Environmental transparency

Environmental transparency in the construction sector—especially for timber products—is increasingly driven by Environmental Product Declarations (EPDs) and Life Cycle Assessments (LCAs). These tools provide standardized, third-party verified data about a product’s environmental impact across its entire life cycle.

🌱 What Is an EPD?

An Environmental Product Declaration (EPD) is a Type III environmental label that:

• Reports objective, comparable, and third-party verified data

• Is based on a Life Cycle Assessment (LCA)

• Follows international standards like ISO 14025, ISO 14040/44, and EN 15804 for construction products

EPDs are not eco-labels or marketing claims—they’re transparent disclosures of environmental performance, useful for procurement, certification (e.g. LEED), and regulatory compliance.

🔄 Lifecycle Data: The Backbone of EPDs

Lifecycle data is gathered through an LCA, which evaluates:

• Raw material extraction (e.g. forestry practices for timber)

• Manufacturing impacts (energy, emissions, waste)

• Transportation and installation

• Use phase (durability, maintenance)

• End-of-life (recycling, disposal, carbon sequestration)

This data helps identify hotspots for environmental improvement and supports benchmarking against similar products.

🪵 Why It Matters for Timber Products

Timber has unique sustainability advantages—like carbon storage and renewability—but also challenges like:

• Variability in sourcing practices

• Treatment chemicals and adhesives

• Fire resistance and durability concerns

EPDs help clarify these trade-offs and make timber products more competitive in green building markets.

✅ Benefits of EPDs for Timber Manufacturers

• 📊 Credibility: Third-party verification builds trust

• 🏗️ Market Access: Required for public procurement and green building certifications

• 🌍 Environmental Optimization: Identifies areas to reduce impact and improve efficiency

• 🔍 Transparency: Helps avoid greenwashing and supports informed decision-making
