A study commissioned by DEFRA in 2000, showed that UK consumers used eight billion plastic carrier bags per year. However, it also showed that more than 80 per cent of people in the UK re-use their plastic carrier bags.
(In the Republic of Ireland, by introducing a 15 cent plastax, they cut their use by more than 90% and raised millions of euros in revenue. In Bangladesh polythene bags are banned altogether.
I have a bag for life, but I still get given carrier bags, unless I tell the shop assistant I don’t want one.)
