In 2023, China's crude steel production amount reached 1.019 billion tons, and the energy consumption of China's steel industry amount reached 561 million tons of coal. China's steel industry, with its dominant reliance on coal for energy and the primary use of blast furnaces and converters in production processes, as well as its massive output, has become the main field for achieving China's "carbon peaking" and "carbon neutrality" goals. Firstly, this article summarizes the current production status of the steel industry and the situation of carbon emissions in the steel industry. Secondly, it discusses the dual-carbon policies based on the national and steel industry levels and outlines the future directions for China's steel industry. Subsequently, it analyzes the current state of research and application of mature and emerging low-carbon technology in China's steel industry and details the low-carbon plans of China's steel companies using the low-carbon technology roadmaps of two representative steel companies as examples. Finally, the article gives policy suggestions for the further carbon reduction of China's steel industry. The purpose of this paper is to show the efforts and contributions of China's steel industry to the early realization of its "carbon peaking" and "carbon neutrality" goals. [ABSTRACT FROM AUTHOR]

Achieving carbon peaking and carbon neutrality is an intrinsic requirement for sustainable development. The industrial structure primarily characterized by the chemical and energy industries poses a hindrance to the attainment of carbon peaking and carbon neutrality goals in the provinces of the Yellow River Basin of China. Predicting the time of carbon peaking and carbon neutrality and exploring the pathways of carbon peaking and carbon neutrality is an urgent issue for the government to address. The STIRPAT and InVEST models were used for the carbon emissions and carbon sequestration estimation in the nine provinces and regions of the Yellow River Basin from 2010 to 2060. The results show that the study area will realize carbon peaking in 2030 under the baseline scenario, with the carbon emission of 4146 million tons. Under the high-emission scenario, the study area will realize carbon peaking in 2035, with the carbon emission of 4372 million tons. Under the low-carbon energy-saving scenario, the study area will realize carbon peaking in 2025, with the carbon emission of 3909 million tons. The entire study area cannot achieve carbon neutrality in 2060 under the three scenarios. Under the baseline and high-emission scenarios, only Qinghai and Sichuan can realize carbon neutrality by 2060, and under the low-carbon energy-saving scenario, Sichuan, Qinghai, Shaanxi, and Gansu will achieve carbon neutrality on time. This research indicates that attaining carbon peaking and carbon neutrality can be accomplished by implementing strategies such as encouraging the growth of clean energy, managing energy usage, refining the industrial structure, and strengthening the ecosystem's carbon sink.

The carbon emissions of the power industry account for over 50% of China's total carbon emissions, so achieving carbon peak and carbon neutrality in the power sector is crucial. This study aims to simulate the impacts of three energy policies—carbon constraints, the development of a high proportion of renewable energy, and carbon trading—on China's energy transition, economic development, and the power sector's energy mix. Through the construction of a dynamic computable general equilibrium (CGE) model for China and its integration with the SWITCH-China electricity model, the impact of diverse energy policies on China's energy transition, economic progress, and the power mix within the electricity industry has been simulated. The integration of the SWITCH-China model can address the limitations of the CGE model in providing a detailed understanding of the specific intricacies of the electricity sector. The results indicate that increasing the stringency of carbon restrictions compels a reduction in fossil energy use, controlling the output of coal-fired power units, and thereby reducing carbon emissions. The development of a high proportion of renewable energy enhances the cleanliness of the power sector's generation structure, further promoting the national energy transition. Implementing a carbon trading policy, where the entire industry shares the burden of carbon reduction costs, can effectively mitigate the economic losses of the power sector. Finally, the policies to further enhance the implementation of carbon trading policies, strengthen effective governmental regulation, and escalate the deployment of renewable energy sources are recommended.
