Traceability as Proof of Origin
PDNA & EIFFAGE: A long-term partnership to verify materials across complex construction supply chains, linking material traceability to decarbonization objectives.
The Standard for Responsible Construction
.webp)
As a leading name in European construction, EIFFAGE delivers complex building and infrastructure projects while maintaining its reputation for sustainable and responsible practices.
Context
- In response to tightening environmental standards and rising expectations, the company has taken further steps, beginning with wood.
- Rather than relying on declarations alone, EIFFAGE voluntarily committed to a traceability system that links procurement with verifiable proof.
- To make this shift operational, consistent, and credible across projects, they partnered with PDNA.
A Dual Challenge
For Lasting Competitive Advantage:
Bid-Stage Traceability Design
Tailored traceability scope defined at bidding for product origin verification
Co-Product Supply Visibility
Oversight of co-products and by-products addressing supply chain weak links
Leveraging Traceability to Achieve Performance Goals
EIFFAGE aims at:
Informed decisions
Support informed purchasing decisions using reliable, high-volume project data for low-carbon choices
Risk Mitigation
Identify and mitigate supply chain risks across ESG and geopolitical dimensions
Operational Compliance
Maintain operational compliance with current and future regulatory requirements
Transparent Communication
Communicate and differentiate through responsible practices (important during tendering processes)
Solution: Proof of Origin & Transparent Communication
Example Wood Project: The Athletes' Village
- Tracking at the “component” level: Windows - Floors - Timber Frame Walls.
- Traceability integration as early as the tendering and technical documentation phases to meet client requirements.
- The Athletes' Village project along with all other traced projects, is publicly available on Eiffage’s platform for transparent communication.
