The Covid health crisis, which brought the events industry to a sudden standstill for many months, nevertheless enabled its players to initiate, pursue or reinforce in-depth reflection on the sector’s environmental issues and challenges. For some, it was also an opportunity to seize development opportunities, with strategic investments in design and consultancy. In a sector that is by its very nature ephemeral, the question of sustainability is now central, and solutions are emerging everywhere. Online ordering platforms, work on materials, reconditioning and reuse of booths, upcycling of materials: whether they be practical or technical, innovations are pouring in and customers are following! So much so, in fact, that companies that use modular stands and solutions are increasingly turning to events professionals for permanent fixtures and fittings in sales outlets and agencies. Or when the ephemeral becomes sustainable.
