One of the aims of energy policies is reducing CO2 emissions. In transports bio-fuels are one of the alternatives. Brazil is the world leader in producing ethanol from sugar cane. Prejudice against imports of Brazilian ethanol in US and EU markets is unjustified, as it represents the best ecological balance and does not reduce production of basic food in Brazil. As to biodiesel on the basis of soybeans social and ecological reserves partly are in order. Regarding ethanol industrialized countries should not use exaggerated criteria as to sustainability of production as pretext for protecting their own producers from imports of cheaper Brazilian bio-fuels.
