In its Advisory Opinion No. 32 (OC-32) on the climate emergency and human rights, the Inter-American Court of Human Rights will establish concrete obligations for governments across the continent to effectively protect people affected by the climate crisis. This will mark the first time a regional human rights court issues such a pronouncement. Learn how this decision will protect vulnerable communities and guide decisions made by national and international courts. 

What Are Advisory Opinions of the Inter-American Court? 

Advisory Opinions are authoritative interpretations of a legal provision or issue, intended to help States understand and fulfill their obligations under the American Convention on Human Rights and other relevant international instruments.

These Opinions are important because they establish the proper interpretation of human rights norms, guiding States on how to uphold and implement them within their territories or jurisdictions.

The Inter-American Court issues Advisory Opinions at the request of member countries of the Organization of American States (OAS) or certain affiliated bodies. 

What Is Advisory Opinion No. 32 on the Climate Emergency and Human Rights? 

In a historic step forward for climate justice, the Inter-American Court of Human Rights will issue an Advisory Opinion in response to a request made by the governments of Colombia and Chile. This Opinion will clearly define the obligations of States across the Americas to protect human rights in the face of the climate crisis.

In their request, Colombia and Chile emphasized the disproportionate impacts of climate change on countries in the Global South—those least responsible for the crisis—and particularly on communities in situations of vulnerability due to factors such as geography, climate, socio-economic status, gender, age, and race. 

Advisory Opinion No. 32 (OC-32) will address the obligations of States to: 

• Protect and uphold human rights in the context of the climate emergency.
• Preserve the right to life and survival based on the best available scientific knowledge.
• Safeguard children and future generations.
• Ensure access to effective legal remedies, protection, and reparation for climate-related harms.
• Protect human rights defenders, women, Indigenous Peoples, and Afro-descendant communities.
• Guarantee the right to a healthy environment in the context of the climate emergency.
• Uphold the principle of Common but Differentiated Responsibilities and Respective Capabilities. 

Like other Advisory Opinions issued by the Inter-American Court, the decision will carry legal weight and authoritative interpretive value for all OAS member states. 

It will serve as a vital tool for guiding decisions by judges and other justice system actors. Additionally, it will provide a clearer and more robust legal framework for individuals, communities, organizations, and authorities working to defend the environment and human rights amid the climate crisis. 

A Turning Point for Climate Justice 

Advisory Opinion No. 32 (OC-32) from the Inter-American Court of Human Rights marks a decisive moment for climate justice in Latin America and beyond. For the first time, a regional human rights court will directly clarify the obligations of States in the Americas to address the climate emergency as a human rights issue.

This decision goes beyond the legal realm—it is a concrete tool for transformation, representing: 

• Clarity on State Obligations

With the OC-32, the Inter-American Court will clarify the legal duties of Latin American States to address the climate crisis as a matter of human rights. This may require States to acknowledge their responsibility to reduce greenhouse gas emissions, support adaptation measures, and establish mechanisms to address loss and damage.

• New Legal Standards for the Region

The decision will set legal standards that governments across the continent must meet to protect human rights in the face of the climate crisis. These standards will shape a legal framework that can influence decisions by national and international courts, climate negotiations, public policy, and advocacy efforts worldwide.

• Strengthening of Climate Litigation

By providing authoritative interpretations of human rights treaties adopted by States in the region, it will offer strong legal arguments to support judicial rulings holding governments, corporations, and other actors accountable for the causes and consequences of the climate crisis—thereby strengthening the growing global movement for climate litigation.

• Recognition of Specific Vulnerabilities

The OC-32 will enable greater recognition and visibility of how the climate crisis disproportionately impacts Indigenous Peoples, women, children, and other vulnerable groups. It will establish differentiated State obligations to protect them, marking a key step toward safeguarding the rights of present and future generations. 

• Momentum for the Climate Justice Movement

The OC-32 comes at a critical moment, as the climate justice movement in Latin America and around the world gains momentum through successful strategic litigation and innovative legal precedents. It will reinforce the understanding that climate action by States is a legal obligation—not a voluntary commitment—in the eyes of international courts.

This decision by the Court is not merely a legal interpretation—it is a declaration that protecting the climate means protecting life, dignity, and the future of the region. 

Voices from the Frontlines: Impacts and Proposals Rooted in Local Knowledge 

At a historic moment for climate justice, the voices of the communities most affected by the climate crisis were heard directly by the judges of the Inter-American Court of Human Rights.

This marks a significant milestone in participation and access to justice: people who face the consequences of the climate emergency every day spoke before the region’s highest human rights court, sharing how the climate crisis and environmental injustice are affecting their ways of life—and what they propose the Court should do to help uphold their rights amid this global crisis and the actions taken to confront it. 

Why is this participation so important? 

The climate crisis is not an abstract problem. It is the river that dries up, leaving entire communities without water. It is the flood that destroys ancestral crops. It is the rising sea level that forces families to leave their territories. It is the extreme temperatures that threaten the health of children and the elderly.

Only those who live these realities can truly explain how the climate emergency violates fundamental rights such as life, health, food, territory, and culture.

The Inter-American Court needed to hear these voices to understand that protecting the climate is not merely an environmental duty—it is an urgent human rights obligation, with names, faces, and homelands behind it. 

AIDA’s Role in This Historic Decision 

From the outset of the process, AIDA has played a proactive role, amplifying the participation of communities in Latin America affected by the climate crisis: 

• We supported various communities across the region to ensure their voices were heard by the Inter-American Court through the submission of legal briefs highlighting the socio-environmental impacts of the climate emergency on Indigenous Peoples, women, children, and people of diverse gender identities and orientations.

• We accompanied community representatives in participating in the hearings held in April and May 2024, in Barbados and Brazil, respectively. 

  Hear their testimonies

• We submitted our own legal brief to the Inter-American Court, arguing that the right to a “stable and safe climate” should be recognized as part of the universal right to a healthy environment, and emphasizing States’ obligations to prevent and mitigate the harmful effects of the climate emergency on their populations.
