Protecting the health of La Oroya's residents from toxic pollution
For more than 20 years, residents of La Oroya have been seeking justice and reparations after a metallurgical complex caused heavy metal pollution in their community—in violation of their fundamental rights—and the government failed to take adequate measures to protect them.
On March 22, 2024, the Inter-American Court of Human Rights issued its judgment in the case. It found Peru responsible and ordered it to adopt comprehensive reparation measures. This decision is a historic opportunity to restore the rights of the victims, as well as an important precedent for the protection of the right to a healthy environment in Latin America and for adequate state oversight of corporate activities.
Background
La Oroya is a small city in Peru’s central mountain range, in the department of Junín, about 176 km from Lima. It has a population of around 30,000 inhabitants.
There, in 1922, the U.S. company Cerro de Pasco Cooper Corporation installed the La Oroya Metallurgical Complex to process ore concentrates with high levels of lead, copper, zinc, silver and gold, as well as other contaminants such as sulfur, cadmium and arsenic.
The complex was nationalized in 1974 and operated by the State until 1997, when it was acquired by the US Doe Run Company through its subsidiary Doe Run Peru. In 2009, due to the company's financial crisis, the complex's operations were suspended.
Decades of damage to public health
The Peruvian State - due to the lack of adequate control systems, constant supervision, imposition of sanctions and adoption of immediate actions - has allowed the metallurgical complex to generate very high levels of contamination for decades that have seriously affected the health of residents of La Oroya for generations.
Those living in La Oroya have a higher risk or propensity to develop cancer due to historical exposure to heavy metals. While the health effects of toxic contamination are not immediately noticeable, they may be irreversible or become evident over the long term, affecting the population at various levels. Moreover, the impacts have been differentiated —and even more severe— among children, women and the elderly.
Most of the affected people presented lead levels higher than those recommended by the World Health Organization and, in some cases, higher levels of arsenic and cadmium; in addition to stress, anxiety, skin disorders, gastric problems, chronic headaches and respiratory or cardiac problems, among others.
The search for justice
Over time, several actions were brought at the national and international levels to obtain oversight of the metallurgical complex and its impacts, as well as to obtain redress for the violation of the rights of affected people.
AIDA became involved with La Oroya in 1997 and, since then, we’ve employed various strategies to protect public health, the environment and the rights of its inhabitants.
In 2002, our publication La Oroya Cannot Wait helped to make La Oroya's situation visible internationally and demand remedial measures.
That same year, a group of residents of La Oroya filed an enforcement action against the Ministry of Health and the General Directorate of Environmental Health to protect their rights and those of the rest of the population.
In 2006, they obtained a partially favorable decision from the Constitutional Court that ordered protective measures. However, after more than 14 years, no measures were taken to implement the ruling and the highest court did not take action to enforce it.
Given the lack of effective responses at the national level, AIDA —together with an international coalition of organizations— took the case to the Inter-American Commission on Human Rights (IACHR) and in November 2005 requested measures to protect the right to life, personal integrity and health of the people affected. In 2006, we filed a complaint with the IACHR against the Peruvian State for the violation of the human rights of La Oroya residents.
In 2007, in response to the petition, the IACHR granted protection measures to 65 people from La Oroya and in 2016 extended them to another 15.
Current Situation
To date, the protection measures granted by the IACHR are still in effect. Although the State has issued some decisions to somewhat control the company and the levels of contamination in the area, these have not been effective in protecting the rights of the population or in urgently implementing the necessary actions in La Oroya.
Although the levels of lead and other heavy metals in the blood have decreased since the suspension of operations at the complex, this does not imply that the effects of the contamination have disappeared because the metals remain in other parts of the body and their impacts can appear over the years. The State has not carried out a comprehensive diagnosis and follow-up of the people who were highly exposed to heavy metals at La Oroya. There is also a lack of an epidemiological and blood study on children to show the current state of contamination of the population and its comparison with the studies carried out between 1999 and 2005.
