NGOs Go to Federal Court in Pará to Halt Petrobras Drilling in the Foz do Amazonas Basin, Alleging Environmental Risks and Questioning the License Granted by IBAMA
On Wednesday (22), a group of NGOs filed a public civil action in the Federal Court of Pará to suspend the oil drilling by Petrobras in the Foz do Amazonas basin. According to CNN Brasil, the initiative challenges the IBAMA license granted days earlier and raises serious concerns about the environmental and social impacts of the activity, especially on indigenous, quilombola, and extractive communities in the region.
IBAMA License Under Question: Technical Failures and Lack of Consultation
The action represents a landmark in the fight for the protection of the Amazon and traditional peoples. With 161 pages, the document is signed by organizations such as Climate Observatory, Greenpeace, WWF, and Arayara, as well as local entities. The request includes an injunction for the immediate suspension of activities and the annulment of the environmental license issued by IBAMA.
The primary criticism from the NGOs regarding the IBAMA license is the lack of prior, free, and informed consultation with traditional communities, as mandated by the ILO Convention 169, to which Brazil is a signatory. Without hearing the affected peoples, the licensing process loses legitimacy and legality.

Additionally, the organizations point out technical flaws in the environmental risk modeling. According to the action, the impact study did not adequately consider the surface ocean currents and water columns in the region, which could compromise the effectiveness of contingency plans in the event of an oil spill.
NGOs Highlight Ecological Importance of the Foz do Amazonas Basin
The Foz do Amazonas basin is considered one of the most biodiverse regions on the planet. Located on the Brazilian equatorial margin, it is home to unique coral reefs and is a habitat for threatened species such as the manatee and the boto.
Studies by Greenpeace and Brazilian universities indicate that the area is a true marine nursery, of global significance for the conservation of ocean life.
Any environmental impact in this region could be irreversible. The drilling of oil wells poses a high risk of contamination, especially in such a sensitive and still under-studied ecosystem.
Federal Court of Pará Evaluates Suspension Request Made by NGOs
The action was filed in the 9th Federal Environmental and Agrarian Court of the Federal Court of Pará, which will now be responsible for evaluating the request for an injunction. The responsible judge may order the immediate suspension of Petrobras’s activities in the region until the merits of the case are judged.
The court’s decision could define the future of oil exploration in the Amazon. If the injunction is granted, Petrobras will have to cease its operations in block FZA-M-59, located about 175 km off the coast of Amapá.
Petrobras Defends Legality and Safety of Operations
In an official statement, Petrobras stated that drilling in the Foz do Amazonas basin is exploratory and aims only to assess the production potential of the area. The company emphasized that it follows all required environmental protocols and that the IBAMA license was obtained after rigorous technical analysis.
The president of the state-owned company, Magda Chambriard, has stated on other occasions that Petrobras is committed to sustainability and responsible development of the equatorial margin. However, NGOs argue that the history of environmental accidents in the oil sector requires heightened caution.
International Mobilization and Political Context
The controversy occurs on the eve of COP-30, which will be held in Belém (PA), increasing international visibility of the case. Various international entities have already expressed support for Brazilian NGOs, warning of the risk of setbacks in the country’s environmental policies.
International pressure may influence the judicial decision and the stance of the federal government. Brazil has commitments under the Paris Agreement and the UN’s 2030 Agenda, which include the protection of marine ecosystems and respect for the rights of indigenous peoples.
The extractive, indigenous, and quilombola communities in the region report a lack of dialogue and fear the impacts of oil activities on their livelihoods. Artisanal fishing, the main source of income for many families, may be directly affected by potential spills or changes in the marine ecosystem.
Without consultation and guarantees, these populations remain vulnerable. The NGOs’ action seeks to ensure that their rights are respected and that economic development does not occur at the expense of environmental destruction and human rights violations.
NGOs and the Fight for Transparency and Accountability
The NGOs involved in the action have a history of working in defense of the environment and human rights. The Climate Observatory, for example, brings together more than 70 entities and works on formulating sustainable public policies. Greenpeace has a global presence and is known for its mobilization and advocacy campaigns.
The legal action in this case is an attempt to ensure transparency and accountability. The organizations argue that environmental licensing needs to be more rigorous and participatory, especially in sensitive areas like the Amazon.
Possible Paths for the Future of the Foz do Amazonas Basin
The action taken by the NGOs in the Federal Court of Pará against the Petrobras and the IBAMA license marks a decisive moment for the future of the Foz do Amazonas basin. In a context of climate emergency and increasing international pressure for environmental responsibility, Brazil needs to balance economic development with environmental preservation and social justice.
The court’s decision could establish an important precedent for environmental licensing in the country. More than a legal dispute, it is a choice about the model of development that Brazil wants to pursue.
