Glass is an integral part of modern life, but the environmental impact of glass production is significant, contributing approximately 86 million metric tons of carbon dioxide (CO₂) annually—about 0.3% of total global CO₂ emissions.¹ Addressing these emissions is critical for achieving the sustainability goals outlined by the United Nations.²

While 75–85% of the emissions in glass production are due to fuel combustion, 15–25% result from the decomposition of carbonate batch materials.¹ Soda-lime silicate (SLS) glass specifically is the primary contributor to these emissions as the most widely produced glass type.
