<P> Carbon dioxide removal ( CDR ) refers to a number of technologies , the objective of which is the large - scale removal of carbon dioxide from the atmosphere . Among such technologies are bio-energy with carbon capture and storage , biochar , ocean fertilization , enhanced weathering , and direct air capture when combined with storage . CDR is a different approach than removing CO from the stack emissions of large fossil fuel point sources , such as power stations . The latter reduces emission to the atmosphere but can not reduce the amount of carbon dioxide already in the atmosphere . As CDR removes carbon dioxide from the atmosphere , it creates negative emissions , offsetting emissions from small and dispersed point sources such as domestic heating systems , airplanes and vehicle exhausts . It is regarded by some as a form of climate engineering , while other commentators describe it as a form of carbon capture and storage or extreme mitigation . Whether CDR would satisfy common definitions of `` climate engineering '' or `` geoengineering '' usually depends upon the scale on which it would be undertaken . </P>
