Carbon Intensity Explained
A carbon intensity (CI) score measures the lifecycle greenhouse gas emissions associated with producing one unit of energy from a fuel, expressed in grams of CO2 equivalent per megajoule (gCO2e/MJ).
In every major low-carbon fuel program - LCFS in California, CFR in Canada, ISCC in Europe - your CI score is the direct input to how many compliance credits you generate. A lower score means more credits. More credits means more revenue.
Most producers don't know their indicative CI score until they've already paid a consultant and started a formal certification application. That creates months of uncertainty. Our calculator solves that.
CI Score Components
Program Coverage
Whether you're an RNG producer pursuing LCFS credits, a biomethane operator certifying under ISCC, or an ethanol plant exploring your CI position, the calculator produces a scheme-specific score with a transparent breakdown.
01 · LCFS
CI scoring for RNG, renewable diesel, ethanol, and biodiesel pathways under CARB's CA-GREET model.
California · CARB02 · CFR
CI calculation aligned to the ECCC Fuel LCA Model (GHGenius) for Canadian RNG producers.
Canada · ECCC03 · ISCC
CI calculation with mass balance context under RED II/III for European biofuel and biomethane markets.
EU · ISCC06 · 45Z
CI scoring for ethanol, RNG, and SAF pathways under the IRS lifecycle model for federal tax credit qualification.
Coming soon07 · CFP and CFS
State-level LCFS-adjacent programs. Pacific Northwest operators can join the waitlist now.
COMING SOON08 · RTFO
CI scoring for biomethane and advanced fuel pathways under the DfT's carbon and sustainability reporting requirements.
COMING SOONHow It Works
No account required. No consultant fee. Upload your docs or enter key inputs manually and get a transparent, scheme-specific CI breakdown you can act on immediately.
01 · Upload
CSV, PDF, or filled-in templates. We parse the inputs we need to compute a directional score. Or enter key values manually.
02 · Score
Per scheme, with a transparent breakdown of feedstock, transport, process energy, and co-product credits. See what's driving your number.
03 · Act
Full report includes projected credit generation and revenue estimate. Leave an email to share with your team.
Default Mode
Built for operators who want a directional answer, fast.
Advanced Mode
For developers and compliance managers who need the full picture.
CI Score → Revenue
In LCFS, CFR, and other credit-generating schemes, every gCO2e/MJ improvement in CI translates directly to more credits per unit of fuel produced. At scale, a well-optimized CI pathway versus a default assumption can mean millions in annual credit revenue.

Frequently Asked Questions
The questions we hear most from producers, developers, and compliance teams exploring CI certification for the first time.
An indicative score is a directional estimate from your available production data and reasonable defaults. A certified score has been verified by an approved third party and registered with the relevant authority. Indicative scores guide investment decisions; certified scores are required to generate and sell compliance credits.
Accuracy depends on the quality of your inputs. With full production data, indicative scores typically fall within a few gCO2e/MJ of the certified result. With basic inputs, default assumptions widen the range. The calculator is transparent about which values are estimated vs. user-provided.
For a basic score: feedstock type, production pathway, annual production volume, and primary process energy sources. For a refined score: transport distances, energy mix detail, and co-product allocation. You can upload a process document and the calculator will extract relevant values automatically.
Uploaded documents are used only to extract CI-relevant inputs and are discarded after extraction. The tool is fully anonymous until you choose to download your report, at which point we ask for an email to deliver the file.
Yes. For most fuel types and pathways, the calculator produces a side-by-side CI score and projected credit revenue across all applicable schemes simultaneously - useful for biomethane producers deciding between LCFS, CFR, or both.
Once you have an indicative CI and revenue estimate, the next step is a formal certification application with an approved verifier. Mangrove's platform handles the ongoing data management, audit preparation, and credit reporting that certification programs require.
