Project-based industries (PBIs) and more specifically the motion picture industry (MPI) are industries with fluid workflows composed of non-standardised routines. The constant and massive employment of resources on an industrial level (energy usage, waste production, ephemeral decors, food consumption, transportation) generates a considerable negative impact on the environment. These industries are not striving towards sustainable development due to their ever changing work processes but have still not suffered from consumers’ backlash as many others are currently experiencing (fast fashion).Nonetheless, sustainability reporting (SR) is a rising phenomenon among MPIs due to an increased awareness about climate change and the need to shift business priorities towards a triple bottom line approach.With the employment of the major theories traditionally used to explore sustainability reporting, this thesis analysed the current stage of sustainability reporting practices in project-based industries with a focus on the motion picture industries in Europe (UK, France, Italy and Sweden). To reach this purpose, a theoretical tryptic supported the argumentation: the institutional theory, legitimacy theory and stakeholder theory were employed in synergy.Eventually, researchers confirm that SR is a rising practice and that it is not harmonised among its users. Given the lack of tailored legislative framework, organisations adventure themselves into self-assessment and third-party assessment with incohesive methodologies. Overall the motivations behind such a transition mainly emanate from personal conviction for sustainability, rather than established institutional or social pressure. Lastly, collaboration and stakeholders considerations are a reality and contribute to a more genuine engagement of MPIs into SR.

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.
