Manufacturing companies significantly contribute to climate change through emissions from their activities. Due to increasing private and public ecological interests, companies must implement sustainable strategies to generate competitive advantages. However, understanding the complex trade-offs between environmental, economic and logistical objectives is essential. Such an understanding is facilitated by learning factories that simulate real production environments. Learning factories are limited in the number of participants, so extended tools are required. One scalable solution is therefore offered by digital simulation games. This paper introduces a digital simulation game for objectives between internal supply chain and sustainability. Participants make strategic decisions balancing environmental impact, cost, and production optimization, with immediate feedback on their choices to enhance comprehension of these interdependencies.
