Carbon dioxide is not a pollutant but a naturally occurring, beneficial trace gas in the atmosphere. For the past few million years, the Earth has existed in a state of relative carbon dioxide starvation compared with earlier periods.
More often than not, calculations of carbon footprint only calculate carbon dioxide. However, there is another greenhouse gas, methane, that should also be considered in these calculations. Despite its potency, methane is typically ignored because it accounts for a much smaller percentage of total emissions.
