T/HPLIA 1302-2026 Greenhouse Gas Product Carbon Footprint Quantification Methods and Requirements for PVC Structural Foam Materials

Scope

The increasingly frequent human activities have exacerbated global climate warming, making the conflict between human development and the environment increasingly intense. In recent years, "peaking carbon emissions" and "carbon neutrality" have become the focus of public attention. As a responsible major power in the world, China has actively participated in global climate governance and formulated a carbon reduction strategy based on its national conditions. In his important speech at the general debate of the 75th session of the United Nations General Assembly, President Xi Jinping pointed out that China will increase its national contributions, adopt more effective policies and measures, strive to peak carbon dioxide emissions by 2030, and work hard to achieve carbon neutrality by 2060. As a major industrial manufacturing country, China's production and application scale of PVC composite foam materials continue to expand, and market demand continues to grow. The preparation process of PVC composite foam materials can generally be divided into raw material pretreatment, mixing and plasticization, foaming molding, post-processing and cutting, etc. Among them, the carbon emissions in the foaming molding process are the highest, mainly from the heat consumption in this process and the carbon dioxide produced by the decomposition of chemical foaming agents; followed by the mixing and plasticization process, mainly from the indirect emissions corresponding to the power consumption of mixing equipment and extruders; the remaining emissions can be traced back to the raw material transportation, product post-processing and packaging stages, involving fuel consumption caused by logistics transportation, energy consumption of processing scrap materials, and refrigerant leakage, etc. In addition, during the preparation process of PVC composite foam materials, there may also be potential impacts on the atmosphere, soil and water environment due to volatile organic compound
