10 environmental news stories to end 2025 on a hopeful note

We are nearing the end of a complex year, and taking stock seems daunting. Multilateralism is faltering as environmental crises worsen and urgently demand decisive action.In such turbulent times, it is worth taking stock of what we, as humanity, have achieved in building a more just and sustainable world for all who inhabit it.2025 will be remembered as the year when an underwater expedition thrilled us in real time, when we celebrated the implementation of agreements to protect life in the ocean, and when international court rulings transformed the pursuit of justice to protect people and the environment from the climate emergency.These are some of the environmental victories that this year has left us with, and they deserve to be celebrated, just as we honor the fire that shines in the darkness. Because even with small lights, we can continue to illuminate a path of hope toward environmental and climate justice. 1. International courts issued landmark decisions for climate justiceThe Inter-American Court of Human Rights and the International Court of Justice released their respective advisory opinions on the climate emergency. Both decisions clarified the obligations of states to protect the rights of people and nature in the face of the climate crisis.These decisions are part of an unprecedented global movement for climate justice, which also includes the advisory opinion issued in 2024 by the International Tribunal for the Law of the Sea and similar future decisions, such as the one expected from the African Court on Human and Peoples' Rights.Learn More: Dialogue Earth 2. Climate litigation exceeded 3,000 cases worldwideClimate litigation reached 3,099 cases worldwide, according to a report by the Sabin Center for Climate Change Law and the United Nations Environment Program. Although climate litigation in countries in the global south is still in the minority (9.8% of the total documented), it has grown steadily. Brazil stands out as the third country with the most cases in the world (135), and other Latin American countries (Mexico, Colombia, Argentina, and Chile) are among the top 15 with the most cases reported.This growth demonstrates the increasing use of strategic litigation to promote concrete action on the causes and consequences of the climate crisis.Learn More: Sabin Center for Climate Change Law 3. Colombia declared its part of the Amazon free from oil and large-scale mining activitiesDuring the 30th UN Climate Change Conference (COP30), Colombia declared the entire Colombian Amazon region a zone free from oil and large-scale mining activities, announcing it as a "reserve zone for renewable natural resources."The decision implies an unprecedented limitation on the expansion of mining and hydrocarbon activities in more than 48 million hectares, equivalent to 7% of the entire Amazon region. It is also a call to other Amazonian countries to follow suit.Learn More: InfoAmazonia 4. Countries create a global mechanism to promote a just energy transitionAn important step forward at COP30 was the adoption of the Belém Action Mechanism, created within the framework of the Just Transition Work Program.The mechanism will function as a coordinating space to centralize global initiatives, offer technical assistance, and strengthen international cooperation. It is an achievement driven by civil society to promote ambitious climate action and a transition that does not repeat the mistakes of the fossil fuel era.Learn More: AIDA and The Climate Reality Project América Latina 5. An underwater expedition in Argentina marked a scientific and technological milestoneThe expedition "Underwater Odel Plata Canyon: Talud Continental IV," led by scientists from Argentina's National Scientific and Technical Research Council, in collaboration with the Schmidt Ocean Institute, explored the deep ocean in the Mar del Plata submarine canyon for 21 days, while broadcasting live on YouTube and Twitch.The result: 40 new marine species and an unexpected diversity of cold-water corals were discovered, findings that were seen and celebrated in real time by millions of people.Learn More: CONICET 6. The High Seas Treaty will finally enter into forceIn a process that took more than two decades, the High Seas Treaty this year reached the 60 ratifications needed to trigger its entry into force, which will occur on January 17, 2026. This binding agreement allows for the protection of the part of the ocean outside of national boundaries, almost half of the planet, through the creation of marine protected areas in international waters and the conduct of environmental impact assessments of planned human activities on the high seas. This is a historic milestone for the protection of the ocean and the well-being of millions of people in Latin America and around the world.Learn More: AIDA 7. Implementation begins on agreement ending harmful fisheries subsidiesThe World Trade Organization's Agreement on Fisheries Subsidies came into force in September this year. It is the first multilateral trade treaty to prioritize environmental sustainability, as well as a milestone in ensuring food security and the livelihoods of coastal communities.The agreement prohibits government subsidies that promote illegal fishing and the depletion of overexploited stocks.Learn More: WTO 8. Green sea turtles are no longer considered an endangered speciesAfter decades of decline, the population of green sea turtles is recovering. The International Union for Conservation of Nature no longer considers them endangered and has reclassified them as a "species of least concern."This sea turtle population has increased thanks to decades of conservation work to protect nesting areas, reduce capture, and prevent bycatch. AIDA was part of these efforts, protecting them in the 1990s from hunting—which was legal at the time—in Costa Rica.Learn More: AIDA and IUCN Red List 9. Protection of key ecosystems around the world, including the Galapagos, is growingUNESCO added 26 new biosphere reserves in 21 countries, the highest number in 20 years, and approved the expansion of 60,000 square kilometers in the Galapagos Biosphere Reserve in Ecuador to incorporate the Hermandad Marine Reserve. This will protect the area where dozens of marine species, many of them protected, transit, and which is considered one of the most diverse ocean corridors in the world.Learn More: LaderaSur and Government of Ecuador 10. Deforestation decreased in Afro-descendant territories in Latin AmericaAfro-descendant communities in Brazil, Colombia, Ecuador, and Suriname have significantly reduced their deforestation rates, according to new research from Conservation International.The study showed that Afro-descendant communities are critical to environmental conservation, as 56% of their lands are located in the 5% of the world with the highest biodiversity.Learn More: Conservation International

