Service Overview
Manufacturers are increasingly asked for consistent product-level environmental data by customers, specifiers, project teams and procurement programmes. Producing an EPD requires more than completing a template. The product scope, declared or functional unit, system boundary, data sources, allocation rules, LCA method, PCR and programme requirements must work together and remain traceable through independent review.
Desapex provides environmental product declaration consulting for manufacturers and product suppliers. We help define the intended market and product scope, organise primary manufacturing data, develop the LCA model and background report, prepare the public EPD document, and coordinate responses with an independent verifier and programme operator.
For construction products, the work can be aligned with the applicable PCR and EN 15804 requirements. LCA modelling is developed in accordance with the relevant methodology and programme rules, including ISO 14040 and ISO 14044 where applicable. The EPD itself is developed under the selected programme's ISO 14025 framework. Final applicability is confirmed during scoping because requirements vary by product, geography and programme.
The result is not simply a one-time PDF. Desapex can structure the underlying data, assumptions and evidence so they are easier to review, update and reuse for future declarations, product carbon-footprint work, customer questionnaires, embodied-carbon studies and digital product-data workflows.
What is an Environmental Product Declaration?
An Environmental Product Declaration (EPD) is a registered, third party-verified Type III declaration that reports a product's quantified environmental impacts across defined life-cycle stages. It is based on a life cycle assessment (LCA), follows applicable Product Category Rules (PCRs), and is developed within the rules of an EPD programme. An EPD reports transparent data; it is not a pass/fail sustainability certificate.
Our Digital-First Approach
Scope around the decision the EPD must support
We begin with the product, manufacturing sites, target markets, customer requests and intended programme. This prevents modelling from starting before the correct PCR, unit, boundary and publication route are understood.
Create a structured product-data workspace
We organise bills of materials, production volumes, energy, fuels, transport, packaging, water, waste and supplier information in controlled templates. Data owners, sources, reporting periods and evidence are recorded so gaps and assumptions remain visible.
Build a traceable LCA model
Primary and secondary data are mapped to the selected PCR and life-cycle modules. Allocation methods, cut-off rules, scenarios, datasets and calculation choices are documented to create a reviewable link from source data to reported indicators.
Use quality checks before verification
Completeness checks, unit checks, mass and energy balance reviews, variance checks and assumption logs are used before the verification submission. This helps reduce avoidable clarification cycles while keeping the independent verifier's role separate.
Hand over a reusable EPD data foundation
Alongside the declaration package, Desapex can organise the underlying data and documentation for future updates, additional products and connection with BIM, LCA or enterprise workflows where agreed in scope.
Core Deliverables
The final scope is tailored to the selected programme operator, PCR and product category. A typical engagement can include:
EPD strategy and scope note: product or product-family definition, business use case, target geography, intended audience and publication route.
PCR and programme-operator assessment: review of applicable, current PCRs and programme rules, with a documented recommendation.
Data-readiness assessment: required-data map, gap register, evidence checklist, reporting period, data-owner matrix and collection templates.
Life cycle inventory and LCA model: documented inputs, datasets, units, boundaries, allocation rules, scenarios and applicable life-cycle modules.
LCA background report: methodology, assumptions, data-quality review, calculations and supporting evidence prepared for independent verification.
Draft public EPD: programme-aligned narrative, product information, system-boundary description and environmental indicator tables.
Hotspot and scenario findings: interpretation of the main impact drivers and potential improvement areas, without making unsupported comparative claims.
Independent-verifier coordination: submission support, clarification tracking and response coordination. Verification remains the responsibility of the appointed independent verifier.
Programme registration support: final-file preparation and administrative coordination with the selected programme operator. Publication remains subject to the operator's requirements and approval.
Digital handover package: agreed source files, calculation records, assumption register, evidence index and update guidance.
A clear path from product data to published EPD
Discover and define: confirm the product, business objective, geography, PCR, programme and required life-cycle scope.
Collect and qualify data: gather primary and secondary data, identify gaps, document evidence and agree defensible assumptions.
Model and review the LCA: calculate the required indicators, check data quality and identify environmental hotspots.
Draft the EPD package: prepare the background report and public declaration in the selected programme's format.
Coordinate independent verification: manage questions and revisions while preserving verifier independence.
Support registration and handover: prepare approved files for publication and organise the underlying model for maintenance.
Why Choose Desapex
One coordinated EPD workflow
Desapex can manage the working process from early scoping and data readiness through LCA development, EPD drafting, verification coordination and registration support, reducing fragmented hand-offs for the manufacturer's internal team.
Digital-engineering context
EPD data often begins in bills of materials, design models, plant records and operational systems. Desapex's BIM and digital-engineering background helps us organise product information with future reuse in mind rather than treating the declaration as an isolated document.
Traceability built into the work
Sources, assumptions, allocation choices, scenarios and revisions are documented so the model can be reviewed and maintained. This supports a more efficient verification dialogue and clearer internal ownership.
Product and built-environment perspective
Desapex works across manufacturing, engineering and the built environment. That context helps connect product-level declarations with the information needs of designers, contractors, asset owners and whole-building LCA teams.
Independent roles kept clear
Desapex develops and coordinates the EPD package. The appointed independent verifier reviews it, and the selected programme operator controls registration and publication. The page should preserve this distinction in every claim and CTA.
Unique Selling Proposition
Desapex combines EPD consulting with digital engineering, turning fragmented product and plant data into a verification-ready declaration package and a structured information foundation that can support future updates and wider carbon-data needs.
Frequently Asked Questions
What is an Environmental Product Declaration?
An Environmental Product Declaration is a registered, third-party-verified Type III declaration that reports quantified environmental impacts for a product across defined life-cycle stages. It is based on an LCA, follows applicable PCRs, and is prepared under an EPD programme. It communicates data and does not by itself certify that a product is environmentally superior.
What is the difference between an LCA and an EPD?
How is an EPD developed, what data is required, and how long does it take?
Which standards, PCRs and life-cycle boundaries apply to an EPD?
Is an EPD a certificate, and who verifies and publishes it?
Are EPDs mandatory, and how can they support procurement or green-building projects?
