Signals the recipient responds to

Organisational context

Positions
IETA VCM WG sets the industry alignment on voluntary-market integrity reform.
Active initiatives
CCP alignment; corporate-buyer guidance; registry-interoperability.
Pressures
Shift of corporate-buyer value to high-integrity tonnes; registry consolidation.

Specific alignment

Why this recipient benefits: WG position paper framing property-based disclosure as the operational convergence property across major registries aligns the VCM to proof-pack-readiness. Shopley's corporate-buyer framing + Puhl's methodology depth gives the paper technical and strategic credibility.

Why now: IETA annual conference.

The ask: WG position paper. Registry-interoperability schema; corporate-buyer procurement-policy analysis.

Working group
IETA Voluntary Carbon Markets (VCM) Working Group

Focus

Alignment and reform of voluntary carbon markets: integrity principles, registry interoperability, corporate buyer guidance.

The ask

VCM WG endorsement of per-tonne evidentiary disclosure as a convergence property across major registries.

Deliverable

WG position paper on property-based disclosure as the operational route to VCM integrity.

Why IETA is the right venue

IETA is the business voice of the emissions-trading industry. IETA working-group endorsement of per-tonne evidentiary disclosure translates immediately into uptake by member companies — traders, project developers, verification firms, and corporate offtake buyers. The ~300 IETA members are also the actors who will price proof-pack-equipped credits once they exist.

The three org-level IETA documents — the Integration Whitepaper, Partnership Proposal, and Technology Alignment Analysis — should be presented at the relevant working group rather than at the board level first. Working-group-level engagement is where the technical acceptance happens; board-level engagement is where the organisational endorsement follows.
