Abstract: Low carbonization is the key to sustainable development of ferrous metals industry.Using the bottom-up approach and related parameters, the paper estimated the carbon emissions from energy consumption of China's ferrous metals industry in 1994-2015, and made elastic analysis and factor decomposition.The results are as follows:total amount and intensity of carbon emissions are "inverted U", with growth rate of 8.76% and -5.02%.The smelting and pressing process, coke and blast furnace gas consumption are the main sources of carbon emissions.The decoupling elasticity between carbon emission and economic output is dominated by weak decoupling.Economic output is the biggest driver of carbon emissions, and energy structure is secondary.The effect of employment has been increasing since 2007.Energy intensity is the main emission reduction factor, while the industrial structure reduction function is weak.Emission factors have been enhanced since 2002.
