In California you pay an extra deposit when you buy a plastic bottle. I don’t know if that number is set to properly capture the externality, but it’s enough to get people wandering the streets to pick up the bottles and turn them in (they even rifle through your trash can). Also, it doesn’t apply to most forms of plastic packaging or goods.
