This article reports on the 21st Conference of Parties (COP) of the United Nations Framework Convention on Climate Change (UNFCCC), held 30 November-12 December, 2015, in Paris, France. After providing an overview of the primary outcome of COP21, the Paris Agreement, this report explores the intersection between the Antarctic Treaty System and the UNFCCC. There is little overlap between the two institutions, causing a climate policy gap between Antarctica and the rest of the world. This paper concludes with recommendations to narrow this gap.
