Saint-Gobain Glass UK & Ireland says it has taken a significant step forward in lower-carbon flat glass production. At its Eggborough plant, near Goole, Planiclear is now reported to achieve 7.22 kgCO₂e/m² for 4mm glass.

The new Environmental Product Declaration (EPD) reflects Saint-Gobain Glass UK & Ireland’s regular, day-to-day production and is not based on a trial or short-term campaign.

The new declaration shows a reduction of more than 34% compared with the previous EPD. According to Saint-Gobain Glass, this strengthens Planiclear as a practical choice for lowering embodied carbon, while maintaining the same quality, availability, and performance.

Decarbonisation roadmap
This progress is driven by Saint-Gobain Glass UK’s decarbonisation roadmap and its Glass Forever circular economy approach to flat glass recycling. Together, they focus on three key areas: increasing circularity, reducing reliance on virgin raw materials, and improving renewable energy use and process efficiency.

Producing around 13 miles of flat glass daily, the Eggborough site is embedding lower-carbon manufacturing at scale and is making lower carbon specification simpler for the construction and retrofit markets.

The EPD is third-party verified and positions Planiclear among the lowest embodied carbon standard float glass products manufactured in the UK. It provides robust data for planning, Environmental, Social, and Governance (ESG) reporting, and procurement decisions.

Critically, this applies to standard Planiclear, supporting lower embodied carbon at sealed unit level with no added cost and no change to product performance.

New EPDs available
New EPDs are now available for all Planiclear thicknesses and Sapphire Blue. UK coated and laminated products will also benefit from this lower embodied carbon substrate, with supporting EPDs expected to be validated in the second half of 2026.
