Abstract: The projections of energy related carbon dioxide (CO₂) emissions in the Special Report on Emission Scenarios (SRES) of the Intergovernmental Panel on Climate Change (IPCC) serve as point of departure for an assessment of plausible ranges of CO₂ emissions that could be avoided through CO₂ capture and storage measures. Scenario and time dependent, sector and fuel specific capture factors are developed for eleven world regions to estimate the proportion of CO₂ resulting from fossil fuel and biomass combustion/conversion that might be practical to capture and store. The capture factors are applied to the original CO₂ emissions scenarios at a highly disaggregated level. The results are summed up and presented. The results indicate that it might be possible to capture and store a significant quantity of energy related CO₂, especially in the second quarter of this century. Yet the amounts of CO₂ still being emitted remain considerable, suggesting that other technologies will also be needed if the threat of climate change requires large reductions of CO₂ emissions over the next few decades.
