At our EXPOs we always try to answer some of the most challenging questions our corporate partners are currently facing. Even though the last months were strongly influenced by the COVID-19 pandemic, the topic of sustainability, in all its facets, is still very relevant for every company, no matter from which industry. As companies follow different strategies in order to reach their sustainability goals and to implement their zero net strategies (based on the European Green Deal), the panel seeks to answer the question of how collaboration between major industry firms and startups across industries can facilitate solutions for the companies to reach these goals. By looking at the topic from different perspectives along the value chain, the panelists will share their experiences of such partnerships and discuss the challenges and central learnings of the collaboration processes.
