The Outlook assumes biodiesel use to be held constant over the remaining years although no explicit mandate for biodiesel is legislated thereafter, the subsequent mandates referring only to advanced biofuel. Trade of biodiesel should remain low, Argentina is expected to be the main supplier on international markets. While many developing countries, especially in sub-Saharan Africa and in South East Asia, have initiated ambitious renewable energy programmes, many have been put on hold during the economic crisis, credit constraints and with the more uncertain market prospects. The OECD-FAO Agricultural Outlook, therefore, presents a conservative view on biofuel prospects in many of the developing countries over the projection period.
