Abstract: As one of China's largest energy consumer, the carbon emissions from the iron and steel industry accounted for a significant portion of China's total greenhouse gas emissions. Considering CNKI as the retrieval source, this paper presents the development characteristics and trend of the researches on energy efficiency and carbon emissions of the iron and steel industry by a bibliometric analysis. The results reveal that:the scientific outcomes of this research field are increasing sharply since 2010. China Metallurgical News, China Steel Focus and Northeastern University are the famous origins or journals of these documents. Northeastern University, China Iron and Steel Association and China Metallurgical Industry Planning and Research Institute are outstanding research institutes in this research topic. The subject distribution suggested the researches on energy efficiency and carbon emissions of the iron and steel industry has developed into an interdisciplinary field, including metallurgical technology, industrial economy, management, environment. The related hotspots include cyclic economy, waste heat recovery and blast furnace, etc.
