The staff of the California Air Resources Board (ARB) has released an update to the California-GREET model 1.8b for estimating the carbon intensities of transportation fuels as part of the Low Carbon Fuels Standard (LCFS) rulemaking process.
This update reflects updates in the September 2008 release of the Argonne National GREET model. Additional information to include criteria pollutants is also updated in the model. The model does not include the land use change estimate.
For this release, updates have been performed for CARBOB, ULSD, CaRFG, CNG, and Electricity. Pathway documents reflecting the updates will be posted to the ARB website shown below over the next 1-2 weeks. An additional update to incorporate the other fuel pathways will also be posted in the next 1-2 weeks.
The modifications were made by Life Cycle Associates, LLC.
