Verified Lifecycle Impact for Sustainable Products
An Environmental Product Declaration (EPD) is a standardized, third-party verified document that reports the environmental impacts of a product across its full life cycle – from raw materials and manufacturing to transport, use and end-of-life. Based on a robust Life Cycle Assessment (LCA) methodology, an EPD provides transparent, comparable and reliable data that aligns with recognised international standards such as EN 15804 and ISO 14025.
Arthian’s EPD consultants manage the full lifecycle of your Environmental Product Declaration – from early scoping through to final verification and publication. Our EPD consultants support manufacturers and suppliers across the construction and industrial sectors – from building materials, components and systems to engineered products and equipment. Whether you’re a manufacturer, distributor or product company needing verified data for procurement, WLCA compliance or broader environmental reporting, our consultants provide the expertise and guidance to deliver a robust, fully compliant EPD.
1. Product Scoping & Product Category Rules (PCR) Assessment
We begin by defining the product or product family requiring an EPD and identify the correct Product Category Rules (PCRs) aligned with EN 15804. Getting this stage right is essential – it sets the boundaries, methodology and structure your EPD must follow.
2. Data Collection Support
Data gathering is often the most challenging stage for manufacturers, so we make it as straightforward as possible. We support you to collect all necessary primary data, including material composition, energy consumption, water usage, waste streams, transport data and packaging information. We ensure the data is complete, consistent and verification ready.
3. Life Cycle Assessment (LCA for EPD) Modelling
Using industry-recognised LCA for EPD software and high-quality databases, our consultants model your product environmental impact across the required life-cycle stages. We identify hotspots, confirm system boundaries and ensure full alignment with EN 15804. This technical modelling forms the core component of your EPD and directly influences its credibility.
4. EPD Documentation Development
Once the LCA is complete, we translate the results into a fully compliant and clearly structured EPD documentation. This includes outlining the methodology, assumptions, scenarios, system boundaries and all mandatory environmental impact indicators. The document is prepared in the exact format required by your chosen programme operator, ensuring a smooth path to verification.
5. Independent Verification & Publication
Arthian coordinates the entire verification process with approved third-party verifiers and recognised Programme Operators. We respond to technical queries, make any required adjustments and ensure the EPD meets all compliance requirements. Once verified, we oversee registration and publication, so your EPD is ready for use across procurement, design and ESG reporting.
Choosing Arthian means gaining a partner that removes complexity, reduces risk and delivers a smoother, faster route to a fully verified EPD. Our consultants combine technical expertise, industry-approved tools and hands-on support to make the process easier for your team while ensuring every element meets the highest standards.
At Arthian, our team of EPD experts is well-versed in the challenges these projects face to get to the finish line, and we can help your team mitigate them. We offer:
An Environmental Product Declaration (EPD) is a standardized, third-party verified document that reports the environmental impacts of a product across its full life cycle – from raw materials and manufacturing to transport, use and end-of-life. An EPD reports the key environmental impacts of a product across its full lifecycle. These typically include:
EPDs are created using a strict set of international standards to ensure they are consistent, comparable and trusted. The key standards and guidance include:
Together, these standards ensure that every EPD is transparent, reliable and comparable across products and manufacturers.
Not always. Many manufacturers benefit from producing a product family EPD or a representative model, rather than creating individual EPDs for every product. Our EPD consultants will assess your product range, market requirements and client expectations to recommend the most cost-effective, credible and strategic approach. This ensures you meet industry needs without unnecessary expense or complexity.
Most EPDs take 8–16 weeks depending on data availability and product complexity. We provide a clear roadmap from day one.
Absolutely. If you have partial data, internal calculations or a previous LCA, we can pick up from where you are and build on it. Our consultants will validate your existing work, identify any data gaps and ensure everything aligns with EN 15804 and ISO 14025. This avoids duplicated effort, reduces costs and accelerates the path to a fully verified EPD.
Although closely related, Life Cycle Assessments (LCAs) and Environmental Product Declarations (EPDs) serve different purposes. Think of it as a two-step process:
1. LCA = the technical assessment (your product’s environmental performance is analysed in detail).
2. EPD = the verified declaration (the LCA results are standardised, third-party reviewed and published).
Without an LCA, you cannot produce an EPD. An LCA alone is not enough for most UK compliance or procurement processes. An EPD is what makes your environmental data credible, comparable and specification ready.
