The current study aims to (1) describe, with the aid of the LCA
method, the environmental impact, particularly greenhouse gases,
of copper and aluminum production in the Chinese indoor air
conditioner industry and (2) propose a comprehensive strategy for
the synergistic control of carbon footprint when copper is replaced
with aluminum. Section 2 describes the systematic methodology
for this study, comprising the pretreatment of the original data and
the application of the LCA method. Section 3 shows the accounting
process and the results on the carbon footprint of copper and
