Sloppy wording on my part. Just that the firms designing equipment could put in the effort to meet efficiency guidelines. To consumers, it is just a label on the product, but I am sure the official testing/validation requirements are some amount of work.

Ah okay. Yes - I agree that each individual firm had to do this work, and should get credit for the progress they've enabled.

But if all of products have this label - what is the point?

It means each company met the standard.
