The Biofuels International website reports that some aviation industry stakeholder organizations have joined together to form the Brazilian Alliance for Aviation Biofuels. The alliance aims "to promote public and private initiatives that seek to develop and certify sustainable biofuels for aviation". The organizations include: Algae Biotechnology, Amyris Brazil, the Brazilian Association of Jatropha Producers, the Brazilian Aerospace Industry Association, Azul Brazilian Airlines, Embraer Association, GOL Airlines, TAM Airlines, TRIP Airlines, and the Brazilian Sugarcane Industry Association. The alliance believes that biofuels hold "the key for insuring the expansion of the aviation industry". The aviation industry, according to the United Nations Intergovernmental Panel on Climate Change (IPCC), accounts for approximately 2% of the global carbon dioxide emissions. With increasing concerns surrounding greenhouse gas (GHG) emissions from fossil fuels, aviation companies are becoming increasingly involved with a number of different projects in order to advance the development of sustainable aviation biofuels..
