Social life cycle assessment in the chocolate industry: A Colombian case study with Luker Chocolate

Abstract

PurposeChocolate is a widely consumed product and consumers are increasingly interested in its sustainability. However, the lack of scientific studies covering the social dimension hinders a holistic assessment of the sustainability. A social life cycle assessment (S-LCA) was conducted in cooperation with a Colombian chocolate manufacturer following the Guidelines for S-LCA of Products and Organizations 2020. This study represents the first application of S-LCA in the chocolate sector covering both cocoa cultivation and chocolate manufacturing.MethodsThe study aimed to identify the main social hotspots within the value chain of a dark chocolate product, as well as to identify the potential and actual social performance of this product. The stakeholders assessed in the study were workers (in the cocoa plantation and manufacturing plant), society, and the local community. Primary inventory data was collected through on-site semi-structured interviews as well as through the review of company reports. Secondary data used to build the reference scales for impact assessment were taken from national regulations and best practice standards. In total, 16 subcategories were assessed.Results and discussionThe overall results showed an outcome of at least a compliance level (0), and a performance beyond compliance (+ 1 or + 2) for the local community and society. The latter was attributable to the role of the company as an agent of change in a region heavily impacted by violence and poverty. Furthermore, numerous interviewees stressed the importance of companies in the Colombian post-conflict context to re-integrate former conflict actors back into the labor market. For workers, the results also indicated a performance on the compliance level or above, with child labor and health and safety scoring as + 2 and social benefits/social security scoring as + 1. Areas of improvement were identified in subcategories where the score was on the compliance level (0) such as working hours, fair salary, equal opportunities, and employment relationships.ConclusionsA main challenge encountered was the definition of reference scales for subcategories with no recognized standards applicable to the socio-political context. This suggested a necessity for further S-LCA applications in regions with armed conflicts. The study provided insight into the social sustainability of the chocolate industry across the life cycle, covering the cocoa plantation and the manufacturing plant. At the same time, it provided the company with a tool to measure the positive and negative social impacts of their actions on stakeholders and redirect efforts towards the areas most in need.
