The difference in plastic bag consumption in the UK after supermarkets put a £0.05 fee on them.

Logical mind would say people reduced carrier bag use to keep the £0.05

Psycho-logical mind would say £0.05 acted as a signal of guilt

People drop £0.05 on the floor and don't care if they can't pick it up.

You literally can't buy anything with £0.05 in a supermarket in 2019.

Yet it's reduced plastic bag consumption by 90%.

What a powerful habit change

A £0.05 negative reminder can change a whole nations behaviour + do wonders for the enviroment
