California Air Resources Board to consider re-adoption of LCFS in July

In California, at its July 2015 hearing, the California Air Resources Board will consider the re-adoption of the California Low Carbon Fuel Standard (LCFS).  Among the staff proposals the Board will be considering is the adoption of an updated version of the California-modified Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation (CA-GREET) model.  LCFS fuel pathways are grouped into either Tier 1 or Tier 2 under the proposed LCFS regulation.  The fuels that fall into these two tiers are described below.  Slightly different versions of the model are used to calculate Tier 1 and 2 CIs.  The Tier 1 version is called CA-GREET2.0-T1, while the Tier 2 version is called CA-GREET2.0-T2.   Since these versions contain the same data tables (they differ only in how CIs are calculated), they are collectively referred to as “CA-GREET 2.0.”
