As an energy-intensive industry, China’s steel industry is one of the industries with the largest carbon emissions among the 31 categories of manufacturing industry, accounting for about 15% of the total carbon emissions in the country. In the past 10 years, China’s steel industry has been working towards low-carbon and green development. By 2021, 75% of steel energy comes directly or indirectly from coal, and steel carbon emissions account for 7% of global energy system emissions. The annual carbon emissions of China’s steel industry are 1.8 billion tons, accounting for 20% of industrial carbon emissions and 15% of the total national carbon emissions.
Compared with 2020, the steel output of key enterprises in 2021 will decrease by 0.23%, and the total energy consumption will decrease by 1.43%, indicating that the industry has made great progress in energy conservation; The comprehensive energy consumption per ton of steel in 2021 will be 550.43 kg of standard coal, 0.22 kg higher than that in 2020; The comparable energy consumption is 486.55 kg standard coal, 0.79% lower than that in 2020; China’s key steel ratio in 2021 is 0.8745, down 0.0131 from 2020, which is an important reason for the increase in comprehensive energy consumption per ton of steel.
