The Paris Agreement requires that signatories develop and communicate their post 2020 climate actions in the form of Nationally Determined Contributions. This paper encompasses an overview of the nationally determined contributions communicated by the Pacific Small Islands Developing States with a focus on the four (4) Melanesian countries; Fiji, Papua New Guinea, Solomon Islands and Vanuatu. It identifies the gaps and challenges the nationally determined contributions potentially entail and is a contribution to the development of discourse on nationally determined contributions for the four (4) Melanesian countries. The methodology used is a situational analysis of the NDCs communicated by Fiji, Papua New Guinea, Solomon Islands and Vanuatu. The paper explores the questions ‘are the current nationally determined contributions communicated by the four (4) Melanesian countries consistent, comprehensive and feasible?’ and ‘what can be done to improve the information provided in these nationally determined contributions?’ The paper proposes key mitigation and adaptation interventions for NDC enhancement and is intended to be used by the four (4) countries to enhance the implementation of their nationally determined contributions
