October 14, 2020 is the 51st World Standards Day. In order to highlight the importance of standards in resource protection and green development, the International Organization for Standardization (ISO) and others have determined the theme of this year's World Standards Day as "Protecting the Planet with Standards ."

It is the responsibility of every enterprise to protect our homeland. ZTT has always contributed to the protection of the earth: designing and producing green products to provide customers with low-energy consumption service solutions; strictly managing the environmental impact of its own operations, striving to spread the concept of green environmental protection, and working with all others to protect our green homeland. In 2019, ZTT was recognized as a green factory by the Ministry of Industry and Information Technology.

ZTT is also actively promoting the external standardization of green achievements. It has led or participated in a number of national, industry and group standards related to green design, green manufacturing, energy saving, emission reduction and cascade utilization. At the same time, we are also intensifying our efforts to promote the international standardization of IEC and ITU-T.
