Saint-Gobain Glass UK & Ireland has introduced a new benchmark for lower-carbon flat glass production, with its Eggborough plant near Goole achieving 7.22 kgCO₂e/m² for 4 mm PLANICLEAR®, according to a newly published Environmental Product Declaration (EPD).
The declaration reflects the company’s normal manufacturing process rather than a limited production run or pilot project. PLANICLEAR® is produced and supplied under these conditions as part of everyday operations, marking a shift from one-off demonstrations to standard manufacturing.
The updated EPD records a reduction of more than 34% compared with the previous declaration. Saint-Gobain Glass UK & Ireland said the change allows customers to specify a lower embodied carbon product without altering quality, performance, availability, or cost.
The reduction forms part of the company’s wider decarbonisation roadmap and its Glass Forever approach to flat glass recycling. The strategy centres on increasing circularity, reducing the use of virgin raw materials, improving renewable energy use, and raising process efficiency.
The Eggborough facility produces around 13 miles of flat glass each day, placing lower-carbon manufacturing within its regular production output. By lowering the footprint of its core glass product, the company aims to make lower embodied carbon specification more straightforward for construction and retrofit projects.
The EPD has been verified by an independent third party and, according to Saint-Gobain Glass UK & Ireland, places PLANICLEAR® among the lowest embodied carbon standard float glass products manufactured in the UK. The declaration is intended to support project planning, Environmental, Social, and Governance (ESG) reporting, and procurement decisions by providing independently verified environmental data.
The company said the reduced embodied carbon applies to standard PLANICLEAR®, allowing sealed glass units to benefit without additional cost or changes to product performance.
New EPDs are now available across the full PLANICLEAR® thickness range as well as Sapphire Blue glass. Saint-Gobain Glass UK & Ireland added that coated and laminated products manufactured in the UK will also use the lower embodied carbon substrate, with supporting EPDs expected to be validated during the second half of 2026.
Why This Matters: This announcement marks an important shift for the UK flat glass market because the lower embodied carbon figures apply to standard, everyday production rather than a limited manufacturing campaign. That distinction gives architects, fabricators, contractors and specifiers greater confidence when selecting products for projects with demanding carbon targets. With increasing pressure from developers and public sector clients to reduce whole-life carbon, independently verified EPDs are becoming an essential procurement requirement. By lowering embodied carbon without changing performance, availability or price, Saint-Gobain Glass UK has raised expectations across the market and is likely to increase competitive pressure on other UK float glass manufacturers.
