    Grayson ISO 14068 carbon neutrality: key embodied carbon notes for contractors

    First reported on The Construction Index

    30 Second Briefing

    Grayson has secured ISO 14068 carbon neutrality certification, moving from PAS 2060 to the more demanding international standard that requires quantified emission reductions and independently verified offsets. The company has invested in on-site solar generation, battery storage and lower-carbon logistics, and developed site products such as the recycled aluminium G Board mortar board, designed to replace multiple timber boards over a bricklayer’s career and remain fully recyclable. Building on its earlier Zero Waste to Landfill status, Grayson is among the first UK construction suppliers to meet ISO 14068, giving contractors stronger assurance on embodied carbon claims.

    Technical Brief

    • ISO 14068 requires quantified emission measurement, demonstrable reductions, then offsetting only the verified residual balance.
    • Certification demands third‑party verification of both reduction pathways and offset quality, not self-declared claims.
    • Framework replaces PAS 2060, introducing a more prescriptive international methodology for defining and proving carbon neutrality.
    • G Board mortar board uses recycled aluminium, engineered for full recyclability at end of service life.
    • Product design intent is single-board use over a bricklayer’s full career, displacing multiple timber units.

    Our Take

    Auditel’s role in this UK certification context indicates that third‑party verification is becoming normalised for construction supply-chain emissions data, raising the bar for competitors that still rely on self-declared ‘green’ credentials.

    Paladin rare earth recycling expansion: supply-chain takeaways for engineers

    Rare earth recycler Paladin EnviroTech is investing over US$5 million to expand its Ohio recovery facility from 40 to 150 tonnes per year by Q3 next year, targeting end-of-life hard drives, EV motors, generators, MRI machines and wind turbines containing neodymium, praseodymium, terbium and dysprosium (up to ~16% Dy in MRI magnets). Working with Western Digital and Critical Materials Recycling, Paladin uses a non-acidic selective leaching process achieving 97–98% rare earth recovery and about 90% total value recovery, feeding mixed rare earth oxides back into Western magnet supply chains.

    Breedon’s new CEO from 2027: strategic implications for materials project teams

    Breedon has appointed current chief financial officer James Brotherton as its next CEO from 1 January 2027, succeeding Rob Wood after a 12-year tenure with the construction materials group. Brotherton has been CFO since 2021 and co-developed Breedon’s “expand and improve” strategy, which underpinned its expansion into the US market and transfer to the London Stock Exchange’s main market. Wood, who became CEO in 2021, will step down from the board at end-2026 but remain an employee to support the leadership transition until September 2027.

    Chryso–Ecocem low‑carbon cement system: mix design notes for concrete engineers

    Saint-Gobain’s Chryso and Ecocem have launched a combined low‑carbon system pairing Ecocem ACT cement, which cuts cement emissions by up to 70%, with Chryso’s new superplasticiser EnviroMix 3150 ACT, formulated for this binder chemistry. The admixture–cement combination enables concrete mix designs achieving over 50% carbon footprint reduction, meeting GWR5 and above, while maintaining high flowability, low viscosity at low water–cement ratios, and workability retention beyond 90 minutes without segregation. On the former John Lewis HQ refurbishment in London, around 1,300 m³ of C20/25 and C30/37 ACT concrete is being pumped using EnviroMix 3150 ACT to validate performance under site conditions.
