For fleets using propane autogas, cleaner operation is more than a superficial feel-good benefit. As a new report proves, the emissions reductions of propane autogas are significant for a variety of fleet types. These fleets are making a measurable impact on their communities by cutting harmful emissions.


From August 2016 through January 2017, the Propane Education & Research Council contracted the Gas Technology Institute (GTI) to execute a comparative emissions analysis study of targeted applications in key propane markets, including on road transportation. The report studied three emissions types: full-fuel-cycle energy consumption, greenhouse gas emissions, and criteria pollutant emissions (NOx, SOx).


Now propane marketers can enjoy the same emissions benefits they deliver to their customers. Propane bobtails not only cut emissions — their mileage and performance meet marketers’ needs.

  • NOx: 4% less vs. diesel
  • GHG: 12% less vs. diesel


Conventionally fueled buses put students face to face with a black cloud of smoke every school day. With propane autogas buses, districts can significantly clean up the air around students and their neighborhoods.

  • NOx: 96% less vs. clean diesel buses


With every mile driven, businesses and municipalities with fleet vehicles make an impact on emissions. They rely on propane autogas vehicles for powerful performance combined with real emissions reduction.

  • SOx: 37% less vs. gasoline
  • NOx: 36% less vs. diesel • 5% less vs. gasoline
  • GHG: 12% less vs. gasoline
