The toolkit for IT
carbon accounting

One device or ten thousand. A calculator, an API, certificates, a dashboard. Everything has a source. Everything is built to be handed to your auditor without a follow-up email.

Core Engine

48 categories. Zero made-up numbers.

Laptops to UPS systems, switches to thin clients. The PAIA-aligned parametric engine takes specs in and gives emissions out — and every factor it uses traces back to EU MEErP, JRC, ADEME, or Fraunhofer IZM. No “industry averages” on the menu.

Full lifecycle: Production → Transport → Use Phase → End-of-Life
195+ country-specific electricity grid factors
Parametric BOM model — specs in, emissions out
Sub-linear scaling for Apple Silicon, ARM, and mobile SoCs

Every. Single. Factor. Has this.

Data Provenance

Click any number, land on the paper it came from

Every factor ships with a source URL, the document it came from, the publication year, and the methodology reference. When the question “where did this number come from?” arrives, the answer is one click away.

Certificates

Certificates that survive a phone scan

A4 PDFs with full lifecycle breakdowns, unique certificate numbers, and a QR code that goes to a public verification page. Your downstream buyer scans, your buyer's auditor scans, the breakdown is right there.

REST API

One `curl`and you're done

Eleven endpoints, an OpenAPI 3.1 spec, and the kind of error messages that read like a colleague wrote them. Plug into your ERP, CRM, or in-house ITAM tool. The batch endpoint takes 10,000 devices without flinching.

Dashboard

The dashboard your sustainability report copy-pastes from

Access Control

Access control that doesn't live in a wiki

Organization-scoped Postgres RLS, four role levels, and API keys that can't accidentally see another tenant's data. Your team sees what they should. Your auditor gets read-only. Nobody gets “oops” access.

Owner, Admin, Member, Viewer roles
Row-level security (Postgres RLS) — not application-level
Invite by email with tokenized links
API keys scoped to organization
Audit trail for compliance (who did what, when)

The four ways IT teams currently do this

An honest comparison. We're not the only option — we're the fastest one with sources you can verify.
