SZAP(SZ:000061) Yang Shi Wang·2026-01-11 06:32Core Viewpoint - The article highlights the emergence of "carbon footprint" as a new standard for green agricultural products, particularly in the citrus industry of Pujin County, Sichuan, where citrus products have received carbon label certification, leading to a price premium of 10% to 30% over similar products [1][11]. Group 1: Carbon Footprint and Certification - The carbon footprint of citrus products is calculated based on greenhouse gas emissions throughout their growth, processing, and transportation [1]. - Pujin County has initiated a "two replacements" project, replacing chemical fertilizers with organic fertilizers and traditional pesticides with green biological control methods [7][24]. - By the end of 2025, the organic fertilizer usage coverage is expected to reach 76.5%, and the green control coverage for major crops is projected to be 71% [9]. Group 2: Agricultural Practices and Innovations - The adoption of whole-plant covering with plastic film for citrus trees enhances fruit quality and protects against sudden temperature drops [6][19]. - The use of organic waste for soil improvement reduces chemical fertilizer usage and minimizes water pollution [15]. - Strict regulations are in place to limit the use of harmful pesticides and ensure traceability throughout the production process [17][20]. Group 3: Economic Impact and Market Opportunities - The citrus planting area in Pujin County is expected to reach 450,000 acres by the 2025-2026 harvest season, with an estimated production of 1.1 million tons and a direct output value exceeding 7.2 billion yuan [11]. - The carbon label has enabled Pujin citrus products to penetrate international markets, including Europe, Southeast Asia, and the United States [28]. - The annual output value of the citrus industry in Pujin County has surpassed 10 billion yuan, benefiting 260,000 local farmers [41]. Group 4: Future Developments and Database Initiatives - Scientists have developed a carbon footprint factor database for 27 types of agricultural products, which will expand to 50 core products by 2027 and cover all agricultural categories by 2035 [42][50]. - The database aims to monitor greenhouse gas emissions from various agricultural activities, including fertilizer and pesticide use, energy consumption during processing, and packaging emissions [44][48].
