But is it actually possible to explore and produce oil with respect for the environment? We have proved it is. In addition to supporting environmental projects - from 2003 to 2008, the Petrobras Environmental Program invested upwards of R$210 million - we are the first to give examples of sustainable actions.

Our focus is on eco-efficiency. To us, it does not suffice to produce, refine and distribute oil within the strictest safety standards. With rational water and energy use, in association with the generation of the least possible amounts of effluents, residues and emissions at all of our units, we reduce our impact on the environment and reinforce our commitment to pursuing excellence in our operations.its in the hands of Petrobras
