Not really the same thing but I worked for an organisation which had as a policy that every single team meeting had to have diversity & equality as a recurring item for discussion. 95% of the time this just meant the meeting lead saying "So...diversity - anyone got anything to say?" and then we moved onto the next item after a short silence. But every once in a while someone would raise something that might not have otherwise been brought up. It's a very crude instrument but it probably did get people to think a little more in that direction and maybe led to a little more awareness overall. The other standing item was health and safety which had a similar outcome.
