Really crummy paper bags for (dry) fresh food isolation, heavier re-usable for takeout and carry. It's nice to have bags to be able to give to others and forget about.
Re-usable produce containers should be sold too, and I'd prefer if those were sold from a special part of the store so that consumers could pack in their own togo containers.

>According to the previously cited U.K. study, it takes three reuses of a paper bag to neutralize its environmental impact, relative to plastic. A bag’s impact is more than just its associated carbon emissions: Manufacturing a paper bag requires about four times as much water as a plastic bag. Additionally, the fertilizers and other chemicals used in tree farming and paper manufacturing contribute to acid rain and eutrophication of waterways at higher rates.

I guess you can argue that paper bags are compostable, but I'm not sure whether that matters much. Plastic bags that are sitting in the landfill doesn't harm the environment, and their bulk is negligible due to how thin/light they are.
The biodegradability of paper bags is the whole point here. You've seen the sides of the roads. You've seen the streams and rivers. People get done with their garbage and just throw it wherever. With garbage made out of plastic that doesn't break down, this is a big deal.
My local rivers are relatively plastic-free. Same with roads. They're not completely free of plastic, of course. Given that there are thousands of plastic bags being dispensed in my neighborhood every day and that the roads/rivers aren't being regularly cleaned, the fact that the neighborhood isn't completely filled with plastic bags makes me think that the overall disposal rate is pretty good.
Plastic litter might be the most visible externality of single use plastics, but I'm not quite sure whether tripling our co2 emissions from plastic bags is a worthwhile trade for eliminating plastic bags from our neighborhoods.
Most of the plastic in the oceans isn't coming from consumer waste[1]. Furthermore, most ocean pollution comes from a few developing countries[2]. Therefore a ban single-use plastics for consumers in developed countries will have little or zero impact on ocean pollution.

That statement might be broadly true, but I doubt that it's accurate for plastic bags.
For china at least, only around 10% of their total waste is imported[1], so blaming it all on developed countries is questionable. The data is from before the ban, by the way.
I'm not sure what you're implying by putting "recycled" in quotes, but they're not definitely taking the plastic and dumping it into their rivers. They're paying us for the plastic[2], not the other way around. Plastic bags can't even be recycled in most jurisdictions, so it's unclear how they'd be imported into those developing countries in the first place.

Failing all of the above, it is unlikely used paper bags end up on barges destined for the developing world for recycling, only to be dumped into the ocean.
Is using petroleum intrinsically bad? There are externalities with oil extraction, but growing a monoculture of trees for paper isn't stellar for the environment either. Also, plastic is stronger than paper (on a mass basis), hence plastic bags can be thinner than paper bags, which also carry advantages. I feel people irrationally like paper bags because it's more "natural" than plastic. It's insufficient to judge whether plastic or paper is better for the environment just by coming up a list of bullet points. A total lifecycle cost analysis is needed. Of the literature I've seen, paper bags are not better for the environment overall than plastic.

Yes. It should be phased out of all use cases, as quickly as possible. We have proven ourselves incapable of being responsible stewards of the resource.
I wonder about supermarket food in particular. Most of it comes in at least one layer of single use plastic - I think plastic can be the right product, but it would need reusable plastics that are standardised and used across different companies products. A bit like how nearly all Chinese takeaways use a variant of a cheap but reusable plastic container (but they're not quite standardised, particularly the radius of the lid corners).
I'd love to see say 20 different allowed packages, you return after use, they're cleaned (or recycled if damaged), and used for more food. No more half full tubs carefully concealed with labels!
I wonder what the stats say vs GPs impressions of Austin?
You do also get whole vegetables in plastic packaging, but there has been a push to remove this. I believe one of the major supermarkets (Morrissons) has recently removed all plastic packaging from fresh produce.
Piece of fruit wrapped in cling film, shrink-wrapped in plastic, tucked into a foam lattice, placed into a styrofoam mold, put in a box, wrapped in paper, then wrapped again by the shop, placed in a small bag that goes into a larger bag.
Even as an American, I never really knew wastefulness until I started going to Japan.
This has been my experience shopping in Austin, but it may vary based on neighborhood. The vast majority bring their own reusable bags. Those that forget to bring bags buy the plastic reusable bags (unless the store also offers free paper bags).
1) What I find it funny is banning plastic bags but at the same time many of the "bio" veggies and fruits come in plastic packaging to prevent contamination and hijacking (sometimes between the producer and consumer non bio stuff is introduced and sold like so)
2) And the funniest thing is that single plastic use is banned in a first world country where most of the food products come from the other side of the world. The CO2 footprint here in Germany is one of the biggest in Europe... Sometimes it feels a bit of green-washing all this news
In Germany, single use plastic bags have not been allowed in supermarkets for several years now and it has worked quite well IMO.
Yes you can buy thicker re-usable bags (sometimes made out of textiles or a mixture of textiles and plastic) but by far many people bring their own bags, or just load the stuff into shopping trollies and take it to their cars (unfortunately the petrol/diesel car culture is still going strong :( ).
Also, in places like Lidl and Aldi, it's quite normal to just look for an empty box of some product on the shelf(e.g. a box that had some canned goods) and use that as your 'basket', stuff your items there, pay, go home and dispose of the box in the paper recycle bin.
EDIT: I also forgot to mention, as an example of culture/attitude: plastic bags are still available for fruit & vegetables but even then, people do make their own choice to just take the produce without a bag, and place it 'loose' at the cashier for them to weigh.
