With the impact of human socio-economic development on the environment at this stage, the society has gradually realized that the relationship between socio-economic development and environment needs to be further coordinated for the batter symbiotic relationship. Green design is related to the common interests of all human being, it, as a design concept, has already been agreed with different sectors. However, due to the profitability of companies operating, the products marked with “green design” are advertised with a flourish of trumpets to stimulate consumption, It’s clear that building a green design evaluation system in the development process of green design is essential for ensuring the actual utility of “green products”. For this reason, it requires the pure motivation and the correct way to carry this out. The impure motivation will end up the “fake-green-design”, which has taken a sharp turn in the opposite direction subjectively. Furthermore, the incorrect methods will also lead to the “fake-green-design”. All these factors are the causes of deviation for the “green design”. This article aims to find a way to prevent this kind of deviation by constructing a green design evaluation system on the basis of exploring the root causes of the “false-green-design”.