Our Contribution to Environmental Justice in 2025

At AIDA, one of our core pillars is using the law strategically — backed by science and international advocacy — to set important precedents that protect the environment and human rights across Latin America.This year, our work helped strengthen both regional and global legal frameworks so they can better respond to the social and environmental challenges we face today.These advances led to the creation of key legal tools that open new opportunities to defend communities and their territories, protect the region’s biodiversity, and hold governments and companies accountable.The progress we saw in 2025 highlights the transformative power of law, science, and the collective strength of communities when they work together. 1. Two new global treaties restore hope for the ocean — and for all of usThis year brought two historic achievements that could change the future of the ocean, and our own.The first is the ratification of the High Seas Treaty, which will take effect in January 2026. This legally binding agreement creates shared rules and a system of multilateral governance for the ocean areas beyond national jurisdiction — nearly half the planet.The second milestone is the entry into force of the World Trade Organization’s Agreement on Fisheries Subsidies. For the first time, a multilateral trade treaty puts environmental sustainability front and center by banning government subsidies that fuel illegal fishing and the depletion of overfished stocks.AIDA played an important role in ensuring Latin America’s perspectives were reflected in both agreements. We provided technical support to government representatives throughout the process, and we continue working to make sure these treaties lead to real, effective action across the region.Learn More 2. Maya community in Guatemala achieves a landmark environmental victoryIn Chinautla, Guatemala, the Poqomam Maya community won an unprecedented court ruling over decades of river pollution that violated their rights. The court ordered the municipality to carry out studies, programs, and plans to reduce pollution — and to ensure the community is involved every step of the way.This is the first time a court in Guatemala has recognized both a people’s right to a healthy environment and their central role in finding solutions. The ruling could inspire other municipalities along the Motagua River, the country’s longest river, where pollution also threatens the Mesoamerican Reef.Beyond providing legal support, AIDA helped the community document illegal dumping that harmed their water sources. This hands-on “community science” effort played a crucial role in both the lawsuit and the historic ruling.Learn More 3. Corte Interamericana marca un antes y después para la justicia climáticaOn July 3, the Inter-American Court of Human Rights issued its long-awaited Advisory Opinion 32 on human rights and the climate emergency — a landmark moment for climate justice both regionally and globally. The Court clarifies the legal obligations of states to protect people and communities affected by the climate crisis, opening new pathways for justice in national and international courts, climate negotiations, and public policy advocacy.For the first time, the Court recognized the right to a healthy climate and affirmed that states have a duty to prevent companies from violating human rights in the context of climate change.Ahead of this decision, AIDA helped amplify the voices of communities across the region, facilitating their testimony before the Court and presenting our own arguments for recognizing the right to a stable and safe climate.Learn More Discover the stories behind these victories and our full review of the year in our 2025 Annual Report.

Sesión Plenaria de los pueblos en la 30 Conferencia de la ONU sobre Cambio Climático en Brasil

