The Sustainable Blue Economy Partnership (SBEP) is a Horizon Europe co-funded partnership bringing together over 74 institutions from 30 countries and the European Commission, pooling research and innovation investments to drive a sustainable blue economy across Europe's sea basins. JPI Oceans leads the communications, outreach and dissemination work package, and as that workload grew, the existing brand guidelines, focused mainly on logo usage and colours, were no longer enough to cover the full range of materials the partnership needed to communicate at scale.
