When we read, hear and talk about climate change, a certain activity or product's carbon footprint is often mentioned. It's all well and good to know what is the carbon footprint of the production of that water bottle you are drinking from, but how is this actually worked out? Have you ever considered calculating your individual carbon footprint?
Well, according to Time for Change, there is a way to measure the carbon dioxide that you emit from your own personal use of plastic bags.
The footprint of LDPE or PET (polyethylene) plastic is approximately 6kg of carbon dioxide per kilogram of plastic. So, to calculate the amount of carbon dioxide you emit from your annual usage, multiply the weight of your plastic bags by the number of plastic bags you use per year.
