The construction sector has a data problem — and it’s quietly bleeding money from businesses that haven’t noticed yet.
Walk any major development site, and you’ll find architects who’ve specified materials without a clue what their embodied carbon looks like, developers who approved those specs without asking, and contractors who broke ground without anyone raising the question. For a long time, that was fine. Nobody was checking. That’s changed. If your business can’t produce a verified Environmental Product Declaration by 2027, tier-1 contractors, public procurement officers, and CSRD auditors will simply move on to someone who can. This isn’t speculation — France, Denmark, Sweden, and the EU procurement framework are already there. The US is catching up fast.
What an EPD Actually Measures — and Why It Matters
Think of an Environmental Product Declaration as a product’s carbon CV — independently verified, standardised, and impossible to fake. It’s built on Life Cycle Assessment (LCA) methodology under ISO 14044 and ISO 14040, which means a third party has signed off before it’s published. No self-reporting, no brand spin.
The minimum scope for most construction EPDs is cradle-to-gate (modules A1–A3): everything from raw material extraction through to the factory gate. That’s where the damage is done for concrete, steel, and insulation. By the time a lorry leaves the yard, the carbon is already in the atmosphere — and once those materials are installed, that footprint is permanent.
The numbers behind this aren’t small. Buildings and construction are responsible for roughly 39% of global energy-related carbon emissions. As grids get greener and buildings get more efficient, the operational side of that figure falls, which means embodied carbon becomes a bigger piece of what’s left. The World Green Building Council puts it plainly: without serious intervention, upfront carbon from new construction could account for nearly half of all new construction emissions by 2050.
Here’s something that doesn’t get talked about enough — the variation between similar products is enormous.
GWP Variation Across Similar Construction Products
| Product Category | Lowest GWP (kg CO₂/m²) | Highest GWP (kg CO₂/m²) | Difference |
| Rigid air barrier materials | −5.51 | +6.43 | >10 kg CO₂/m² |
| Internal lining products | Varies by material | — | Significant vs. standard |
Source: Industry LCA studies. Industry averages obscure this gap entirely — only product-specific EPD data surfaces
it.
That 10+ kg CO₂/m² swing between products in the same category is the kind of difference that determines whether a building hits its carbon target or misses it. Specifiers making material choices from generic datasets are essentially guessing.
Which brings us to the practical problem: producing EPD data properly is hard. Running a manual LCA — modelling impacts under ISO 14044, applying the right Product Category Rules (PCR), preparing a background report, going back and forth with a third-party verifier — is the sort of process that stalls on a spreadsheet the moment a compliance officer’s invoice arrives and someone more urgent needs attention. EPD software was built specifically to remove that bottleneck. It automates LCA modelling, integrates PCR requirements, and keeps the verification process moving — turning what used to be a drawn-out consultant engagement into something a team can actually manage at scale.
What Does an EPD Cost — and Is There an ROI?
Most sustainability content skips this part. CFOs don’t.
A single manually produced EPD — LCA consultancy, independent verification, registration — typically lands somewhere between £3,000 and £10,000, depending on product complexity and the EPD programme chosen. For a manufacturer with 30 product lines, that’s a serious budget conversation. Software changes the maths through automation and reusable LCA models, bringing per-product costs down substantially as volume increases.
The return side of that equation is increasingly well-documented. Businesses with verified EPDs in hand report:
- Faster procurement sign-off — specifiers aren’t chasing documentation that should already exist
- Access to public tenders that now mandate product-level environmental data as a baseline requirement
- Fewer deadline scrambles — having data ready is worth more than most teams realise until the first time a contract stalls because it isn’t
Put it this way: when a compliance officer rejects an invoice over missing EPD documentation, the cost of that delay almost always exceeds what the EPD would have cost to produce.
The Regulatory Tide Has Already Turned
There was a window — maybe five years ago — when EPDs were genuinely optional. A nice-to-have for LEED credits, appreciated by sustainability-forward clients, but not a requirement anywhere that mattered commercially. That window is closed.
EU and EEA public procurement bodies are now required to use EPDs when assessing products. France, Denmark, and Sweden have gone further with binding embodied carbon limits for new construction. The UK’s Net Zero Strategy brings the same expectation through whole-life carbon reporting requirements. Across the Atlantic, the Inflation Reduction Act has tied federal infrastructure funding to low-embodied-carbon materials — making EPD availability a commercial requirement in US federal markets, not just a European concern.
The market data reflects this shift. More than 9,000 new EPDs were published in 2025 alone. Over 83% of AEC professionals now rely on them when selecting materials. These aren’t early-adopter numbers anymore.
At the corporate reporting level, the EU’s CSRD has raised the stakes further. Large companies and listed SMEs must now disclose carbon data across their entire value chains — which under the GHG Protocol means Scope 1, 2, and 3 emissions. For construction businesses, Scope 3 is where most of the actual impact lives. EPD data is what makes those disclosures credible rather than aspirational.
Greenly, carbon accounting platform, connects both sides of this challenge — the product-level transparency that EPDs generate and the company-level carbon footprint measurement that investors and regulators are demanding under CSRD. A real decarbonisation strategy requires both. Showing up to a net zero commitment without verified data connecting product impacts to ESG reporting is, at this point, a liability rather than a differentiator.
How to Start Your LCA Journey: A 3-Step Checklist
For businesses that know they need to move but haven’t yet — the starting point doesn’t have to be a six-figure consultancy project.
Step 1 — Audit your catalogue. Which products show up most in green building tenders or public procurement? Those are your first EPD priorities. Start with cradle-to-gate; it’s the minimum scope required and captures the majority of material carbon anyway.
Step 2 — Match your tools to your volume. EN 15804 governs most European construction products — confirm which PCR applies to yours. If you’re producing EPDs for three or more products, a software platform will almost certainly cost less per EPD than a traditional consultant. Below that, a one-off engagement may make more sense.
Step 3 — Involve verification from day one. The most common reason EPD projects run over time is treating third-party verification as a final step. It isn’t. Software that structures your data with verifier review in mind throughout the process removes the longest delays.
TL;DR for Carbon Managers
- Compliance baseline: EPDs are the third-party verified gold standard for product carbon data (ISO 14025) — 83% of AEC professionals now use them for material selection
- Market access: Without an EPD, public procurement in the EU, UK, and increasingly the US becomes inaccessible
- Cost reality: Manual EPDs run £3,000–£10,000 each; software cuts that significantly at scale
- CSRD link: Scope 3 disclosures need product-level data — EPDs are what make those numbers hold up
- 2030 target: The WorldGBC’s 40% embodied carbon reduction goal is only achievable if measurement infrastructure exists to support it
