Nowadays, there is a world demand for renewable energies. These kinds of energy must be sustainable to be considered renewable. The consumption of diesel has increased and so has the emission of greenhouse gases. Bio-diesel is an alternative to reduce this kind of emission. But, when the matter is bio-diesel, there are some challenges to be overcome. This first one is that this chain must be competitive. There are some criteria to evaluate the competitiveness of chains. Also, it is known that Brazil has a big potential to export this kind of fuel. However, some countries are developing norms to evaluate whether this fuel is sustainable and whether it has positive impacts in society. The present work creates a model to evaluate bio-diesel chain suppliers using competitiveness and certification criteria identified in this chain. Smarter methodology was used in order to do so. This model was put together along with a transport optimization model. It could be observed that the "selo social" has an important impact in transportation costs. When we analyzed competitiveness and certification evaluation models, we could observe that these suppliers evaluation model changes this relationship.
