from leftover plant parts like stems, leaves and other fibrous material.
