This evaluation has shown that the policy is popular and effective.

The charge has helped to increase own bag use in Wales (from 61% to 82%). This is consistent with findings from other countries where a similar charge has been introduced.

While the study also showed an increase in own bag use in England, where no carrier bag charge was introduced, the increase was greater in Wales.

The study shows that the charge is widely supported in Wales. Even before its introduction, the charge was supported by a majority of the Welsh population (59%). Support for the charge increased even further after its introduction to 70%.
