Okay, after helping derail this thread I now feel obliged to post something on-topic

I'd tend to think that this type of certification is something that would need to be driven by government demands. I look at it like first aid training; corporations and other groups operating in certain spaces need to have a dictated amount of certified first aiders. This provides the motivation for the standards & levels of certification to be set and then multiple players in the training space can develop programs that meet those standards in whatever way they feel best for their target customers (for example, my wilderness first aid certification is accepted by provincial authorities to be equivalent to or surpassing Standard First Aid).

That said, there are other disciplines, like IT (my field), where there are various technical certifications which can take off but only if both the individual and (more importantly) employers believe that it is beneficial for the individual to hold such a certification. Personally, I don't believe such certifications are good indicators of skill so I don't value them highly; though I have recently got more but simply because it helped our company from a corporate partnership perspective.

To get a wilderness survival certification off the ground from this non-government mandated perspective, it would require some really good marketing to get the corporate buy-in to create the demand (I think, at least).
