Frequently Asked Questions
Equipment Users
I want to purchase CORE-eligible equipment. How do I apply for a voucher?
In order to access CORE funding/eligible equipment, you must work through an approved CORE dealer who will submit a voucher request on your behalf. CORE-approved dealers secure CORE voucher funding through the online Voucher Processing Center, and the incentive is applied at the point of sale. If you have a preferred dealer or equipment in mind, connect us with your dealer, and we can help them become CORE-approved.
Does the size of the fleet matter? No, fleet size does not matter. Requirements and eligibility do not differ based on the size of the fleet.
Can I apply for more than one voucher? Yes.
Do I need to be in compliance with regulations prior to applying for a voucher request?
Purchasers are required to be in full regulatory compliance prior to submitting a voucher request application. If the Project Administrator requests documentation to verify compliance or a valid exemption, and the purchaser fails to provide such documentation within 30 calendar days, the voucher request may be subject to cancellation. Purchasers may submit a new voucher request for CORE funding once compliance is verified.
DOORS: Off-Road Diesel (ORD) Regulation
All eligible equipment types except TRUs and CHC
TRUCRS: Truck Regulation Upload, Compliance and Reporting System
TRUs only
ARBER: Air Resources Board Equipment Registration
TRUs only
CHC: Commercial Harbor Craft Regulation
CHC only
How long does a purchaser need to have been operating in California to qualify for a CORE voucher?
The purchaser must show proof of business operations in the State of California for a minimum of one year prior to voucher request. This must include proof of valid registration with the Secretary of State for the business entity (CARB or its designee may utilize the California Secretary of State Business Search portal to determine validity of business entity registration) or provide a valid business license issued by the municipality in which the purchaser operates.
Program Basics
What is the Clean Off-Road Equipment Voucher Incentive Project (CORE)? The CORE Project was established to reduce price barriers, enabling users to adopt more zero-emission equipment. Created by the California Air Resources Board (CARB) in 2017, CORE provides point-of-sale discount vouchers that reduce the purchase cost of equipment operated in California. CORE Project vouchers make zero-emission equipment as affordable as their traditional fossil-fueled counterparts at the point of sale. Funded equipment includes off-road equipment used at ports, rail yards, distribution centers, freight facilities, construction sites, and agricultural industries. CARB recognizes that this equipment has the proven ability to reduce criteria and greenhouse gas pollutants in California and aims to accelerate the penetration of this cleaner equipment to help meet clean-air regulations and climate change goals. The CORE Project is part of the California Climate Investments, a statewide initiative that invests Cap and Trade dollars.
How can I be notified of CORE news and events? Sign up for the CORE Project listserv by completing the Contact Us form.
How do we know how much money is available? The funding ticker at the top of the home page represents funding availability. This reflects the real-time funding availability based on the vouchers requested.
How do I know what equipment is eligible for CORE? All CORE-eligible equipment can be found in the CORE Eligible Equipment Catalog.
What are the base voucher amounts? Base voucher amounts vary based on equipment and consider factors such as type, battery or hydrogen fueling, battery capacity, etc. Please see the base voucher amounts table above for information on voucher pricing.
Is stacking allowed with other funding, grants, incentives, etc.? While CORE does not prohibit combining its vouchers with other incentive programs, the total combined public funding (i.e., “stacking”) cannot exceed 100% of the base equipment cost—or, in the case of conversion kits, 100% of the cost of the kit plus installation (excluding taxes and fees).
How does funding prioritization work? Once the funding for a particular category has reached its cap, new voucher requests for that equipment type (including conversions of that equipment type) will be placed on a contingency list. However, there is no guarantee that funding will be available for the voucher requests on the contingency list.
What is considered a small business? “Small business” is defined in CORE as: [An] independently owned and operated business that is not dominant in its field of operation, the principal office of which is located in California, the officers of which are domiciled in California, and which, together with affiliates, averages annual gross receipts of fifteen million dollars ($15,000,000) or less over the previous three years.
Dealers and Manufacturers
I represent a dealership. How do I apply for a voucher? Each staff member at a dealership interested in participating in the CORE Project must individually complete the following steps outlined below:
- The dealership must sell CARB-approved equipment featured in the Eligible Equipment Catalog.
- Submit a CORE Dealer Registration Form.
- Be prepared to accept dealer terms and conditions.
- Provide a copy of your dealership’s signed W-9.
- Allow up to 30 days for your Dealer Registration Form to be reviewed. After review, you will be sent a link to the CORE Dealer Training Module. You must complete the training and receive a minimum score of 80% on the final weighted quiz.
- Voucher Processing Center credentials will be issued within 30 days of approved status.
- For additional assistance, contact a CORE Project Administrator at [email protected].
I am a previously approved dealer; do I need to re-enroll? No, previously approved dealers do not need to re-register. However, as of July 2026, all dealers must undergo mandatory training to ensure program compliance.
I’m having trouble accessing the Voucher Processing Center. What should I do? You should reach out to [email protected]. The Dealer Enrollment Team can help you restore access.
My co-worker is CORE-eligible. Can I use their Voucher Processing Center login? No. Each staff member at a dealership interested in participating in the CORE Project must individually complete dealer enrollment to receive a Voucher Processing Center login. Sharing login credentials is strictly prohibited.
Is equipment that is delivered/titled/paid for prior to a voucher request submittal eligible for funding? No.
Are demo equipment purchases eligible for funding? No. In situations where the purchaser holds an equity interest in the manufacturer (or vice versa); where the purchaser and manufacturer are owned, partially or wholly, by a third party; or where the purchaser and manufacturer share common corporate officials who are responsible for the overall direction of each entity, such purchases shall be considered purchases by the manufacturer, itself, for the purposes of CORE and are not eligible for CORE voucher funding.
How does equipment become CORE-eligible? The California Air Resources Board evaluates equipment eligibility. Learn more HERE.
