Background on Petrobras and its Significance

Petrobras, Brazil’s state-owned oil giant, is the largest oil producer in Latin America, with daily production expected to reach 3.4 million barrels by 2024. Despite this, half of Brazil’s energy comes from renewable sources, reflecting the country’s commitment to sustainability and combating climate change.

Oil Exploration Near Amazon River Mouth

Petrobras announced on Monday that it has received authorization to start drilling for oil approximately 500 kilometers from the Amazon River’s mouth, just days before Brazil hosts the global climate summit, COP30.

“Petrobras complies with all requirements set by the environmental regulatory agency Ibama,” the company stated in a press release sent to AFP.

Environmental Concerns and Government Stance

The Ibama environmental agency approved the drilling in the shallow waters of the Eastern Margin, near the Amazon River’s mouth. This project puts President Luiz Inácio Lula da Silva’s government at odds with environmentalists.

The drilling is set to commence “immediately” and last an estimated five months, according to Petrobras. The Eastern Margin area, 160 kilometers off the coast, is part of a vast maritime region where Guyana and Suriname have already discovered massive oil reserves.

The potential of these new oil fields is significant, estimated at 10 billion barrels. Exploring this new frontier for Brazilian oil may seem paradoxical, given the country’s efforts to lead in the fight against climate change.

Brazil’s Climate Summit and Oil Extraction

Brazil will host the UN’s COP30 climate summit in the Amazonian city of Belém from November 10 to 21. In response to criticism from environmental organizations, Lula argues that oil extraction is necessary to fund the transition to clean energy sources.

In 2023, Ibama denied Petrobras an exploration license, citing insufficient guarantees to protect wildlife in case of an oil spill. Petrobras appealed this decision, and pressure increased from Lula, who claimed that Ibama was acting as if it were “against the government.”

A technical note from Ibama, consulted by AFP in February, recommended “denying the environmental license,” emphasizing the risk of “massive loss of biodiversity in a highly sensitive marine ecosystem.”

Approval Following Pre-Operational Tests

The license was granted after Petrobras conducted pre-operational tests in August to demonstrate its capability to respond to a potential oil spill.
