This Intergovernmental Panel on Climate Change special report describes sources, capture, transport, and storage of carbon dioxide (CO₂), and it discusses the costs, economic potential, and societal issues of the technology, including public perception and regulatory aspects. This report shows that the potential of CO₂ capture and storage is considerable, and the costs for mitigating climate change can be decreased compared to strategies where only other climate change mitigation options are considered.
