An ever-increasing number of companies set science-based targets and formulate sustainability strategies. Now they are challenged by the implementation of the strategy and the operationalisation of the targets within the organisation. Catering towards this need and filling an identified gap in the literature, this study aims to find a way to translate organisational-level sustainability targets to product-level and improve the capacity of design departments to design more sustainable products. This is done via a case study of the wind turbine manufacturer Vestas, who faces above-mentioned challenges. Utilising the example of Vestas’ science-based Scope 3 GHG reduction target, this thesis presents a process of translating the organisational-level target to product-level, including the identification of emission hot spots and definition of design departments’ respective contribution share towards the product-level target. Finally, it investigates the sustainability opportunities and barriers seen by the design departments and identifies design departments’ needs to be able to focus on the design of more sustainable products.
