The coffee sector is one of the pillars of the Colombian economy. It generates nearly 800 thousand directs jobs at the rural sector and about 1,6 million indirect jobs, because it occupies people all over the value chain. Although its social value, the coffee is going over a crisis where it opens a consideration about the current production models, starting from a Life Cycle Thinking. Therefore, the aim of this study is to make the Life Cycle Assessment (LCA) from one (1) Kg of parchment coffee in two crops from San Francisco, Colombia, the first, certified with Rainforest Alliance and the second, a technicized crop. The environmental impacts of the product were identified, based on ISO 14044:2006. The information considered for the study, were the incoming and outgoing of the system (water usage, energy consumption, raw material, liquid and solid waste, land usage and co-products), which were compiled through the application of questionnaires to producers. The limits of the system, where selected based on the internal processes of the studied crops: from the delivery of the coffee tree ‘cafeto’ until the drying phase. Finally, the consumption of resources associated to the production of 1 Kg of the parchment coffee was established. At the same time, it was verified that the certificated crop presents a lower use of resources during the different processes immersed in the limits of the system, and, that the phase of benefit of coffee presented less environmental burden in comparison from the technicized crop.
