CARBON DIOXIDE EQUIVALENTS
The root cause of climate change is the release of man-made greenhouse gases into the atmosphere resulting in trapped heat. The most important greenhouse gases are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Due to the varying ability of greenhouse gases to trap heat in the atmosphere, some are more harmful to the climate than others. Each greenhouse gas has a “global warming potential” (GWP), which refers to its heat trapping potential relative to that of CO2. Therefore, to provide a comparable final figure, in our carbon footprints all emissions are reported as a relative figure to CO2, i.e. as CO2e values.
