The Diário do Rio de Janeiro has an editorial board made up of people from various branches of civil society whom the company has entrusted to answer questions about journalistic ethics, the writing manual, plurality and democracy.

The board may be called upon to give an opinion on material submitted for publication, give suggestions on the editorial line and even suggest topics to be dealt with, as well as analyze from the point of view of the requesting person whether there was a mistake by the vehicle in publishing a certain story or piece of information.

The Diário do Rio editorial line is based on independence and respect for plurality.
