We run the full EPD production process, data collection, LCA modelling, PCR compliance, third-party verification, programme operator submission, publication. What you get at the end is a verified, publicly registered EPD that holds up to scrutiny, commercially, technically, and under independent review.
An EPD is only worth having if the LCA behind it is rigorous, the Product Category Rules have been correctly applied, and the output has survived genuinely independent third-party verification. All three have to hold. We produce EPDs that meet all three on every project.
Before data collection or modelling begins, we establish the exact scope of the EPD. That means identifying the applicable Product Category Rules for your specific product type, reviewing them in full, and confirming the programme operator and verifier. We define the functional unit, declared unit, reference service life, system boundary and cut-off criteria against the PCR.
We put together a structured, product-specific data collection workbook and work with your production, procurement and facilities teams to gather what's needed annual energy by source and fuel type, raw material inputs with geographic origin, water consumption, waste by stream and disposal route, inbound and outbound transport.
We build the LCA model in SimaPro or OpenLCA and link your foreground data to background datasets from ecoinvent. Dataset selection is where a lot of EPD quality is actually determined using the wrong geographic or technological proxy can move a GWP result by 20% or more.
We produce the EPD document to the exact content and formatting requirements of the programme operator environmental performance results, additional environmental information, resource use, waste and output flows, end-of-life scenarios, and all required background information.
Every EPD has to be independently verified by a programme operator–recognised verifier before publication. A rigorous verifier will scrutinise dataset selections, system boundary decisions, PCR compliance, cut-off justifications, and the accuracy of your results.
Once verified, we manage registration and publication completing submission forms, uploading documentation, confirming correct listing on the programme operator's public database. Where relevant, we get the EPD listed on EC3.
SimaPro and OpenLCA are powerful calculation engines they store inventory data and compute environmental impacts once the model is built correctly. What they can't do is decide which background datasets fit your manufacturing process, determine where the system boundary should sit for your product category, interpret ambiguous PCR requirements, assess data quality, or build a documentation package that satisfies a rigorous verifier.
The question we hear most from manufacturers new to the process is why it takes twelve to sixteen weeks when the software runs in minutes. The timeline isn't about the modelling it's about primary data collection, which takes four to six weeks, and verification, which runs two to four rounds over four to eight weeks.
Beyond standard single-product EPDs, we offer the full spectrum of LCA and EPD services relevant to the US construction materials and building products market.
A dedicated EPD for a specific product the most common engagement. Covers all mandatory lifecycle stages as defined by the applicable PCR, with results independently verified and published under the relevant programme operator. Ideal for manufacturers responding to a specific customer requirement, project specification, or regulatory threshold.
A single EPD framework covering a family of similar products, rather than a dedicated EPD for each individual product line. Programme EPDs use defined product variants with environmental results presented for representative or bounding cases. Significantly more cost-efficient for manufacturers with multiple product variants.
A sector-average EPD produced by or for a trade association representing the average environmental profile of a product category across multiple manufacturers. Industry-wide EPDs satisfy LEED v4 credit requirements and provide a sector baseline against which individually produced EPDs can be compared.
Life cycle assessment covering Modules A1–A3: raw material extraction and processing, transport to manufacturing site, and manufacturing. This is the most common scope for construction product EPDs and satisfies the majority of Buy Clean and LEED material credit requirements.
Life cycle assessment extending through the complete product lifecycle, transport to site, installation, use phase, end-of-life deconstruction and disposal, and potential beyond-boundary credits from recycling and recovery. Required by certain PCRs and major whole-life carbon assessments.
EPDs have a validity period, typically five years under most programme operators, after which they must be renewed or withdrawn from the database. We manage renewals incorporating updated primary data, current background database versions, and any PCR revisions.
Product-level embodied carbon data to support GHG Protocol Scope 3 Category 1 reporting. We produce ISO 14040/44 compliant LCA studies that provide upstream carbon data needed for Scope 3 quantification and corporate sustainability disclosure.
Analysis of your product's Global Warming Potential results against applicable state and federal Buy Clean thresholds, confirming whether your product meets embodied carbon limits for California, Colorado, Oregon, Washington, or other state programmes.
For sustainability consultancies, environmental firms, and architecture and engineering practices, we act as your specialist EPD delivery partner, producing EPDs for your manufacturing clients under your brand on a straightforward subcontracting basis.
