As vulnerable clustering of small islands nations within the vast Pacific Ocean, the Pacific Island Countries (PICs) are faced with urgent environmental problems nowadays. It's important to evaluate their current sustainability performances and seek systematic resolutions for their sustainable development. This paper tried to apply the Sustainability Assessment Fuzzy Evaluation model to assess the overall sustainability performances of 11 selected states from 2005 to 2016. The initial results showed that most of the countries were at the intermediate and fairly high-level sustainability status. A ranking of 11 selected countries according to their overall sustainability index showed that Palau was the one with the highest level, while Solomon Islands were the lowest in sustainability performance. Energy use, terrestrial protected areas, and political rights issues are among major factors that influence the sustainability of the PICs.
