Environmental considerations of Clean Coal Program (CCP) initially focused on reducing emissions of sulfur dioxide (SO{sub 2}) and nitrogen oxides (NO{sub x}) to the atmosphere. However, it has also become apparent that some Clean Coal Technologies (CCTs) may contribute appreciably to reducing emissions of carbon dioxide (CO{sub 2}), thereby diminishing the rate of any global warming that may result from greenhouse effects. This is particularly true for CCTs involving replacement of a major portion of an existing facility and/or providing the option of using a different fuel form (the repowering CCTs). Because the subject of global-scale climate warming is receiving increased attention, the effect of CCTs on Co{sub 2} emissions has become a topic of increasing interest. The Final Programmatic Environmental Impact Statement for the Clean Coal Technology Demonstration Program projected that with full implementation of those repowering CCTs that would be most effective at reducing CO{sub 2} emissions (Pressurized Fluidized Bed and Coal Gasification Fuel Cell technologies), the national fossil-fuel Co{sub 2} emissions by the year 2010 would be roughly 90% of the emissions that would occur with no implementation of any CCTs by the same date. It is the purpose of this paper to examine the global effect of such a reduction in greenhouse gas emissions, and to compare that effect with effects of other strategies for reducing global greenhouse gas emissions.
