Scenario analysis in social LCA, an experiment on Natura's cocoa soap Cássia Maria Lie Ugaya, Nara Tudela Haberland and Fabien Brones Natura, a leading Brazilian cosmetic company was a pioneer in experiencing LCA approaches in the country and recently performed a pilot project to apply the UNEP and SETAC Guidelines of Social Life Cycle Assessment. The study was developed for the company’s 150 g cocoa soap. Cocoa is consumed from a cooperative of small organic farms in the Amazon area. Specific data were collected and then the Subcategory Assessment Method (SAM) (Ramirez et al., 2012) was applied. In SAM, organizations are evaluated in four levels: A is given for organizations that upscale the good practice along the value chain, B for organizations that fulfill a Basic Requirement, and C and D depends on the context where the organization is located. Then an aggregation by working hours along the life cycle stages was performed for each subcategory (Haberland et al., 2013). The aim of the current study is to compare the cocoa soap with soap without cocoa. Then two different product systems were considered: (1) the current one, in which part of the soap is produced with cocoa and (2) the product system without cocoa. As the management is worse in small organizations than in big ones, the results showed that (1) was worse than (2). On the other hand, a social contribution was noticed for the workers and the community in scenario 2 due to the better prices than in the current situation. In this sense, another product system was taken into account, (3), in which it was considered the same product system of (1) but without the consumption of cocoa, which allowed the evaluation of the consequences for small farms in the case they no longer supply to Natura. The results showed that the comparison of products using (1) and (3) reflects better the impacts than (1) and (2).
