Increased demand for biofuels is expected to produce changes in the present land-use configuration. Furthermore there is a growing concern about the effect of land-use change on biodiversity, food supply, soil and water quality. The present report reviews the current effort made worldwide to address this issue. A description of land-use concepts is first provided followed by a classification of ILUC sources. Then, a discussion on the implications of including ILUC emissions in the GHG balance of biofuel pathways and a review of methodologies being developed to quantify indirect land-use change are presented. The question of methodological choices in LCA to account for ILUC is also addressed. The approaches to account for this effect in carbon reporting initiatives are discussed. Finally, recommendations and further research work are described.
