Environmental displacement: Can the European Union turn recognition into protection?

Human mobility encompasses different forms of movement, including voluntary migration and forced displacement. This piece focuses specifically on cross-border environmental displacement: situations in which environmental harm materially constrains people's ability to remain in their habitual residence and forces them to leave home and cross an international border. The EU's migration and asylum framework still lacks a dedicated legal pathway addressing this form of displacement.

Environmental degradation, driven in large part by climate change, is increasingly reshaping where and how people are able to live. Rising sea levels, floods, droughts, extreme heat, and the deterioration of livelihoods can gradually erode the conditions needed to remain in a given place. For example, in South Sudan, prolonged flooding displaced nearly 375,600 people in 2025, with some communities facing repeated displacement as floodwaters submerged homes and farmland.

This pattern of repeated, climate-driven displacement underscores the importance of adaptation and resilience, a priority of COP31, particularly its focus on strengthening the resilience of vulnerable countries and communities to climate risks. However, resilience measures alone cannot address the protection needs of people who are forced to cross international borders when environmental conditions make it increasingly difficult or impossible to remain in or return to their homes.

More broadly, environmental degradation is not limited to climate-related events. It also results from land degradation, resource depletion, and other forms of human activity, making continued residence increasingly difficult and, in some cases, impossible. When such circumstances compel people to leave home and cross an international border, the question arises: Does EU law offer them protection?

Environmental displacement and the EU legal gap

Environmentally displaced persons (EDPs) are people whose displacement is significantly linked to environmental factors. EDP is an analytical concept rather than an established legal category, as there is no internationally agreed-upon terminology for people who move in response to environmental factors. The primary concern regards EDPs who cross an international border and may require protection under EU law.

EU law does not currently provide a dedicated protection status specifically addressing environmental displacement. Under EU asylum law, refugee status requires a well-founded fear of persecution for reasons recognised under the 1951 Refugee Convention, while subsidiary protection covers people who do not qualify as refugees but face defined forms of serious harm. On its own, environmental damage isn't enough to qualify someone for international protection.

That said, existing international refugee law, human rights law, and relevant provisions of EU asylum law may protect some EDPs, depending on individual circumstances. Environmental degradation may interact with persecution or other forms of serious harm, while Article 4 of the EU Charter of Fundamental Rights may preclude return to origin countries in which there is a real risk of inhuman or degrading treatment. However, such case-specific protection does not establish a harmonised EU approach to cross-border displacement caused by environmental degradation.

This is not because the EU is unaware of the relationship between environmental degradation and displacement. EU policies increasingly recognise the links between environmental and climate-related pressures and human mobility through their climate adaptation policies, migration strategies, and international cooperation frameworks. What remains missing is the translation of this policy recognition into a clear and enforceable legal framework for EDPs. This distinction matters. Recognising a phenomenon is not the same as creating a legal entitlement.

Recognition has moved faster than protection

The gap between recognition and protection becomes clearer when EU policy and legislation are considered together. Although EU policies increasingly acknowledge the links between environmental pressures and human mobility, the Common European Asylum System continues to rely on legal categories that do not specifically address cross-border displacement linked to environmental factors.

The EU’s Pact on Migration and Asylum, which entered into application in June 2026, represents a major reform of the common migration and asylum system. It establishes common rules on screening, asylum procedures, responsibility, and solidarity. Yet, it does not create a dedicated EU protection status for people displaced across borders by environmental degradation.

This omission matters because environmental displacement does not necessarily take the form of a sudden, short-term mass influx. Environmental degradation may instead unfold gradually through recurrent flooding, sea-level rise, desertification, and prolonged heat. These processes can progressively undermine the conditions necessary for individuals to remain in a given place, raising questions about whether their circumstances are covered by conventional asylum procedures and emergency protection mechanisms. In some cases, environmental degradation may eventually make return physically or practically unviable for the individual concerned, irrespective of whether they retain a legal right to return to their place of origin.

The Temporary Protection Directive illustrates the limitations of existing mechanisms. While it provides for temporary protection in situations of mass influx, it does not establish a general protection mechanism for EDPs, particularly in contexts in which displacement develops gradually or persists over time. Its existence, therefore, does not resolve the broader legal gap.

A gap between displacement and protection

The absence of a dedicated framework also creates a problem of legal coherence. Without common rules, people affected by comparable forms of environmental degradation may have different prospects, depending on how existing legal categories are interpreted and applied by national authorities. Protection may consequently depend on fragmented approaches rather than common EU standards.

The gap also raises questions that cannot be answered solely at the point of admission. If EDPs are admitted, what residence rights should they receive? Should they have access to employment and social protection? How should family unity be protected? What should happen when return is no longer safe or realistically possible? And how should the financial and administrative responsibilities associated with protection be distributed between member states? These are not simply questions of humanitarian discretion. They are questions of legal design and institutional responsibility.

The problem, therefore, is not only the absence of a particular status. It is also the absence of a framework connecting eligibility, admission, protection, rights, and responsibility. A coherent response needs to address these elements together rather than treating admission as an isolated measure.

EU law already provides room for action

The absence of a dedicated status does not mean that the EU lacks the legal capacity to respond. Articles 77 to 80 of the Treaty on the Functioning of the European Union provide relevant foundations for EU action on border management, asylum, immigration, and solidarity. Article 78 concerns the common policy on asylum, subsidiary protection, and temporary protection; Article 79 addresses immigration policy; and Article 80 establishes the principle of solidarity and fair sharing of responsibility, including its financial implications, among member states. The precise legal basis for a new instrument would, however, depend on its objectives, scope, and design.

The EU could explore a framework that combines common eligibility criteria with appropriate admission and residence arrangements, access to employment and basic services, safeguards for family unity, humanitarian admission, and mechanisms for sharing responsibilities among member states. Depending on the circumstances and the applicable legal basis, measures could also include temporary protection and safeguards against removal in cases where return would expose a person to a real risk of serious harm. Such a framework would need to account for the diversity of environmental displacement, including situations in which environmental degradation interacts with other causes of displacement or progressively undermines the viability of return.

These measures would need to comply with EU competences, fundamental rights, and existing international obligations. They would not require treating everyone affected by environmental degradation as a refugee or assuming that all EDPs face the same protection needs. Rather, the objective would be to complement existing refugee protection mechanisms by addressing circumstances that may give rise to significant protection needs without necessarily meeting the criteria for refugee status or another established form of protection.

From recognition to legal protection

The EU has increasingly recognised that environmental and climate-related pressures can affect human mobility. The challenge now is to translate that recognition into a coherent legal response. Creating a new category of ‘climate refugees’ would neither capture the full range of environmental degradation nor reflect the different circumstances under which displacement occurs. Equally, relying exclusively on existing asylum and human rights frameworks does not provide a general, predictable response to cross-border displacement linked to environmental harm.

A dedicated EU framework for EDPs could address this gap by establishing appropriate criteria and protection arrangements for people whose ability to remain in, or return to, their homes has been materially undermined by environmental degradation. It would complement, rather than replace, existing refugee protection and would distinguish between different levels and types of protection need.

The question, ultimately, is whether the EU is prepared to translate its growing recognition of environmental displacement into a legal response proportionate to its consequences.
