A carbon footprint is typically calculated by estimating the greenhouse gas emissions caused by an activity, and then converting those emissions into a CO2e value. This value takes into account not only CO2 emissions, but also other greenhouse gases such as methane and nitrous oxide. In some cases, other types of climate impacts are also included in the calculation, such as vapour trails from aeroplanes.

The resulting carbon footprint value can then be used to understand the climate change impact of the activity in question, and to compare it with other activities. For example, a product with a high carbon footprint would have a greater climate change impact than a product with a low carbon footprint.

There are many different methods for calculating carbon footprints, and the most appropriate method will depend on the activity being considered. For example, a simple calculation might be used for estimating the carbon footprint of a car journey, while a more complex calculation would be needed to estimate the carbon footprint of producing a widget.

In general, carbon footprint calculations require a good deal of data and can be quite complex. However, there are many online carbon footprint calculators available that can provide a quick and easy way to estimate the carbon footprint of activities such as driving, flying, or consuming certain products.
