FIGURE D.20 Major influences on the simulated GHG emissions for the U.S. LDV fleet in 2050.

consumption of such vehicles is also a significant contributor. Scrappage is another strong contributor because it helps set the rate at which new technology penetrates the fleet. Because plug-in and HEVs are not expected to be a significant fraction of the fleet in this work, assumptions about their sales and the emissions from the grid are much less significant to future scenarios than VMT or well-to-wheels emissions from gasoline.
