Boosting biofuels: sustainable paths to greater energy security

Substantial potential exists to expand both food and fuel supply in a sustainable fashion. Sustainable biofuel pathways examined in this report include: boosting yields of food crops and associated residues on existing farmland; freeing up existing farmland for biofuel crops through further yield improvements; reducing losses and waste in the food chain to free up additional farmland for biofuel crops; and improving livestock management to free up pastureland for biofuel crops. The report also examines biofuel potential from: afforestation using fast-growing tree species; and cultivation of algae from organic waste streams or carbon dioxide.
