The manufacturers can provide that long description if the customers want it. I think the simple color-coded report card is a great way for people who don’t buy appliances often to compare energy use in models. Brussels seems not to have anticipated that equipment would continue improving, so the original A to G scale was expanded up to A+++ and ratings below D were “virtually empty.”

[Trigger warning: “Implicit consent was working admirably”, but .eu sites often take two cookie clicks.]

Eventually customers would have to take the log of the number of plus signs after the A, so they are switching back to A-G, and during the transition customers see two labels with different scores on the same machine. Surely you agree this is confusing? Under the new scale, it is expected that no appliances will score an A, leaving that space open to future improvements, until it eventually becomes crowded.

Why not recalibrate the scale every year, instead of waiting until the scale becomes useless? Customers could quickly compare new models without consulting a database or studying physics.
