Minimising the environmental impact and contributing to combat global warming are increasingly a concern, and scientific research is no exception. The size and nature of particle physics (PP) projects and facilities make such concerns even more relevant. CERN decided to become a role model for environmentally responsible research, and it is important that the global PP community keeps the pace. The European PP Communication Network (EPPCN) created a dedicated WG to enhance the communication on environment-related issues in CERN’s member states, to both internal and external audiences. A change in culture within the PP community and shift in perception in society are essential to helping save Earth’s global ecosystem… and for guaranteeing support to PP research and future projects!
