The biofuels industry has grown rapidly in the past decade, driven by government blending requirements and clean fuels standards in major economies. There is potential for significant new demand for biofuels from the aviation sector, which is looking for ways to meet its goal of carbon neutral growth by 2020, and from the maritime sector, which recently announced greenhouse gas (GHG) emission reduction targets. The ways these policies account for reductions in GHG emissions from biofuels are disputed. One particular area of controversy is the role biofuels play in driving tropical deforestation.
