GHG accounting,
multi-entity, every scope
Build a complete Scope 1, 2 and 3 inventory across every site and subsidiary, consolidated to group level, with DEFRA and IEA factors matched to your reporting year and an assurance-ready trail.
Instant digital delivery. No installation.
Annual licence
Renewable each year, so your emission factors stay current, with ongoing access to your previous reporting periods.
A complete inventory, built properly
Direct and energy emissions, in detail
Capture combustion, fugitive and refrigerant losses and process emissions for Scope 1, and electricity, heat and cooling for Scope 2, shown both location-based and market-based. Biogenic CO2 is recorded as a memo item, as the GHG Protocol requires.
- Combustion, fugitive and process emissions
- Location and market-based Scope 2
- DEFRA and IEA factors matched to your year
- Biogenic CO2 as a memo item
The full value chain, category by category
Work through Scope 3 across upstream and downstream categories, with the PCAF method for Category 15 financed emissions. Each category is built up step by step, with data quality flagged so you know how firm each number is.
- Upstream and downstream categories
- PCAF method for financed emissions
- Data quality flagged per category
- Intensity ratios across the inventory
Every site and subsidiary, rolled up to group
Set up each site or subsidiary as its own entity, then consolidate to a single group inventory. No more stitching spreadsheets together at year end, the group total builds from the entities underneath it.
- Unlimited entities, one group view
- Consolidated Scope 1, 2 and 3 totals
- Per-entity and group intensity ratios
- Consistent factors across every entity
Ready for review before the auditor arrives
Built-in pre-assurance checks flag gaps, outliers and weak data quality before you submit. Export a Basis of Preparation that sets out your method, boundary and factors, so your reviewer can follow every number.
- Pre-assurance checks for gaps and outliers
- Data quality scored throughout
- Basis of Preparation export
- A clear trail from activity data to result
Get data in fast, get results out clean
Bring activity data in with the CSV bulk import and a ready-made template, instead of re-keying. When you are done, export your working data as CSV and your Basis of Preparation, or print the inventory to PDF.
- CSV bulk import with a template
- CSV export of working data
- Basis of Preparation document
- Print the inventory to PDF

The problems we solve
Group reporting is a spreadsheet mess
Each site keeps its own file, and stitching them into one group total at year end is slow and error-prone.
Emission factors go out of date
DEFRA and grid factors change every year, so last year's spreadsheet quietly produces the wrong number.
Scope 3 is overwhelming
The value chain spans many categories, and most teams do not know where to begin or how to estimate.
Auditors push back on data quality
Without a clear method and quality flags, an assurance reviewer sends the numbers straight back.
Re-keying data wastes days
Copying figures from energy bills and supplier sheets by hand is slow and introduces mistakes.
Calculators are black boxes
Many tools hide the method, so you cannot show how a figure was reached.
Up and running in three steps
Purchase & open
Buy your licence, get instant access, and open it in your browser. Load the sample data to see a finished inventory first.
Enter or import
Add each entity, then type your activity data or bring it in with the CSV import, across Scope 1, 2 and 3.
Consolidate & export
Review the group inventory, run the pre-assurance checks, and export your data and Basis of Preparation.
Everything, in one licence
Frequently asked questions
What does it calculate?
A complete greenhouse gas inventory across Scope 1 (combustion, fugitive and process emissions), Scope 2 (location and market-based) and Scope 3 (upstream and downstream categories, with the PCAF method for financed emissions), aligned to the GHG Protocol.
Can it handle multiple sites or subsidiaries?
Yes, this is what it is built for. Set up each site or subsidiary as its own entity, then consolidate to a single group inventory, with totals and intensity ratios at both entity and group level.
Which emission factors are used?
DEFRA and IEA factors, matched to your reporting year, applied consistently across every entity. Every factor is shown and can be overridden with a supplier-specific value where you have one.
Can I import data instead of typing it?
Yes. Use the CSV bulk import with the ready-made template to bring in activity data, rather than re-keying it from bills and supplier sheets.
Is it assurance-ready?
It is built to support assurance: pre-assurance checks flag gaps and outliers, data quality is scored, and you can export a Basis of Preparation setting out your method, boundary and factors. The figures support your own review and assurance; they are not an assurance opinion in themselves.
How does this compare to a carbon platform or a consultant?
Carbon-accounting platforms are typically per-seat or per-tonne subscriptions, and a consultant footprint is a one-off engagement that repeats each year. EcoLedger is £2,400 for the reporting year, you own the process, and you can repeat it in-house.
Where is my data stored, and is it secure?
You choose. Your data can stay entirely on your own computer, in your browser, or you can sign in to sync it securely and use EcoLedger from any device. Sign-in is passwordless, a single-use code sent to your email, your data is only ever transferred over an encrypted connection, on enterprise-grade hosting, and everything is exportable at any time.
