T/HPLIA 1303-2026 Greenhouse gas, product carbon footprint, quantification methods and requirements, wheat flour milling process

Scope

The increasingly frequent human activities have exacerbated global 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 actively participates in global climate governance and formulates a carbon reduction strategy based on its national conditions. In his important speech at the general debate of the 75th United Nations General Assembly, President Xi Jinping pointed out that China will increase its national contribution, adopt more effective policies and measures, strive to peak carbon dioxide emissions by 2030, and endeavor to achieve carbon neutrality by 2060. As a major agricultural country, China's greenhouse gas emissions from wheat processing have been on the rise. The wheat flour-making process can be divided into several stages, including wheat sampling and initial cleaning, wheat cleaning, wheat flour-making, and post-flour processing. The carbon emissions during the wheat flour-making process are the highest, with the carbon dioxide generated from energy consumption during the flour-making process contributing the most compared to other greenhouse gases. Secondly, the wheat cleaning process mainly generates carbon dioxide from logistics and transportation machinery during the wheat processing. The remaining part can be traced back to centralized storage and post-flour processing, involving electricity and energy consumption during storage and transportation, flour waste, and refrigerant leakage. In addition, the wheat flour-making process may also cause pollution to soil, atmosphere, and groundwater, disrupting the ecological balance, further exacerbating global warming. Extreme weather and ecological imbalance will in turn affect agricultural and livestock production, leading to an increase in crop pests and diseases, reduced grain yields, and a vicious c
