ESG reporting your auditors can actually defend

Pull ESG metrics from operational systems, document the methodology, and produce auditor-ready disclosures—without parallel spreadsheet workflows.

The problem

ESG reporting still runs on side spreadsheets

  • ESG data is scattered across ops systems

    Emissions, water, energy, safety, and supplier data live in plant systems, ERPs, HRIS, and supplier portals. Every cycle, sustainability teams chase the same files from the same people.

  • Methodology isn't documented for audit

    Calculation logic—emission factors, allocation rules, scope boundaries—lives in analyst heads and individual spreadsheets. Auditors ask how the number was built; the answer takes weeks to reconstruct.

  • Manual consolidation each cycle

    Disclosure preparation is a multi-week exercise of copying, reconciling, and footnoting. The same checks get redone every period because nothing is operationalized.

  • No version control on disclosed numbers

    Once a metric goes into a public disclosure, restating it later is painful—there's no clean record of which inputs, methodology version, and approvals produced the number that was filed.

How it works

A governed ESG layer your sustainability team owns

Step 1

Ingest from source

Plant systems, ERP, HRIS, and supplier feeds normalized into a single governed ESG dataset—refreshed on the cadence reporting actually needs.

Step 2

Apply methodology

Versioned methodology library (GHG protocol, GRI, CSRD) applied with full lineage: every metric traces to inputs, factors, allocation rules, and approver.

Step 3

Generate & defend

Auditor-ready disclosures generated from governed data, with exception workflows for restatements and a documented trail for assurance reviews.

Flow is adapted to your reporting frameworks, ERP, and operational data sources.

ESG reporting your auditors can actually defend

What's included

ESG disclosuresyour auditors can defend

Data, methodology, and disclosures in a single governed layer—delivered on Synapse with sustainability-owned controls and CSRD-ready lineage from day one.

ESG data ingestion from ops

Direct connectors to plant systems, ERP, HRIS, and supplier portals—no more chasing files each cycle.

Methodology library

Versioned GHG protocol (Scope 1/2/3), GRI, and CSRD calculation logic—maintained centrally, applied consistently across entities.

Disclosure generation

Framework-aligned disclosures (CSRD, ISSB, GRI, SASB) generated from governed data with footnotes and methodology references.

Audit trail with data lineage

Every disclosed metric traces back to source records, factors, methodology version, and approver—ready for assurance review.

Exception workflows

Restatements, gap-filling, and estimate substitutions captured with reason codes and reviewer trail—nothing happens off-system.

ERP integration

Native connectors to SAP, Oracle, and major HRIS platforms—ESG data lives where finance and operations already work.

less time on manual consolidation each reporting cycle

Orientative—based on early implementations.

Full

lineage from disclosed metric back to source record and methodology version

Audit-ready

evidence pack generated automatically for assurance reviews

Orientative—depends on assurance scope and framework.

How we work

From first call to audit-ready disclosures—without the usual drag

Assess

Week 1–2

Map current ESG data sources, methodology gaps, reporting frameworks in scope, and the disclosures the team must defend.

Design

Week 3–5

Define metric hierarchy, methodology library, approval gates, and the disclosure templates aligned to CSRD, ISSB, GRI.

Build

Week 6–10

Integrate operational systems, codify methodology with finance and sustainability, validate against prior cycles, design the approval UX.

Govern & scale

Week 11+

Assurance sign-off, sustainability-owned operations, expand frameworks and entity scope by cycle.

Timelines vary by ERP complexity, reporting framework scope, and assurance requirements.
