Almost double the amount of plastic is used to make the longer lasting bags – undermining the goal of cutting back on waste as 1.18billion bags were issued last year.
The bags for life are supposed to be used multiple times, but the figures suggest people are using them as single-use carriers.
The average household used 44 new bags for life last year.
According to charity Environmental Investigation Agency:
- Tesco issued 430 million bags for life in the 12 months to the end of June
- Sainsbury’s 268 million
- Morrisons 140 million
- Aldi 52 million
- Co-op 28 million
- Waitrose 22 million
- M&S 14 million
- Iceland 3.5 million
