Billion metric tons/year of carbon Figure 6 Carbon Emissions Under the OTA NOTE: The boxes outlined with dashed lines represent the reductions in carbon emissions associated with control measures applied in each of the three demand-side sectors (i.e., buildings, industry, and transportation) and electricity supply (electric utilities); additional carbon offsets afforded by forestry measures are also shown. The boxes outlined with solid lines represent total emissions from each demand-side sector. For the solid boxes, emissions associated with electricity generation have been allocated to the three demand-side sectors. SOURCE: Office of Technology Assessment, 1991. |
