The challenge

CSRD compliance breaks on spreadsheets

The most common reasons a manufacturer's first ESRS E1 report stalls — or gets sent back by assurance.

Fragmented data across facilities

Utility bills, fuel logs, and refrigerant records scattered across email threads and local files — no single source of truth, no version control.

Methodology errors invalidate audits

Wrong GWP values, stale emission factors, or missing the LB/MB Scope 2 dual calculation — the findings that force report re-issuance.

Manual ESRS E1 assembly takes weeks

Sustainability managers hand-assemble E1-4, E1-5, E1-6 datapoints from five different systems before the first assurance conversation can even start.

The solution

A system of record for corporate emissions

Orca Carbon gives sustainability leads, plant controllers, and CFOs a single, auditable platform — from raw evidence to a signed ESRS E1 disclosure in hours, not weeks.

  • AI-powered extraction from utility bills, fuel invoices, and refrigerant logs
  • Scope 2 dual-method: location-based and market-based with EAC / Guarantee-of-Origin coverage
  • DEFRA 2024, IEA 2022, AIB, and IPCC AR5 GWP factors — current and traceable
  • One-click CSRD ESRS E1 statement — PDF export, structured for limited assurance
  • Hash-chained, immutable audit trail — every edit, factor, and approval recorded

Tamper-Evident Audit Trail

Every activity record, factor application, manual edit, and approval generates an immutable, hash-chained log entry. Assurers get a complete, tamper-evident chain of custody from raw bill to published figure.

How it works

From raw evidence to signed disclosure in four steps

No custom integrations required. Orca Carbon handles the full data lifecycle — import, calculate, track, and report.

1

Import & Extract

Upload utility bills, fuel invoices, and meter CSVs. Document AI extracts quantities and units automatically. Review flagged rows before committing.

2

Calculate

Factors (DEFRA / IEA / AIB / IPCC AR5 GWP) applied automatically. Scope 2 runs both location- and market-based methods. Every calculation is traceable.

3

Track & Target

Review facility-level breakdowns, YoY trends, and intensity metrics. Set SBTi-aligned reduction targets. Monitor completeness scores per site and period.

4

Report

Generate your ESRS E1 statement in one click. Export a PDF pre-populated with all E1-4, E1-5, and E1-6 datapoints — structured for limited assurance.

The CSRD requires in-scope companies to disclose a climate transition plan, energy mix, and a complete GHG inventory under ESRS E1. Orca Carbon maps every required datapoint to your inventory data and generates the disclosure automatically.

  • Organizational & operational boundaries (GHG Protocol)
  • Scope 2 location-based and market-based (E1-6 dual method)
  • GHG intensity per net revenue & per production unit (E1-6)
  • Reduction targets, transition plan & energy mix (E1-4 / E1-5)

Methodology

Rigorous science, not greenwashing

Every emission factor, GWP coefficient, and disclosure format traces back to a named, versioned standard — so your auditors can verify ours.

GHG Protocol Corporate Standard

Scope definitions, boundary-setting, and base-year recalculation follow the GHG Protocol Corporate Accounting and Reporting Standard (2015 revision).

DEFRA 2024 · IEA 2022 · AIB

Emission factors from DEFRA conversion factors (UK, 2024), IEA country electricity factors (2022), and the Association of Issuing Bodies for Scope 2 market-based.

IPCC AR5 GWP100 Values

Global warming potentials use the Fifth Assessment Report 100-year values (AR5, 2014).

GWP₁₀₀: CO₂=1 · CH₄=28 · N₂O=265 · R-410A=2,088

ESRS E1 · CSRD (EU) 2022/2464

Disclosure structure follows the European Sustainability Reporting Standard E1 (Climate Change) under the CSRD, in force for FY2025+ reporting. ESRS adopted via Delegated Regulation (EU) 2023/2772.

For container ports & terminals — the carbon pillar of Yeşil Liman

Türkiye's Green Port (Yeşil Liman) certificate requires a documented ISO 14064-1 greenhouse-gas inventory and evidenced reduction initiatives, assessed by an independent auditor. Orca Carbon builds that inventory — yard equipment, tugboats, reefer container power, and per-TEU emission intensity — structured for third-party verification, on the same tamper-evident audit trail as our CSRD reporting.

Common questions

What buyers need to know

The real objections, answered plainly.

Every activity record, emission-factor version, manual override, and approval generates an immutable, hash-chained log entry, and a coherence-validation gate blocks self-contradictory reports before approval — so your auditor gets a complete, defensible chain of custody from raw source document to published figure. The factors are sourced and versioned (DEFRA 2024, IEA 2022, AIB, IPCC AR5). The limited-assurance opinion itself is issued by your third-party auditor — Orca Carbon gives them the evidence trail to do it efficiently.
GHG Protocol Corporate Standard for scope definitions and boundary-setting. Emission factors: DEFRA 2024, IEA 2022 electricity factors, AIB for Scope 2 market-based. GWP values from IPCC AR5 (100-year, 2014). Regulatory reporting covers CSRD Directive (EU) 2022/2464 (ESRS set by Delegated Regulation (EU) 2023/2772) and ESRS E1 (E1-4 transition plan, E1-5 energy, E1-6 GHG inventory) with the full datapoint set required for FY2025+ wave-1 reporters.
Both, with AI as the accelerant. You can upload documents (PDF utility bills, fuel invoices, refrigerant logs) and Document AI (Mistral Pixtral vision model) extracts quantities, units, and periods automatically, flagging uncertain extractions for human review. You can also import CSV/XLSX meter readings or enter activity data manually. All three paths land in the same audited activity record table — there is no separate "AI data" vs "clean data" divide.
Location-based (LB) uses the average carbon intensity of the local electricity grid (IEA/national factors) — it reflects what the grid delivers regardless of what you buy. Market-based (MB) uses supplier- or contract-specific factors — if you hold Guarantees of Origin or EACs, your MB figure reflects that cleaner procurement. ESRS E1-6 requires both to be disclosed. Orca Carbon calculates both simultaneously from the same activity data — you never run a parallel process.
Data is stored on Hetzner infrastructure in the EU (Falkenstein, Germany). Tenant data is strictly isolated at the database level (row-level security — one tenant cannot see another's records even under a software bug). Documents are encrypted at rest. The audit trail is append-only at the infrastructure level. We do not sell or process your data for model training.
For a manufacturer with utility data already collected: a working ESRS E1 draft within a day of uploading source documents, assuming reasonable data quality. The bottleneck is typically not the software — it's data completeness (missing facility periods, unlabelled meter reads). The per-facility completeness dashboard surfaces exactly which periods have gaps before you commit the inventory, so you resolve blockers in parallel rather than during assurance.
