About Emistra

Built by engineers.
Grounded in regulation.

Emistra was built to solve a specific technology problem: the data companies need for ESG reporting already lives in their ERP systems, but no software had built a real, direct connection between them. We built that connection.

Our story

We saw a data infrastructure problem. So we built the solution.

Emissions data doesn't start on a sustainability spreadsheet. It starts as a fuel invoice, a utility bill, a freight booking, a purchase order. All of that data already exists inside an ERP system — SAP, Oracle, Dynamics 365, Xero. Yet every ESG reporting workflow we observed required someone to manually re-enter it. Twice.

Emistra was founded on the premise that this is a technology failure, not a compliance failure. The data is there. The frameworks are published. The gap is software that connects them with the accuracy and auditability that regulators now demand.

We are not ESG consultants and we don't claim to be. What we are is a team of software engineers who take regulatory accuracy seriously — who read the ESRS standards, the GHG Protocol guidance, the DEFRA emission factor documentation — and build systems that implement them correctly, with a verifiable audit trail at every step.

A note on transparency: Emistra is a young company. We don't have a roster of enterprise case studies yet — we're building our first reference customers now. What we do have is software built to a professional standard, mapped directly to published regulatory requirements, with an immutable SHA-256 hash-chain audit trail designed to satisfy CSRD limited assurance from day one. We'd rather prove that with a hands-on demo than promise it with stock photography.

What we stand for

Three things we refuse to compromise on

Every product decision at Emistra comes back to these three principles.

Regulatory Accuracy

Every framework, every emission factor, every disclosure requirement in Emistra is mapped directly to the published regulatory text — ESRS, GHG Protocol, GRI, ISSB, EU Taxonomy. We don't interpret standards; we implement them as written and link every calculation back to its source.

Data Integrity

An ESG report is only as credible as the data behind it. Every ERP-imported entry in Emistra is locked into a SHA-256 hash-chain audit trail — immutable, timestamped, traceable back to the original transaction. Auditors can verify any figure without contacting us.

Real Integration, Not Workarounds

Most ESG tools call a CSV export an "integration". Emistra connects via real-time webhooks — SAP S/4HANA, Oracle ERP Cloud, Dynamics 365, Xero, QuickBooks — so emission entries appear as transactions happen, not after a weekly export cycle.

How we work

We work with the standards, not around them

Where ESG requires domain expertise — interpreting a new ESRS delegated act, aligning with EFRAG's latest implementation guidance — we consult the primary regulatory documents and, where needed, external specialists. Our job is to translate that expertise into software that enforces it consistently at scale.

  • Every supported standard is cross-referenced to the official published text (EFRAG, ISSB, GRI, GHG Protocol, EU OJ).
  • Emission factor databases (DEFRA, EMBER, EPA, EXIOBASE) are versioned and updated when official revisions are published.
  • Calculation logic is transparent: every GHG figure shows the activity data, emission factor, source database, and calculation formula used.
  • Framework coverage is verified against actual disclosure requirements — not marketing checkboxes.
  • Our CSRD audit trail is designed specifically to meet the ISAE 3000 limited assurance standard required under CSRD.
  • We ship new framework coverage when official guidance is finalised — not when it's announced.
