Negative carbon dioxide emission
Encyclopedia
A negative carbon dioxide emission or negative emission is a permanent removal of the greenhouse gas
carbon dioxide
from the atmosphere. It is considered the direct opposite of carbon dioxide emission, hence its name. It is the result of carbon dioxide removal technologies, such as bio-energy with carbon capture and storage

Greenhouse gas
A greenhouse gas is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in the Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone...

Bio-energy with carbon capture and storage
Bio-energy with carbon capture and storage is a greenhouse gas mitigation technology which produces negative carbon emissions by combining biomass use with geologic carbon capture and storage....
, biochar
Biochar
Biochar or terra preta is charcoal created by pyrolysis of biomass. Biochar is under investigation as an approach to carbon sequestration via bio-energy with carbon capture and storage. Biochar thus has the potential to help mitigate climate change, via carbon sequestration...
, direct air capture or enhanced weathering
Enhanced weathering
Enhanced weathering refers to chemical approach to geoengineering involving land or ocean based techniques. Examples of land based enhanced weathering techniques are in-situ carbonation of silicates. Ultramafic rocks, for example, have the potential to store 500 years worth of production according...
