Stuart Nicholson, Managing Director of Marley, highlights how a groundbreaking concrete roof tile is setting a new standard in the UK roofing industry.
The UK construction industry is under mounting pressure to meet stringent net zero carbon targets. Driven by frameworks such as the Future Homes Standard, regulations now increasingly require builders and developers to provide evidence that their materials and practices genuinely contribute to reducing the carbon footprint of construction projects.
This puts the onus on specifiers and sustainability leads to verify claims of carbon neutrality, while also seeing manufacturers use innovative materials and production methods which genuinely lower emissions.
To address these demands, Marley has introduced the Edgemere 2.0 into its well-established Edgemere concrete roof tile portfolio.
What sets Edgemere 2.0 apart, however, is its integration of advanced carbon-capture technology combined with independently verified carbon tracking via the Carbon Bank system.
This marks a UK first in the roofing sector, offering verifiable assurance of its carbon reduction credentials.
This leap forward is made possible by Heidelberg Materials’ evoZero® cement technology, a near-zero-carbon product that leverages cutting-edge carbon capture and storage (CCS) systems.
evoZero® cement is produced using CCS technology at Heidelberg’s Brevik facility in Norway. During manufacturing, CO₂ emissions are captured at source before they escape into the atmosphere. The captured carbon is then securely stored beneath the seabed. A digital ledger system known as the Carbon Bank records these emissions reductions, providing transparent tracking throughout the product lifecycle.
Every batch of evoZero® cement manufactured deposits a specific amount of captured carbon into the Carbon Bank. When Marley manufactures Edgemere 2.0 at its concrete facility in Glasgow, we use locally sourced Heidelberg cement to minimise costs and emissions associated with international transportation, while assigning the captured CO₂ savings from Norway’s Brevik plant to UK-produced cement. The equivalent portion of carbon savings can be withdrawn from the Carbon Bank using a mass balance approach.
This process allows each order of Edgemere 2.0 to come with complete traceability, documented through an Environmental Attribute Certificate (EAC), which is transferred directly to the end customer.
The result is that Edgemere 2.0 achieves a Global Warming Potential (GWP Fossil) of just 1.86 kg CO₂e per m² (from cradle to gate).
Building on the attributes of the existing Edgemere range, renowned for its slim profile and slate-like appearance, Edgemere 2.0 retains all the aesthetic benefits of traditional slate roofing while being lighter, more cost-effective and easier to install thanks to its interlocking design.
Available in Smooth Grey, Edgemere 2.0 provides a durable, stylish solution suitable for both new build projects and retrofitting to existing properties.
The launch of Edgemere 2.0 is not just a major advance for Marley but also a significant stride forward for the broader UK roofing and construction sectors.
By providing comprehensive, verifiable carbon documentation for every order, it actively supports the sector’s shift toward greener practices without requiring major changes in building specifications or architectural designs.
Key stakeholders now gain access to an environmentally advanced option through Edgemere 2.0. Its performance meets both current legislative requirements and future sustainability goals, offering a high-quality choice which is aligned with modern environmental expectations.
Marley’s innovative approach aims to fulfil the growing demand for measurable sustainability in building materials. In a market increasingly saturated with vague claims about eco-friendliness or carbon offsetting practices, the precise, data-backed carbon credentials of Edgemere 2.0 make it a stand-out product.
With Edgemere 2.0, Marley has further affirmed its commitment to equipping the industry for a lower-carbon future and addressing the rising call for verified sustainability from both professionals and regulatory bodies alike.
This approach is reinforced by clear evidence showcasing the product’s role in significantly lowering the carbon footprint of construction or renovation projects, all while maintaining essential elements such as functionality, visual appeal and overall efficiency in the building process.
