Leadership and Administration Board
Vale’s Executive Board is headed by Eduardo Bartolomeo, our CEO.
See the below list for his and our Executive Vice-Presidents' profiles.
Before being appointed president of the company, Bartolomeo was executive director of Base Metals, in Canada, in 2018. His first tenure at Vale took place between 2004 and 2012, when he worked on the recognized Executive Board of Logistics Operations. The executive structured the logistics to support Vale's operations during the last super cycle and, in December 2010, led the creation of VLI, a general cargo transport company whose control was sold by Vale in 2014 for R$4.7 billion.
Bartolomeo also led the project to duplicate the Carajás Railroad and the expansion of the Ponta da Madeira Maritime Terminal (TMPM), which enabled Vale to increase the production capacity of the Northern System. At the time, he developed the Vale Management Model (VPS), which, combined with investment in technology and professional qualification, resulted in significant gains for the company. The VPS is being implemented in all of Vale's business units as an important lever for safety and operational excellence.
As Vale's CEO, the executive has prioritized people, safety and repair in Brumadinho. Bartolomeo introduced two new strategic pillars for the company (Safety and Operational Excellence and New Pact with Society) and began implementing a cultural transformation as part of a journey to make Vale one of the safest and most reliable mining companies in the world.