November 25 2025 Climate Change, Human Rights, Indigenous Rights

COP30 ends — with a few achievements to move forward

With more than 25 hours of delay, the 30th UN Climate Change Conference (COP30) has come to an end. The so-called "Amazon COP," held in the Brazilian city of Belém do Pará, leaves behind disappointment for failing to change course, but also some advances that can help push climate action forward. It was not a total failure: multilateralism remains intact, though battered.COP30 was marked by the presence of Indigenous peoples, especially from the Amazon basin, who filled the streets and side events. However, according to reports, only a fraction of these delegations gained access to the formal negotiation rooms, while a disproportionate number of representatives from the fossil fuel industry participated in the official event. This imbalance reflects the democratic health of the climate regime: at the Amazon COP, the power of Indigenous and Afro-descendant peoples was felt in the streets, but their voices remained underrepresented in decision-making spaces.A few days into the conference, the latest synthesis report of updated nationally determined contributions was released. Its message was more bitter than sweet, but it offered one important takeaway: although the gap to keep global warming below 1.5°C remains enormous and complex, the report confirms that the Paris Agreement has indeed helped steer the challenge. We are in a better position than in a scenario without the agreement: projected emissions growth has been slowed, though not nearly enough.At this point, it is clear that COPs will not "save the world," but it also seems impossible to overcome this crisis without the cooperative platform they provide. From that perspective, it is worth asking what COP30 leaves us. The approved agreement: Global MutirãoThe word "Mutirão" references the spirit of collective effort—body and soul—that Brazil sought to bring to the international negotiation process at this COP.The approved agreement reiterates the goal of keeping the planet’s temperature increase below 1.5°C, acknowledging that time is running out. To that end, it proposes two voluntary mechanisms, led by the Presidency, which for now seem more like statements of good intent than tools with teeth: a "Global Implementation Accelerator" and the "Belém Mission for 1.5°C."On financing, the text establishes a two-year work program on Article 9.1 of the Paris Agreement, which concerns the public resources developed countries must provide, understood in the context of Article 9 as a whole.A footnote was added to clarify that this does not prejudge the implementation of the new global goal. Civil society organizations warn that this formulation risks further diluting developed countries’ specific obligations under the narrative of "all sources of financing," without clear rules on who must actually provide the resources and under what conditions. The real value of all this remains to be seen in practice. What was gained: A new mechanism for a just transitionA major achievement of COP30 was the adoption of the Belém Action Mechanism (BAM), a new institutional arrangement under the Just Transition Work Programme. It was the main banner carried by organized civil society.The mechanism is designed as a hub to centralize and coordinate just transition initiatives around the world, providing technical assistance and international cooperation to ensure the transition does not repeat the mistakes of the fossil era.The text incorporates many of the principles championed by Latin American civil society—including human rights, environmental and labor protections, free, prior and informed consent, and the inclusion of marginalized groups—as essential elements for achieving ambitious climate action.Even with gaps in safeguards and governance definitions, the BAM is a concrete step forward for this COP on climate justice. It creates a starting point to discuss not only whether there will be a transition, but how it will be done and under what rules, so as not to replicate the logic of the fossil economy. Its design and implementation will be debated at upcoming COPs, where it will be crucial for the region to arrive with solid, united proposals. Ending fossil fuels and deforestation: Two “almosts” that move us forwardAn agreement to leave behind fossil fuels and end deforestation—directly addressing the main drivers of the climate crisis—"almost" made it into the final decision.More than 80 countries from both the global north and south called for a roadmap to exit oil, gas, and coal. More than 90 supported a roadmap to stop and reverse deforestation by 2030. Although these requests made their way into drafts of the closing decision, they disappeared from the final text after resistance from major fossil fuel producers.Still, we do not leave empty-handed: Brazil, as COP30 Presidency, announced it will advance these roadmaps outside the formal framework of the UNFCCC. For the fossil fuel phaseout, Colombia committed to co-organize, with the Netherlands, the first global conference on the topic in April 2026.Although these items were not secured within the official negotiations, it is worth celebrating that—for the first time—such a broad coalition of countries united to achieve them. These two "almosts" matter: they set a new political and legal baseline for the rounds ahead. Two tools to advance adaptationCOP30 delivered tools to keep adaptation negotiations moving forward.The Mutirão decision calls for tripling collective adaptation finance by 2035, tied to the $300 billion USD per year agreed under the new global goal. This falls short of what the poorest countries asked for (tripling by 2030, with an explicit figure) and lacks clarity or guarantees regarding the role of developed countries. But it is a political anchor worth building on.At the same time, a first package of 59 indicators was adopted for the Global Goal on Adaptation (GGA). Several African countries and experts described them as "unclear, impossible to measure, and in many cases unusable," because they sacrifice precision and grounding in community realities in order to unblock the agreement. In response, the text included the "Belém–Addis Vision," a two-year window to correct flaws and make the framework operational by 2027.In short, we have more promises of money and an indicator framework weaker than necessary, but also a process through which the region can continue pushing for a useful GGA and for fair, sufficient adaptation finance. Loss and damage: Slow and uncertainProgress on this issue has been painfully slow compared with the urgency of the problem. At COP30, the third review of the Warsaw International Mechanism was finally approved. The result is frustrating: discussions have taken a decade while communities are already paying the cost of warming.On the other hand, the Loss and Damage Response Fund, created two years ago, issued its first call for proposals, with an initial package of $250 million USD in grants available over the next six months. The Fund has $790 million USD pledged, but only $397 million USD actually deposited—an enormous gap compared to the hundreds of billions estimated annually for developing countries.The expected political pressure for developed countries to scale up contributions was largely diluted in the final text, although the Fund was at least linked to the new global financing goal agreed at COP29. A new Gender Action PlanCOP30 concluded with the adoption of a new Gender Action Plan under the renewed Lima Work Programme. The Plan identifies five priority areas: capacity-building and knowledge; women’s participation and leadership; coherence among processes; gender-responsive implementation and means of implementation; and monitoring and reporting. It also provides a roadmap to ensure climate action is truly gender-responsive, with indicators to track progress. Methane: A super-pollutant still lacking the spotlight science demandsAt COP30, short-lived climate pollutants—especially methane—gained visibility thanks to a dedicated pavilion and dialogues with regional and global actors. The Global Methane Status Report 2025 was also presented, noting “significant” progress since the 2021 launch of the Global Methane Pledge. However, it warns that current progress remains far from the goal of reducing methane emissions by 30% by 2030.In the official negotiations, the draft of the Sharm el-Sheikh Mitigation Ambition and Implementation Work Programme included an explicit reference to methane mitigation through proper waste management, but that mention was removed from the final text, leaving only a general call to improve waste management and diminishing the focus on the urgent need to reduce emissions of a pollutant whose mitigation is essential to achieving the Paris Agreement goals. Still, during COP30, the global “No Organic Waste (NOW) Plan to Accelerate Solutions” was launched, aiming to reduce methane emissions from organic waste by 30% by 2030.Overall, this COP missed a crucial opportunity to advance its core objective. If we truly want to stay on track with the Paris Agreement, we must treat methane as what it is: a decisive opportunity we are still not seizing. How we close COP30 and prepare for the nextCOP31 will be held in Turkey, under the presidency of Australia. And despite the shortcomings of COP30, there are at least four things to defend and build on:The normalization of the debate on phasing out fossil fuels, with more than 80 countries openly calling for a roadmap and Colombia–Netherlands taking that discussion to a dedicated conference in 2026.A forest agenda that, although left out of the text, carries the promise of a Brazilian roadmap and explicit support from a wide group of countries.A small but real advance on adaptation, with the decision to triple finance and a first set of indicators that, while weak, offer a basis to push for improvements.The creation of a new mechanism for a just transition, which can shape how the transition unfolds—bringing together and strengthening efforts that support and protect workers, communities, and Indigenous peoples.

