Watch the video and see how the data was built in practice.

The reduction rates and savings projections shown in the video were not chosen at random. Each figure was drawn from rigorous scientific studies, published in high-impact journals, conducted by internationally recognized institutions such as the World Health Organization (WHO), Harvard University, the Federal University of Minas Gerais (UFMG), and the Cochrane Library.

The projections specific to Petrobras were calculated by applying these scientifically validated percentages to the company's actual reality, based on public data (approximately 45,000 employees) and a transparent scientific methodology.

We believe methodological transparency is essential to a solid partnership. That's why we detail every source used and the projection logic applied. We are available to go deeper into any of the cited studies or provide supporting documentation.
