PracticE Ecosystem for StandaRdS (PEERS) is a Horizon Europe project aiming to advance and reinforce the European Union's operational safety and security policies through the development of a practitioner-driven ecosystem focused on pre-normative / standardisation processes and supporting tools. The PEERS ecosystem supports the effective strengthening of preparedness and response in the field of CBRN-E through a co-creation approach resulting in the practitioner-driven Better Practice Guide initiative, gamification and e-Learning support. It primarily targets assisting Europe's CBRN-E practitioners, European research policymaking as well as other stakeholders including the research community and national standardisation bodies, who will be invited to join the PEERS Co-Creation Group for effective delivery. A comprehensive engagement and consultation governance mechanism with the Group will be therefore applied for the realisation of the ecosystem. Additionally, the ecosystem includes an integration capability to existing community-building platforms and a gamification strategy, aimed at encouraging solid user engagement, strengthening interactions activities, and furthering user training skills based on situational awareness. Within this landscape, we do hope that the PEERS approach will assist the transformation of how the needs of the targeted CBRN-E experts and policy-makers, in particular, are met for a more effective and sustainable way of operating in the future.
