Who is certifying the certifiers?

This was sent as a comment but clearly the moderator did not like the questions we asked!! “How can a “Green” certification call itself “third party” if the salesman / owner (or his employees) are the auditors?? Prior to this new joint venture Green Globe used recognized auditing firms – now it is the same company who sells the certification that is doing the auditing. Secondly – how many of these “auditors” are themselves certified / qualified?? Surely this practice is questionable??”
