The major natural sinks of carbon dioxide are oceans, soils and living and dead biomass, mainly plants – including forests. This short information note provides an overview of the potential of soil as a carbon sequestration option. Currently the Clean Development Mechanism, established under the Kyoto protocol, considers only afforestation and reforestation as acceptable sequestration activities. It is suggested that the post-2012 regime would benefit if soil carbon storage could be recognized as an eligible carbon sink in all land use systems, in particular agricultural soils. Indeed, the IPCC (2007) noted that soil carbon sequestration is the mechanism that holds the greatest global mitigation potential.
