The blue economy was originally conceptualised as having a strong focus on social equity; however, in practice, these equity considerations have been overshadowed by neo-liberal capitalist agendas, which have become dominant in blue economy discourse. A continued expansion of ocean industry developments and activities has resulted in an inequitable share of the burdens and benefits of utilising ocean spaces and has exacerbated wealth disparities and power asymmetries. Therefore, finding mechanisms to reinstate equity as fundamental to blue economy governance and practice is increasingly important. However, there remain few practical examples that outline how to embed equity within blue economy governance and current frameworks for understanding equity are complex, often divergent and less focused on implementation. This paper outlines a new model for conceptualising equity that is clear and easily understood, captures equity's key components and dimensions, and covers key ethical concerns that arise in blue economy development. Furthermore, this model can be practically applied and embedded into governance structures. To demonstrate the model's application, the paper outlines one participatory approach to implementing the model in blue economy governance.
