This paper analyses newspaper coverage of ‘blue economy’ in the UK 2012–2020. It elaborates on Germond-Duret and Germond’s (2022) finding that UK media published a dominant development discourse concerning the UK’s marine space without reflecting on the risks of growth agendas. Articles from UK print media featuring ‘blue economy’ were compiled from LexisNexis then analysed to establish patterns of publishing, the investors, investments and projects reported, the experts cited and their statements on blue economy. Analysis reveals no sustained coverage, little that communicated with a national audience, little investigative reporting, and no predominance of London-based newspapers in news production. Reporting on blue economy was sporadic until a surge in 2020 that coincided with efforts to secure investments through local growth plans. Newspapers registered this buzz of activity, collecting statements from actors who used business ethics to express the legitimacy of their planning to build what they called a ‘blue economy’ even though this looked more like ‘blue growth’. A second group of actors including the Scottish Government announced plans to build a ‘sustainable blue economy’. These actors used the ethics of regional development, achieving net zero and protecting, enhancing or restoring ocean environments. Journalists reported critical views on these plans: inadequate attention to environmental protection, investment in activities seen as environmentally unsustainable or investments with limited regional development. Thus, analysis of statements on ‘blue economy’ reveals a discursive field featuring a confusion of contested ethical claims. This paper identifies the UK’s fragmented newspaper landscape and new architecture of public–private enterprise partnerships as important contexts shaping media engagement with blue economy.