“Choose Europe”: Prioritizing minerals, not rights

The Raw Materials Week in Brussels, Belgium, has come to an end. This annual event, organized by the European Commission, aims to discuss how to ensure "sustainable and secure" access to raw materials in and for Europe, with the goal of strengthening international alliances to meet its defense, digitalization, and security goals.The European Commission emphasized that Europe is highly dependent on mineral imports from Latin America, which deepens the region’s historical pressures and the resulting need for stronger socio-environmental protections. However, from the Andean Wetlands Alliance, we maintain the week’s debates revealed an approach increasingly disconnected from human rights, community voices, and the global socio-environmental crisis.This shift in priorities is part of a broader political turn marked by geopolitical tensions around access to critical minerals and new energy sources, as well as by the rise of conservative forces and authoritarianism. A trend is emerging within the EU toward the privatization of human rights and environmental standards, along with the weakening of social and environmental safeguards through deregulatory processes. An example of this is the debate on the possible weakening of the Corporate Sustainability Due Diligence Directive.The dominant narrative this week was shaped by concepts such as “competitiveness” and “defense” as the guiding axes of European policies. Within the framework of a geopolitical rivalry between China and the United States, Europe seeks to reduce its dependence on its long-standing Western ally under the slogan “Choose Europe,” which titled this year’s edition. In this context, the European Commission continued to promote access to minerals through an approach centered on the security of its supply chains, without assessing its policies in light of planetary boundaries or human rights. This approach contradicts the commitments associated with the energy transition that originally motivated the discussions on “critical minerals.” Today, we ask to what extent the cost of “choosing Europe” will continue to be borne by local communities in Latin America and other peripheral regions affected by mining expansion.Today, we ask to what extent the cost of "choosing Europe" will continue to be borne by local communities in Latin America and in other peripheral regions affected by mining expansion.This edition had the least debate compared to the last years on the need to integrate human rights into European mineral policies. Indeed, accreditation for access to the official event was limited, and the forum's official agenda lacked a space for communities and civil society from the Global South to express their perspectives on mineral value chains like lithium, and to influence the debates that will shape the decisions affecting them. Instead, discussions focused primarily on investment opportunities for corporations and governments.From the Andean Wetlands Alliance, we highlight that the expansion of the extractive frontier contradicts the climate and biodiversity commitments endorsed by the EU and risks deepening existing asymmetries between the two regions. For this reason, we reaffirm our position on the need for a paradigm shift in EU raw materials policies, so that they become inclusive, transparent, and sustainable, ensuring the participation of communities and organizations located at the extractive frontier of transition minerals. Likewise, in the context of the ecological and democratic polycrisis, we stress the need for the EU to adopt concrete targets to effectively reduce mineral demand and to strengthen compliance with international human rights and environmental treaties.Press KitPress contactsVíctor Quintanilla, AIDA (regional), [email protected], +521 5570522107Rocío Wischñevsky, FARN (Argentina), [email protected], +541159518538Manuel Fontenla, Asamblea PUCARÁ (Argentina), [email protected], +54 9 3834790609Oscar Campanini, CEDIB (Bolivia), [email protected], +591 70344801Juan Francisco Donoso, Formando Rutas, [email protected], +4915780743628

Inauguración de la Conferencia de la ONU sobre cambio climático en la Amazonía brasileña

