Hi, mrwasabi. According to Merriam Webster Dictionary, this is how it is described: the amount of greenhouse gases and specifically carbon dioxide emitted by something (as a person's activities or a product's manufacture and transport) during a given period
Inevitably, in going about our daily lives ? commuting, sheltering our families, eating ? each of us contributes to the greenhouse gas emissions that are causing climate change. That is your personal carbon footprint.
A cute name for the carbon dioxide that you release into the air by burning fossil fuels. It includes stuff you don't see, like petroleum used to produce the consumer goods you buy, or coal burned to produce electricity for your home.
