In 1893, Sir James Dewar, a Scottish scientist invented the vacuum flask in the course of extensive research into liquefaction of hydrogen and established the two fundamental principles of vacuum insulation: the use of high vacuum to insulate gas conduction and convection heat transfer, and the use of high reflective coating to reduce radiation heat transfer.
In 1994, NSG of Japan purchased the patent rights from the University of Sydney and officially launched the vacuum glazing products in 1997.
China started to develop vacuum glass in 1998. By 2008, it has established the world’s first industry standard for vacuum glazing, JC-T1079-2008.
In 2015, the United Nations Framework Convention on Climate Change (UNFCCC) passed the Paris Agreement. Nearly 200 countries around the world agreed to strengthen cooperation in dealing with the threat of climate change. The aim of the agreement is to hold the increase in the global average temperature to well below 2 °C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels. In 2015, China submitted the Enhanced Actions on Climate Change: China's Intended Nationally Determined Contributions to the Secretariat of UNFCCC. According to the document, China has determined its actions by 2030 to lower carbon dioxide emissions per unit of GDP by 60% to 65% from the 2005 level.
