Measure the project’s net greenhouse-gas balance over a defined boundary and reporting period—not just the tonnes of CO2 it captures. Count what is captured and delivered to storage, subtract attributable emissions and losses, and compare the result with a documented baseline using a stated accounting method. Captured tonnes alone do not prove that emissions fell.
First decide what claim you are measuring
“Reducing emissions” can describe several different claims. State which one the result supports, because the accounting question and tests may differ:
As an Amazon Associate I earn from qualifying purchases.
- Physical net emissions reduction: whether emissions within the defined project boundary are lower than in a stated baseline over a reporting period.
- Atmospheric removal: whether carbon dioxide was taken from the atmosphere and durably stored. Capturing fossil CO2 from a source before it is emitted is not, by itself, atmospheric removal.
- Offset credit: whether a program allows a quantified benefit to be issued as credits. In addition to measurement, programs can require eligibility, additionality, verification, and permanence tests.
A project can have a positive engineering net balance yet fail a particular crediting program’s requirements. Conversely, a crediting result should not be taken as proof of a broader claim if its boundary or baseline does not cover the emissions a reader cares about.

Draw the boundary around the parts of the project that the chosen protocol requires, and say where it begins and ends. Follow the CO2 and the inputs needed to capture and store it. Depending on the project and method, relevant stages can include the capture source and facility, conditioning, energy and material inputs, transport, injection, storage, construction, operation, completion, and post-closure monitoring.

Choose a reporting period and identify whether the accounting also covers later leakage or reversal. A result for one operating year is not automatically a lifetime result. ISO/TR 27915:2017 describes lifecycle quantification and verification issues across the CCS chain, including project assessment through post-closure; confirm its current status and any regulatory or contractual requirements that apply. The European Union’s Delegated Regulation 2026/285 contains provisions for carbon-removal quantification, including capture-facility and input emissions, losses, and mass balance; apply it only when the activity and legal framework fall within its scope.
Track captured CO2 through to storage
Measure mass at the points required by the applicable method, using its specified instruments, stream-composition and flow procedures, calibration, sampling, and records. Keep the quantities distinct: CO2 captured is not necessarily the same amount as CO2 transferred, injected, or retained in storage.
| Quantity | What it tells you | Records to reconcile |
|---|---|---|
| Captured | Mass removed from the source stream at the capture point | Required flow and composition measurements, sampling, calibration, and operating records |
| Transferred | Mass handed from the capture operation to transport or another project component | Transfer records and any measured losses or vents between capture and handoff |
| Injected | Mass delivered into the storage site | Transport and injection records, including losses before injection |
| Stored and monitored | Mass accounted for under the method’s storage and permanence rules | Storage-site monitoring, reported leakage or reversals, and records for the required monitoring period |
Australia’s Measurement Determination specifies measurement of the captured greenhouse-gas stream at the point of capture and sets sampling and gas-analysis requirements; its methods are jurisdiction-specific. Reconcile capture measurements with downstream transport and injection records rather than treating the capture-meter total as the stored total.

Inventory project emissions and losses
Quantify emissions attributable to the project within the chosen boundary. Depending on the applicable method, the inventory can include:
- Fuel and electricity used by the capture plant, including the emissions associated with producing that energy.
- Emissions from relevant materials and process inputs, as well as conditioning, transport, injection, and storage operations.
- Other material greenhouse gases covered by the method.
- Intentional vents, accidental fugitive emissions, transport losses, and other losses before permanent storage.
- Storage-site leakage, above-ground fugitive emissions, or later reversals where the protocol requires them.
Do not assume that a project powered by low-emissions electricity has zero energy-related emissions, or that a loss is immaterial because it is small relative to capture. Use the measurement and calculation rules of the chosen method and disclose material exclusions. The EU’s 2026/285 provisions explicitly address capture-facility emissions, input emissions, and certain pre-storage losses; those provisions do not establish a universal accounting rule for every project.
Calculate the net result against a baseline
A useful conceptual calculation is:
Net project reduction for a reporting period = baseline emissions avoided or removed under the chosen method − project emissions within the boundary − transport and storage losses or reversals included by that method.

This is a guide to the accounting logic, not a universal crediting equation. Apply the selected protocol’s equations, gas-conversion factors, monitoring periods, and eligibility rules. State the baseline clearly: it represents what would have happened without the project under the chosen accounting method. For crediting, assess additionality separately using the program’s criteria; measuring a physical net balance does not itself establish additionality.
Report the origin of the CO2—for example, fossil, biogenic, or atmospheric—so readers can tell whether the claim concerns avoided emissions or atmospheric removal. These are different claims and need the source and accounting treatment to be clear.
Monitor leakage and permanence for the required period
Storage performance is part of the result, not a separate detail. Track injection and the monitoring required for the storage site, report leakage or reversals, and apply the method’s post-injection or post-crediting requirements. Some schemes require monitoring after crediting ends.

The California Air Resources Board’s CCS accounting and permanence protocol is identified as a draft; it describes accounting for operating emissions, surface leakage, above-ground fugitive emissions, and post-well-closure emissions. Check its status and applicability before treating it as a binding current requirement. Australia’s ACCU CCS method page, last updated 4 August 2026, describes crediting for capture and permanent underground geological storage, with an extended accounting period to monitor possible leakage after the crediting period. That is Australian scheme guidance, not a global rule.

What a project comparison must include
Do not rank projects by captured tonnes alone. For a meaningful comparison, use a common protocol or explain the methodological differences, and align the reporting periods and boundaries. Compare the following:
- Net tonnes of CO2e and the stated period and boundary.
- Capture source and whether the CO2 is fossil, biogenic, or atmospheric in origin.
- Energy source and emissions intensity, plus relevant material and process-input emissions.
- Captured, transferred, injected, and stored quantities; transport losses and fugitive emissions.
- Storage permanence plan, leakage and reversal monitoring, and the period covered.
- Baseline and additionality treatment, crediting program, verification status, and uncertainty.
Without matched project data and a consistent method, a numerical league table would not establish which project delivers the greater net benefit.
