CDP Supply Chain · 2026 disclosure window
FY2025 supplier disclosure requests
are open. Don't get de-listed.
Your OEM customers are asking for Scope 1, 2, 3 data with installation-level lineage. If you can't respond with verifier-grade numbers, you're losing preferred-supplier status. VantageHSG produces the data the CDP questionnaire demands — per-part, per-billet, per-tonne.
Three paths
Which OEM customer is asking?
Automotive OEM (GM, Ford, Stellantis)
Per-part carbon footprint for Tier 1 and Tier 2 suppliers. Activity-based allocation from your actual production routing, machine time, and material inputs. Auto-formatted for OEM proprietary questionnaires.
Industrial OEM (steel, aluminum buyers)
Per-billet / per-coil embedded carbon. Installation-level mass balance from your actual blast furnace, EAF, or rolling mill data. Aligned with EU CBAM XML export when buyers are EU importers.
Retail / FMCG OEM
Facility-level Scope 1 + 2 with secondary-data Scope 3 for retailers without product-level granularity requirements. Aligned with the CDP Climate Change questionnaire format.
Active disclosure pressure
The 8 parent-company disclosure pressures on Ontario facilities in 2026.
These are the parent companies whose FY2025–FY2026 disclosure commitments are pulling Ontario facilities into Scope 1/2/3 data requests right now. If your facility is on this list and you're not yet producing verifier-grade installation-level data, you're at risk.
| Parent company | Ontario facility | What's driving the disclosure request |
|---|---|---|
| Novelis (Hindalco) | Novelis — Kingston | Supplier-specific Scope 1/2/3 requests to Canadian operations active for FY2025 forward. Primary EU auto-sheet customer base. |
| ArcelorMittal Dofasco | ArcelorMittal Dofasco — Hamilton | Reporting under IFRS, SASB, UNGC. Parent requires facility-level data for Dofasco's 60% reduction by 2030 commitment. |
| Stelco | Stelco — Hamilton | Publicly traded (TSX: STLC). Scope 3 disclosure expanding for FY2025. EAF route, lower OBPS exposure but still NPRI-reportable. |
| Heidelberg Materials | Heidelberg Materials — Picton | €226M Strategic Innovation Fund for CCUS at Edmonton cement (sister facility). Parent reporting is granular; CSRD pull-through applies. |
| Votorantim Cimentos | St Marys Cement — Bowmanville | Brazilian parent with TCFD-aligned reporting. St Marys Canadian operations pulled into scope. |
| CRH plc | Lafarge / CRH — Mississauga | Irish parent. Mandatory CSRD reporting from FY2024 onward affects Canadian operations through group consolidation. |
| Holcim | Holcim — Ontario operations | Swiss parent. CSRD reporting from FY2024 covering EU subsidiaries; Canadian operations in group consolidation. |
| Algoma Steel | Algoma Steel — Sault Ste. Marie | Publicly traded (TSX: ASTL). Blast-furnace route with EAF transition in progress. Major EU structural steel exporter. |

The 9-month runway starts now.
FY2026 CDP Supply Chain disclosure opens April 2027. Between now and then, install VantageHSG on one facility, prove the mass-balance reconciliation, and have the FY2025 numbers reproducible on demand. Then April 2027 is a data-pull, not a fire drill.
