The calculations can be computed ranging from a single person to the entire world. A greenhouse gas footprint is the numerical quantity of these gases that a single entity emits. The most common GHGs are carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2O), and many fluorinated gases. These gases are emitted from fossil fuel usage in electricity, in heat and transportation, as well as being emitted as byproducts of manufacturing. Although some emissions are natural, the rate of which they are being produced has increased because of humans. Greenhouse gases (GHGs) are gases that increase the temperature of the Earth due to their absorption of infrared radiation. However, there are several ways to reduce one's greenhouse gas footprint, choosing more energy-efficient eating habits, using more energy efficient household appliances, increase usage of fuel efficient cars, and saving electricity. Due to humans' heavy reliance on fossil fuels, energy usage, and constant deforestation, the amount of greenhouse gas in the atmosphere is increasing, which makes reducing a greenhouse gas footprint harder to achieve. Climate change has been occurring since the start of the Industrial Revolution in the 1820s. The major effects of such practices mainly consist of climate changes, such as extreme precipitation and acidification and warming of oceans.

These increase the earth's temperature and are emitted from fossil fuel usage in electricity and other byproducts of manufacturing. Human activities are one of the main causes of greenhouse gas emissions.

The global average annual carbon footprint per person in 2014 was about 5 tonnes CO 2e. Calculated as carbon dioxide equivalent using the relevant 100-year global warming potential (GWP100). For this reason, Wright, Kemp, and Williams proposed the following definition of a carbon footprint:Ī measure of the total amount of carbon dioxide (CO 2) and methane (CH 4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system or activity of interest. In most cases, the total carbon footprint cannot be calculated exactly because of inadequate knowledge of data about the complex interactions between contributing processes, including the influence of natural processes that store or release carbon dioxide. 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, wood, roads, buildings, transportation and other services.

The carbon footprint explained Part of a series aboutĪ carbon footprint is the total greenhouse gas (GHG) emissions caused by an individual, event, organization, service, place or product, expressed as carbon dioxide equivalent (CO 2e).
