"Oregon" calculations include credits potentially available from Oregon’s Clean Fuels Program. "Other States" calculations assume no low carbon fuel program.

Selection of Oregon vs. Other states:

Oregon-based fleets should select “Oregon.” By doing so, your fleet will share in revenue from sale of Oregon Clean Fuels Program (CFP) credits. Selecting “Oregon” also means that Greenhouse Gas (GHG) reductions will be measured against the blended Carbon Index Score of 90.48 gCO2e per MJ associated with Oregon’s 2020 – 2035 Clean Fuels Program. When a fleet selects “Other State”, your proposed fleet-conversion project will not share in revenue from sale of CFP credits, and your fleet’s anticipated GHG reductions will be measured against fossil Diesel’s Carbon Index Score of 101.1 gCO2e per MJ. Oregon’s Clean Fuels Program is closely based on California’s Low Carbon Fuel Standard (LCFS). As such, California-based fleets that use this tool may wish to select “Oregon” to ensure that they share in revenue from sale of LCFS credits. When doing so, California-based fleets should recognize both that the value of LCFS credits is significantly greater than the per Metric Tonne value of Oregon CFP credits, and that the blended CI Score for California’s transportation fuel mix will differ from the CI Score for Oregon’s transportation fuel mix.

Accuracy Disclaimer:

This online calculator is intended to help fleets quantify financial and environmental outcomes associated with a proposed conversion from Diesel to Conventional or Renewable Natural Gas (CNG/RNG). As such, this tool should be used for estimation purposes, only. If preliminary results obtained through use of this tool seem promising, we strongly encourage fleet managers to conduct a thorough fleet-conversion assessment. Most fleets that operate in Oregon, Washington State, or Idaho may secure assistance preparing detailed fleet-conversion analysis from the NW Alliance, free of charge.

Results

This section quantifies the number of years it will take the fleet to recover the incremental vehicle, fueling-, and maintenance-infrastructure costs associated with converting from Diesel to CNG/RNG or battery-electric fuel technology. It also estimates potential financial savings or losses and GHG reductions associated with the conversion from Diesel to the listed alternative fuels. Again, these are estimates, only, and we strongly encourage preparation of a fleet-specific analysis prior to committing to a fuel switch from Diesel to alternative fuels.

When vehicles use a biomass-based renewable fuel, like Renewable Natural Gas (RNG), they earn Renewable Identification Numbers (RINs) under the EPA’s Renewable Fuel Standard program. 11.727 RINs are earned per million British thermal units (per MMBtu).

When fleets use low carbon fuels in states that have a Low Carbon Fuel Standard, as is the case in Oregon, they earn Clean Fuels Program credits (CFP credits). Each CFP credit represents one Metric Tonne (MT) of Greenhouse Gas (GHG) reductions, and the marketplace assigns a value to these CFP credits.
