All Laws and Incentives Sorted by Type
The tables below summarize the number of clean transportation laws, regulations, and funding opportunities in a particular jurisdiction. By selecting the tabs above the table, you can view summary information by technology/fuel, incentive, regulation, or user type.
| Jurisdiction |
Biodiesel
Biodiesel is produced from a range of vegetable oils and animal fats. Pure biodiesel (B100) or biodiesel blended with petroleum diesel can be used to fuel diesel vehicles.
|
Ethanol
Ethanol is made from various plant materials, such as corn. Ethanol is blended with gasoline to fuel vehicles (e.g., E85 is a blend of 85% ethanol and 15% gasoline).
|
Natural Gas
Natural gas is a mixture of hydrocarbons. Natural gas can be stored onboard a vehicle as a gas (compressed natural gas, CNG) or a liquid (liquefied natural gas, LNG).
|
Propane (LPG)
Liquefied petroleum gas (LPG), or propane, is a three-carbon alkane gas produced as a by-product of natural gas processing or crude oil refining.
|
Hydrogen Fuel Cells
Hydrogen can be used to power fuel cells that generate electricity to run a vehicle's motor.
|
EVs
Electric vehicles (EVs) use batteries or other energy storage devices to store electricity to power the vehicle's motor.
|
HEVs or PHEVs
Hybrid electric vehicles (HEVs) combine the internal combustion engine of a conventional vehicle with the battery and electric motor of an electric vehicle. Plug-in hybrid electric vehicles (PHEVs) are equipped with batteries that can be charged by plugging into an electrical outlet.
|
NEVs
Neighborhood electric vehicles (NEVs) are small electric vehicles typically limited to speeds of less and 35 miles per hour.
|
Aftermarket Conversions
Aftermarket conversions refer to original equipment manufacturer vehicles altered to operate on another fuel type, such as propane, natural gas, ethanol, or electricity.
|
Fuel Economy or Efficiency
Fuel economy or fuel efficiency is the distance a vehicle travels per unit of fuel used and is commonly measured in miles per gallon (mpg).
|
Idle Reduction
Idle reduction is a decrease in the time or frequency that an engine runs while the vehicle is at rest.
|
Other
Includes emerging fuel types and additional technologies.
