The Fuel Alternatives and Options guide, provided by the Indiana Department of Environmental Management (IDEM) through its DieselWise Indiana program, is a strategic resource for mayors looking to modernize municipal fleets and reduce the “diesel signature” in their cities.

Specifically, this webpage serves as a technical guide for city planners and fleet managers. It outlines the primary substitutes for traditional petroleum diesel, including Biodiesel, Compressed Natural Gas (CNG), Liquefied Natural Gas (LNG), Propane (LPG), Electricity, and Hydrogen. For each fuel type, the resource provides a breakdown of its chemical properties, compatibility with existing engines, environmental benefits, and the infrastructure required to support its adoption.
