中国制造业碳排放问题分析与减排对策建议

How to achieve the goal of building a modern socialist country in an all-round way and achieving carbon neutrality by 2060 is a necessary question for the future development of manufacturing industry. Pushing energy intensive and highly polluting manufacturing enterprises to "green manufacture" is a key step to achieve the goal of peak carbon dioxide emission and carbon neutrality. The current situation of carbon emission in manufacturing industry from accounting methods, macro indicators, industry distribution and energy structure were summarized and analyzed in this study. And then, the common carbon emission reduction countermeasures and low-carbon technology in key industries of manufacturing industry were introduced. Finally, the relevant commercial applications were listed and the technical development bottlenecks were explained. Common mitigation strategies for manufacturing were source reduction, clean energy using, carbon capture, utilization and storage, and the industrial internet. Low-carbon production technology in the key industries mainly included direct reduction of hydrogen to produce iron and steel, hydrogenation of carbon dioxide to methanol, biomass to bio-oil, etc. Iron and steel, chemical industry, building materials, petrochemical and coking, non-ferrous metal smelting as the important parts for manufacture, should contribute to the goal of carbon neutrality by choosing mitigation strategies adapted to their own production processes.