The home stretch of COP30: Shadows, contradictions, and some glimmers of hope

The first week is over, and the political phase of the 30th United Nations Climate Change Conference (COP30) has begun in Belém do Pará, Brazil. These are the days when decisions must be made.A COP had not been held in a country where public protest is possible since 2021 — and people have certainly made their voices heard. On Saturday, a massive demonstration took place: thousands demanded climate justice in the streets, to the rhythm of Amazonian drums. There was also a theatrical "funeral for fossil fuels," reminiscent of Tim Burton, with monsters and somber widows bidding farewell to an era that must be buried.But it has not all been carnival. Indigenous leaders blocked access to the event several times and even entered the "blue zone" — the restricted area — en masse, denouncing the exploitation of their territories. Their discontent is absolute. Although COP authorities met with the group, they soon sent a letter to the Brazilian government requesting increased security and the dispersal of protests. Human rights and environmental organizations have warned about the risks of criminalizing protest and the harmful message this sends about the role of Indigenous peoples.These protests reflect communities that ended up being a minority in an event that promised to be inclusive. There was also widespread criticism of the disproportionately large number of fossil fuel industry representatives involved in negotiations — a dynamic that makes the path toward climate justice even more complicated.Finally, advisory opinions (AOs) must not be left out of this review. While not formally on the agenda, they have made a strong impact. Their central message is powerful: international cooperation is not optional — it is a legal obligation. It is no surprise, then, that the theme keeps resurfacing: in side events, in constant references by civil society and some national delegations, and in cross-cutting mentions across debates on finance, adaptation, and transition. The AOs are not merely being cited; they are being embraced. Momentum is building to fully unleash their potential at this COP and beyond. Negotiations: Four key issues in “presidential consultations”The COP Presidency acted quickly with a novel approach: to adopt the agenda without delays, it set aside four complex issues and moved them into “presidential consultations.”Article 9.1 — Public Funding from Developed Countries. The debate centers on whether climate financing should come only from public sources or also from private sources, as well as on accountability and reporting standards. Developed nations — which are legally obligated to provide this financing — are resisting, while vulnerable countries urgently need the funds to survive the climate crisis.Unilateral Climate-Related Trade Measures. These include policies such as carbon border taxes. They are considered unfair or protectionist, especially by Global South countries with less capacity to reduce emissions. Negotiations aim to prevent arbitrary trade barriers while respecting climate action.NDCs and Ambition. According to the latest NDC synthesis report, there is a significant gap between current commitments and what is required to stay below 1.5°C. Many negotiators argue that agreeing on concrete measures to close that gap is essential, but large emitters continue to resist.Synthesis of Climate Transparency Reports. Under the Paris Agreement’s Enhanced Transparency Framework, countries must periodically report emissions, actions taken, and financial support provided or received. At COP30, the debate centers on how to make these synthesis reports more robust, comprehensive, and useful. The consultations have been tense and slow. On Sunday, the Presidency published a "summary note" outlining possible pathways, and today a draft decision was released, though reactions are still forthcoming. In the coming days, closed-door sessions will continue and could lead to various outcomes. Based on the draft, it seems increasingly likely that COP30 will end with a “cover decision” consolidating all progress and addressing these complex matters. The final scope will depend heavily on what happens during the next four days. A just energy transition: Promises and a mechanism that worksThe Belém Action Mechanism for a Just Transition is a new institutional arrangement under the UNFCCC, championed by NGOs and Global South countries. Its objective is to bring order to the currently fragmented landscape of just transition efforts. The mechanism would coordinate initiatives, systematize knowledge, and provide quality financing and support — essentially evolving the Just Transition Work Program discussed since COP27.Civil society, particularly the Climate Action Network (CAN), has invested enormous effort in developing a strong decision that advances the creation of this mechanism. The G77 + China — the largest negotiating bloc of developing countries — supported this proposal, earning CAN’s "Ray of Light" award, given to actors making significant contributions to climate justice.Some developed countries presented less ambitious proposals, but even that confirms that convergence is drawing closer. Civil society remains optimistic that a concrete, positive outcome will be achieved — and ready to celebrate it. A path to phase out fossil fuelsThis story began in 2023 at COP28 in Dubai, when, for the first time, the idea of phasing out fossil fuels appeared in an official COP text.Now, at the opening of COP30, Brazilian President Luiz Inácio Lula da Silva explicitly referenced a "route" for the energy transition, while Environment Minister Marina Silva has worked to reinforce the political momentum. Meanwhile, Colombia issued a declaration referencing the advisory opinions and seeking international support for the initiative. Several industrialized countries have revived their position through the Beyond Oil and Gas Alliance.Today, 63 countries support a commitment to "Transition Away from Fossil Fuels." However, this is not yet part of the formal negotiation agenda — initiatives remain fragmented, and efforts proceed in parallel. What could emerge is a concrete action plan, a dedicated section in the final decision, or perhaps a roadmap for a future roadmap. The alternative is that it remains a voluntary coalition of willing countries pushing the idea forward. Climate finance: The central — and most complicated — issueFinance remains the central issue at this COP, and perhaps the most complex. Several deeply interconnected discussions are underway:Article 9.1: Developing countries insist that public financing from developed nations is a binding obligation that cannot be replaced by private investment.Adaptation: A strong consensus is forming to triple the adaptation finance goal (to about USD 120 billion annually) while improving transparency and direct access to funds.The Baku–Belém Roadmap: This initiative seeks to scale up global climate finance to USD 1.3 trillion per year by 2035 through a combination of public, multilateral, and private flows.Loss and Damage Facility: The fund is technically operational but not fully capitalized. New contributions from Spain and Germany are welcome — but insufficient to meet global needs.Tropical Forests Forever Facility: Brazil has proposed this as an “investment model” for tropical forest countries. Civil society has expressed serious concerns: the model depends heavily on volatile market investments and lacks safeguards to ensure the protection of local communities and ecosystem integrity. Adaptation progress, but under the shadow of chronic underfundingDiscussions on adaptation are unfolding on two parallel fronts:Indicators for the Global Goal on Adaptation. Ten years after the Paris Agreement, there is still no consensus on how to track adaptation progress. A working group narrowed approximately 9,000 proposed indicators down to about 100, but technical and political challenges persist. Some African and Arab countries have asked to postpone final adoption until they have the financial resources and capacity to implement them. A prevailing sentiment is: "no indicators without funding" — adopting metrics without support would repeat past mistakes.Adaptation finance. Although adaptation financing is not formally included within the Global Goal on Adaptation, the two issues are inseparable. Without adequate financial support, indicators alone will be ineffective. Following the agreement on a new climate finance goal at COP29, the current debate focuses on aligning that goal with adaptation needs — especially through technology transfer, capacity building, and direct-access funding channels. Substantial gaps remain, and negotiations continue to hinge on how to categorize financial flows (private vs. public, domestic vs. international).

