Well it almost exists. Certificates contain fields referencing the procedures that have been used to deliver them. The main problems are: who cares? and who could be the authority validating that a company is a well behaving one.
I shall just take a real world (non IT world) example: boat flags. A number of countries decided to require a number of controls on their own boats and ask the boat owners to pay for that. And some countries decided to simply ask less money. Panama is certainly a nice country but has a number of boats per inhabitant extremely high...
If you just require a company to find a country to validate it, the same causes will certainly produce the same outcomes: most company will ask the country requiring less money, and that will certainly the country using the less controls.
Of course, USA or UE have enough importance in world economy to be able to setup "labels". But that also mean either a number of agents to control even the smallest company, of the label has to be restricted to a small subset, which is incompatible with the liberal economy.
That being said, UE has setup legal rules for what is required for an electronic signature to have the same legal value as a handscripted one. Simply certificates having that level are rather expensive because every step involved in the delivery has to be traced, and the identity of the owner must be verified in a face-to-face procedure. And I must acknowledge that I have seldom seen those kinds of certificates, except in governmental procedures, probably because of their cost...
Finally the major problem is who could be interested in such labels and who is able to setup them. End clients would certainly be interested but they cannot handle the required organization. Large international companies would certainly both be interested and have the capacity, but the immediate result would be to prevent any smaller company to use internet for their business, and legal authorities of USA and UE would forbid that. Or the alternative would be a higher cost for the organization of the label at the point that they find better not to set it up.
