China has already intended to peak carbon emission before 2030 and achieve carbon neutrality before 2060 in order to coordinate and protect the global climate. The accomplishment of this goal requires the reduction of dependence on fossil energies for energy consumption side and energy supply side. Glass industry plays a significant role in achieving the carbon neutrality target. The glass industry can release huge energy-saving potential through replacements of fuel and raw materials, improvement of energy efficiency, greater use of recycled glass, and development of thin glass. Various energy-saving glass products will show a more obvious energy-saving effect on the energy consumption side. On the energy supply side, glass is also a vital material to support the development of clean energy such as photovoltaics, wind power, and nuclear power. Therefore, glass materials will make a greater contribution to carbon neutrality of China.
