Carbon-OS · Product Carbon Footprint for automotive supply chains

One platform to collect, calculate, and report PCF, Tier 1 to Tier N.

A working concept of Climes Carbon-OS, mapped to the HAEI Product Carbon Footprint RFP.

Audit-grade supplier-tier data collection, an Ecoinvent-integrated calculation engine, and ISO 14067-aligned reporting, built to replicate HMI’s existing LCA methodology, not replace it. Everything below is interactive. Click through it.

suppliers, Tier 1–2, one workflow
The brief, in one line: digitise HMI’s manual LCA process into a secure, scalable, auditable platform, preserving the existing methodology, classification, and allocation logic, that collects PCF data across 300 Tier 1 and 1,200 Tier 2 suppliers, calculates automatically against Ecoinvent, and produces disclosure-ready reporting. That’s exactly the shape of Carbon-OS.
The problem we’re solving for

1,500 suppliers. One spreadsheet. That doesn’t scale.

HMI’s PCF process today runs on manual, fragmented workflows, email, spreadsheets, and offline follow-up across tiers. The result: limited traceability, slow supplier response, and low audit-readiness, right as CSRD, CSDDD, and BRSR raise the bar.

01

No centralised system

PCF data lives in inboxes and local files, not one platform of record.

02

Blind below Tier 1

Tier 2 and lower-tier contributions stay invisible until it’s too late to act.

03

Manual classification

DCT / FUT / COFF and CSP / MIP tagging done by hand, part by part.

04

IMDS trapped in PDFs

Raw material data re-keyed manually from static documents, every time.

05

No audit trail

Approvals, corrections, and version history go untracked across the chain.

06

Compliance is catching up fast

CSRD, CSDDD, and BRSR all need this data, and they need it soon.

How it works

Three layers. One audit trail, start to finish.

The same architecture that powers Carbon-OS for enterprise carbon accounting today, extended with an automotive-grade PCF/LCA module for supplier-tier collection.

LAYER 01

Collect

Tier 1 signs in through HyStar SSO; Tier 2 and below use secure, time-bound links, no new credentials.

  • HyStar SSO for Tier 1, OTP links for Tier 2
  • IMDS PDF parsed via OCR, editable after
  • Auto-classification: DCT / FUT / COFF
  • Manual CSP / MIP tagging where needed
  • Dynamic, versioned data-collection forms
LAYER 02

Calculate

Every validated submission runs a background calculation against Ecoinvent using HMI’s own allocation logic.

  • Ecoinvent as primary factor source
  • HMI methodology preserved, not redesigned
  • Factor version + input snapshot stored
  • Confidence: primary / secondary / estimated
  • Auto-recalculation on any data change
LAYER 03

Report

Part, supplier, and material views roll up automatically from L3 to L1, no separate reporting step.

  • Exploded L1 → L2 → L3 drill-down
  • Hotspot analysis by electricity, fuel, water
  • Supplier-, process-, material-wise views
  • Versioned, locked approvals
  • Excel & PDF export

Switch roles, build a part, cascade to Tier 2, and watch it calculate.

A working, in-browser simulation of the Collect → Calculate → Report flow, with the same role-based access the RFP asks for. Switch between Super Admin, Tier 1, Tier 2, and Auditor to see what each one can and can’t do. Nothing here touches a server; nothing persists after you close the tab.

Super Admin, create a part

Add a part under a vehicle model. Its weight contribution decides how the platform auto-classifies it, the same threshold logic as the RFP’s DCT / FUT / COFF rules.

3.0%DCT threshold: 5%+

Tier 1, submit process data

Pick a part, then submit raw material, process, and transport data, what a Tier 1 supplier fills in via HyStar SSO. For DCT parts you can cascade a secure link to Tier 2.

I don’t have process-specific data, use default / secondary values

Calculation engine & approval

Every submitted part runs a background calculation. In production this queries your licensed Ecoinvent database using HMI’s exact allocation logic, here it’s simulated. Only Super Admin can approve and lock a result.

Dashboards & hotspot analysis

Rolls up automatically from every calculated and approved part, no separate reporting step.

Demo mode uses illustrative emission factors, not licensed Ecoinvent data. Numbers are for interaction only, don’t quote them out of context.

Proposed delivery

Phased to your RFP, foundation first, automation later.

The RFP scopes three phases. Here’s how each maps to Carbon-OS. Phase 1 is the buildable core; Phases 2 and 3 extend it without re-architecting.
