A run scored on a hit, walk or steal, without benefit from a defensive error on the play.

A run scored without the benefit of an error.

A run that is charged to the pitcher and is scored without the aid of an error, passed ball, obstruction, or catcher's interference.

A run for which the pitcher is held accountable ( see Rule 10.18).

In baseball, an earned run is any run for which the pitcher is held accountable (i.e., the run scored as a result of normal pitching, and not due to a fielding error or a passed ball). All others are unearned runs. An error made by the pitcher in fielding his position is counted the same as an error by any other player.
