I've often noticed that the Migros sustainability scale doesn't "add up" when meat scores (almost) as well as bread or something... So I don't even pay attention to it, but it's definitely greenwashing or simply based on nonsensical criteria.
Wasn't the topic here once how nonsensical the thing is because, for example, things from the region are not all recorded and others from overseas make good ratings? Finds a waste of working time from the person who has to embed all this in this incomplete, falsifying system, which could be invested, for example, in writing in the product information for new products. Or cover the "excessively expensive effort" when a product flies out with it (i.e. copy one click with product name, insert one click into a list, update third click and publish😉).
I don't look at this sustainability scale either, or at the beginning I did it out of curiosity, only to realize that it's pretty "crap"... I agree with you; I think it would be better if Migros invested this effort to correctly record all products online on the website (ingredients, nutritional values, availability in the stores, etc.).
