In evaluating international treaties, in particular, the United Nations Framework on Climate Change Convention, this paper shows that necessary preparations have not been made to protect the rights of individuals who are refugees or have been forced to migrate from their homeland. Immigrants are deprived of the most essential human rights, such as language, culture, and having a right to a healthy living environment. The current legal administration has not made the necessary contingencies for responding to the environmental consequences of immigration and is extremely inefficient in expanding this phenomenon. This paper seeks to address the question of to what extent existing forms of legal and operational protection can apply in climate change-related displacement in general and cross-border displacement in particular. In this work some strategies have been proposed for dealing with these existing gaps. It is expected that analyzing these gaps and determining the international community’s duties and commitments (governments and international organizations) can result in efficient management of this crisis and prevent the outbreak of chaos across the globe.
