Recently, Petrobras was denied permission by Brazil's environmental regulator to conduct an oil exploration operation near the mouth of the Amazon River. The oil business planned to begin drilling in the Tapajos Basin, which is a region close to Brazil's northern coast. The region, according to activists, is "unique" and has coral reefs and flora that are chemically sensitive. The EPA was pressured by a number of environmental groups to deny Petrobras' proposal. Rodrigo Agostinho, the head of the environmental agency, stated last week that the corporation had not corrected several "technical inconsistencies" in its plan when he made his decision.

Jean Paul Prates is the CEO of Petrobras. He said that all over offshore projects, the corporation has never had an oil spill. But despite his assurances, the CIA was not convinced of the project's security. Petrobras said that it will challenge the judgement. The oil corporation believes it's crucial for the economy of the country to explore the northern the coast. According to Petrobras, Brazil's oil output will shortly reach its peak before beginning to decline. Half of the company's USD 6 billion exploration budget for the following five years was slated to be allocated to the region.

Several organizations, including the World Wildlife Fund and Greenpeace, asked the agency to deny Petrobras' proposal. Other organization was Health and Happiness, a nonprofit organization run by Caetano Scannavino in Brazil. The choice, in his opinion, was a good one and demonstrated "prioritising science in the service of the collective." He continued by saying that any error made there will harm the ecosystem. He said that the agency's approval of drilling would have violated the Brazilian government's "promise of a decarbonized future."

Luiz Inacio Lula da Silva president of Brazil. During his presidency, which lasted from 2003 to 2010, he approved offshore drilling. The huge oil projects contributed to the development of Brazilian programmes for welfare, education, and health. Some Workers' Party politicians believe that using oil money will enhance social expenditures.

Now, Lula declares his support for the environment. He defeated former President Jair Bolsonaro in the election last year due to his pledges to safeguard the Amazon rain forest. Experts and protestors claim that if his administration approved the offshore drilling project, Lula's image would suffer.

Former director of Brazil's environmental agency Suely Araujo currently works with the Climate Observatory. According to Araujo, Brazil should begin to reduce its reliance on fossil fuels like oil and gas in light of the decision to halt the drilling project.