Science in the Service of Environmental Justice

By David Cañas and Mayela Sánchez* Science—or rather, the sciences—are the systems of knowledge that different social groups have developed over time to describe the phenomena of nature and society. Thanks to these knowledge systems, humanity has been able to find solutions to countless challenges, and today, more than ever, they must respond to global crises such as climate change, pollution, and biodiversity loss.Understanding ecosystem processes is essential for protecting the environment and providing verifiable, replicable evidence of natural phenomena and the impacts of human activities. It also enables the development of innovative solutions to protect and restore the environment.For science to contribute meaningfully to environmental justice—a concept centered on ensuring that all people enjoy a healthy environment—scientific work must be grounded in the realities of the people and communities affected by environmental degradation, who live in or rely on ecosystems vulnerable to harm. It must also be built on empathy and respect for other forms of knowledge, while seeking to reduce social inequalities.At AIDA, science is a central part of our work, supporting and complementing the strategic litigation we pursue to protect a healthy environment in Latin America. Through science, we can demonstrate the environmental impacts caused by human activities and hold those responsible accountable. How Do We Do Science at AIDA? The AIDA scientific team is a multidisciplinary group of professionals specializing in diverse fields, including geography, geology, biology, marine biology, oceanography, anthropology, and economics.Among other tasks, they collect and develop scientific evidence to strengthen the legal arguments in the cases we support across our various lines of work—from protecting the ocean and other critical ecosystems to defending human rights, such as the right to health and access to safe drinking water.The strategic use of science has been central to AIDA’s work since the organization was founded more than 25 years ago. One early example is the case of La Oroya in Peru, where a group of residents sued the government for failing to protect them from decades of heavy metal pollution caused by a metallurgical complex.Then we did something that had not been done before: we connected existing studies with the lived reality of La Oroya. This approach allowed us to demonstrate the relevance of the case and establish a clear link between pollution and its impact on the health of the city’s residents. Our analysis, compiled in the report La Oroya Cannot Wait, served to build the legal case and formulate proposals to the Peruvian government for corrective and preventive measures to address the problem. In 2024, in a decision that set a historic precedent for state oversight of industrial pollution, the Inter-American Court of Human Rights held the Peruvian state responsible and ordered it to adopt comprehensive reparations measures. Among the scientific team’s more recent contributions is a geospatial analysis of the Salar del Hombre Muerto in the Argentine provinces of Catamarca and Salta. Using maps and satellite imagery, the team documented water loss in this ecosystem caused by lithium mining.Another example is the expert report on solid waste pollution in the tributaries of the Motagua River in Guatemala, in which we recorded and characterized illegal dumps along the banks of the Chinautla River. This work enabled the affected communities to gather the evidence needed for the lawsuit they filed against the municipality of Chinautla for failing to address the contamination of rivers and soil caused by inadequate solid waste management. The Right to Science When science serves social and environmental justice, its benefits extend to everyone. This purpose was recently upheld by the Inter-American Court of Human Rights in its Advisory Opinion 32, which recognizes the “right to science” as the right of all people to enjoy the benefits of scientific and technological progress, as well as to have opportunities to contribute to scientific activity without discrimination.The Court also recognized indigenous, traditional, and local knowledge as equally valid forms of knowledge. This acknowledges how the deep understanding that indigenous peoples and local communities have of their environment—their worldview based on respect and interdependence, and their spiritual connection to nature—has been fundamental to ecosystem conservation.As an organization that uses science as a tool for environmental protection, we believe in a science that embodies these principles: one built on dialogue between different forms of knowledge, whose benefits reach all people, and which contributes to the socio-ecological transformation the planet urgently needs. *David Cañas is AIDA's Interim Director of Science; Mayela Sánchez is our digital community specialist.

