Toward Stabilization of Net Global Carbon Dioxide Levels

Friday, February 17, 2012: 1:30 PM-4:30 PM
Room 114-115 (VCC West Building)
One of the most pressing challenges facing the global community is stabilizing carbon dioxide emissions by the middle of the 21st century. While the long-term solution will require replacing fossil fuel–based sources with carbon neutral energy sources, the shorter-term remedy will require managing carbon dioxide through capture and storage. A need also exists to compare the efficiency of sequestering carbon (and the concomitant use of energy) versus first limiting its use. Given the magnitude of the problem, all possible strategies for sequestration of carbon dioxide will need to be pursued. This panel will discuss the implications for increasing atmospheric carbon dioxide concentration and the state-of-the-science in terms of mitigating the anticipated increases of atmospheric carbon dioxide emissions through ocean, deep geologic, mineral carbonation, and terrestrial sequestration strategies. While the soil resource has been a source of carbon dioxide as a result of land-use changes and agricultural management practices, it can also serve as a widely distributed sink with implementation of proper restoration and management practices, with the potential to sequester up to 15 percent of current annual emissions. This session aims to provide a clear understanding and comparison of the attributes of the various sequestration strategies, including their capacity, economics, risks, application time-scales, and long-term stability. Of special importance are their policy implications.
