Marley launches Edgemere 2.0, the first UK roof tile to use carbon-capture cement technology

In a first for UK roofing, Edgemere 2.0 combines Marley’s familiar concrete roof tile specification with carbon-capture cement technology and Carbon Bank evidence supplied for every order.
The carbon reduction story behind Edgemere 2.0* begins with the cement. CO₂ from cement production is captured at source, before it enters the atmosphere, and permanently stored beneath the seabed. The carbon reduction is then recorded in the publicly available Carbon Bank, which allocates captured and stored CO₂ reductions to specific Edgemere 2.0 orders, with full end-to-end traceability through an Environmental Attribute Certificate (EAC).
The launch responds to a market in which embodied-carbon evidence is moving from optional to expected. For the public sector and increasingly housing providers, product-level carbon evidence is becoming part of the specification process.
Sustainability leads, along with quantity surveyors and architects, are frequently asked to produce verifiable, product-level carbon evidence and do so without redrawing details or rewriting specifications.
Edgemere 2.0 expands the Edgemere range by offering a low carbon option with a Global Warming Potential (GWP Fossil) of just 1.86kg CO2e per m² from cradle to gate, whilst retaining the familiar thin leading edge, technical performance and dimensions of Edgemere together with a Green Guide A+ rating and BES 6001 Excellent certification.
The change is behind the tile: in the cement production process and the addition of verified, order-specific documentation. The Carbon Bank allocates reductions from actual captured and stored CO₂, to specific Edgemere 2.0 orders, with ownership of the EAC transferring to the final customer.
“Edgemere 2.0 is a significant step forward for Marley and for the roofing industry,” said Stuart Nicholson, Managing Director at Marley. “By introducing the UK’s first concrete roof tile to use carbon-capture cement technology, we’re supporting the industry’s transition to lower-carbon construction, with a documented carbon-evidence trail supplied for every Edgemere 2.0 order.”
Edgemere 2.0 is available in Smooth Grey. For more information, or to discuss your next project with one of our specification experts, visit www.marley.co.uk/Edgemere2
About the carbon evidence and end-to-end traceability
*Edgemere 2.0 is supported by Heidelberg Materials’ evoZero® carbon captured near-zero cement, enabled through the first carbon capture facility at its cement works in Brevik, Norway. To avoid the transport emissions that would be incurred by shipping from Brevik, Edgemere 2.0 CO₂ reduction can be transferred and attributed to locally sourced Heidelberg Materials cement.
A Carbon Bank withdrawal is made to reduce the corresponding Global Warming Potential (GWP Fossil) of the locally produced UK cement to zero. The carbon reduction is recorded in Heidelberg Materials’ publicly available Carbon Bank, which allocates captured and stored CO₂ reductions to each specific Edgemere 2.0 order, with full end-to-end traceability through an Environmental Attribute Certificate (EAC).
