Introduction
The California Air Resources Boardโs (CARB) Low Carbon Fuel Standard (LCFS)
regulation (regulation), which appears at sections 95480 to 95503 of title 17, California
Code of Regulations, is designed to reduce greenhouse gas emissions associated with
the life cycle of transportation fuels used in California. CARB staff has prepared this
document to provide further detail on the calculation methodology. Unlike the
regulation itself, this document does not have the force of law. This document is not
intended to, and cannot, establish requirements beyond those that are already in the
regulation, nor can it supplant, replace, or amend any of the legal requirements of the
regulation. Conversely, any omission or truncation of regulatory requirements as
recited in this discussion does not relieve entities of their legal obligation to fully
comply with all requirements of the regulation.
Methodology
An Electrical Distribution Utility (EDU) can generate credits for electricity supplied to
the electric forklift fleet in its service territory during a reporting period if not claimed
by another eligible entity.1 CARB calculates the amount of electricity used to charge
electric forklifts in an EDUโs service territory that has opted-in to the LCFS on a
quarterly basis. The quantity of unclaimed electricity supplied to forklift fleets in an
EDUโs territory is the difference between the estimated total electric forklift fleet
usage within a service territory and the quantity of electricity reported for forklift fleet
fueling in the same service territory for a given reporting period.
CARB determines the quantity of electricity supplied to forklift fleets within a given
EDU service territory to determine the quantity of electricity allocated under section
95483(c)(4)(B) paragraph 3: ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น =๏ฟฝ๐๐๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น× ๐ธ๐ธ๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น× ๐๐๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๏ฟฝโโ๐ธ๐ธ๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐ ๐ ๐ ๐ ๐น๐น Equation 1

Where: ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น is the total electricity (kWh) for forklifts estimated for an individual EDU for
a given quarter; ๐๐๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น is the number of electric forklifts operating in California, as estimated from
the SSRC CARB LSI study;2 ๐ธ๐ธ๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น๐น is the quarterly average electricity use (kWh/forklift-quarter) of a typical
electric forklift, as estimated by Electric Power Research Institute (EPRI);3 ๐๐๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ is a dimensionless value representing the relative fraction of the forklift fleet
attributable to an EDU approximated from non-residential (commercial and
industrial) electricity consumption provided by California Energy Commissionโs
"Electric Consumption By Utility Dataset;โ4 and โEiForkliftRPi is the sum of all reported electricity for electric forklifts (kWh) claimed
by reporting entities in each EDU territory for a given quarter.
CARB calculates and issues the credits claimed by EDUs on a quarterly basis after
close of the quarterly reporting deadline.5 The LCFS provides for two types of forklift
vehicle fuel applications differentiated by model year as described in Table 5 of the
regulation; post-2010 and pre-2011.6 Starting for the Q2 2021 reporting period,
CARB will use the previous four quarters data to calculate the average forklift vehicle
application as reported per 95491(d)(3)(E) paragraphs 1-2 and applies that average
forklift application to the EDU forklift credits. For example, Q2 2021 EDU forklift
credits will use an average proportion between the two forklift applications from Q2
2020 through Q1 2021 reported data.
2 SSRC CARB LSI study https://ww2.arb.ca.gov/sites/default/files/2020-08/ssrc_2017.pdf. CARB staff
estimates the size of the total electric forklift fleet from Table 75 (page 118). Through 2020, CARB staff
utilized the โPopulation lower boundโ estimate for estimating forklift population. Starting from Q1
2021, CARB utilizes the โPopulation upper boundโ estimate. This value was changed to better reflect
the total forklift electricity load as reported electricity in the LCFS exceeded the previous estimate.
3 EPRI forklift usage report
https://ww2.arb.ca.gov/sites/default/files/classic//fuels/lcfs/electricity/epri_2015.pdf. CARB staff uses
the low estimate for electricity usage per forklift.
4 CEC Electric Consumption By Utility Dataset http://www.ecdms.energy.ca.gov/elecbyutil.aspx. CARB
staff uses โCommercial Buildingโ, โCommercial Otherโ, and โIndustryโ categories for the estimation.
5 Per section 95491(d)(3)(E) paragraph 3. credits issued to EDUs for unclaimed electricity supplied for
forklift fueling are exempt from quarterly reporting deadlines set forth in section 95491(b).
6 The credit calculation and Table 5 can be found in section 95486.1(a) of the regulation. Prior to Q2
2021, CARB estimated the population for EDU forklifts credits to be pre-2011.
