Chile – Climate and Human Rights Litigation Database

Summary:
On 2 July 2024, a complaint was filed by the public prosecutor of Antofagasta, representing the State of Chile, against Quiborax S.A., a limited liability company in the mining, agrochemical and energy sectors that produces and exports boric acid. The case concerns ulexite mining in the surface salt deposits in the Salar de Surire, located in the commune of Putre, Region of Arica and Parinacota (the ‘Salar’), and related environmental damage. This includes permanent damage to the Salar itself, alterations of runoff and flooding patterns, a loss of supporting, regulating and cultural ecosystem services, serious habitat alterations and losses, and biodiversity and environmental impacts. This resulted in continuous, cumulative, permanent and irreparable environmental damage to an iconic national and international protected area. The State sought compensation, mitigation and risk reduction measures. In doing so, it relied on Section 19 Nº 8 of the Chilean Constitution, which recognizes the right to live in an environment free of pollution, mandating the State to ensure that this right ‘is not affected and to protect the preservation of nature’, while its subsection 2° confers power to the legislator to ‘establish specific restrictions to the exercise of certain rights or freedoms to protect the environment’.

In doing so, the State cited principles of conservation and sustainable development, and Chile’s international obligations including the Convention for the Protection of the Flora, Fauna and Natural Scenic Beauty of the countries of the Americas (Washington Convention); the Convention on Biological Diversity; the Convention on Biological Diversity; the Convention on Wetlands of International Importance (RAMSAR Convention); the Convention on the Conservation of Migratory Species of Wild Fauna; the Convention on the Protection of World Cultural and Natural Heritage; the Convention on the Conservation of Migratory Species of Wild Fauna; and the Convention on the Protection of World Cultural and Natural Heritage, the UNFCCC, and the Paris Agreement as well as Chile’s Nationally Determined Contribution under that framework.

The State also invoked:

the multiplier effect of climate change and the need to consider this liability for environmental damage, as it constitutes an unavoidable context that must be taken into account, given its capacity to enhance and reinforce the short, medium and long term effects of impairments, deterioration or losses inflicted on environmental components. In this sense, climate change multiplies the effect of impairments, deterioration or losses affecting the regulation or support services provided by abiotic components, such as soil or water or ecosystems themselves, especially threatening unique or singular ecosystems, valuable for their expression of biodiversity. This is precisely what the sixth report of the United Nations Intergovernmental Panel on Climate Change (from now on ‘the IPCC’) on the physical basis of climate change, published in August 2021, has revealed in relation to the environment and sustainable development. It is therefore urgent, on the one hand, to determine the exact influence of climate change on this degraded ecosystem as the amount of rainwater from the summer rains increases, and, on the other hand, to strive to conserve a climatic refuge such as Surire, which sustains the biodiversity not only of the region and the country, but also of the entire world.

Summary:

On 25 November 2021, a group of women from the city of Huasco, alongside Doris Zamorano, a member of a civil society organization in Huasco, brought a constitutional action against Chile’s omission in coordinating the early closure of two coal-fired power plants. The Chilean government had signed closure agreements with owners of various thermoelectric power plants, but the two plants in question were absent from these agreements. They would be subject to the general clause requiring closure of all coal-fired power plants by the year 2040. The petitioners argued the emissions from the powerplants and the uncertainty as to their closure in advance of the year 2040 contributes to interferences with their exercise and enjoyment of fundamental rights. In particular, they point to the governmental authorities’ awareness about the persistent local air pollution and treatment of Huasco as a ‘sacrifice zone,’ as well as Chile’s climate mitigation commitments.

On 2 May 2022, the Court of Appeals of Copiapo dismissed the petition on the ground that adjudication of the issues raised by the petitioners was beyond its competence. The petitioners have filed an appeal against this decision before the Supreme Court of Chile.

Claims:

The applicants argue that the State’s omissions consist in its failure to close two coal-fired power plants, failure to justify the exclusion of the two power plants from the list of plants due to be closed earlier than 2040 pursuant to its climate policy, and toleration of emissions from the two power plants despite no compensation being granted for the negative environmental impacts from their operation. The petition alleges that these omissions violate their constitutional rights to equality, to life, physical and psychological liberty, to an environment free from contamination, and to the protection of their health, as well as a breach of the State’s administrative duty not to act arbitrarily. In support of the latter contention, the petitioners relied on the administrative law principles of service of the human person, coordination between State organs and the environmental principles of prevention and precaution. Further, they argued that the normative content of the State’s duty were to be informed by Sustainable Development Goals, International Labour Organisation Guidelines on Just Transition, UN Framework Convention on Climate Change, Paris Agreement and Chile’s 2020 NDC Communication under the Paris Agreement. By way of evidence, the petitioners relied on reports of high levels of air pollution in the city of Huasco, and a comparative analysis of morbidity rates and incidences of respiratory illnesses in Huasco and Caldera, a similar city that was not in the vicinity of coal-fired power plants.

The petitioners requested the Court of Appeals of Copiapo to order the concerned state organs to (i) establish and implement a plan to effect the early closure of the two power plants, and (ii) establish a compensation plan for historical and current emissions of the power plants to redress the environmental and health-related impacts.

In his reply, the Minister of Energy challenged the appropriateness of a judicial review of complex public policies which were the result of a democratic and representative participative process. The Minister also elaborated on the procedural history and content of the government’s policy on decarbonisation, and the limits of the legal competences of the various Ministries vis-à-vis regulation of private actors in the energy sector, to rebut the petitioners’ arguments about the State’s breach of administrative duties. The reply submitted by the Minister of Environment argued that there is no omission attributable to the Ministry of the Environment since regulation of power plants falls within the authority of the Ministry of Energy, and that environmental management instruments were enacted to improve the air quality in Huasco. The Minister of Health submitted a similar reply. The Undersecretary General of the Presidency argued that State authorities lack the power to order the early closure of the said power plants, and that all of the authorities named in the petition had taken relevant measures in relation to the factual situation described by the petitioners.

Decision:

On 2 May 2022, the Court of Appeals of Copiapo rendered its decision wherein it rejected the petition. The Court noted that petitioners’ action for constitutional review of the State’s omission suggests that they disagree with its actions which form part of the public policy on decarbonisation of the country. However, this policy was developed and implemented with the participation of various state organs (with the Ministry of Energy being at the head of them) and it is not for the Court to substitute itself for them and order a replacement or modification of such policy. The Court also noted the involvement of non-State stakeholders, including both actors from the industry and civil society, in the establishment of the decarbonisation policy.

Additionally, with respect to closure of power plants, the Court noted that State organs do not have the authority to demand closures and that such an outcome can only be achieved through agreements between the State and the concerned owners of the power plants. The Court concluded that the fact that the agreement concluded between the State and the owner of the two power plants in question does not envisage a concrete plan for their closure, as it does for some other power plants, does not evince arbitrariness.
