On 5 November, 2025 Camilla Pollera, Human Rights and Climate Change Program Associate at the Center for International Environmental Law published a blog post about the upcoming COP30 and the role of human rights defenders:
There is no climate justice in a climate of fear. As governments prepare to meet in Belém, Brazil for, COP30, attention turns to a country where defending nature still comes at a high cost. Deep-rooted and intertwined impunity and violence against environmental human rights defenders (EHRDs) — including Indigenous defenders, Afro-descendent communities, women, and defenders from LGBTQIA+ —persist in Brazil.
COP30 decisions must recognize the efforts of those protecting the planet, in Brazil and beyond, and ensure that they can do so safely, freely, and without fear.
Around the world, EHRDs are on the frontlines of the climate crisis — protecting land, water, communities, and their rights, often at great personal risk. Faced with an escalating climate crisis and the inaction of governments, a growing number of people are stepping up to defend their rights, the rights of future generations and the right to a clean, healthy and sustainable environment, exercising their fundamental freedoms of expression, peaceful assembly, and association, guaranteed under international human rights law.
…The violence and repression faced by defenders are intensified by intersecting forms of marginalization, especially affecting women defending the environment, who often suffer gender-based violence that rarely appears in the data, including sexual violence, harassment, and rejection within their families and communities. They are targeted not only as defenders of rights and natural resources but also as women, in all their diversity, challenging discriminatory societal norms, a combination that makes their work particularly dangerous and invisible. …The persistent violence and lack of effective guarantees for human rights protection are a stark reminder of what is at stake as COP30 comes to Belém.
The Advisory Opinion of the Inter-American Court of Human Rights on the climate emergency and human rights made it clear: States must take proactive steps to ensure the effective protection of environmental defenders — including for those such as Indigenous and women EHRDs who are most at risk of retaliation. The Court recognized EHRDs are “allies of democracy”, whose work takes on even greater importance amid the urgency and complexity of the climate emergency. It reaffirmed the right to defend human rights as an autonomous right and declared that States have a special duty of protection toward those who exercise it, and recognized the double layer of risk faced by women environmental defenders, requiring an even higher duty of care. The Court also formulated very concrete recommendations on what this means at the national level.
The Escazú Agreement and the Aarhus Convention both enshrine explicit provisions on the protection of EHRDs, setting legal and institutional frameworks to operationalize these duties. Recent work under these instruments has provided concrete guidance for States and businesses to uphold their obligations, safeguard civic space, and ensure defenders are protected and not penalized. The recent Action Plan under Escazú and the ad hoc rapid response mechanism under Aarhus are just a few examples marking concrete advances in protecting those facing threats.
At COP30, Parties can no longer ignore their human rights obligations. They have a duty to ensure that the UN Framework Convention on Climate Change (UNFCCC)—the central forum for global cooperation on climate action—and its outcomes align with legal standards. Rightsholders have been obstructed from participating and silenced the climate talks, a process that is deciding on their future. Restrictions on the rights to freedom of expression and assembly, lack of transparency in the host country agreements, persistent visa barriers and financial burdens, continue to limit access. In recent COPs, civic space has continued to shrink, with obstruction often led by the very States hosting the negotiations.
Brazil has a chance to do things differently, by making civic space at COP30 and the protection of environmental defenders a true priority. This includes guaranteeing safe conditions for the meaningful participation before, during, and after COP30 and beyond. And it also means taking steps domestically, starting with the urgent ratification of the Escazú Agreement. Brazil has a key role to play in building upon its legacy of international environmental leadership and steering negotiations at the COP towards rights-based outcomes.
COP30 indeed offers a crucial moment to enhance the protection of defenders through critical decisions expected in Belém: the Just Transition Work Programme (JTWP) and the Gender Action Plan (GAP).
As highlighted by the recent report of the UN Special Rapporteur on Human Rights Defenders, Mary Lawlor, a just transition should be grounded in the protection of those who defend rights and call out false climate solutions, from Indigenous Peoples and land defenders opposing harmful mining projects to workers’ advocates demanding fair and equitable transitions. All decisions, measures, and mechanisms designed to enable a just transition from the fossil fuel economy must protect a safe and enabling civic space, and ensure the meaningful participation of EHRDs.
..
There is no climate justice without human rights and without protecting those on the frontlines. EHRDs step in to protect what governments have neglected, and their courage exposes States’ failure to meet their climate and human rights obligations. Despite the risk, around the world, defenders continue to organize, resist, and demand climate justice, leading the way forward. In their resistance lies the chance of a just and sustainable future.

On 5 November 2025 Amnesty international endorsed this kind of view under the title “What is COP and why is this year’s meeting in Brazil so important?”
