This chart shows increasing biofuel use as reported by Truck Carrier Partners using the performance-based SmartWay Truck Tool for all classes of trucks, over each of the past four years. From 2011 to 2014 overall, biodiesel consumption has increased by 93%, and ethanol by 69%.


The term “biofuels” refers to fuel that derives from a renewable biomass resource (i.e., derived from plants or from animal fats). “Biodiesel” is a biofuel produced for use in diesel engines and is typically blended at 5%-20%, but may be more, with the remainder being conventional diesel fuel. In the U.S., ethanol is typically blended with gasoline to create E85 fuel, consisting of 85% ethanol and 15% gasoline. Using renewable content in fuel has a number of advantages, including reduced lifecycle greenhouse gas generation, reduced particulate matter emissions due to lower sulfur content, and improved U.S. energy security.

To highlight the trend seen among Truck Carrier Partners in the SmartWay program, this graph shows the annual rate of change in biodiesel and ethanol consumption, rather than the change in the overall amount consumed. In this chart, the rate of increase is adjusted to the number of trucks operated by Truck Carrier Partners. Scaling the biofuel consumption to the number of trucks for each year reveals that consumption increases are not simply due to partnership growth, but rather that Partners are increasingly choosing to use biofuel.


Biofuels utilize biomass feedstocks that are renewable; that is, they derive from sources that will not “run out,” in contrast with fossil fuels, the supply of which is limited to whatever remains in known and undiscovered reserves. In the U.S., corn is commonly used for ethanol production, and soybeans and canola for biodiesel. Other sources of biofuels, including less carbon-intensive crops and vegetative or agricultural wastes, are increasingly a part of the biofuel picture.

This chart is not based upon SmartWay Partner data, but instead upon data from the entire U.S. transportation sector,* which includes data from earlier years than the current platform of the SmartWay Truck Tool. The overall trend toward increased use of biofuels in the transportation sector increases until the last two to three calendar years of data, which show some leveling off.

While information from a different set of sources, using different methods for collection and analysis, should only be compared with care, the subset of the national transportation sector comprised by SmartWay Truck Carrier Partners continued to show increased consumption of biofuels in the 2011-2014 reporting years (corresponding to the 2010 – 2013 calendar years, which overlap the last three years of the national data).
