A third-party verified confirmation of ORAÉ®’s environmental performance

Thanks to a verified EPD*, ORAÉ® - the very first low carbon glass on the market launched last September by Saint-Gobain - is now confirmed as the glass with the world’s lowest carbon footprint, setting a new standard at 6.64kg CO2 eq./m² (from Cradle to Grave for a 4mm substrate).

This is a reduction of 42% compared to Saint-Gobain Glass European baseline for clear glass thanks to a remarkably high amount of recycled content and with no compromise on the technical, quality or aesthetic performances.

Regarding the French market, the environmental and sanitary declaration called FDES has also been validated at 6.64kg CO2 eq./m² and is already available on the INIES data base.

*An EPD is an Environmental Product Declaration, a third-party verified document that indicates the environmental impact of a product during its life cycle.

As a sign of the market's enthusiasm for this major innovation, several major real estate partners have chosen Saint-Gobain Glass to reduce the carbon footprint of some of their pioneer projects.

The latest one to have chosen COOL-LITE® XTREME ORAÉ® for a new project being the Swedish developer NCC for the Habitat 7 building located in Gothenburg (Sweden), in collaboration with the facade maker Fasadglas.

This attests to the key role that ORAÉ® plays towards a more sustainable industry and in accelerating the development of the circular and low carbon economy.

Thanks to the detailed environmental data available, ORAÉ® is now integrated in Calumen®, Saint-Gobain's all-in-one glazing digital configuration tool. Building professionals, regardless of their level of expertise, can now evaluate the impact of ORAÉ® on the carbon footprint of their architectural projects.
