It is believed that increases in carbon dioxide concentration will be largely irreversible for 1,000 years after emissions stop (Solomon 1). Atmospheric carbon dioxide concentrations increase from current levels near 385 parts per million by volume (ppmv) to a peak of 450–600 ppmv over the coming century. Carbon dioxide is emitted into the atmosphere through transportation, as well. The combustion of fossil fuels such as gasoline and diesel to transport people and goods is the second largest source of CO2 emissions, accounting for about 31% of total US (EPA
