New graphene rules boost sustainable concrete potential

A new set of Product Category Rules (PCR) for graphene and graphene-based products has been published, creating a framework for transparent sustainability reporting and paving the way for wider adoption in construction materials.

The PCRs establish how producers can carry out Life Cycle Assessments (LCAs) and prepare Environmental Product Declarations (EPDs) in line with ISO 14044. This gives the industry a standardised approach to demonstrating environmental impacts such as carbon footprint.

For the concrete sector, the rules are significant. Graphene is already being trialled in admixtures and cement-based products to increase strength and durability, reduce cement content, and lower embodied carbon. With reliable EPD data now available, graphene-enhanced products can be more easily assessed against traditional solutions, supporting procurement and compliance under UK sustainability frameworks.

Terrance Barkan, executive director of the Advanced Carbons Council, said: “As industries face growing pressure to demonstrate sustainability, the ability to provide robust, standardised data has become not only a compliance requirement but also a competitive advantage.”

The council said the new rules would help position graphene as a sustainable option in sectors including construction, where transparent carbon reporting is now expected.

Graphene in Concrete – Potential Benefits at a Glance

• Higher strength – improves tensile and compressive performance.
• Cement reduction – allows lower clinker content without loss of strength.
• Durability – enhances resistance to cracking, water ingress and chemical attack.
• Carbon savings – supports lower embodied CO₂ by reducing cement use.
• Faster curing – accelerates hydration, potentially shortening construction times.
• Versatility – can be added as an admixture, coating, or reinforcement in precast and ready-mix.
