Abstract: Since, the world climate conference in Copenhagen 2009, low carbon has become the mainstream of the society. Low carbon gets trendy in the area of home electronics and the carbon emission calculation and evaluation draws attention from the home electronics enterprises that have already accumulated some knowledge on this issue. In this study, the carbon emission is assessed from the view of life cycle, consisting of both the direct emission and the indirect emission. Analysis of carbon footprint calculation results demonstrate that our method can help to make home electronics to be truly low carbon, conserve energy and reduce carbon emission, creating greater benefit for the enterprises and the society.
