ABSTRACT
Antarctica and the Arctic often regarded as polar regions located at the south and north poles respectively plays an important role of sunlight reflection in the climatic system. Such geo-metrological function of the polar regions ensures the maintenance of balance on planet earth hence the need for protection of the regions as global commons. Thus, the focus of this paper is to x-ray the rationale behind the differential approach in environmental protection of both regions by adopting an interdisciplinary approach which will give insight in the politico-legal regimes governing the regions. It will equally highlight why the Antarctic mechanism seems more systematic in relation to the Arctic regimes on environmental protection. It will conclude by advancing a proposition that will favour the desirability for more sustainable commitments on the part of state parties especially the Arctic States and the need for more state participation in governance of the regions.
