Sadly, having more reusable bags than you need can result in producing even more single-use plastic. From the article New Jersey Bag Ban Followed By Increased Use Of Plastic:

the reusable bags New Jersey shoppers have been forced to use since the bag ban took effect in May of 2022 are rarely reused, only two to three times on average. With many people in New Jersey now using reusable bags as single use bags, the state’s plastic and paper bag prohibition, though passed with the best of intentions, may be doing more harm than good in practice.

Reusable bags are manufactured with 15 to 20 times the amount of plastic used in the now prohibited single-use plastic bag, notes the Freedonia report. The reusable bags that New Jersey residents now pay for at checkout or when their groceries are delivered, according to researchers, need to be used anywhere from 11-59 times in order to have a net benefit for the environment.

Though I would like to note that New Jersey made the stupid decision to not only ban plastic bags, but to ban paper bags too. It’s a move I can’t understand, except to assume that there’s some corrupt lobbying behind such a stupid decision. If the point is to be environmentally friendly, it makes much more sense to use a renewable source like paper.