A Practical Toolkit for Using Advisory Opinion 32/25 in Climate Justice Work

READ AND DOWNLOAD THE TOOLKIT The climate crisis is already affecting people and communities across Latin America and the Caribbean—damaging homes, livelihoods, ecosystems, and the fundamental right to a healthy environment.Advisory Opinion 32/25 of the Inter-American Court of Human Rights is the first of its kind to establish that both States and non-State actors—including companies—have clear and binding legal obligations to confront the causes and consequences of the climate emergency as a human rights issue.The historic interpretation, made public on July 3, 2025, gives human rights and environmental defenders a powerful new tool to demand action and justice.But how can this decision be used in real cases, campaigns, and policies today? A Legal Toolkit for Climate JusticeTo help answer that question, more than 20 experts and organizations—including AIDA—created a new publication analyzing the Court's decision with an emphasis on its practical applications.Climate Justice and Human Rights: Legal Standards and Tools from the Inter-American Court’s Advisory Opinion 32/25 contains 14 briefs, organized into four key areas:Foundational Rights and Knowledge;State and Corporate Obligations;Rights of Affected Peoples and Groups;Environmental Democracy and Remedies.

High Seas Treaty: A Major Step Forward for a Healthy, Resilient Ocean

The world is celebrating a key milestone for keeping our oceans healthy and resilient for present and future generations.This month, the final requirement was met for the entry into force of the High Seas Treaty—a long-sought agreement that is essential for the protection and sustainable use of two-thirds of the ocean, nearly half of our blue planet.The high seas are areas beyond national jurisdiction and one of the largest reservoirs of biodiversity on Earth, home to an incredible variety of marine life. They also provide food and oxygen, regulate the climate, buffer the impacts of the climate crisis, and support the livelihoods of communities that rely on fishing and tourism.After more than 20 years of discussions and over five years of formal negotiations, governments agreed on the text of the treaty at the United Nations headquarters on March 4, 2023. The treaty was formally adopted on June 19 of that year.But that was not the end of the story.For the treaty to enter into force and be implemented, it needed to be ratified by at least 60 countries—a milestone that was finally reached on September 19. The treaty will officially take effect 120 days later, on January 17, 2026.At AIDA, we have contributed to this process for many years, helping ensure that the needs of Latin America are part of both the treaty’s design and its implementation.The High Seas Treaty—short for the Agreement on the Conservation and Sustainable Use of Marine Biological Diversity of Areas Beyond National Jurisdiction (BBNJ Agreement)—offers numerous benefits. Among them, it calls for the creation and proper management of marine protected areas on the high seas to conserve and restore the ocean’s rich biodiversity.The treaty also requires that any new activity on the high seas undergo environmental impact assessments, including consideration of the cumulative effects of multiple activities on a single ecosystem.AIDA’s Role in Protecting Life on the High SeasFrom the negotiation of the High Seas Treaty to the present day, AIDA has played an active role in the process, co-leading Latin American civil society contributions to help secure a strong and effective agreement.We have done this as part of the High Seas Alliance, a coalition of more than 70 organizations working to preserve biodiversity in the high seas, where AIDA serves as regional coordinator for Latin America. In this role, we have ensured that the realities, expectations, and challenges of the continent are incorporated into the Alliance’s strategies.During the treaty negotiations, we supported Latin American delegations through internal and regional processes, providing briefings on the benefits and obligations of the agreement. In doing so, we helped strengthen the region’s capacity to engage effectively, drawing on our scientific and technical expertise.Looking ahead to implementation, we have also provided technical support to regional delegations participating in the Preparatory Committee sessions, a United Nations body tasked with advancing the issues that will be addressed at the treaty’s first Conference of the Parties (COP).Countries that ratify the treaty will be able to participate in the COP, where key decisions will be made regarding implementation and the activation of the treaty’s benefits. The first COP session will take place one year after the treaty enters into force.Beyond this much-anticipated ratification, it is essential that all countries—not just the initial 60—join the agreement to ensure fair, equitable, and sustainable governance of high seas biodiversity. This will guarantee effective implementation, fulfillment of conservation objectives, and participation in the treaty’s benefits.At AIDA, we will continue working with a Latin American focus to ensure that the High Seas Treaty translates into concrete actions for the protection and sustainable use of the high seas—a shared responsibility of all governments.

