CarbonLedger

CarbonLedger helps small and mid-sized suppliers respond to customer carbon questionnaires without hiring consultants. It’s a web app with optional mobile capture that turns everyday operational data (utility bills, fuel receipts, shipment logs, production volumes) into a defensible, audit-ready footprint estimate aligned to common reporting expectations (Scope 1/2 and limited Scope 3 categories). The product focuses on “good enough to submit” accuracy: clear assumptions, versioned calculations, and evidence attachments so procurement teams can trust it. It also generates customer-specific exports (PDF + spreadsheet) mapped to typical supplier forms and ESG portals. This is not a magic button—data will still be messy—but it reduces the time sink from weeks to hours and prevents suppliers from losing deals due to non-compliance or slow responses.
