IPCC Special Report on Carbon Dioxide Capture and Storage Edward S. Rubin Carnegie Mellon University, Pittsburgh, PA Presentation to the U.S. Climate Change Science Program Workshop Washington, DC November 14, 2005 Structure of the Intergovernmental Panel on Climate Change (IPCC) About IPCC Reports Provide assessments of scientifically and technically sound published information No research, monitoring, or recommendations Authors are best experts available worldwide, reflecting experience from academia, industry, government and NGOs Policy relevant, but NOT policy prescriptive Thoroughly reviewed by other experts and governments Final approval of Summary by governments History of the Special Report 2001: UNFCCC (COP-7) invites IPCC to write a technical paper on geological carbon storage technologies 2002: IPCC authorizes a workshop (held November 2002) that proposes a Special Report on CO2 capture and storage 2003: IPCC authorizes the Special Report under auspices of WG III; first meeting of authors in July July 2003–June 2005: Preparation of report by ~100 Lead Authors + 25 Contributing Authors (w/100s of reviewers) September 26, 2005: Final report approved by IPCC plenary December 2005: Will be presented officially to UNFCCC at COP-11 Why the Interest in CCS? The UNFCCC goal of stabilizing atmospheric GHG concentrations will require significant reductions in future CO2 emissions CCS could be part of a portfolio of options to mitigate global climate change CCS could increase flexibility in achieving greenhouse gas emission reductions CCS has potential to reduce overall costs of mitigation CO2 Capture and Storage System Structure of the Report 1. Introduction 2. Sources of CO2 3. Capture of CO2 4. Transport of CO2 5. Geological storage 6. Ocean storage 7. Mineral carbonation and industrial uses 8. Costs and economic potential 9. Emission inventories and accounting Key Questions for the Assessment Current status of CCS technology? Potential for capturing and sto
