In recent years, more and more enterprises are required to disclose their sustainability reports, which means that sustainability plays an important role in the expansion and operation of global enterprises. Sustainability is also used to measure the development status and cultural orientation of the society. The furniture industry needs to be closely connected with the environment, economy, and society, so the theory of sustainable development is widely used in this industry. This paper chooses IKEA as the representative of the furniture enterprise to study and analyze its internal culture and definition of sustainable development, implementation strategy of the triple bottom line, existing defects, and development space, so as to help us better study the sustainable development of other industries.
