Btu or 0.5 metric ton of SO2 per 1012 J), emissions will be 386.3 × 106 and 840.5 × 106 (350.4 × 106 and 762.3 × 106 metric tons), respectively, for the two different assumptions about energy supply.

Regional emissions of heat will be concentrated in the densely populated regions of the United States, U.S.S.R., Western Europe, and Japan. Carbon dioxide and particulate emissions will originate in these same areas but will be dispersed relatively quickly. The rate at which these emissions (heat, carbon dioxide, and particulates) will be dispersed and removed from the atmosphere, and the effect on climate are discussed in the following papers.
