The NSG Group works to reduce environmental impact at all stages of glass production and processing.

The NSG Group’s operations in Japan cause the emission of approximately 760,000 tons of CO₂. Of these operations, the process that has the greatest impact on the environment is the melting of the raw materials using heat (between 1,600°C and 1,700°C) from the combustion of fuel oil. In contrast, other processes, such as cutting and forming, do not require high temperatures and have little environmental impact. The melting of raw materials is indispensable in the manufacture of glass and requires the use of a certain amount of energy. The NSG Group is taking wide-ranging measures to reduce CO₂ emissions during the manufacturing process.

In Japan, the CO₂ reductions accruing from the use of NSG Group insulating glass products are calculated at 580,000 tons (NSG Group study). The study also shows that NSG Group achieves an approximate 80% (760,000 tons) in CO₂ emissions during glass manufacturing. At NSG Group, popularizing the shielding effect and superior insulating properties of double-glazed glass and vacuum glass contributes to the reduction of energy used for heating and cooling and thus of CO₂ emissions.
