What is carbon sequestration or offsets?
Sequestration is capturing and permanently storing carbon dioxide to reduce the amount in the atmosphere. This is done naturally through oceans and growing forests. There are now man made systems of capturing and storing carbon. Carbon can be mixed with metal oxides to form carbonates, these become liquids or solids and can be easily stored. Additionally, carbon can be directed injected into underground geological forms (geosequestration). Ocean storage has also been proposed.
