These approaches have been garnering new attention as the international community has identified lower thresholds for global temperature increases, which can only be accomplished with net negative carbon emissions to the atmosphere. However, many of these CDR technologies are not yet viable in terms of cost and scalability, and any potential risks that deployment of these techniques would entail are not fully understood. The proposed study would aim to develop a detailed research and development agenda needed to assess the benefits, risks, and sustainable scale potential for carbon dioxide removal and sequestration approaches; and increase their commercial viability. Statement of Task An ad hoc committee will conduct a study to: 1. Identify the most urgent unanswered scientific and technical questions needed to: 1. assess the benefits, risks, and sustainable scale potential for carbon dioxide removal and sequestration approaches; and 2. increase the commercial viability of carbon dioxide removal and sequestration; 2. Define the essential components of a research and development program and specific tasks required to answer these questions; 3. Assess the costs and benefits of such a research and development program to the extent possible in the timeframe of the study. 4. Recommend ways to implement such a research and development program. The list of CDR approaches to be examined would include land management, accelerated weathering, bioenergy with capture, direct air capture, geologic sequestration, blue carbon approaches, and other approaches deemed by the study committee to be of similar viability.
