EPA has finalized pathways for production of renewable fuel from giant reed (Arundo donax) and napier grass (Pennisetum purpureum) as feedstocks. These pathways are for cellulosic biofuel, for purposes of the RFS. In response to comments on the proposal concerning the potential for these crops to behave as invasive species, EPA is adopting additional registration, recordkeeping, and reporting requirements that were developed to address the potential for GHG emissions related to these concerns.
