氮肥协会：推进合成氨/尿素碳足迹量化国标制定

Core Viewpoint - The establishment of a national standard for carbon footprint quantification in the nitrogen fertilizer industry is crucial for reducing carbon emissions, particularly for synthetic ammonia and urea products, as China transitions from energy consumption control to carbon emission control [1][2] Group 1: Carbon Emission Data - The carbon dioxide emission per ton of synthetic ammonia produced from coal in 2024 is projected to be 4.2 tons, with a total annual emission of approximately 234 million tons [1] - The carbon dioxide emission per ton of urea (including the raw material synthetic ammonia) is estimated at 2.91 tons, leading to an annual emission of about 147 million tons [1] Group 2: Industry Standards and Framework - The nitrogen fertilizer association is developing a standard based on the national standard GB/T 24067-2024, which includes a comprehensive framework for carbon footprint quantification [2] - The main technical content of the standard consists of over ten sections, including standard scope, normative references, terminology and definitions, quantification objectives, and carbon footprint reporting [2] Group 3: Industry Transition and Focus - The nitrogen fertilizer industry faces urgent carbon reduction tasks as it is one of the sectors with significant carbon emissions [1] - By 2025, the steel, cement, and aluminum smelting industries will be included in the national carbon market, with petrochemicals and chemicals being the next focus for research [1]
