Abstract—At present, China's textile and garment industry is experiencing the transformation from high-energy consumption, low-added value, labor-intensive industrial model to low-energy consumption, high-added value, technology-intensive industrial model. This paper analyzes the environmental pollution and other challenges faced by China's textile and garment industry in the process of production and operation. Based on the analysis on the situation after joining SAC , we can find that there is a wide gap between China's textile and garment enterprises and other international enterprises in sustainable development. At the same time, the development of Chinese textile and garment enterprises is not balanced. Mainland enterprises have less investment in sustainable development than Hong Kong enterprises. Then this paper analyses the sustainability model of one of the most successful enterprises in Hong Kong, this model can be summarized into three levels: corporate culture level, strategic level and action level. Finally, this paper provides suggestions for the sustainable development of Chinese textile and garment enterprises from the government, enterprises and consumers aspects.
