The aviation industry faces significant challenges in reducing the environmental impact of global air traffic. This results in the goal of net zero emissions by 2050. Innovations and new technologies must be implemented along the entire value chain to achieve this goal. In this context, investments and decisions have to be evaluated based on their potential to reduce environmental impacts. One method for operationalizing these issues is the life cycle assessment framework. This paper presents an analytical decision model for the potential assessment of LCA at aircraft manufacturers. The basis of the model is the derivation of criteria for the assessment and the identification of use cases along the value creation process. Based on the decision model, first concrete application scenarios are identified. (Only in German)
