Analysis of GHG Emission Verification of The Iron- steel Industry Case study of an iron-steel company in hebei province

The iron-steel industry is a resource and energy intensive industry and results to abundant GHG emissions because of a mass of fossil fuel consumption. In recent years, air quality in North China becomes worse and worse. In order to analyze the GHG emissions of the iron-steel industry, we made the survey in a typical iron-steel enterprise in Hebei province. According to the verification: CO2 emissions of coking, sintering, iron-making, steel-making and deep processing sectors respectively are 407.5, 1964.4, 1765.5, 124.0, 1279.0kt; CO2 emissions of production processing and electricity (including heating) are 562.0 and 211.0kt respectively and totally 12817.2kt for the whole production line. The uncertainty of the activity data is about ±3.54%, so it belongs to the high precision level. The research can help the iron-steel companies verify the GHG emissions in each process and find out emissions reduction potential.
