Abstract: Life cycle assessment in general and that of cocoa specifically tends to lack completeness in examining the ecological impact as well as in examining uncertainties and variations. The study presented in this paper is a first step towards closing this gap. It focusses on agricultural practices of cocoa beans, taking into account 16 impact categories, and puts these results into the context of the value chain of cocoa liquor produced in Switzerland. Variations related to the different inputs are evaluated together with a comparison between countries, provinces, and cocoa varieties. It was found that cocoa cultivation is the driving factor of the ecological impact along the value chain for all impact categories. Large variations were found for all inputs to the extends that expected correlations between inputs like fertiliser usage on yield become blurred which hinders a proper analysis. Necessary steps forward are discussed.
