That depends on how biofuels are produced. Sustainable biofuels are made of raw materials that are sourced from sustainable sources  Their supply chain meets the strict sustainability criteria set for biofuels in many markets (e.g. EU Renewable Energy Directive II in Europe).
In Europe, fuel is only considered sustainable when the fuel producer uses renewable raw materials that come from traceable sources. The producer has to prove that the raw materials do not come from farms established by clearing natural forests or other land of high biodiversity value after 2008.
