Meeting prep for Stela Ivanova + IDDI Secretariat + Jack Fraser. Core move: propose a WG II interoperability track connecting product GHG standards, ISO/EN EPD rules and procurement guidance.
Introductory alignment with Jack Fraser, IDDI’s new GHG standards specialist.
Give Jack a concrete, high-value first assignment: product standards + EPD interoperability for GPP.
Warm welcome, fast orientation, then operational: “Can we turn this into a July-ready WG II output?”
Position Germany as the bridge between EU policy, industrial standards and real procurement language.
Dietram and Stela missed the April Steering Committee; materials reshared via Basecamp. Next SC: July 2026.
GPP Criteria Survey + Guidance EU session on 28 May; APAC session on 2 June.
Procurement guidance should be clear for officers; technical harmonization stays in WG II.
Useful bridge: “This is exactly where a standards interoperability note can help.”
Core question: what minimum information must a product-level carbon claim or EPD contain so governments can use it for low-emission steel, cement and concrete procurement across jurisdictions?
GHG Protocol Product Standard, ISO 14067, EN 15804 / EPDs, IDDI PCR guidance.
Boundary, unit, modules, data quality, verification and comparability into GPP language.
Steel first, cement/concrete second; include EU and India to avoid Eurocentric guidance.

“With GHG Protocol and ISO moving toward updated harmonized product-level GHG accounting, and EPD frameworks already heavily used in construction, IDDI can provide the procurement and heavy-industry use case. WG II could map GHG Protocol Product Standard, ISO 14067, EN 15804/EPDs and IDDI PCR guidance into a practical interoperability matrix for steel, cement and concrete.”
Aim: not to declare them equivalent, but to say what governments can safely reference in GPP criteria.
Jack + Dietram outline 2-page issue note and matrix headings.
Use GPP Criteria Survey discussions to validate procurement questions.
Present matrix v0.1 and ask for mandate / contributors.
Do not say “EPDs are enough.” Say: EPDs are useful only when PCR, boundaries, data rules and verification support comparison.
