According to the 1951 United Nations Convention and Protocol Relating to the Status of Refugees, and the associated United Nations High Commissioner for Refugees, a refugee is defined as “someone who has been forced to flee his or her country because of persecution, war, or violence. A refugee has a well-founded fear of persecution for reasons of race, religion, nationality, political opinion or membership in a particular social group. Most likely, they cannot return home or are afraid to do so. War and ethnic, tribal and, religious violence are leading causes of refugees fleeing their countries.”
This is probably because the idea of climate refugees – people driven from their homes due to the effects of ever-increasing climate change, is relatively new. However, as the effects of climate change intensify, we will start to see more of an overlap between environmental law and immigration law – two areas that would otherwise rarely see the inside of the same courtroom.
Climate refugees are those people forced to flee their homes due to the negative effects of climate change. This could mean persistent drought that no longer sustains a family on their land, so it no longer makes sense to try and farm it or it could mean flooding that destroys entire neighbourhoods, driving people from their homes. In fact, the United Nations has statistics to show that this is already occurring: an average of more than 20 million people have been displaced by weather-related events each year since 2008. The general consensus among those who work on both climate change and refugee policy is that this is only going to get worse.
In fact, even the Paris Agreement includes three sections that discuss displacement and human mobility issues:
These are important concepts to recognize; however, classifying someone as a migrant does not afford them the same protections under international law as the designation of refugee. This is because international law and the UN’s Convention on Refugees work specifically to ensure that refugees are protected and that they are not immediately deported back to their country of origin.
Migrants, on the other hand, are subject to each individual country’s immigration laws – some of which may be more accommodating than others. Although the idea of human displacement due to climate change is relatively new, especially in comparison to the idea of forced displacement due to war, persecution, or other human forces, the underlying concept is the same – forced human relocation due to external factors.
Currently, there is still significant opposition to the conflation of the two types of refugees (environmental and traditional) including the argument that environmental refugees may still be able to rely on their national government while for traditional refugees, their national government is the source of their persecution. Unfortunately, the truth is that governments (provincial and/or state level or national level) are often complicit in encouraging industrial development and in implementing policies that have led to, or at least exacerbated, the negative effects of climate change. These types of policies could include encouraging people to build their homes on coasts threatened by rising sea levels, while also providing subsidies to fossil fuel companies as an example.
The concept of climate refugees is still new and currently nothing in international law has changed to accommodate those displaced from their homes by extreme climate events. However, with the ever-increasing rate of rising oceans, extreme weather and other effects of climate change (some of which you can read about in our case studies below) it is likely that the divide between environmental law and immigration/refugee law will lessen.
