The scope of this series and its recommendations is limited to the US transportation industry for a few reasons. Historical price and consumption data for petroleum products is readily available from the Energy Information Administration, so the size of the market is well known. Many aspects of the industry are regulated and enforced, such as emissions standards, and sales infrastructure. Because of the regulation, recommendations incorporated into legislation have greater potential for implementation, like the required B2 blend in Minnesota, as well as the Ultra Low Sulfur Diesel (ULSD) national requirements mandated and enforced by the EPA.
Switching from petrodiesel to biodiesel in the US can also have a large impact because the market is one of the largest in the world7, and the transportation industry consumption accounts for 18% of total refined petroleum products and 82% of petroleum distillate in the United States. (EIA)
