Technologies that aim to reduce the amount of carbon dioxide in the atmosphere, either by directly removing it or by reducing emissions from various processes.
Carbon capture and storage
(Carbon Capture and Storage, CCS)
This technology captures carbon dioxide emissions from industrial processes and power plants and stores them permanently in geological formations deep underground. This prevents the carbon dioxide from being released into the atmosphere and helps reduce emissions.
Bioenergy with carbon capture and storage
(BECCS)
A combination of renewable energy and carbon capture. Biomass, such as wood or other plant materials, is used for energy production. When the carbon dioxide released during combustion is captured and stored, it results in a 'negative' emissions technology, meaning that more carbon dioxide is removed from the atmosphere than is emitted.
Direct air capture
(Direct Air Capture, DAC)
This technology removes carbon dioxide directly from the air using chemical processes. The captured carbon dioxide can then either be permanently stored underground or used in various products, such as fuels, building materials or chemicals.