The Ocean-Climate Link: 5 Things to Know

Por Víctor Quintanilla y Natalia Oviedo*Although the ocean is essential for stabilizing the planet's climate, it is rarely the focus of attention when we talk about the global climate crisis.The ocean is our best ally in the face of the climate emergency because it absorbs much of the greenhouse gases that humanity emits and that are the source of the problem.At the same time, the ocean is a victim of the climate crisis, whose impacts are pushing it to the limit with acidification of its waters, rising sea levels, and loss of oxygen, processes that seriously affect marine life.Despite its importance, the relationship between the ocean and climate has not been fully included in international negotiations in which governments seek agreements and policies to address the climate crisis.Faced with this gap and in a historic breakthrough, the International Tribunal for the Law of the Sea issued a ruling in 2024 clarifying the obligations of States to protect the marine environment from the climate crisis.Below, we present five keys to understanding the link between the ocean and climate.1. The role of the ocean in the climate crisis.According to the Intergovernmental Panel on Climate Change, the ocean is “a fundamental climate regulator on timescales ranging from seasonal to millennial.” Since 1955, it has absorbed 90 percent of the excess heat caused by global warming, along with a quarter of the carbon dioxide released by human activities.Ocean currents transport warm water from the tropics to the poles, sending colder water back. This balances the temperature and makes much of the Earth habitable. The ocean influences climate variations on land by being the main source of rain, which feeds rivers and other vital freshwater systems.The ocean is known as a lung for the planet because, through microscopic organisms known as phytoplankton, it is responsible for generating approximately half of the world's oxygen supply. In turn, coastal ecosystems such as mangroves, marshes, and seagrass beds absorb enormous amounts of carbon from the atmosphere, mitigating the climate crisis. 2. The impact of the climate crisis on the ocean.The climate crisis alters the physical and chemical properties of the ocean, affecting its ability to regulate the climate. One of the irreversible impacts of climate change is ocean warming, whose rate and heat absorption has more than doubled since 1993. As its waters warm, they begin to release carbon dioxide back into the atmosphere.In addition, rising ocean temperatures are expected to reduce the amount of oxygen available, altering nutrient cycles and thereby affecting fish distribution and abundance. Another consequence is sea level rise, which is due to thermal expansion of the ocean and loss of land ice.Finally, the absorption of increasing amounts of carbon dioxide has resulted in ocean acidification, understood as a decrease in pH. This reduces calcium levels, a substance necessary for the shells and external skeletons of various species of marine fauna and ecosystems such as coral reefs.3. The inclusion of the ocean in international climate negotiations.Although the link between the ocean and climate change has been recognized since the beginning of negotiations under the United Nations Framework Convention on Climate Change (UNFCCC)—by including the ocean in the definition of “climate system”—its presence in these negotiations has been gradual. A decisive milestone occurred at the 25th UN Climate Change Conference (COP25) in 2019, where the first official dialogue on the subject was called for, resulting in recommendations to align climate and ocean action, while also promoting the mobilization of financing to protect marine ecosystems. Since then, the ocean has earned a permanent place on the climate agenda. At subsequent conferences, the inclusion of the ocean was further expanded. The Glasgow Climate Pact (COP26, 2021) recognized the ocean as an ally in carbon absorption, called for the integration of ocean-based action into UNFCCC work plans, and mandated an annual dialogue on the topic. At COP27 (2022), countries were encouraged to include ocean-based action in their nationally determined contributions (NDCs). And at COP28 (2023), the ocean was included in the first global stocktake of the Paris Agreement.Ahead of this year's COP30 in Brazil, which will have a specific agenda on “Forests, Oceans, and Biodiversity,” the challenge is to move from political recognition to the implementation of concrete actions to protect the ocean.4. States' obligations to protect the ocean in the face of the climate crisis.The health and resilience of the ocean is essential not only for addressing the climate crisis, but also for the exercise of fundamental human rights such as life, health, culture, food, access to water, and the right to a healthy environment. This highlights the interdependence between the ocean, climate change, and human rights.Recognizing this link, on May 21, 2024, the International Tribunal for the Law of the Sea issued an important decision clarifying the obligations of States to preserve the ocean in the face of the climate crisis. These duties include adopting concrete mitigation measures to minimize the release of toxic substances into the marine environment, as well as exercising strict due diligence to ensure that non-state actors effectively comply with such measures.The tribunal emphasized the obligations of states to prevent climate change-related pollution that affects other states and the marine environment outside national jurisdiction. In relation to the right to a healthy environment, the ruling emphasizes the use of precautionary and ecosystem approaches in the context of states' obligations to conduct environmental and socioeconomic impact assessments of any activity that may cause marine pollution related to climate change. This includes that, in the face of the possibility of serious or irreversible damage to the marine environment, the lack of full scientific certainty should not be used as an excuse to delay protective measures.5. Some key actions to protect our ocean and, with it, the climate.Effective protection of our ocean requires the commitment of governments, which must act at the national and international levels to prioritize its health. These include:Prioritizing concrete measures that integrate the ocean into climate mitigation and adaptation actions. Among the most effective are the protection and restoration of ecosystems, especially those that, in addition to capturing and storing enormous amounts of carbon, protect coastlines and maintain vital ecosystem services (mangroves, marshes, seagrass beds, coastal wetlands, and coral reefs, among others).Ensuring the protection and sustainable use of biodiversity in the ocean area beyond national jurisdiction. This involves the effective implementation of the High Seas Treaty, which will enter into force on January 17, 2026, as well as its ratification by countries that have not yet done so, to ensure fair, equitable, and sustainable governance.Defending the deep sea from mining. This requires imposing moratoriums on deep-sea mining activities on the grounds that there is insufficient technical and scientific information to prevent, control, and mitigate the potential impacts on the biological diversity of unknown ecosystems in deep waters and on the seabed.Protect the rights of coastal and island communities, which depend on fishing and local tourism for their livelihoods. These populations face increasing impacts from the climate crisis and multiple environmental pressures. Governments have a responsibility to ensure their resilience and well-being by safeguarding the marine and coastal biodiversity that sustains their ways of life and culture.Acknowledging the link between the ocean and climate, and translating it into concrete and effective measures, is essential to protect and maintain the balance of both life systems.This is what will guarantee the health of marine and coastal biodiversity, our food security, and, ultimately, a future for the planet.* Víctor Quintanilla is AIDA's Content Coordinator; Natalia Oviedo is a Costa Rican international lawyer and former intern at the organization.
