A Historic Breakthrough for Climate Justice: The Inter-American Court Recognizes the Right to a Healthy Climate

On July 3, 2025, the Inter-American Court of Human Rights (IACHR) issued its Advisory Opinion 32/25, a historic and unprecedented milestone for environmental and human rights law. For the first time, a regional human rights court has explicitly recognized the autonomous right to a healthy climate—an essential, enforceable human right rooted in the urgency of the climate crisis. This decision sets a transformative legal precedent, shifting climate action from voluntary aspirations to binding obligations.

The Court underscored that States have legal duties, not merely policy preferences, to prevent climate harm. These duties include adopting reinforced due diligence measures for groups most affected by climate change, such as Indigenous peoples, children, women, older adults, people with disabilities, and environmental defenders. The right to a healthy climate is now framed as a distinct legal entitlement, reinforcing the need for intergenerational equity and accountability.

Under the American Convention and the Protocol of San Salvador, States must respect, guarantee, and cooperate in climate matters. They must avoid regressive actions, manage climate risks with scientific and human rights-based policies, and collaborate across borders to address shared environmental challenges. Equally crucial is the protection of procedural rights—ensuring access to information, public participation, and justice, particularly for collective and intergenerational claims.

The opinion also mandates a gender-sensitive and intersectional approach, acknowledging that women and girls—especially in rural and marginalized communities—bear disproportionate climate burdens. It calls for enhanced protection of environmental defenders, including Indigenous women, who face heightened risks like criminalization and gender-based violence.

OC-32 was developed through the most participatory advisory process in the Court’s history, with over 600 contributors and extensive public hearings across Latin America. It now serves as a legally binding interpretive tool for all OAS member states, reinforcing and expanding global climate jurisprudence.

Yet, while groundbreaking, OC-32 does not address all challenges. It falls short in fully regulating private sector emissions and lacks stronger judicial innovations like burden-shifting. Still, these limitations open the door for continued legal and civic advocacy.

As COP30 approaches in Latin America, Advisory Opinion 32 offers an extraordinary opportunity to push for inclusive, rights-based, and enforceable climate action. For KALLIED and the environmental defenders we support, this ruling is more than a legal victory—it is a call to action grounded in the lived realities and leadership of communities across the Global South.
