@Gamanit where are you pulling your statistics out of?
Uk Goverment did a study on the environmental impact of the production of various bags. The results of which concluded, based off emissions alone you’d need to a reuseable bag use these alternatives this many times to make it more environmentally friendly then a single use bag:
Paper Bags: 4 Times
Polypropylenes: 14 Times
Cotton: 173 Times
This doesn’t take into account the waste impact of multiple bags vs single, reusable bags.
