Define Greenwashing

I can buy these vegan yoghurts here in the shop, which look basically the same. It's not completely stupid, since the plastic inside is genuinely quite flimsy compared to what it's normally like, but every time it has me thinking, they could be selling these in reusable glass jars instead.

Like, that's not even a new concept. There is a non-vegan yoghurt brand that's being sold like that. But that's probably precisely why they don't do. You can't sell it as some revolutionary green thing, if it's always been done like that.
