Carbon is a naturally abundant nonmetallic element which forms the basis of most living organisms. Carbon is the fourth most abundant element in the universe, and it plays a crucial role in the health and stability of the planet through the carbon cycle. This cycle is extremely complex, and it illustrates the interconnection between organisms on Earth. Most consumers are familiar with the element, along with numerous forms in which it appears. The atomic number of carbon is six, and the element is identified by the symbol “C” on the periodic table. The structure of carbon molecules is such that the molecules bond readily with a wide range of other elements, forming thousands of compounds. The molecules in carbon also bond with each other in different ways, creating forms of carbon such as diamonds, the hardest substance on Earth, and graphite, one of the softest materials on the planet. The changing personality of carbon, depending on what it bonds with and how, makes it a very unique element.
All living organisms contain carbon, and as they decay or change, they will continue to contain the element. Coal, limestone, and petroleum, for example, are all fossilized forms of living organisms containing abundant amounts of carbon. Plants and animal life which died millions of years ago were slowly compressed into these substances, and their integral carbon was preserved. This residual carbon is used in everything from jet fuel to children's dolls.
A Carbon Footprint is "the total set of greenhouse gas (GHG) emissions caused by an organization, event, product or person". For simplicity of reporting, it is often expressed in terms of the amount of carbon dioxide, or its equivalent of other GHGs, emitted. The concept name of the carbon footprint originates from ecological footprint discussion. The carbon footprint is a subset of the ecological footprint and of the more comprehensive Life Cycle Assessment (LCA). An individual's, nation's, or organization's carbon footprint can be measured by undertaking a GHG emissions assessment. Once the size of a carbon footprint is known, a strategy can be devised to reduce it, e.g. by technological developments, better process and product management, changed Green Public or Private Procurement (GPP), carbon capture, consumption strategies, and others. The mitigation of carbon footprints through the development of alternative projects, such as solar or wind energy or reforestation, represents one way of reducing a carbon footprint and is often known as Carbon offsetting.
