RIO DE JANEIRO — Brazil's environmental regulator refused on Wednesday to grant a license for a controversial offshore oil drilling project near the mouth of the Amazon River, prompting celebration from environmentalists who had warned of its potential impact.
The decision to reject the state-run oil company Petrobras' request to drill the FZA-M-59 block was made "as a function of a group of technical inconsistencies," said the agency's president, Rodrigo Agostinho, who highlighted environmental concerns.
With Brazil's existing production set to peak in coming years, Petrobras has sought to secure more reserves off Brazil's northern coast. The company earmarked almost half its five-year, $6 billion exploration budget for the area.
CEO Jean Paul Prates had said that the first well would be temporary and that the company has never recorded a leak in offshore drilling. The company failed to convince the environmental agency.
"There is no doubt that Petrobras was offered every opportunity to remedy critical points of its project, but that it still presents worrisome inconsistencies for the safe operation in a new exploratory frontier with high socioenvironmental vulnerability," Agostinho wrote in his decision.
The unique and biodiverse area is home to little-studied swaths of mangroves and a coral reef, and activists and experts had said the project risked leaks that could imperil the sensitive environment.
Eighty civil society and environmental organizations, including WWF Brasil and Greenpeace, had called for the license to be rejected pending an in-depth study.
"Agostinho is protecting a virtually unknown ecosystem and maintains the coherence of the Lula government, which has promised in its discourse to be guided by the fight against the climate crisis," the Climate Observatory, a network of environmental non-profits, said in a statement.
