Yellowstone National Park, Wyoming:  Biodiesel powers about 300 vehicles, boilers and other diesel equipment at the world’s first and most famous National Park – Yellowstone.    The park manages to gracefully handle 2.5 million annual visitors.  One thing that helps protect the park from pollution is the use of B20. 

Jim Evanoff, the Environmental Manager for Yellowstone, has been a leader in biodiesel use and education for more than a decade.  It was in 1996 that he began using biodiesel in one of the park's vehicles (which he still drives), and now Yellowstone's entire diesel fleet operates on biodiesel.

“Our diesel vehicles run great on B20 all year,” Evanoff said.  “Even during our coldest days, the vehicles have started fine.”

In 2006, the biodiesel industry recognized his commitment.  At the National Biodiesel Conference & Expo in San Diego, the National Biodiesel Board (NBB) and actress Daryl Hannah presented Evanoff with the “Inspiration Award.”

“As stewards of the country’s first national park, it is our duty and responsibility to preserve and protect this national treasure,” Evanoff said.  “By using this biodegradable, renewable fuel in the park’s sensitive environment, we are practicing a high level of sustainability that other national parks around the country have followed.”

The park is also home to biodiesel and ethanol pumps that make biofuels available to the public.
