An exact number is impossible. That does not mean plastic bags and co2 are not a huge problem.

Makes great sense to get them nailed down as they were being promoted as the fact on twitter when I saw them. Hey and if they can't be nailed down why even publish them... right? Espcially if they are used to encourage us to buy your bags in good faith. Terra Choice (an environmental marketing firm) wrote a great piece called the six sins of greenwashing (see link below) that talks about 1) hidden trade-off 2) no proof 3) vagueness 4) irrelivence 5) lesser of two evils 6) fibbing http://www.terrachoice.com/files/6_sins.pdf All companies involved in environmental marketing and products need to take care as they are risking jading consumers as we begin to ask for more and more proof. Have a great evening and thanks for reviewing these claims Thanks. Makes great sense to get them nailed down as they were being promoted as the fact on twitter when I saw them.

All companies involved in environmental marketing and products need to take care as they are risking jading consumers as we begin to ask for more and more proof.

Have a great evening and thanks for reviewing these claims

There are many studies on this issue, however the exact numbers are hard to nail down due to many variables, including who is conducting the research. We will look into this and update the info accordingly. Hi “Just Saying”, Thanks so much for sharing your information.

Just two activists with a personal website creating figures to support their personnal goals. I thought the numbers seemed HUGE (highest numbers were highest claim seen to date.) They were very suspect since no methods were posted on the activist site, no instutional support of their report or peer review of the data. To help with your claims... I did find a LCA conducted by BOUSTEAD CONSULTING & ASSOCIATES by an industry group and it states that actually there was only 3g of natural gas used per plastic bag made with paper bags requiring 7.4g. Plastic bags generated only 4.7g of landfill waste if disposed of vs. 33.6g for a paper bag. HDPE plastic bag only generated .00004 ton CO2/bag (about .08/lb) in its life cycle while paper .00008 ton CO2/bag and compostable plastic bags generated about .00012 ton CO2/bag The study I found was peer reviewed by Dr. Michael Overcash, of North Carolina State University and conducted to ISO 14040 standads and was found at http://www.americanchemistry.com/s_plastics/doc.asp?CID=1106&DID=7212 Have a super day!

That is what it says right on the bag I am looking at? Could you provide a link to your study to help clarify the claim of CO2 emmissions and oil used per bag? Would be great to have access too. I have been researching on the internet and its turned out that most sources so far had no real study behind their green claims so it would be great see a report released. If you dont actually have a report I would understand since there are so many myths out there. Arent plastic bags made of HDPE anot PET or LDPE?
