Estimating the macroeconomic costs of CO₂ emission reduction in China based on multi-objective programming

This paper estimates the macroeconomic costs of CO₂ emission reduction in China employing the input-output analysis with the multi-objective programming approach. The results show that the effect of reducing CO₂ emissions on China's economy is significant. Under the present conditions, the estimated macroeconomic costs of CO₂ emission reduction in 2010 for China are approximately 3,100-4,024 RMB t ^-1. The stronger the abatement actions, the higher the macroeconomic costs of per unit emission reduction would be. Excavation industry, oil industry, chemical industry, and metal smelting industry have high potential to abate their CO₂ emissions.
