Is there any possible link for CMIOSH to become CEnv? As we all know, OSH is more related to environment than some engineering areas. Hence IOSH should try to liaise with the Society of Environment so that CMIOSH may become CEnv as well.

There are already long established routes to becoming C.Env (e.g. CIWEM, IEMA, ICE etc). I very much doubt if IOSH could seek to award this qualification, as it's primary role is health and safety and not Environmental matters Some IOSH members have attained the NEBOSH National Certificate in Environmental Management, in recognition of the fact that they are occasionally asked to undertake basic environmental management duties. That is a long way from having the knowledge and experience required of a Chartered Environmentalist. If in doubt have a look at the route to C.Env. PH2
