How much negative emissions (DACCS, BECCS, CDR) are needed and under what circumstances can they be generated economically?

To combat climate change effectively, CO₂ capture at point sources in industry and the energy sector is not enough – according to current studies, such as those by the IPCC, CO₂ removal directly from the atmosphere is also crucial.

Various players are therefore developing carbon dioxide removal (CDR) technologies such as Direct Air Capture (DAC) and Bio-Energy Carbon Capture and Storage (BECCS) as well as nature-based methods to generate negative emissions. Scenario-based and techno-economic analyses help to precisely assess the demand, potential and costs of these methods and to determine how and to what extent CDR technologies should be used.
