Energy-related GHG emission trajectories, features and driving forces of CAI are analyzed from the perspective of LCA.
CAI experienced a rapid growth of energy-related GHG emissions from 2004 to 2013.
Energy-scale effect is the main driving force for energy-related GHG emissions increase in CAI.
Construction and transportation-related activities account for more than 40% of the total embodied emissions.
Policy implications such as developing secondary aluminum industry, improving energy mix etc, are raised.
