Replacement of conventional fuels with biofuels is also generating adverse ecological consequences. Most of the feedstocks needed for processing take place in developing countries mainly in Latin America and Asia most of these countries are cutting down large areas of tropical forests for growing biofuels. For the production of clean fuels it is necessary to use dirty fuels as energy source. For instance intensive sugar cane crops for ethanol or other oil crops for biodiesel will need petroleum products fertilizers insecticides fuel pumps transport and industrial processing. Therefore it is possible that pollution levels increase by using dirty energy sources for producing and exporting clean energy sources. So far it is clear that bio in biofuels must have a question mark. Then it can not be neither justified nor adopted policies for biofuels promotion and support based on ecological arguments or in industrialized countries where people want to use agro-energy or in developing countries where people want to produce them . To classify biofuels as bio it would necessary to grow in degraded and poor soils that are unsuitable for food production the so-called second generation biofuels . This prevents the rising prices of food and deforestation. An international certification scheme could ensure the sustainability of agricultural practices for the production of raw materials for biofuels. In order to reduce possible impacts caused by biofuel production certification for procedures of its production have been developed around the world this is how the Dutch government among others aims that imported biofuels are certified according to environmental and social criteria. Certification of the entire process shall be necessary to ensure the world sustainability production
