The term “green growth” and its sister concepts, “blue‐ green growth,” the “green economy,” and the “blue‐ green economy,” have gained considerable traction in the Pacific island region in a short space of time. Pacific island governments, regional organisations, and development agencies all use the terms, which originate outside of the Pacific. What (and who) has driven the adoption of green growth terminology within the region? How has its usage in the region mirrored international usage? This paper presents findings from research on the vernacularisation of green growth terminology in Fiji and Vanuatu. We find a contested policy space, where Pacific actors deploy competing meanings of green growth terms in ways that both reflect their worldviews and support their agendas. This diversity has helped to underpin the rapid spread of green growth terminology in the region, while differentiating it from international usage.
