I’ve seen this also and have not seen any evidence to the contrary. Considering how damning this study is to plastic bag bans, I’m guessing this means there aren’t any studies that rebut these findings.



So we need studies now to tell you to occasionally clean the bags you put raw meat into?


That’s one way to interpret the results. Alternatively, the study shows that in the normal course of human behavior, plastic bag bans may have nontrivial negative health impacts.

Also, it shows that in considering the carbon footprint of reusable bags, we should factor in regular (not occasional) cleaning.

Considering that a reusable bag needs to be reused many (hundreds, if memory serves) of times before reaching carbon neutrality versus single use plastic bags, this is not necessarily a trivial impact.


Carbon neutrality is not the only metric by which we create these regulations. Nor should it be. Single-use bags introduce many externalities that are captured and controlled by imposing a minimal cost.


No one said it is the only metric. But it is a relevant one.
