By reducing the ambition of the agenda in international climate negotiations, as countries have not committed to national goals for overall Greenhouse Gases (GHG) emissions reductions, the idea of “sectoral targets” gains strength. Some sectors of the economy, regardless of the country, have specific goals to set standards of reducing “carbon intensity” per unit of output.The aviation industry currently generates about 2% of global anthropogenic greenhouse gas (GHG) emissions. While new aircraft and engine technology, fuel conservation and improved airspace traffic management will help reduce aviation GHG emissions, over the longer term, these advances alone may not be sufficient to offset the projected growth in air travel and emissions. Aviation fuel usage increases at an annual rate of 9% in Brazil. Developing alternative and sustainable sources of this fuel is thus an issue of national significance.Many the different actors, among governments, as well as the investor community and airlines are committed to providing a low carbon and sustainable fuel that can be used in the current and future fleet, with the certainty that this fuel meets the required specifications, at a reasonable price.The development of new technologies for sustainable aviation biofuel has the potential to offer the most significant long term contribution to reduce emissions of GHG from aviation. Promising technologies to convert biological materials into jet fuels such as biokerosene have been developed and some have been approved for commercial use.
