Verified Product Data. Stronger Specification. Lower Carbon Impact.

Environmental Product Declarations (EPDs)

We provide Environmental Product Declaration (EPD) consultancy for manufacturers and construction product suppliers across the UK. Our team delivers EN 15804-compliant, third‑party verified EPDs that support specification, meet client requirements, and enable transparent carbon reporting.

What is an Environmental Product Declaration (EPD)?

An Environmental Product Declaration (EPD) is a standardised, third‑party verified document that reports the environmental impact of a product across its life cycle.

EPDs are based on a Life Cycle Assessment (LCA) and follow internationally recognised standards.

They typically include:

  • Global Warming Potential (GWP) (carbon emissions)

  • Resource use and energy demand

  • Water consumption

  • Waste generation and end-of-life impacts

EPDs enable consistent, comparable data for designers, contractors, and clients.

Why EPDs Matter in Construction

EPDs are increasingly required to support:

  • Product specification in low‑carbon design

  • BREEAM and sustainability certifications

  • Embodied carbon assessments and reporting

  • Net zero and ESG strategies

  • Procurement and client requirements

For manufacturers, an EPD provides a competitive advantage by demonstrating verified environmental performance.

Who Needs an EPD?

EPDs are valuable for:

  • Manufacturers of construction products

  • Material suppliers and distributors

  • Developers and contractors

  • Design teams specifying products

If your product is being assessed for embodied carbon or sustainability compliance, an EPD is often essential.

How to Get an EPD (UK Process)

  • Data Collection

    Gather product data, manufacturing inputs, and supply chain information

  • Life Cycle Assessment (LCA)

    Model environmental impacts in line with EN 15804 and ISO standards

  • Impact Calculation

    Quantify carbon (GWP) and other environmental indicators

  • Third‑Party Verification

    Independent review to ensure accuracy and compliance

  • Publication

    EPD issued and registered with a recognised programme operator

Standards & Compliance

To ensure compliance with UK and international programme operators, our EPDs align with:

EN 15804 (Construction Product EPDs)

ISO 14025 (Type III Environmental Declarations)

ISO 14040/44 (Life Cycle Assessment)

EPD vs LCA: What’s the Difference?

  • LCA (Life Cycle Assessment): Analytical process used to assess environmental impacts

  • EPD: A verified, published report based on LCA results

In short:

  • LCA = analysis

  • EPD = certified output used for specification and reporting

Delivering Verified Environmental Product Declarations for Specification and Carbon Transparency

Client: City Concepts
Sector: Construction Products (Glass Partitioning Systems)
Location: Crawley, UK
Service: Environmental Product Declarations (EPDs), Third-Party Verification

City Concepts partnered with Mainer to develop third-party verified Environmental Product Declarations (EPDs) across its glazing and partition system range. The aim was to provide transparent, measurable environmental data that would support sustainable specification, embodied carbon assessment, and stronger positioning in low-carbon construction.

Frequently Asked Questions

  • Costs depend on product complexity, data availability, and scope. Multi-product EPDs can improve cost efficiency.

  • Typically 6–12 weeks depending on data quality and verification timelines.

  • EPDs are not always mandatory but are increasingly required for specification, planning, and sustainability certifications.

  • EPDs for construction products follow EN 15804 and ISO 14025, based on Life Cycle Assessment standards.
