Carbon sequestration is the process of storing carbon in a carbon pool. [2]: 2248 It plays a crucial role in limiting climate change by reducing the amount of carbon dioxide in the atmosphere. There are two main types of carbon sequestration: biologic (also called biosequestration) and geologic. [3]

The terms carbon capture and storage (CCS) and carbon capture, utilization, and storage (CCUS) are closely related and often used interchangeably. [11] Both terms have been used predominantly to refer to enhanced oil recovery (EOR) a process in which captured CO 2 is injected into partially-depleted oil reservoirs in order to extract more oil. [11]
The biological pump (or ocean carbon biological pump or marine biological carbon pump) is the ocean's biologically driven sequestration of carbon from the atmosphere and land runoff to the ocean interior and seafloor sediments. [1]
A carbon sink is a natural or artificial carbon sequestration process that "removes a greenhouse gas, an aerosol or a precursor of a greenhouse gas from the atmosphere". [2]: 2249 These sinks form an important part of the natural carbon cycle.
Blue carbon is defined by the IPCC as "Biologically driven carbon fluxes and storage in marine systems that are amenable to management." [2]: 2220 Another definition states: "Blue carbon refers to organic carbon that is captured and stored by the oceans and coastal ecosystems, particularly by vegetated coastal ecosystems: seagrass meadows, tidal marshes, and mangrove forests."

Biochar carbon removal (also called pyrogenic carbon capture and storage) is a negative emissions technology. It involves the production of biochar through pyrolysis of residual biomass and the subsequent application of the biochar in soils or durable materials (e.g. cement, tar).
