“…The emission inventory of pollutants and CO 2 was established based on the bottom-up emission factor method. The total emissions of SO 2 , NO x , CO, PM 10 , PM 2.5 , VOCs, NH 3 and CO 2 , in the 13 industrial parks in 2017 were 43,40,351,19,7,18, 2 kt and 36 Mt, respectively. SO 2 and NO x mainly come from power plants, accounting for 41 and 49% of the total emissions, respectively, which may be due mainly to the coal-fired boilers and large installed capacity of power generation.…”

“…It can be seen that Anyang Steel Park is the major contributor of SO 2 , NO x , CO, PM 2.5 , VOCs and CO 2 , with emissions of 17, 13, 306, 2, 10 kt and 11 Mt, respectively. Anyang Steel Park is one of the most important steel production bases in Henan Province, and the main fuel types of industry boilers are blast furnace gas and coke oven gas [43]. Furthermore, there are a lack of dust removal measures and desulphurization processes in Anyang Park.…”

Although central to the promotion of regional economic development, industrial parks discharge large quantities of air pollutants and CO2, counter to the goals of air quality improvement and CO2 reductions in China. In this study, 13 industrial parks in seven cities in Henan Province were chosen to evaluate their emission of air pollutants and CO2 in 2017, their reduction potential under different green measures, and their air quality improvements under a Green Upgrade scenario. The results show that: (1) The total emissions of SO2, NOx, CO, PM10, PM2.5, VOCs and CO2 in the 13 industrial parks were 43, 39, 351, 19, 7, 18, 2 kt and 36 Mt, and would decrease by 72, 56, 19, 30, 26, 77 and 30%, respectively, under the Green Upgrade scenario. (2) The industrial process was the major source of CO, PM2.5, VOCs and NH3, whereas power plants were the largest source of SO2 and NOx, and they would be reduced by 93, 59, 94, 91, 23 and 28%, respectively, under the Green Upgrade scenario. (3) The terminal energy use sector (including industrial boilers and industrial process sources) was the main source of CO2, accounting for 75% of total CO2 emissions, and would be reduced by 76% under the Green Upgrade scenario. (4) WRF-CMAQ simulation results show that, under the Green Upgrade scenario, the concentration of PM2.5 in a transmission channel city would be improved by 1–36 μg/m3, with an annual average value of 9 μg/m3. Our results demonstrate the significant effect of the synergistic reduction in air pollutants and CO2 emissions using Green Technologies in industrial parks and the subsequent improvement in regional air quality.

“…In a word, there is still considerable carbon reduction potential for energy efficiency improvement in China's ISI. The energy efficiency improvement of ISI has been analyzed in most previous studies [9,10,23,68]. To sum it up, three key ways can be identified for the energy efficiency improvement in China's ISI:…”

“…However, the long-term low-carbon development pathway of China's ISI is still unclear. In recent years, policies related to China's ISI have mostly focused on energy conservation [9,10] and ultra-low emissions of pollutants [11][12][13], which has indeed brought a positive impact on the reduction of energy consumption and pollutant emissions. Under China's commitment to carbon neutrality by 2060, low-carbon development will be the new focus and the urgent target for China's ISI.…”

The low-carbon development of China’s iron and steel industry (ISI) is important but challenging work for the attainment of China’s carbon neutrality by 2060. However, most previous studies related to the low-carbon development of China’s ISI are fragmented from different views such as production-side mitigation, demand-side mitigation, or mitigation technologies. Additionally, there is still a lack of a comprehensive overview of the long-term pathway to the low-carbon development of China’s ISI. To respond to this gap and to contribute to better guide policymaking in China, this paper conducted a timely and comprehensive review following the technology roadmap framework covering the status quo, future vision, and key actions of the low-carbon development of the world and China’s ISI. First, this paper provides an overview of the technology roadmap of low-carbon development around the main steel production countries in the world. Second, the potential for key decarbonization actions available for China’s ISI are evaluated in detail. Third, policy and research recommendations are put forward for the future low-carbon development of China’s ISI. Through this comprehensive review, four key actions can be applied to the low-carbon development of China’s ISI: improving energy efficiency, shifting to Scrap/EAF route, promoting material efficiency strategy, and deploying radical innovation technologies.

“…Gao et al [22] established the evaluation framework model of water and energy consumption in the steel industry, and quantitatively evaluated the energy-and water-saving situation of traditional and emerging technologies. Long et al [23] comprehensively analyzed various factors affecting energy conservation and emission reduction potential, and quantitatively evaluated energy intensity, greenhouse gas emission intensity and other indicators under five scenarios. Griffin et al [24] conducted a comprehensive analysis of energy saving technologies used in the U.K. steel industry and pointed out that existing technologies can reduce a significant proportion of process energy loss, but that there are a number of non-technological barriers.…”

The effect of the traditional energy saving mode on process engineering is decreasing, so the idea of system energy saving is developing vigorously. This paper summarizes the existing studies on energy saving from three aspects—energy saving technology, energy management, comprehensive evaluation or analysis—and clearly finds that related studies on energy saving have been gradually promoted to promote the development of system energy saving in the whole process engineering process. Among them, the calculation of energy saving brought by energy saving technology is a difficult point in the research. This paper proposes a novel calculation method of energy saving by taking the iron and steel production process (ISPP) as an example. According to the actual data provided by a steel plant in China, the calculation method is validated effectively.
