Understanding Environmental Product Declarations (EPDs) in Construction

Supporting informed specification through transparent environmental data

Environmental Product Declarations (EPDs) are becoming an increasingly important part of construction product selection, specification and embodied carbon assessment across the built environment.

As sustainability requirements continue to evolve, independently verified environmental data is helping provide greater transparency between manufacturers, distributors, specifiers and contractors. EPDs support informed decision-making through consistent lifecycle assessment methodologies and recognised international standards.

Cellecta’s verified EPD programme continues to expand across key gypsum-based flooring and acoustic systems, supporting transparent environmental product data for specification and material comparison.

What is an Environmental Product Declaration (EPD)?

An Environmental Product Declaration (EPD) is a third-party verified document that reports the environmental impact of a product across its lifecycle.

EPDs are developed using Life Cycle Assessment (LCA) methodologies and provide transparent environmental data relating to:

• raw material extraction

• manufacturing

• transportation

• embodied carbon

• lifecycle environmental impacts

Construction EPDs are commonly developed in accordance with:

• EN 15804

• ISO 14025

• ISO 14040 / 14044

Because EPDs follow standardised methodologies, they allow more accurate comparison between construction materials and systems.

Why EPDs Matter in Construction

Environmental Product Declarations are increasingly being used to support:

• embodied carbon assessments

• whole building lifecycle analysis

• material comparison and selection

• BREEAM assessments

• specification and procurement decisions

Independently verified environmental data is becoming more important throughout the construction supply chain as clients, designers and contractors seek greater transparency when selecting products and systems.

Rather than relying on broad sustainability claims, EPDs provide measurable and comparable environmental performance data.

Understanding EPD Data

Although EPDs contain detailed environmental information, several key areas are particularly important when reviewing and comparing products.

Global Warming Potential (GWP)

Global Warming Potential (GWP) measures the carbon impact associated with a product.

One of the primary areas reviewed within construction EPDs is the A1–A3 lifecycle stage, which includes:

• raw material extraction

• transportation

• manufacturing

These stages are often the main focus when comparing construction products and embodied carbon impacts.

Declared Unit

The declared unit provides the basis for comparison between products.

For example:

• per m²

• per m³

• per tonne

Ensuring products are compared using the same declared unit is essential for accurate environmental assessment.

Lifecycle Scope

EPDs may cover different lifecycle stages including:

• cradle-to-gate

• cradle-to-grave

• cradle-to-cradle

Understanding the lifecycle scope is important when comparing environmental performance between products.

Verification

Third-party verification is a key part of EPD credibility.

Cellecta’s Environmental Product Declaration has been independently verified in accordance with EN 15804 and ISO 14025, ensuring data is robust, transparent and developed using recognised international methodologies.

Supporting Sustainable Material Use

Cellecta gypsum-based products incorporate recycled gypsum fibre derived from industrial and construction waste streams.

These high-density, A1 non-combustible materials are designed to deliver strong acoustic and structural performance while supporting sustainable material use and circular construction principles.

Recovered gypsum can be processed through crushing, separation and sieving before being reintroduced into new construction products and materials, helping reduce reliance on virgin raw materials.

Using EPDs in Specification

As environmental requirements continue to evolve across the construction sector, EPDs are becoming an increasingly important part of informed specification.

Environmental product data can support:

• more accurate material comparison

• embodied carbon reporting

• lifecycle assessment

• sustainable procurement strategies

• specification confidence through independently verified data

For architects, consultants, contractors and distributors alike, EPDs help improve transparency throughout the supply chain.

Cellecta’s EPD Programme

Cellecta’s Environmental Product Declaration (EPD) programme continues to expand across key product ranges, supporting informed specification through independently verified environmental data.

Cellecta currently holds two verified EPDs covering selected gypsum-based flooring and acoustic systems, including:

• ScreedBoard® 20

• ScreedBoard® 28

• ScreedBoard® 30

• HiDECK Overlay 18

• HiDECK Acoustic Overlay 28

• HiDECK Structural 25

• HiDECK Structural 28

• HiDECK Structural 30

• FIBREfon 8

• FIBREfon 10

  
  

These EPDs have been developed in accordance with EN 15804 and ISO 14025 using Life Cycle Assessment (LCA) methodologies to provide transparent environmental performance data for specification and embodied carbon assessment.

Further environmental data development remains underway as part of Cellecta’s continued focus on product transparency and sustainable construction support.
