Dura Composites designs and manufactures composite walkway and access systems supported by third-party verified Environmental Product Declarations (EPDs).

Our products provide embodied carbon data suitable for specification, whole-life carbon assessment and Scope 3 reporting across infrastructure projects.

The d² composite range is carbon-engineered by design, fully repurposable at end-of-use, and supported by lifecycle assessment data prepared in line with recognised international standards.

The d² Product Range: Engineered for Carbon Efficiency

Since the launch of re-engineered d² GRP Grating in 2019, we have saved:

2.3+ million

KG of raw materials

Compared with our former d¹ Grating (and legacy industry designs), d² has delivered:

10+ million

CO2e reduction

Safer. Stronger. Greener. Proven.

Our d² composite product range is intelligently carbon-engineered at source, using material efficiency, modular design and advanced manufacturing processes to minimise impact across the product lifecycle and support more responsible long-term asset strategies.

• Designed for lower embodied impact
• Long design life of up to 60 years
• Modular and lightweight for rapid installation
• Fully repurposable at end-of-use. Exclusively by Dura
• EPD-backed transparency

Sustainability You Can Specify with Confidence

We provide verified product data, standards alignment and material intelligence to support early design decisions, embodied‑carbon assessments and credible Scope 3 reporting without adding risk.

When required, we can produce project‑specific embodied‑carbon calculations for individual d² walkway products, using verified data that works with recognised assessment methodologies.

Our embodied‑carbon values for moulded and pultruded GRP and aluminium support whole‑life carbon assessments, project‑level calculations, informed material selection, sustainability reporting and alignment with environmental frameworks. This helps specifiers, consultants and contractors demonstrate due diligence and meet reporting obligations.

For guidance on reducing risk and simplifying composite specification across RIBA and PACE stages, designers and engineers can visit our Design Support page here.

Let’s Talk Embodied Carbon…

Whole life carbon refers to the total carbon emissions produced throughout the lifecycle of an asset or piece of infrastructure. These emissions come from the energy used to extract, transport and process raw materials, and to manufacture them into products used to build, maintain and renew assets. This is often known as Cradle to Gate.

To support transparency and measurable progress, we provide independently verified EPDs across our d² product range. These verified EPDs support accurate carbon reporting, strengthen project level sustainability planning and ensure alignment with recognised frameworks such as BREEAM, LEED and PAS 2080. Through this data led approach, we equip our customers with trusted insights to confidently monitor, manage and reduce their carbon emissions.

Scope of Assessment

Our EPD results have a cradle-to-gate scope, comprising raw materials extraction and supply (A1), transport (A2) and manufacturing (A3). The yellow highlights indicate the stages Dura Composites is involved in throughout the journey of the product.
