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

To combat climate change effectively, capturing CO₂ at industrial and energy-sector point sources alone is insufficient. Current studies, including those by the IPCC, emphasize the importance of removing CO₂ directly from the atmosphere. Carbon Dioxide Removal (CDR) technologies, such as Direct Air Capture (DAC) and Bio-Energy Carbon Capture and Storage (BECCS), along with nature-based solutions, are being developed to achieve negative emissions.

Scenario-based and techno-economic analyses are essential tools for accurately evaluating the demand, potential, and costs associated with these methods. Such analyses help determine the optimal strategies for deploying CDR technologies and the extent to which they can contribute to meeting climate targets.
