RIO DE JANEIRO, Oct 14 (Reuters) - Brazil's Petrobras

is discussing a partnership with Vale to

help the mining company lower carbon emissions, the state-run

oil firm's Chief Executive Magda Chambriard said on Monday.

WHY IT'S IMPORTANT

The two Brazilian companies are among the largest in Latin

America by market value.

Chambriard said the firms will "help each other"

decarbonize, with a possible deal in which Petrobras would

supply marine fuel and diesel with renewable content for Vale to

run its railways, ships and trucks.

KEY QUOTE

"It's an effort by the two largest companies in Brazil

towards decarbonization," Chambriard told journalists.

BY THE NUMBERS

Petrobras is already able to provide marine fuel with up to

24% of renewable content, and diesel with 5%, said Chambriard.

ADDITIONAL CONTEXT

Both Vale and Petrobras are looking for ways to reduce

carbon emissions from their operations, with Vale resorting to

batteries and renewable energy in its effort.

Petrobras believes it could reach net zero carbon emissions

by 2035, said Chambriard, but maintained that its formal

commitment is still to do so by 2050.
