Climate Justice: Human Rights and Security in an Era of Climate Crisis

Climate change is not just an environmental problem. It is fundamentally a human rights and security crisis. As temperatures rise and extreme weather events intensify, the basic rights that underpin human dignity-access to water, food, shelter, and a healthy life-are being systematically undermined for millions of people worldwide. This intersection of climate impacts with human rights creates what we now recognize as a defining challenge of our era: climate justice.

How climate change threatens basic human rights 🔗

Climate change has a negative impact on the enjoyment of human rights, affecting everything from the right to life to rights concerning water, food, health, housing, culture, and development. The Intergovernmental Panel on Climate Change (IPCC) has unequivocally confirmed that climate change is real, driven primarily by human-made greenhouse gas emissions, and is causing widespread harm to both natural and human systems.

Consider what this means in practical terms. Rising sea levels threaten the very existence of low-lying coastal communities and small island nations. Prolonged droughts destroy agricultural livelihoods in arid regions. Arctic communities watch their traditional ways of life disappear as ice melts and permafrost thaws. These are not abstract scenarios-they are happening now, and they represent direct violations of fundamental human rights.

Disproportionate impacts on vulnerable populations 🔗

The impacts of climate change do not fall equally on all shoulders. Persons in vulnerable situations-whether due to geography, poverty, gender, age, indigenous or minority status, or disability-experience heightened exposure to climate-induced harm. People living in small island developing states, least developed countries, and regions facing water scarcity, desertification, and land degradation bear the heaviest burden.

Africa, despite contributing negligibly to global greenhouse gas emissions, stands as one of the most vulnerable continents to climate impacts. The region’s warming rate exceeds the global average, making drought a recurring phenomenon across East and Southern Africa. This stark inequity-where those least responsible suffer most-lies at the heart of climate justice concerns.

The Human Rights Council’s response 🔗

The United Nations Human Rights Council has worked systematically to illuminate the connections between human rights and climate change through resolutions, reports, and international dialogues. This institutional recognition represents a significant shift in how the international community approaches climate policy.

In 2011, the UNFCCC adopted the Cancun Agreements, which explicitly called on parties to respect human rights when taking climate action. This was an important first step, but the real watershed moment came four years later.

The Paris Agreement’s human rights commitment 🔗

The Paris Agreement in 2015 marked a turning point. Its preamble called on countries to respect and promote human rights in all climate actions-the first such reference in any multilateral environmental agreement. Specifically, the agreement acknowledges that parties should respect their obligations concerning human rights, the right to health, the rights of indigenous peoples, local communities, migrants, children, persons with disabilities, and people in vulnerable situations.

This language matters because it creates an overarching expectation that states will protect human rights when implementing climate policies. It establishes that climate action and human rights protection are not separate concerns but fundamentally interconnected obligations.

Understanding human security in the climate context 🔗

Traditional security thinking focuses on protecting nation-states from external military threats-guarding borders, maintaining territorial sovereignty, and defending against armed conflict. Human security represents a fundamentally different paradigm.

Human security means safety from chronic threats such as hunger, disease, and repression, as well as protection from sudden disruptions to daily life in homes, jobs, and communities. This broader concept emerged from the United Nations Development Programme’s 1994 Human Development Report, which argued that ensuring “freedom from want” and “freedom from fear” for all persons is the best path to tackling global insecurity.

Why the distinction matters for climate policy 🔗

Human security and traditional security differ fundamentally in their focus and objectives. While traditional security is state-centric and emphasizes military protection, human security is people-centric. It addresses root causes of insecurity including economic instability, health crises, environmental degradation, and violence.

This distinction has profound implications for climate policy. Climate change does not cause conflict directly; rather, it exacerbates existing vulnerabilities caused by governance failures and socioeconomic conditions. When we view climate change through a human security lens, we recognize that responses must address not just emissions but also the underlying conditions that make communities vulnerable.

Climate as a threat multiplier 🔗

Climate change is often called a threat multiplier because it intensifies resource scarcity and worsens existing social, economic, and environmental factors. Unpredictable rainfall and extreme weather trigger competition for food and water. Declining agricultural output leads to income losses for broad population segments. Droughts, floods, storms, and sea-level rise already force more than 20 million people annually to leave their homes.

