 Carbon sequestration is the process of capturing atmospheric carbon and, most importantly, storing it for the long term.
-Carbon dioxide (CO2) is the most abundant form of atmospheric carbon. As a “greenhouse gas”, CO2 also plays a major role in contributing to global climate change and is therefore the most common target for carbon sequestration. Carbon sequestration may also target methane (CH4), the second most impactful greenhouse gas in our atmosphere (Forster et al. 2007)((Forster, P, et al. (2007), "Changes in atmospheric constituents and in radiative forcing", Climate Change 2007: the Physical Basis. Contribution of Working Group I to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change.)) . By capturing and storing these gases, this process slows down the accumulation of atmospheric and marine carbon, thereby reducing the rate of climate change.

Carbon sequestration may also target methane (CH4), which is 25 times more climate-effective than CO2((https://www.umweltbundesamt.de/themen/klima-energie/klimaschutz-energiepolitik-in-deutschland/treibhausgas-emissionen/die-treibhausgase)) .

 Carbon sequestration can occur either naturally or as a result of direct human intervention. One example of direct human sequestration is geological sequestration, which involves the capture and subsequent injection of carbon into deep underground reservoirs. Natural carbon storage is often considered an **[[:wiki:ecosystemservices|Ecosystem Services]] (ES) **and is most prevalent in biological processes such as tree growth. For example, by capturing carbon and converting it into biomass, trees effectively sequester carbon until they decay, or are burnt. Furthermore, harvesting of trees for use as a building material can extend the effective length of sequestration, as the carbon is then stored until the building material is destroyed.
