Report
A carbon number you can trace back to a meter.
Carbon Ledger turns the energy you already measure into emissions, month by month. Grid electricity, open-access power, rooftop solar, diesel generators, boilers and furnace fuel each get a line with the activity data, the emission factor, its source and the result. Nothing is a black box.

What Carbon Ledger does on a working day.
Scope 2 from meters
Grid electricity emissions from actual metered consumption, using location-based and market-based methods side by side.
Scope 1 fuels
Diesel for DG sets, LPG, natural gas, furnace oil and coal from fuel logs, flow meters or purchase records.
Renewables credited
Rooftop solar and green open-access power are separated out so their effect on market-based emissions is explicit.
Traceable factors
Each factor shows its source and year. When a new national factor is published, prior months stay locked unless you choose to restate.
Intensity metrics
tCO2e per unit produced, per square foot or per occupied room, ready for comparison and disclosure.
Site roll-up
Per site, per business unit and company-wide totals, with a clear boundary of what is included.
How it goes live at your site.
- 1
Define boundary
Choose sites, sources and the reporting year. Set your base year.
- 2
Connect activity
Meters feed electricity automatically. Add fuel logs or connect flow meters.
- 3
Apply factors
Default factors are pre-loaded per country. Override with supplier-specific values where you have them.
- 4
Close the month
Lock each month once reviewed. The ledger becomes the source for ESG reports.
About Carbon Ledger
Carbon Ledger focuses on Scope 1 and Scope 2, where your meters give accurate activity data. Scope 3 figures from other systems can be imported for completeness in the report.
National grid factors for Scope 2 location-based, IPCC default factors for fuels, and supplier-specific or certificate-backed values for market-based where you provide them.
Yes. Give them read-only access and they can drill from any total down to the meter series or bill behind it.
Closed months are locked. A restatement creates a new version with the reason recorded, and both versions remain visible.
