As the building sector continues to be one of the primary contributors to resource consumption and carbon emissions, we, as a glass manufacturer, recognize our responsibility to address this issue.
At Saint-Gobain Glass, we strive to build better for the planet, and we firmly believe that through innovation, we can create glass solutions, such as low-carbon glass, that are not only highly efficient but also have reduced environmental impacts.
What is low-carbon glass?
Given the current environmental concerns, low-carbon glass is a type of glass specifically designed to have reduced embodied carbon. Integrating low-carbon glass into buildings’ glazed surfaces can effectively contribute to reducing the carbon emissions of buildings over their entire lifecycle.
The production of this distinctive glass range incorporates a variety of good practices, such as the use of renewable energies along with a higher percentage of recycled glass to help reduce the carbon emissions and resource consumption related to glass manufacturing.
Furthermore, by addressing the embodied carbon of buildings, low-carbon glass can support the objective of achieving net zero-carbon buildings.
Leading Low-Carbon Glass Production on a Global Scale
As the need for more sustainable construction continues to grow, we have taken it upon ourselves to develop sustainable glass for buildings. We have been continuously working on improving our glass solutions to foster sustainability and performance in the construction industry.
In 2022, we took a significant step further by introducing the first low-carbon offer on the glass market and we plan to continue pushing for more sustainable solutions to offer a complete range for all the markets and drive positive change.
ORAÉ®: the first low-carbon glass on the market
In July 2022, we proudly announced a significant breakthrough by revealing the launch of a new glass substrate: ORAÉ® is the first low-carbon glass to enter the market, offering a significant reduction in embodied carbon. The recently introduced range of glass has set a new standard at 6.64kg CO2 eq./m² according to its verified EPD (from Cradle-to-Grave for a 4mm substrate). This figure represents a reduction of 42% compared to Saint-Gobain Glass European baseline for clear glass.
ORAÉ® is the result of tremendous R&D efforts, successful production trials and the in-depth knowledge of Saint-Gobain Glass’s industrial teams. It has been made possible to attain this low carbon footprint thanks to the usage of renewable electricity and a high percentage of recycled glass.
This new substrate was integrated into our portfolio of glass solutions by combining it with our solar control range: COOL-LITE® XTREME to ensure the reduction of both operational carbon emissions of buildings’ façades (related to their cooling, heating, and lighting needs) but also their embodied carbon emissions.
The first low-carbon production in India
Continuing in the same steps towards decarbonising the glass industry, Saint-Gobain India announced the launch of the first production of low-carbon glass in India with a carbon footprint reduced by up to 40% over its whole life cycle, compared to the current product range.
These environmental feats were made possible by using electricity generated from renewable energy sources, as well as the use of two-thirds of recycled glass. The production data will be logged and used to create a validated EPD, which should be released later this year and attest to the large reduction in carbon footprint. This accomplishment by Saint-Gobain India showcases the steadfast commitment to the Group's objective of achieving carbon neutrality by 2050.
