RhoRho may not be totally off base. There is a group within ISO called the SAG-MSS (Strategic Advisory Group on Management System Standardization.)
"The Strategic Advisory Group on Management System Standardization will provide strategic oversight and advice to the Technical Management Board on evolutions in MSS standardization, and the Joint Technical Coordination Group, which will ensure technical coordination between committees preparing MSS, recommends that the Strategic Advisory Group propose actions to improve ISO’s reach towards the public and private sectors in order to better address trends in management practices, expectations on MSS, and the promotion of the ISO MSS.
The Strategic Advisory Group on Management Systems Standards [is] requested to look into ways to further address ISO’s reach towards the public and private sectors in order to better address trends in management practices, expectations on MSS, and the promotion of the ISO MSS."
As it was descrbed to me, one of the objectives of the SAG-MSS was to look at the possibility, strategy and benefits of integrating quality, environmental and security MSS into one generic, over reaching standard. The SAG-MSS is also to look at the exsistence of sector specific standards, why they exist, what will the future of standards look like, etc. The SAG-MSS has the responsibility of reviewing what MSS are being published, do they meet the needs of the users, where we wil be in the future, where do MSS want to be, what is the vision, etc.
I am in no way an expert on this group or their responsibility, but one person did describe their charter to include an analysis of one integrate MSS.
