Exact by design
The engine uses exact-decimal maths, so thousands of activity lines add up without drift. There is no rounding error for an auditor to catch.
Carbon accounting
Carbon accounting software built for Nigeria
Measure your Scope 1, 2, and 3 emissions on an audit-proof ledger, using Nigerian grid and generator data. Every figure is traceable, reproducible, and ready for assurance. Greenhouse gas accounting that reflects how your business actually runs. Priced in Naira.
Scope 1, 2, and 3. Emissions tracking you can defend.

You logged hours. Emvert converted hours to fuel to emissions, assigned the scope, and kept the assumption on the record.
Assurance
Not a carbon number. A number you can prove.
Most tools give you a figure. Emvert gives you a figure you can trace, reproduce, and defend. That is what audit-ready carbon accounting means.
Immutable emissions ledger
Every figure links to the exact emission factor version and formula used, with a timestamp. The ledger is append-only, so a correction is a reversing entry, never an edit.
Reproducible emissions calculation
Re-run any past period and Emvert returns the same figure, using the factors that were valid at the time.
Every activity gets its scope automatically
You never pick a scope. Emvert reads the asset and the activity, then assigns Scope 1, 2, or 3 for you. Automatic scope classification removes the most common source of error in a carbon inventory, and keeps your numbers consistent across sites and years.
Built on Nigerian data
Factors that match how Nigeria runs
Diesel generator emissions, for how Nigeria runs
Generators are the largest emitter for most Nigerian companies. Where you record only run hours, Emvert converts hours to fuel to emissions and stores the assumption it used. Diesel generator emissions calculation built for Nigeria, not bolted on.
diesel generator emissions calculator →Scope 2 on the NERC grid, two numbers
For purchased electricity, Emvert uses the NERC grid emission factor and Disco factors by region, so grid emissions count for where you actually draw power. You get both figures the standards ask for, location-based and market-based, side by side.
Scope 2 electricity calculator →One clean CO₂e figure
Carbon dioxide, methane, and nitrous oxide are converted to a single comparable number using the chosen warming-potential basis, so multi-gas activity rolls up correctly.
Refrigerants and industrial gases
Fugitive emissions are calculated by leak rate and recharge mass, not a fuel factor, so cooling and process gases are counted properly.
Keep the factor, method, and evidence with the number
The factor library is versioned and connected to the calculation trace. When a factor changes, the ledger preserves what was used before, so historical figures remain reproducible.
Nigeria emission factors →Data entry
Carbon accounting from data you already have
Five ways in, one clean ledger.
Asset-based entry
Add locations, vehicles, and equipment once, then log what each consumed with the source attached.
Spend-based emissions from accounting data
Tag transactions from your accounting system to emission categories by GL account.
Read from invoices
Upload a bill and Emvert uses invoice OCR for carbon data, suggests the factor, and logs the machine action. You confirm.
Bulk import
Upload a spreadsheet. See accepted and rejected rows with a reason. Nothing enters until you confirm.
Suppliers and connectors
Invite suppliers to submit Scope 3 data, and connect finance, utility, and fleet systems.
Analytics
Emissions tracking you can act on, and defend
Trends over time, breakdowns by scope, site, and source, and intensity figures against revenue and headcount. From any total, drill straight down to the single activity behind it. Built as emissions tracking software for Nigerian teams, the ledger keeps the calculation method attached to the result.
- Track Scope 1, Scope 2, and Scope 3 across periods.
- Compare sites, sources, and operational intensity.
- Open the activity and evidence behind any total.
- Keep the method attached as the inventory evolves.

Why Emvert
Live numbers, with the method attached
A carbon inventory should not disappear into a spreadsheet or a PDF after the annual exercise. Emvert keeps the number and the method together.
Versus a consultant
A live number, not a yearly handover
A consultant hands you a figure in a PDF once a year. Emvert gives you a live number with the evidence and the method attached.
Versus a spreadsheet
Assumptions that do not disappear
A spreadsheet drifts, breaks, and hides its assumptions. The immutable ledger records every one.
Versus a global tool
Built around Nigerian operations
Global tools apply US and EU averages. Emvert applies the NERC grid factor and Nigerian generator data.
FAQ
Carbon accounting in Nigeria, answered
What is carbon accounting?
Carbon accounting is measuring the greenhouse gases your company produces, grouped into Scope 1, Scope 2, and Scope 3. Emvert calculates this on Nigerian data and records every figure on an audit-proof ledger, so the numbers hold up to assurance.
How do I calculate Scope 2 emissions in Nigeria?
Multiply the electricity you buy by the grid emission factor for your location. Emvert does this with the NERC grid factor and Disco factors by region, and gives you both the location-based and the market-based figure the standards require.
How do I calculate diesel generator emissions?
Convert fuel used into emissions with a diesel emission factor. Where you record only generator run hours, Emvert converts hours to fuel to emissions using Nigerian generator data, and stores the assumption it used so the figure is auditable.
How do I measure my company carbon footprint in Nigeria?
List your emission sources, then apply the right factor to each. In Emvert you add your locations, vehicles, and equipment, log or import their activity, and the engine calculates Scope 1, Scope 2, and Scope 3 for you, using Nigerian factors.
What is the difference between Scope 1, 2, and 3?
Scope 1 is direct emissions you produce, like fuel and generators. Scope 2 is the electricity you buy. Scope 3 is your value chain, like suppliers, travel, and waste. Emvert assigns the scope to each activity automatically.
What makes the numbers audit-ready?
Every figure sits on an append-only ledger, linked to the exact factor version and formula used, with the evidence attached. Any past period recomputes to the same number, which is what an assurer looks for.
Does Emvert assign the scope for me?
Yes. You never choose a scope. The engine assigns Scope 1, Scope 2, or Scope 3 from the asset and activity, so there is no misclassification.
Does the AI decide my emissions?
No. The assistant reads documents and suggests values, but a person confirms every figure, and the deterministic engine does the actual calculation. Every machine action is logged.
