Environmental Product Declarations for Building Products — What Architects Need and Why Manufacturers Can’t Afford to Skip Them
If you’ve been in a specification meeting in the last five years and haven’t heard the term EPD, you will soon.
Environmental Product Declarations are no longer a niche sustainability requirement for LEED-chasing firms on high-profile projects. They are becoming a baseline expectation across commercial construction. Manufacturers who don’t have them are starting to lose specifications to the ones who do.
Here’s what an EPD actually is, why architects are asking for them, and why your product needs one.
What Is an Environmental Product Declaration?
An Environmental Product Declaration for building products, often referred to as a Type III EPD, is a standardized, third-party verified document that quantifies the environmental impact of a building product across its entire lifecycle.
It is not a marketing brochure. Not a sustainability claim. It is a technical document based on a Life Cycle Assessment. Measuring the actual environmental footprint of a product from raw material extraction through manufacturing, transportation, installation, use, and end of life.
An EPD reports environmental impact across multiple categories:
- Global warming potential — the carbon footprint of the product measured in CO2 equivalent. Ozone depletion potential. Acidification potential. Eutrophication potential. Smog formation potential. Depletion of non-renewable energy resources.
Every EPD follows a standardized format governed by ISO 14025 and EN 15804, verified by an independent third-party program operator, and registered in a public database. The data is transparent, comparable, and defensible.
That last word. Defensible. Is the one that matters most to architects.
Why Architects Are Asking for EPDs
Architects don’t ask for EPDs because they’re interested in sustainability as a concept. They ask for them because their clients are requiring it, their rating systems are requiring it, and increasingly their contracts are requiring it.
Here’s what’s driving the demand:
LEED v4 and v4.1
LEED v4 introduced mandatory EPD requirements for the first time. To earn credits under the Building Product Disclosure and Optimization category, projects must document EPDs for at least twenty permanently installed products from at least five different manufacturers. That credit requirement created an overnight market for EPDs across every product category in commercial construction.
Living Building Challenge and other rating systems
The Living Building Challenge, WELL Building Standard, and a growing list of regional green building programs all reference EPDs as either required or preferred documentation. As these programs gain traction — particularly in institutional, healthcare, and education markets — EPD requirements follow.
Buy Clean legislation
California’s Buy Clean California Act — the first of its kind in the United States — requires state-funded construction projects to source certain materials from manufacturers who can demonstrate low embodied carbon through EPDs. Similar legislation is advancing in other states. Federal procurement is moving in the same direction. For manufacturers selling into publicly funded construction, an EPD is becoming a legal prerequisite to bid.
Embodied carbon commitments
Architecture firms are making net-zero embodied carbon commitments at a pace that would have been unimaginable a decade ago. Those commitments require data. EPDs provide it. A firm that has committed to tracking and reducing the embodied carbon of every project they design cannot specify a product that has no EPD — because they have no data to work with.
Specifiers who simply prefer documented products
Beyond rating systems and legislation, there is a growing population of specifiers who have made EPDs a baseline preference — not a requirement, a preference. When two comparable products are on the table and one has a third-party verified EPD and one doesn’t, the one with the EPD gets specified. Every time.
Why Building Product Manufacturers Need an EPD
If your product is sold into commercial construction and you don’t have an EPD, you are losing specifications you don’t know you’re losing.
The architect doesn’t call to tell you. They don’t send an email explaining that your product was removed from consideration. They simply open the specification section, look at the submittal requirements, see that an EPD is listed as required documentation, and move to a competitor who has one.
That’s it. No conversation. No second chance.
Here’s why getting your EPD done now matters:
The specification is written before the project starts.
By the time a contractor is calling manufacturers for pricing, the specification has already been written. The products that made it into the spec made it there because the architect could document them. Products without EPDs get designed out before anyone picks up the phone.
Your competitors are getting theirs done.
EPD adoption across the building products industry is accelerating. The manufacturers who move early establish a documented environmental profile that becomes part of their brand. The ones who wait are playing catch-up in a market that is moving without them.
Rating system credits are project currency.
When a specifier is assembling a product list for a LEED v4 project, every product with an EPD contributes to the credit threshold. A manufacturer with an EPD gets pulled onto the list. A manufacturer without one gets passed over — not because their product is inferior, but because it can’t contribute to the credit.
Embodied carbon is becoming a procurement criterion.
As Buy Clean legislation expands and corporate sustainability commitments tighten, the question will stop being “do you have an EPD” and start being “what is your global warming potential number.” Manufacturers who have EPDs already have that number. Manufacturers who don’t have nothing to offer when the question gets asked.
It is a one-time investment with multi-year returns.
An EPD is valid for 5 years. The investment in the Life Cycle Assessment and third-party verification is made once. The return — specifications won, products that survive the sustainability documentation review, credibility in a market that is increasingly requiring transparency — compounds across every project your product touches for the next five years.
What the EPD Process Looks Like
An EPD doesn’t happen overnight — but it doesn’t have to be complicated either.
The process starts with a Life Cycle Assessment conducted according to a Product Category Rule — PCR — specific to your product type. The PCR defines what data gets collected, how it gets analyzed, and how the environmental impact is calculated. The LCA is then reviewed and verified by an independent third-party program operator and registered in a publicly accessible EPD database.
From start to finish, a professionally managed EPD process typically takes eight to sixteen weeks depending on the complexity of your product and the availability of your manufacturing data.
What you need to provide: manufacturing process data, raw material inputs, energy consumption figures, transportation distances, and waste generation data. A qualified EPD consultant manages the LCA methodology, the PCR compliance, the third-party verification submission, and the registration process.
ZeroDocs manages EPD development for building product manufacturers — from initial data collection through third-party verification and database registration. If your product needs an EPD and you’re not sure where to start, that’s exactly what we do.
The Bottom Line
Environmental Product Declarations for building products are not a sustainability trend that may or may not stick.
They are a procurement requirement that is expanding — across rating systems, across legislation, across the specification decisions of individual architects who have decided that undocumented products are not worth the risk.
The manufacturers who have EPDs are getting specified.
The ones who don’t are getting designed out.
If your product is sold into commercial construction and you don’t have an EPD, the question isn’t whether you need one.
It’s how many specifications you’ve already lost without knowing it.
