Fossil fuels without CO₂ emissions

E. A. Parson and D. W. Keith

The climatic impact of fossil energy can be reduced by separating the resulting carbon and sequestering it away from the atmosphere. Recent work in carbon management (CM)–the linked processes of separating and collecting carbon and sequestering it in the ocean or ground– has shown substantial progress in developing the necessary technologies and in understanding the potential for sequestration. One large-scale project for sequestering CO₂ is operational; several others are planned. However, CM’s technical progress is outpacing consideration of its limitations and potential risks. We sketch recent technical developments in CM and discuss its implications for the policy and politics of global climate change.
