Nope, wrong. Manufacturers need to use EPA-Recognized Certification Bodies (CBs) and Laboratories.
All ENERGY STAR certified products are subject to post-market verification testing (VT) administered by CBs, irrespective of when they were initially certified. Brand owners must be responsive to CB requests for information and payment for this testing.

So yes, it is independent, neutral, and consistent. I can't say that every single test at every single lab is perfectly executed, but there is no evidence whatsoever of wide-spread flaws in the Energy Star program.
