Global Registry for Verified Fuel Attributes
The Digital Fuels Registry™ provides a system for issuing, tracking, transferring and retiring standardized environmental attributes of low-carbon fuels. It enables participants to document lifecycle emissions at the batch level – creating transparency and comparability for producers, distributors and corporate buyers.

Batch-Level Attributes
Tracks carbon intensity at the batch level based on lifecycle emissions across feedstock, production, transportation, distribution and use
Standardized Emissions Data
Provides consistent measurement and reporting aligned with international frameworks
Trusted Market Infrastructure
Built on the same registry technology trusted by global renewable energy and carbon markets
End-to-End Traceability
Multi-step verification ensures accurate measurement and no double counting with regulated markets
The Voluntary Registry for Transport Emission Reductions
How It Works
The process is straightforward, efficient and trusted by leading producers and corporate sustainability teams.
Register Fuel Supply
Biofuel producers register fuel sources under approved carbon-intensity methodologies.
Issue TERCs
- A Transport Emission Reduction Certificate (TERC) is a tradable credit representing the lifecycle emission reductions of low-carbon fuels.
- One TERC represents one metric ton of CO2-equivalent emissions reduced.
- TERCs enable buyers to achieve corporate sustainability goals while supporting the deployment of low-carbon fuels in the U.S. The program incentivizes alternative, non-fossil fuel producers to lower the carbon intensity of their product and provide credible claims of carbon avoidance to buyers.
- Each batch is tied to verified supply quantities.
Transfer Certificates
Attributes can be securely transferred to buyers, enabling low-carbon procurement strategies..
Retire for Claims
Purchasers retire TERCs to support emissions reduction claims and sustainability reporting.

Frequently Asked Questions
Answers to common questions about Digital Fuels Registry
What is the Digital Fuels Registry?
The Digital Fuels Registry is a secure, auditable system for issuing, tracking, transferring and retiring emission reduction attributes of low-carbon fuels. It prevents double counting through multi-step verification of environmental attributes, providing a high-integrity solution for voluntary sustainability claims.
What is a Transport Emission Reduction Certificate (TERC)?
A Transport Emission Reduction Certificate is a tradable credit representing the lifecycle emission reductions of low-carbon fuels. One TERC represents one metric ton of CO2-equivalent emissions reduced.
What is the TERC program?
The TERC program – a joint initiative of Eco-Energy, Xpansiv and other organizations – is a voluntary, market-based initiative aimed at reducing greenhouse gas emissions from transportation, focused on low-carbon fuel production and use across the United States.
Inspired by the success of regulated low-carbon fuel standards, which are designed to reduce greenhouse gas emissions in the future below a certain level, the TERC program enlists the voluntary participation of fuel producers and fuel consumers to drive down the carbon intensity of transportation fuels.
What makes the TERC program unique?
State and national mandated LCFS programs are proven effective at lowering fuel pool emissions, diversifying supply and promoting investment in technology, but only obligated parties are required to participate. The TERC program allows low-carbon, renewable fuel producers to voluntarily create standardized and transparent certificates verifying greenhouse gas (GHG) benefits compared to petroleum alternatives. TERC buyers gain the ability to claim reductions and mitigate the environmental impact from the fuels they use regularly.
What are the benefits of using a TERC?
Revenue from the sale of TERCs goes back to low-carbon fuel producers to incentivize carbon-reducing innovation, expanding the benefits of a regulated LCFS credit into the voluntary space – expanding decarbonization of the fuel pool, avoiding emissions from transportation and logistics applications and validating sustainability commitments of the companies who acquire them.
Buyers with large scope 3 emission footprints are investing back into their own value chain by promoting the reduction of carbon intensity of the fuels that currently power their businesses.
How is TERC different from a regulated LCFS program?
Only obligated parties can participate in regulated LCFS markets. As part of the TERC program, biofuel producers with product that doesn’t go to a regulated market can voluntarily choose to undergo the scrutiny of an annual carbon intensity verification conducted by an independent third-party engineering and accounting firm. Producers with fuel that falls under the mandated baseline for program participation generate TERCs consistent with the carbon intensity of their fuel.
Voluntary buyers can acquire TERCs to claim emission mitigation.
How can companies use TERCs to meet their sustainability goals?
Companies with emission reduction goals often invest in improving energy efficiency, adopting renewable energy sources, optimizing logistics and implementing sustainable practices in operations. However, the transportation sector faces particularly challenging and capital-intensive hurdles to abatement. Companies with large scope 3 emissions can claim their sustainable energy choice with the purchase of TERCs and reduce the environmental impact from the fuels they use regularly. The certificates are issued, tracked and retired via the Digital Fuels Registry.
Transparent communication to stakeholders about carbon reduction efforts are essential through sustainability reports, corporate social responsibility initiatives and public statements.
