| − | The '''carbon footprint''' is the estimation of [[carbon dioxide]] (CO<sub>2</sub>) from human activities that supposedly have an impact on [[climate change]], notably the burning of [[fossil fuels]] that release [[greenhouse gases]] into the atmosphere. Typically, one's so-called carbon footprint is calculated by evaluating the amount of time a person spends traveling in various vehicles; how much electricity, natural gas, fuel oil, etc. they use in their home; what they do, eat, wear, and buy; whether or not they practice [[environmentalism]] (e.g. [[recycling]]); and what country they live in. This calculation is then used to determine what someone has to do to "offset" their carbon footprint. This almost always involves paying exorbitant amounts of money to companies that supposedly plant trees or build alternate energy producing facilities. | + | The '''carbon footprint''' is the estimation of [[carbon dioxide]] (CO<sub>2</sub>) released into the atmosphere by human activities that supposedly have an impact on [[climate change]], notably the burning of [[fossil fuels]] (see [[Greenhouse gases]]).
