> When I raise it in meetings etc, I get quite a lot of positive responses but no concrete action.
Responding to this generally rather than in the full context, but my recommendation for this situation in general is that you should come to the meeting already knowing what concrete action you'd like to take and then seek buy-in. Ideally you should aim to end the meeting with some specific action items assigned to individuals, but at least you should have gained enough information so that the next time you meet you can push for specific actions to be taken.
