We introduced a 5 pence charge on the supply of new single use carrier bags on 1 October last year. The aim of this charge is to substantially reduce the number of single use carrier bags supplied in Wales and create a real behaviour change, where taking reusable bags to the shops is the norm. Information from other countries around the world, already charging for carrier bags, showed us that only by introducing a charge could we substantially reduce the number of bags supplied and help towards our goal of becoming a zero waste nation.
