Carbon capture may refer to:
*
Carbon capture and utilization
Carbon capture and utilization (CCU) is the process of capturing carbon dioxide ( C O2) to be recycled for further usage. Carbon capture and utilization may offer a response to the global challenge of significantly reducing greenhouse gas emission ...
, where the captured carbon dioxide is used
*
Carbon sequestration
Carbon sequestration is the process of storing carbon in a carbon pool. Carbon dioxide () is naturally captured from the atmosphere through biological, chemical, and physical processes. These changes can be accelerated through changes in lan ...
, where the captured carbon dioxide is stored
**
Carbon capture and storage
Carbon capture and storage (CCS) or carbon capture and sequestration is the process of capturing carbon dioxide (CO2) before it enters the atmosphere, transporting it, and storing it (carbon sequestration) for centuries or millennia. Usually th ...
, referring to carbon sequestration from point sources
**
Carbon dioxide removal
Carbon dioxide removal (CDR), also known as negative emissions, is a process in which carbon dioxide gas () is removed from the atmosphere and sequestered for long periods of time. Similarly, greenhouse gas removal (GGR) or negative greenh ...
, referring to carbon sequestration from the atmosphere
*
Direct air capture
Direct air capture (DAC) is a process of capturing carbon dioxide () directly from the ambient air (as opposed to capturing from point sources, such as a cement factory or biomass power plant) and generating a concentrated stream of for sequ ...
, where carbon dioxide is captured directly from air
