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.

Note:The 2026 CDP Supply Chain disclosure window opened April 27, 2026 and closed June 15, 2026. If you missed it, you're now in catch-up mode for the FY2026 cycle (opens April 2027). The 9-month runway is the right time to install VantageHSG — not scramble again with a 3-week spreadsheet rebuild.

Three paths

Which OEM customer is asking?

A

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.

See: Automotive parts industry page →

B

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.

See: Steel industry page → · CBAM exporters →

C

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.

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.
