Abstract: In this paper, we evaluated the effects of consumer's behavioural changes on usage and disposal of home appliances. With the model to estimate the product circulation, first we conducted the sensitivity analysis with the six parameters, namely urbanisation, household size, Gini coefficient, product lifetime and selection rate of used product and high energy efficiency product. Then, secondly we evaluated CO 2 emission and e-waste generation from four consumers' different behavioural patterns, which are named as 'Business As Usual' (BAU), 'Rapid Cycling' (RC), 'Chain of Users' (CU) and 'Quality and Wisdom' (QW). As a result, the QW scenario was the best lifestyle in both criteria. Further, RC scenario had an advantage on the reduction in e-waste generation in one hand, but CU scenario reduced more CO 2 emission. During the transition era of China from materially poor to rich, it could be one of the solutions to utilise energy-efficient second-hand product to improve the living standards of the poor and replace technologically inferior product stocks in poor households.
