Unlocking the IACtHR Advisory Opinion on Climate Change: Key Insights and Implications for Our Planet

On July 3, 2025, the Inter-American Court of Human Rights (IACtHR) made a significant move by addressing climate change in the context of human rights. This advisory opinion sets new legal standards for how countries should act in the face of the climate crisis.

The court emphasized that the urgent climate emergency requires immediate action that prioritizes human rights. They stated: “This climate emergency can only be adequately addressed through urgent and effective actions, articulated with a human rights perspective.” This reflects a growing recognition that protecting the environment is directly linked to safeguarding human rights.

A New Legal Framework

A key aspect of the IACtHR’s opinion is its declaration that preventing irreversible harm to the environment is a “jus cogens” norm—a fundamental principle of international law. This means that all countries must adhere to it, akin to prohibitions against torture or genocide. It marks a shift in how we view environmental protection, now seen as an essential part of human rights.

This perspective draws from the “human rights-environment nexus,” highlighting the connection between a healthy environment and the ability to enjoy basic rights, like life and health. Governments are now urged to adopt climate measures that not only mitigate climate change but also protect vulnerable populations. Groups like Indigenous peoples and low-income communities are disproportionately affected by climate impacts, making it crucial for climate policies to focus on their needs.

The Principle of Climate Justice

The IACtHR identified that certain marginalized communities face the brunt of climate change impacts. This insight reminds us that climate action should prioritize those who are often left out of discussions, ensuring their voices are heard and their rights protected.

For example, Indigenous-led conservation efforts have shown great promise in biodiversity and resilience, blending local knowledge with modern science.

Recognizing a Right to a Healthy Climate

The court also took a major step by recognizing the right to a healthy climate as a distinct legal right. This framework allows individuals and courts to pursue climate action more effectively, without solely relying on general environmental laws.

This change comes in response to the fact that climate change is a unique challenge requiring specific legal protections. The judges noted that damage to climate systems is distinct from broader environmental issues like pollution, necessitating tailored legal frameworks to safeguard these systems.

Demand for Timely Action

Addressing the climate crisis calls for swift and effective actions. The court pointed out the alarming “emissions gap.” According to recent data from the United Nations Environment Programme, if current policies continue, there’s a significant chance global temperatures will rise dangerously high.

The concept of resilience is vital here. The Intergovernmental Panel on Climate Change (IPCC) emphasizes the importance of combining adaptation with robust institutions for sustainable development.

Nature’s Rights

In a notable decision, the court recognized nature as a rights-bearing entity. This challenges the conventional view of nature merely as property, establishing it as deserving protection under human rights law.

Conclusion

Christiana Figueres, a key figure in global climate policy, described the court’s opinion as redefining climate action as a human rights obligation. While advisory opinions like this aren’t legally binding, they shape legal principles and influence domestic courts.

As the world grapples with climate change, this landmark opinion presents a roadmap for a rights-based approach to climate justice that addresses the needs of the most vulnerable.
