炼化企业产品碳足迹核算研究进展
Research progress on product carbon footprint accounting in refining and chemical enterprises
尽管近期欧盟在碳边境调节机制(CBAM)的实施上有所缓和,但国际贸易局势复杂多变,我国炼化下游产品的出口仍面临巨大挑战。在此背景下,提升炼化企业的碳足迹核算能力,成为稳定出口态势的重要支撑。炼化行业工艺流程长、产品体系复杂,核算结果的可靠性高度依赖于模型、核算工具与数据库的本土化适配度。系统梳理了国内外炼化行业碳足迹核算标准制定的进展,概述了当前主流的碳足迹核算工具,并结合行业调研,总结了实际核算中在数据质量与可获得性、系统边界划分等方面存在的问题。通过对比国际大型炼化企业的实践经验,进一步探讨我国炼化企业在碳足迹核算体系建设方面可借鉴的发展方向。
Although the EU has recently eased its stance on the Carbon Border Adjustment Mechanism (CBAM),the international trade landscape remains highly volatile,and China’s downstream refining and petrochemical products continue to face substantial export challenges.Strengthening the carbon footprint accounting capabilities of domestic refining and petrochemical enterprises is a powerful guarantee for maintaining stable export performance.Given the long process chains and complex product portfolios in the refining and petrochemical sector,the reliability of accounting results depends heavily on the localization and adaptation of models,software,and databases to Chinese conditions.This paper reviews the recent progress in the development of carbon footprint accounting standards for the refining and petrochemical industry,introduces the current mainstream carbon footprint accounting tools,and based on industry surveys,identifies key practical challenges such as data quality and availability,system boundary delineation,and allocation issues.Based on this analysis,we compare the solutions adopted by leading global refining and petrochemical companies and explore directions that China’s refining and petrochemical enterprises can draw upon to advance their own carbon footprint accounting systems in the future.
