Previous Life Cycle Analysis Models

CA-GREET3.0 Model and Tier 1 Simplified Carbon Intensity Calculators

The amendments to the LCFS regulation the Board adopted at its September 2018 hearing replace CA-GREET2.0 with the CA-GREET3.0 model and Tier 1 Simplified CI Calculators for LCFS fuel life cycle analysis. The CA-GREET3.0 model is used to generate the carbon intensities (CIs) of all fuel pathways, including Lookup Table pathways and applicant-specific Tier 1 and Tier 2 pathways.

Effective January 4, 2019 (released August 13, 2018*)

*Minor changes to models posted on August 13, 2018 are documented in the second LCFS errata.

CA-GREET3.0 Supplemental Document and Tables of Changes. The CA-GREET3.0 model was developed from GREET1 2016 developed at Argonne National Laboratory. Argonne’s currently supported GREET versions are available. The changes staff made in converting GREET1 2016 into CA-GREET3.0 are documented in this document.

Lookup Table Pathways (Table 7-1)

CA-GREET3.0 Lookup Table Technical Support Documentation. Describes the calculations, assumptions, and conditions for using the Lookup Table pathways developed by CARB using CA-GREET3.0. The CI of Lookup Table pathways for California Average Grid Electricity used in Transportation and the Smart Charging/Smart Electrolysis pathways are subject to annual updates, pursuant to section 95488.5(d). For the 2019 CIs of these electricity pathways, visit LCFS Pathway Certified Carbon Intensities and technical documentation.
