Can you back your sustainability claims?

A four-point checklist for sourcing building materials that hold up under scrutiny 

In today’s market, it’s not enough to say a material is “responsibly sourced” or “better for the environment.” Project teams are expected to produce defensible documentation. Government contracts, regional code requirements, rating systems, and clients who treat sustainability as a procurement requirement—not a preference—are driving that expectation.

Under those conditions, material selection is as much about verification and compliance as it is about performance. When the sourcing story is clear and the disclosures are already in a review-ready format, architects can avoid late-stage rewrites, reduce the risk of rejected submittals, and protect design intent throughout the process.

In some cases—Real Cedar being a strong example—you can get the best of both worlds: an appearance material with the warmth and character designers want, supported by the third‑party and institutional signals sophisticated stakeholders look for.

The following four criteria offer a practical way to evaluate whether a product’s environmental story is verifiable, comparable, and defensible.

Third-Party Certification

Forest certification does more than signal “good practice”—it translates sustainable forestry into independent verification. Third‑party programs assess whether forest management protects core environmental values that matter to owners and project teams. This includes biodiversity and soil and water protection. Many also include product labeling and chain‑of‑custody. This is what keeps a sourcing claim intact as material moves from forest to mill to distributor to job site. It’s also what makes it easier to stand behind during submittals.

Real Cedar is well positioned to meet that burden. One of the primary source regions for Western Red Cedar is British Columbia. And more than 85% of BC timberland is certified by internationally recognized third parties. As of 2023, B.C. reported 45 million hectares of certified land.

In practice, Real Cedar producers and supply chains commonly align with widely recognized frameworks used in the U.S. and Canada. This includes FSC, SFI, and CSA (with ISO 14001 often used for environmental management systems and ATFS relevant to certified U.S. family forestlands). For specifiers, the advantage is simple: documentation that is review‑ready.

Independent LCAs and EPDs

Materials backed by independent life-cycle assessments (LCAs) and environmental product declarations (EPDs) make specification easier by replacing broad sustainability language with documentation reviewers can evaluate. A robust LCA tracks impacts from cradle to grave.  And when designed for comparative use, it sets a consistent basis for evaluating a product against common alternatives. When questions arise during design review, value engineering, or submittals, standardized life-cycle disclosure supports clearer side-by-side comparisons —and faster answers—under procurement pressure.

Real Cedar has that level of substantiation readily available. The Western Red Cedar Lumber Association (WRCLA) commissioned this type of third-party LCA research (later updated by FPInnovations). These reports evaluate Western Red Cedar siding, timber and decking alongside common alternatives. They inform a Type III EPD developed to ISO-aligned standards and product category rules. For project teams, that means they can document, discuss, and defend impacts in a review-ready format when requirements are nonnegotiable.

Jurisdictional Assurance

When sustainability claims have to withstand review, provenance matters. Sourcing from jurisdictions with clear oversight and enforcement gives specifiers a firmer baseline. That’s because responsible management is shaped by systems—not just voluntary commitments. In British Columbia, forest management is informed by scientific research, planning and standards, and public consultation, supported by a framework of laws, monitoring, and enforcement.

Similar indicators appear in the U.S. as well, including forest growth that can exceed harvest, a larger forest resource than mid‑century levels, and roughly 300 million acres of certified forestland. The takeaway? When you specify Real Cedar, your sourcing claim is anchored in regions where expectations are codified and auditable. 

Affiliations with Trusted Associations 

In specification, credibility often comes from the company a product keeps. Beyond certifications and disclosures, affiliation with a credible, long-running trade association can signal an industry’s commitment to shared standards.

For Real Cedar, that association is the WRCLA established in 1954 as a non-profit voice for the cedar industry. WRCLA represents a broad network across the supply chain—primary manufacturers, remanufacturers, distributors, retailers, and other partners. All organized around a common goal of advancing Western Red Cedar for the long term. But WRCLA’s role isn’t limited to promotion. It also supports research- and data-informed market education, develops technical and educational resources, and provides direct technical support—helping keep performance claims, guidance, and documentation consistent as products move from industry messaging into drawings, specs, and submittals.

Conclusion

A credible record includes third‑party verification, comparable life‑cycle disclosure, sourcing grounded in well‑governed forestry systems, and an industry association that sustains education and technical guidance.

The advantage of an established material isn’t only that claims are easier to support; it’s that there are fewer unknowns. So teams can focus on design and detailing instead of rebuilding the rationale at each project milestone. In that context, Real Cedar equips teams with third-party, review-ready information they can compare and cite through design review and submittals.
