In fairness, the article itself doesn't mention climate effects, just the following, which I read as implying that voluntary reduced use of single-use plastic bags has had a material anti-litter effect, so the law should have an even greater anti-litter effect:
> According to the Mercury News, the number of plastic bags picked up at California beaches during the state’s annual Coast Clean Up day dropped by 61% from 65,736 to 25,768 by 2019.
I'm not claiming that proponents didn't primarily highlight climate, I don't know, I'm just going off this article where it's not even mentioned (yet practically all the comments seem to revolve around this being an ineffective climate measure).
