It also takes energy to make a cotton bag, but you only make it once and re-use it many times. The raw material is pretty close to carbon-neutral.

Quote:quote:Reducing plastic bags is a litter issue NOT a climate change issueNot so - plastic bags are made from oil. It takes energy (= greenhouse gas emissions) to extract and transport the oil, to refine it into the raw materials for plastic bag manufacture, and to make and distribute the bags themselves. There are also waste gasses produced during all of those stages. The bags then decay (albeit very slowly), releasing more gasses.
