Pay me for every plastic bag I don’t use
While I don’t particularly like the ban on plastic bags (because I use them) I do understand it. However charging for a bag isn’t going to make me run out and buy reusable ones.
But if I were paid for every bag I didn’t use, I might. Doesn’t need to be a big amount, just a few cents. But it will add up over time and I can not only feel like I am helping the environment, but that I am being paid to do it.