The UN Human Security Unit emphasizes that the loss of land and livelihoods, against a backdrop of persistent poverty and displacement, can trigger competition for scarce natural resources and fuel social tensions. Countries most vulnerable to climate effects-including Yemen, Mali, Afghanistan, Democratic Republic of the Congo, and Somalia-often already struggle with conflict and political fragility.

The rights-based approach to climate action 🔗

A rights-based approach to climate change fundamentally reframes how we understand and respond to the crisis. Rather than treating climate change as a purely technical or environmental problem requiring engineering solutions, this approach emphasizes the human dimensions of climate change by focusing on impacts to individuals, communities, and peoples.

This perspective serves several crucial functions. It recognizes how systemic discrimination creates and exacerbates vulnerability. It focuses attention on social and environmental justice in climate governance. And it establishes that states and private actors have specific obligations to take effective mitigation and adaptation measures that respect, protect, and fulfil human rights.

Key principles of rights-based climate action 🔗

Within states, a rights-based approach addresses both underlying vulnerabilities and climate impacts through genuine implementation of non-discrimination and equality principles. These principles do not require identical support for all citizens. Instead, because marginalized and vulnerable groups already face compromised rights, states must take extra care to ensure their protection.

Researchers recommend several guiding principles for ethical and effective climate responses. These include equity, with inclusive strategies for vulnerable populations; justice, demanding accountability for historical emissions; the precautionary principle, advocating early protective action despite uncertainties; and shared but differentiated obligations, where developed countries lead in emission reductions while supporting vulnerable nations.

Legal momentum for climate rights 🔗

The legal landscape for climate rights has evolved dramatically. In 2024, the European Court of Human Rights recognized that insufficient climate action can constitute a human rights violation, following a landmark case brought by Swiss women against their government. The International Court of Justice has also affirmed that states have legal obligations under international human rights law to respect and ensure effective enjoyment of human rights by taking necessary measures to protect the climate system.

These judicial developments reinforce what advocates have long argued: the right to a stable climate is emerging as integral to existing human rights frameworks. In July 2022, the UN General Assembly declared access to a clean, healthy, and sustainable environment to be a universal human right, further solidifying this connection.

Concrete impacts across human security dimensions 🔗

Understanding climate justice requires examining how climate change manifests across different dimensions of human security.

Food and livelihood security 🔗

As the planet warms, longer and more intense droughts lead to soil erosion, dried-up grazing lands, and reduced crop yields. Floods and landslides destroy agricultural infrastructure. Water resources grow increasingly scarce. In regions like Mali and Somalia, these cumulative effects have undermined communities’ capacity to plan and sustain their livelihoods, exacerbating tensions between farming and herding communities.

Displacement and migration 🔗

Climate-induced displacement has become a defining feature of the current crisis. Each year, over 20 million people are forced to leave their homes due to extreme weather events including abnormally heavy rainfall, prolonged droughts, desertification, sea-level rise, and cyclones. Over the past decade, weather-related disasters have caused around 250 million internal displacements-more than 67,000 per day.

Gendered dimensions of climate insecurity 🔗

Pre-existing inequalities, gender-related roles, and unequal access to resources leave women and girls disproportionately vulnerable at the intersection of conflict and climate crisis. When women must travel further from home searching for water, they face increased risks of sexual violence. Climate disasters also correlate with rising rates of early marriage as families cope with livelihood insecurity.

Building a climate-just future 🔗

The IPCC has warned in its Sixth Assessment Report that temperature increases above 1.5°C compared to pre-industrial levels would lead to ecosystem collapse and jeopardize the livelihoods of millions, disproportionately affecting those already in vulnerable situations. Effectively addressing climate harm requires states to take meaningful measures to reduce emissions, tackle impacts, and address losses and damages-all grounded in human rights principles.

This means ensuring the safe and meaningful participation of affected communities, civil society, and Indigenous Peoples in policy decisions. It means recognizing that states have a human rights obligation to prevent foreseeable adverse climate effects and ensure that affected populations have access to effective remedies and adaptation support.

The framework is clear. Climate justice and equity principles recognize that impacts do not affect everyone equally and that the most vulnerable populations are often the most affected. Moving forward requires not just technical solutions but fundamental commitments to fairness, accountability, and human dignity in every climate decision we make.

What do you think? How might your community or nation better integrate human rights considerations into climate policies? And what responsibilities do wealthier nations have toward countries bearing the greatest climate burdens despite contributing least to the problem?
