The UK introduced a carrier bag charge scheme. Overnight usage dropped 80%, and that was for a 5p charge. Now I don't think many people would stop to pick up 5p off the street, but people will jump through the hoops to avoid paying the 5p. These things work, even at a relatively low threshold. Don't forget you're only aim to nudge what people know they should already be doing.
