Transportation is the second largest contributor to greenhouse gases (after electricity generation). It plays a significant role because the industry relies so heavily on oil. The U.S. Department of Energy says that 98 percent of CO2 comes from fossil fuels, and 96 percent of transportation runs on petroleum. The Department of Energy has set a goal of reducing petroleum use by 20 per cent in large truck by 2050 and expects weight reduction to be a big part of that effort as fleets deploy new trucks and trailers built with weight-saving materials.