The case before the Inter-American Court
As for the international complaint, in October 2021 —15 years after the process began— the IACHR adopted a decision on the merits of the case and submitted it to the Inter-American Court of Human Rights, after establishing the international responsibility of the Peruvian State in the violation of human rights of residents of La Oroya.
The Court heard the case at a public hearing in October 2022. More than a year later, on March 22, 2024, the international court issued its judgment. In its ruling, the first of its kind, it held Peru responsible for violating the rights of the residents of La Oroya and ordered the government to adopt comprehensive reparation measures, including environmental remediation, reduction and mitigation of polluting emissions, air quality monitoring, free and specialized medical care, compensation, and a resettlement plan for the affected people.

10 good news stories from 2022, for a sustainable future
This year we saw important advances toward environmental justice in Latin America, and around the world. We’re celebrating decisions at the local, national and international levels that help move us toward a more sustainable future for all. We chose for you our top 10—stories that represent important advances for the protection of biodiversity, for the respect of human rights, for the recognition of indigenous and traditional populations, for responsible finance, for climate litigation as a tool for accountability, and for the hope of a just energy transition. 1. Ecuador expanded the Galapagos Marine Reserve This year, through a national decree, Ecuador added 60 thousand square kilometers to the Galapagos Islands, the first site to be declared a UNESCO World Heritage Site. The new area, called the Hermandad Reserve, creates a marine corridor between the Galapagos Islands and Cocos Island in Costa Rica that will serve as a safe passageway for the dozens of protected species that move through the area, including sharks, whales, turtles, and dolphins. After the expansion, nearly 200 thousand square kilometers of the Galapagos have varying degrees of protection. Ecuador and Costa Rica have since called on Panama and Colombia to add protected areas to the new Reserve. 2. Honduras declared territory free from open-pit mining In February, the new government of Honduras declared the entire territory of the Central American country free of open-pit mining. According to a communiqué from the Secretariat of Natural Resources, Environment and Mines, the decision was made following the principles of climate justice and with a view toward respecting and protecting natural resources. Along these same lines, the government issued three other provisions: to cancel the approval of permits for extractive exploitation; to approve a mining moratorium through which environmental licenses, permits and concessions for metallic and non-metallic exploration and exploitation will be reviewed; and to intervene immediately in natural areas of high ecological value for their conservation. 3. Mexican Supreme Court protected the Veracruz Reef Residents of the coastal state of Veracruz and the Mexican Center for Environmental Law (CEMDA) won their case before the country’s supreme court to protect the Veracruz Reef, the largest reef system in the Gulf of Mexico. The Court unanimously recognized that the authorities violated the community's right to a healthy environment by approving the expansion of the Port of Veracruz. AIDA and Earthjustice presented evidence for recognition of the human rights to a healthy environment and access to justice enshrined in international law. These rights obligate the Mexican government to allow anyone whose rights are threatened by environmental degradation to achieve justice regardless of whether their connection to the threatened ecosystem is indirect or remote. This victory was a collective effort between organizations and the community, and sets a precedent for environmental justice in the region as the ruling points to Mexico's international obligations, including those under the Escazú Agreement. 4. Chile took important steps towards energy transition In June, Chile published the Framework Law on Climate Change, the first in its history, which assigns responsibilities for mitigating emissions and adapting to climate change. The law is the first in the region to establish a carbon neutral goal for 2050, which must be reviewed every five years. In addition, faced with a wave of intoxications derived from pollution, the President announced the closure of the Ventanas Smelter in Valparaíso. Congress is currently considering a bill to approve the closure of Ventanas, which will be progressive. Both the company and the government have committed to not leaving workers without a job, to taking charge of environmental remediation, and to continuing to process small-scale mining minerals. The corporation Enel also closed its last coal-fired power plant in Coronel, a region with a history of environmental conflicts due to impacts on the health and livelihoods of the community. The cases of Enel and Ventanas remind us that decisions towards energy transition must be made respecting the rights of the people involved, both the community and longtime workers. 