The results of the LCA applied to copper and aluminum use in
the Chinese indoor air conditioner industry show that this industry
has an important environmental impact. This study determined
that (1) greenhouse gas emissions from the copper and aluminum
industries decreased from 2000 to 2009 and that substituting
aluminum for copper is possible; (2) copper and aluminum production
costs account for a higher proportion of the total costs and
are still increasing; (3) the smelting and processing stages are the
most important factors contributing to the environmental impact
of copper and aluminum production; and (4) with the growing
proportion of aluminum substitution for copper, the total costs of
the Chinese indoor air conditioner industry have shown an overall
decline. However, considering other possible changes, we suggest
that the proportion of aluminum substitution for copper should
remain at the 65%e75% level under the current conditions.
This work also presents some recommendations for reducing
the production costs and carbon sink forest costs of the Chinese
indoor air conditioner industry. Further improvements of the carbon
sink forest costs can be achieved by increasing energy efficiency,
limiting energy consumption, and eliminating electrolytic
aluminum. Developments in the technology regarding copper
replacement with aluminum and resource exploration are necessary
to improve production costs.
The development trends of aluminum substitution for copper in
the Chinese indoor air condition industry must be studied more
comprehensively, particularly the appropriate proportion of aluminum
replacing copper and the dynamic relationship between this
proportion and greenhouse gas emissions. This study provides general
information to help improve the environmental performance of
copper and aluminumuse in the Chinese indoor conditioner industry
