Commercial transportation presents unique challenges for the development of sustainable transportation, because it requires the distribution of goods across the country.

  • For the time being, delivery trucks and semi-trucks are necessary for the distribution of goods across the country. These large vehicles typically have poor gas mileage and higher emissions than compact vehicles. However, there may be ways to decrease the negative impacts of these vehicles in the future through improvements in efficiency and different fuel sources.

  • Medium and heavy-duty trucks such as those used in commercial transportation contribute approximately 20% of the greenhouse gas emissions from transportation. Other means of commercial transportation such as airplanes, ships, and trains account for less than 20%. Fuel consumed in international travel by aircraft and marine sources is not counted in national greenhouse gas inventories, so the actual number is higher.

  • Aircraft can have some unique and complex effects on the atmosphere due to the release of emissions and water vapor at high altitude. Contrails affect the cloudiness of the earth's atmosphere, and therefore might affect atmospheric temperature and climate. http://climate.dot.gov/about/transportations-role/overview.html
