See my reply to the other guy above. I was applying the logic (possibly flawed) to how food is sold: 900g of pasta is more food than 750g of pasta, regardless of the difference in packaging. If you need 900g, then you’d need to buy two of the 750g, which is even more wasteful.

But I guess my problem is that they are comparing two different products, in two different quantities (loads per bottle), but linked together with how much plastic and water they use.

They didn’t make the same product with less plastic or water, it’s a new product with the same label.
