Premier League clubs have unanimously agreed new measures to address the "unacceptable rise" in anti-social behaviour last season.
Such behaviour included gesturing, graffiti and online abuse, but in particular, 'tragedy chanting'.
The decision was made at the league's annual general meeting on Wednesday.
The measures "will focus on criminal prosecution, the regulatory environment, enforcement, online abuse, education and communications".
In a joint statement in March, Liverpool and Manchester United managers Jurgen Klopp and Erik ten Hag called for an end to 'tragedy chanting'.
Their fans have chanted about the Munich air disaster and the Heysel and Hillsborough tragedies.
