The traffic light system is used in the UK to show how much sugar/salt/fat is in the product. To be honest it shocked me to see so much red for salt so it definitely was eye opening.
The issue with this, that I can now see, is that it would take government action to make this a requirement. But I can see that there would definitely be a benefit for education the customer.
Dual scale would make it possible to differentiate between two similar products - an "eco" cotton bag could be orange/green while a single plastic use bag could green/red. This way every one would know that an eco bag is worse than a plastic one unless you use it a lot.
Finally, producers would be motivated to optimise environmental impact of all kinds of products because having a red label would be shameful.
