An unpublished Government report shows us that the plastic carrier bag may be an environmental hero rather than an Eco villan.
The report in question "Life Cycle Assessment of Supermarket Carrier Bags" reveals that the Eco warriors bag of choice the cotton bag may be a wolf in sheep's clothing, with HDPE carrier bags which have a baseline global warming potential of 1.57kg, reducing to just 1.4kg after one re use, the report shows that you would have to use your cotton bag 131 times for it to emit a similar level of CO2 equivalent to HDPE plastic carriers bags and after just reusing your carrier bag once this increases to 171.
With the current situation in Wales that has seen the Welsh Assembly pass a compulsory charge of 5p per carrier bag onto its retailers, this report could not have come at a better time, it highlights the fact that all packaging material has an environmental impact but the key is to either re use your plastic carrier bags in what ever way possible, for example as a bin liner or if you are sticking with your cotton bag you need to make sure you use it over and over again.
