Paper Carrier Bag Carbon Footprint: 16.6 to 82.9 g CO2e Per Bag, New European Study Shows

New cradle-to-gate data from RISE Research Institutes of Sweden puts the fossil carbon footprint of paper carrier bags at 16.6 to 82.9 g CO2e per bag. The study, commissioned by The Paper Bag platform, covers three common bag types: a 20 g takeaway bag, a 55 g shopping bag with twisted handles, and a 100 g shopping bag with flat handles. Paper production accounts for about 67% of the footprint. The numbers are meant to give retailers and brand owners a baseline for packaging choices, but the scope has limits. It only covers emissions up to the factory gate, excludes bags with high recycled content, and does not compare paper bags with plastic or reusable alternatives. The car travel equivalences based on German 2024 data help put the figures in perspective. Retailers comparing packaging options should treat this as a solid starting point, not a full life cycle answer. The methodology is transparent enough to check, and the bag weight and mill energy mix will drive most of the variation.

Interesting to finally have numbers for paper bags in Europe. The range makes sense because bag weight varies a lot. Would be useful to see the same methodology applied to plastic and reusable bags so retailers can compare like for like. The study only covers cradle to gate, so use phase and disposal are left out.

So the smallest bag is 20 g and lands at 16.6 g CO2e. That works out to about 0.83 g CO2e per gram of bag, while the 100 g bag is 0.829 g per gram. Consistent enough. The missing piece is how these numbers compare with a reusable bag after multiple uses, because that is the actual choice most shoppers face.

Cradle to gate is a clear boundary, but it is not the full story. If the goal is informed packaging decisions, retailers also need end of life emissions and a comparison to the plastic bag they are replacing. Without that, the car travel equivalence is just a PR hook.

The 16.6 to 82.9 g CO2e range is basically nothing next to most product footprints, but the bag weight drives it. Paper production at 67% of the footprint means fibre sourcing and mill energy mix are the levers that matter. The industry funding the study is worth noting, but the methodology seems transparent enough to check.

The car travel comparison is a nice touch but it depends on the car and the year. UBA 2024 average for Germany, so fine as a rough anchor. I would like to know which energy mix the mills used, because 2024 grid data can swing the number a lot depending on where the kraft paper is made.
