Petrobras Is Among The 20 Companies Responsible For More Than 1/3 Of Greenhouse Gas Emissions Since 1965.
Petrobras was listed among the twenty oil, natural gas, and coal producing companies that contribute most to global pollution according to the study, discussed by the British newspaper The Guardian on Wednesday, October 9. Earlier this month, the state-owned company began reducing the sulfur content of marine fuel to 0.5% for the sake of the environment.
The study assessed what global companies extracted from the ground and the subsequent emissions for which these fossil fuels are responsible, since 1965, the year experts say the environmental impact of fossil fuels began to be recognized by industry leaders and politicians.

The 20 oil, natural gas, and coal companies are responsible for (35%) 480.16 billion tons of emissions of the two pollutants, amid a total of 1.35 trillion tons.
The list includes 12 state-owned companies and eight private ones. Leading the list is the Saudi state-owned company Saudi Aramco, responsible for the emission of 59.26 billion tons of carbon dioxide and equivalents, 4.38% of the global total during the analyzed period.
Next are the American company Chevron, with 3.20% of the total, and the Russian company Gazprom, with 3.19%. Petrobras accounts for 8.68 billion tons of carbon equivalent, representing 0.64% of the total.
The Defense of Petrobras
Petrobras stated, through a press advisory, that it is seeking ways to apply in its operations “technologies that have a direct consequence of reducing carbon intensity, with significant results already achieved.”
According to the company’s announcement, “since 2008, 9.8 million tons of CO2 have already been reinjected from the pre-salt fields in the Santos Basin,” and by 2025, “the company projects to reinject about 40 million tons of CO2.”
“Between 2009 and 2018, the emission of more than 120 million tons of CO2 was avoided, which is equivalent to two years of total emissions from Petrobras,” says the announcement.
The so-called reinjection process involves separating the CO2 from the oil and gas extracted from the well and reinjecting it back into the oil or gas reservoir, also increasing internal pressure which leads to increased production.
