Abstract
Natural climate variations have existed for thousands of years, but since the industrial revolution and particularly after World War II, anthropogenic climate change has gradually emerged due to the availability of cheap fossil fuels (coal, oil, and natural gas) and the dramatic rise in their consumption, especially in industrialized countries. Although historical and current global emissions of GHG have originated in developed countries, the negative effects of climate change have been unevenly and disproportionally visited upon mostly developing countries. Apparently, those who have generally contributed the least to anthropogenic climate change bear the most harm and responsibility stemming from its effects (i.e. managing climate-related human mobility, with the least capacity). However, international environmental law recognizes that those who contributed most to causing the harm bear both legal and moral obligations for mitigating it. The debate on shifting burdens for climate change pivots predominantly around three established principles of customary international law— the polluter pays principle, the principle of no-harm, and the principle of ‘common but differentiated responsibilities and respective capabilities’ (CDBR&RC). In this context, this chapter explores the responsibilities of the countries under international environmental law to provide compensation and assistance to the people displaced because of climate change and examine if the loss and damage mechanism within the Paris Agreement is an appropriate forum to ensure adequate compensation and assistance.
