Getting the data in
Someone types bill figures into a sheet each month.
Reads a file you paste in. Next month, you paste again.
Reads electricity bills, fuel invoices and Tally exports from your mailbox, Drive or an upload.
Emission factors
Whatever factor was copied in last year.
Gives a factor. Checking where it came from is up to you.
Published, versioned tables picked by the activity date, such as CEA v22 for India and DESNZ 2026 for the UK.
Where a figure came from
A cell. The trail lives in someone's inbox.
An answer in a chat, not tied to your records.
Trace this figure: the source document, what was read, the calculation and every report it appears in.
Missing data
Blank cells, found at audit time.
Can fill a gap with a plausible guess.
Says which months and sources are missing, and never fills them in.
What gets recorded without you
Anything anyone types.
Nothing. It has no access to your books.
Nothing until a person approves, unless you allow it per kind of work. 6 things always need a person.
The report
Assembled by hand every cycle.
Drafts text. The filing format is up to you.
BRSR Core, GHG Protocol and CBAM files built from the ledger, each anchored with a SHA-256 hash of its rows.
Routine work
Someone has to remember.
Only when you ask.
Autopilot routines for the monthly close, supplier chasers and regulatory watch, each asking before it records.