5. United Nations recognized a healthy environment as a universal right In July, in a historic resolution, the United Nations General Assembly recognized a safe, healthy, clean and sustainable environment as a universal human right. Since this right was left out of the Universal Declaration of Human Rights in 1948, the decision marks a milestone for international law, particularly in the area of human rights. "This resolution conveys the message that no one can take away our nature, clean air and water, or deprive us of a stable climate," said Inger Andersen, head of the United Nations Environment Programme. "At least not without a fight." This news was cause for great celebration at AIDA because the human right to a healthy environment has been the focus of our work since our founding. Costa Rica was one of the countries that led the proposal and that behind this milestone there are decades of work by organizations, movements and communities. 6. For first time, the Inter-American Bank prepared a responsible exit plan In Guatemala, Mayan communities filed a complaint about the damage that two hydroelectric projects caused to their territory, livelihoods and social fabric. The projects had received financing from the Inter-American Development Bank (IDB) Group. After the Bank's accountability office concluded that IDB Invest failed to comply with its operational policies and safeguards, the bank decided to withdraw its financing from the projects. In addition to the divestment, and as a result of the complaint, the IDB Group developed a responsible exit plan for the first time in its history. This sets a historic precedent for all communities affected by investments by international financial institutions. Although there are challenges for the implementation of the exit plan, the case is a great opportunity for the IDB to strengthen its policies as well as the monitoring and supervision of the projects it supports in order to avoid non-compliance with its guidelines. 7. Recognition grew for the region’s indigenous peoples Despite the fact that indigenous and traditional peoples suffer constant violations of their human rights—often for protecting their own territory—this year their contributions, knowledge and work were recognized on various fronts. In Colombia, the ancestral knowledge system of the Arhuaco, Kankuamo, Kogui and Wiwa indigenous peoples of the Sierra Nevada de Santa Marta was recognized as Intangible Cultural Heritage of Humanity by UNESCO. In Brazil, Sonia Guajajara and Célia Xakriabá, indigenous women with environmental and social causes, were elected to Congress in the October general elections. And, for the first time in Ecuador, Amazonian indigenous organizations received $2.5 million to finance conservation and deforestation reduction projects. 8. World leaders created a fund for climate loss and damage One of the strongest demands of the global South at climate summits had been the creation of a fund for losses and damages for the countries most vulnerable to the climate crisis. This year, at the 27th United Nations Climate Change Conference (COP27), a financing mechanism was finally created for this purpose. This mechanism will seek to mobilize resources to complement existing ones, and calls for richer countries to contribute more. The decision adopted at COP27 also called on the World Bank and the International Monetary Fund to provide "financing solutions." The details for the fund’s operation and for the inclusion of a human rights approach are a task for the next conference. 9. Brazilian court settled first-ever climate litigation In 2020, four political parties and two civil society organizations filed a lawsuit over the Brazilian government's failure to provide resources to the federal Climate Fund. The case was resolved in July of this year, becoming the first climate litigation in Brazil's Supreme Federal Tribunal, the highest court in the country. The court determined that the government has a constitutional duty to allocate the necessary economic resources for the operation of the Climate Fund, which had been paralyzed in recent years. In its findings, the court equated the Paris Agreement with a human rights treaty, which may give way for courts and judges in other Latin American countries to make the same recognition. This case shows that strategic climate litigation is an effective and necessary way to demand that governments and companies in the continent comply with their climate commitments. 10. Historic agreement reached to protect global biodiversity In December, roughly 200 member countries of the Convention on Biological Diversity adopted a historic agreement that seeks to reverse decades of environmental degradation and the resulting risks to the planet's species and ecosystems. Gathered at the 15th United Nations Conference on Biodiversity in Montreal, Canada, the countries' delegates reached an agreement committing to protect at least 30 percent of the world's terrestrial and marine areas by 2030. In addition, they agreed to provide at least $20 billion in annual international aid for biodiversity by 2025 and at least $30 billion by 2030. Want more good news?
