The carbon foot print is debatable, but plastic in the environment is basically there forever, where a paper bag breaks down relatively quickly and natural processes can deal with cellulose.

I'd moved into a house and noticed a plastic bag stuck on a branch high up on a tree. When I moved 11 years later, the bag was still there, showing essentially no signs of deterioration, even after 11+ years of exposure to sunlight and seasons that vary from -35C to +35C.

Paper bags can be used as garbage bags as long as the garbage isn't soup. Mum did it back in the 1960s and 1970s until plastic bags replaced the traditional paper bag. We're both back to using paper bags for garbage.

The last plastic bags that my grocery store used were so thin that they almost always had holes in them and leaked, so there weren't appreciably better in that respect than paper.

I'm old enough to remember that grocery store only had paper bags, and replaced them with plastic bags because we were using too much paper and it was killing all the trees.

Now we're back to paper bags...

No one gives a shit about the carbon footprint of bags. It's negligible.

What matters is the amount of waste produced, and a sizable chunk of that IS made up of bags.

@nathris @Ondergetekende Until it closed a few months ago we had a Zero-Waste bulk food store in town and it was where I got a majority of my non produce items: pasta, dried beans, lentils, nooch, bulk spices. (and they were the only place in town with vean meat alts in bulk like Byond and Impossible).

As a fall-back we go to the regular Bulk Barn type place it has a wider selection and thankfully have started allowing tared u-bring containers again.

Its bit of an art being zero-waste.
