The demand for sustainability on this earth is more prominent than ever. The global climate crisis affects everyone, and the movie industry's massive annual emissions are certain. However, the movie industry has not yet been investigated in-depth nor held accountable for its environmental impact. In the literature, environmental regulations of powerful institutions, such as the European Union, have been influential for sustainable change. Hence, this thesis will examine the interface of project-based organizations, environmental regulations, and sustainable practices through an exploratory approach. Precisely, this thesis aims to examine the influence of environmental regulations on project-based industries, using the example of the European movie industry with a focus on Germany and Italy. The research questions focus on the aspects of pressures and impacting factors along the supply chains of moviemaking. Lastly, it is also examined how stakeholders are affected by EU regulations. Data is gathered through a qualitative approach, using semi-structured interviews, and analyzed through the theoretical frame of institutional and stakeholder theory. The results of this study reveal that there is currently no specific impact of EU regulations on sustainable practices in the movie industry. Also, currently, no EU laws affect the defined stakeholders in the film business. Instead, it could be found that national legislation and infrastructure, private sector engagement, and organizations' self-commitment are impacting the industry to become more sustainable. Moreover, the movie industry's structural factor as project-based affects cooperation, communication, and laws for sustainability. This thesis serves as a groundwork for further research and practical implementations for sustainable filmmaking.
