Reduce waste = good for cost of business, good for the environment...
Lets wait until someone shows how many times those warehouse (or similar) bags get used before replacement, and how much more energy is required to make them in the first place.
Plastic bags are made out of cheap, junk material.. but re-usable bags would be in the order of dozens, if not hundreds (if they're made out of woven material), of times the energy to create so, unless they actually get used at a commensurate rate they are only window dressing in terms of environmental impact.
At a shopping visit per week rough guess a re-usable bag may need to be used for years before it can be said to have had less impact than a plastic bag every week over the same period.
What we should be asking is: why is the collection rate of plastics so behind the 8-ball, and why - since it is available - aren't bio-plastic bags the only ones legally available? (could this be seen as an effort by supermarkets to pre-empt future legislation which would force them to deal properly with the standard plastic bags they supply currently?)
This is window-dressing which will achieve little.
