Source: U.S. Energy Information Administration, Petroleum Supply Monthly , Monthly Energy Review Note: Distillate fuel volumes with sulfur content below 15 parts per million produced before 2004 are included in the 'between 15 and 500 ppm' category. Distillate fuel supply for 2014 includes estimated volumes for December 2014 from the Short-Term Energy Outlook, February 2015. Republished February 24, 2015, 9:30 a.m. to correct an error. Distillate fuel oil supply consists primarily of diesel fuel used for transportation and of heating oil burned in furnaces and boilers. Over the past 20 years, the U.S. Environmental Protection Agency (EPA) has regulated the amount of sulfur contained in diesel fuel to enable reductions in harmful emissions of nitrogen oxides and particulate matter from diesel engines . Since 2006, most distillate fuel has had less than 15 parts per million (ppm) of sulfur, a drastic change from the early 1990s, when high-sulfur...
