Probably, after looking at the graphic above, we would say that we prefer the reusable cotton bag, however:
  • cotton-farming process is extremely fossil-fuel-intensive
  • conventionally grown cotton uses more insecticides than any other single crop (according to the Pesticide Action Network of North America)
  • most cotton bags are woven in developing countries where labor conditions are controversial.

Therefore.. probably the best option would be:

d) a reusable tote bag made from recycled plastic

However the best option would probably be the cotton bag if it was made from sustainable cotton like the textiles from DEM COLLECTIVE, a really interesting Swedish textile Brand.
