Abstract
By comparing and evaluating carbon management systems, including DAC, carbon consumption, and mitigation strategies, this study addresses the escalating quantities of atmospheric CO2 that are contributing to climate change. We evaluate each technology based on its technical sophistication, economic feasibility, and environmental impact using a multi-criteria decision-analysis (MCDA) approach. The assessment approach comprehensively evaluates the advantages and disadvantages of each strategy by utilizing quantitative data and expert commentary. The results indicate that no single technology is capable of achieving all of the carbon mitigation objectives. Consequently, a portfolio-based approach is necessary. The results of this study can be utilized by researchers, policymakers, and corporate executives to identify and implement carbon management strategies that promote sustainable development and mitigate climate change.
