What does the Saint-Denis Convention mean in practice for those planning and delivering sporting events? In this session, Thyr Rodrigues and Rodrigo Cavaleiro explore the Council of Europe’s Saint-Denis Convention, the only binding international framework promoting an integrated, multi-agency approach to safety, security, and service at sporting events. The session will outline the purpose of the Convention, its core principles, and the role of the S4 Committee in overseeing its implementation and supporting cooperation between public and private stakeholders. The discussion will examine how the Convention’s principles are translated into operational practice, highlighting practical considerations, approaches, and available tools that may be relevant to GCMA members seeking to strengthen collaborative planning and crowd safety within their own contexts.
