Your Scope 1–2–3 ledger.
CSRD-ready in weeks,
not quarters.
CarbSynq connects procurement invoices, energy meters, and logistics data into a single auditable carbon ledger — and generates your ESRS E1 disclosures automatically.
The typical CSRD path costs €80–150K and 6 months.
Most mid-caps still rely on consultancy-led data collection: manual Excel templates, supplier questionnaires sent to 200+ vendors, and 3 rounds of auditor review of the resulting spreadsheets. CarbSynq is a carbon accounting platform — not a consultancy. We replace the data collection work; we do not replace your auditor or your sustainability strategy.
From raw data to CSRD disclosure in three steps
No consultants. No spreadsheet marathons. Just automated, auditable carbon accounting.
Connect your data sources
Link procurement systems, energy meters, and logistics APIs. CarbSynq normalizes formats automatically.
Unified emissions ledger
Every Scope 1, 2, and 3 emission is classified, attributed, and stored with full audit lineage.
Generate CSRD disclosures
Export ESRS E1-compliant reports and EU Taxonomy KPI tables — audit-ready, every quarter.
The ledger your auditors will trust
Real-time Scope 1-2-3 tracking with quarterly trend analysis and CSRD disclosure status — all in one dashboard.
Complete Scope 1, 2, and 3 coverage
From direct combustion to upstream supplier emissions — every category the ESRS E1 requires, automated from your existing data.
Direct emissions
Combustion, company vehicles, industrial processes — from meter reads and utility invoices. Full GHG Protocol Category 1 alignment.
Energy emissions
Market-based and location-based electricity, heat, steam — from supplier invoices and grid emission factor databases.
Value chain emissions
All 15 GHG Protocol categories — purchased goods, logistics, business travel, waste — from procurement data and telematics APIs.
Trusted by sustainability leads across European mid-caps
We had four months of manual data-collection work ahead of us before we found CarbSynq. After connecting our SAP procurement data, the Scope 3 Category 1 baseline was populated in two days. Our ESRS E1 assurance provider accepted the ledger without requesting a single source restatement.
Our Scope 3 Category 1 spend-based estimate was completely wrong — our procurement categories didn't map to UNSPSC codes we could use. CarbSynq's commodity classification engine reclassified 8,400 invoice lines overnight and the emission factor assignments are traceable to Ecoinvent 3.10 sources. Six weeks of analyst time avoided.
Before signing the CSRD disclosure I needed every tCO₂e figure to trace back to a specific source document. Most carbon tools give you a number; CarbSynq gives you a number and a full data lineage. That is what our auditor needed to issue limited assurance without additional fieldwork.
