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.

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
Case Study: City Concepts - Verified EPDs for Commercial Glazing Systems
“Thanks to Mainer's dedication and expertise, we now have a comprehensive set of EPDs that align with our sustainability goals and enhance our value in the commercial fit-out sector. This will make a meaningful impact on our clients and future projects.”
— City Concepts
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.
