Carbon footprint - Wikipedia

A carbon footprint is the total greenhouse gas (GHG) emissions caused by an individual, event, organization, service, or product, expressed as carbon dioxide equivalent. Greenhouse gases, including the carbon-containing gases carbon dioxide and methane, can be emitted through the burning of fossil fuels, land clearance and the production and consumption of food, manufactured goods, materials ...

While increasing soil organic carbon is normally a slow (decadal) process and inputs must be sustained to maintain any changes, measuring carbon stocks allow us to monitor changes through time. Soils often experience changes in bulk density (BD) over time, so it is necessary to adjust any carbon stocks to an equivalent soil mass.
