中文摘要:

      我国提出二氧化碳排放力争于2030年前达到峰值，努力争取2060年前实现碳中和的“双碳”目标，在实现绿色转型的同时，“双碳”目标也给我国宏观经济发展、工业企业生产带来了巨大挑战。碳足迹评价工作是量化碳排放改善效果的技术基础，能够帮助企业开展积极有效的碳管理工作并提高产品绿色竞争力。文章基于全生命周期理论，建立了典型石化产品碳足迹核算方法学模型，并以某润滑脂为例进行了产品碳足迹的核算及分析。石化产品的碳足迹计算可以按流程分为原料带入、能源消耗、生产工艺、辅助材料和运输过程五个过程。通过研究发现，该润滑脂产品的碳足迹为1449.15kgCO₂/t，在其全生命周期碳足迹中原料带入排放占比最大，主要由产品采用多种化工原材料导致；其次是运输过程碳排放，主要由采用公路运输方式进行厂外产品运输导致；第三是能源消耗排放，其中大部分由于电力使用和天然气使用造成；辅助材料带入排放几乎可以忽略不计。文章通过分析认为使用绿色低碳原材料、合理优化运输布局、实施绿色电力替代和节能技术，能够有效降低产品碳足迹。

英文摘要:

      China has proposed to reach the peak of carbon dioxide emissions before 2030 and strive to achieve carbon neutrality before 2060. While achieving green transformation, the“dual carbon” goal has also brought great challenges to China’s macroeconomic development and industrial production. Carbon footprint evaluation is the technical basis for quantifying improvement effects of carbon emission, which can help enterprises to carry out active and effective carbon management and improve the green competitiveness of products. Based on the whole life cycle carbon footprint evaluation method, the article establishes a typical petrochemical product carbon footprint accounting model, and takes a certain type of grease as an example to carry out the product carbon footprint accounting and analysis. The carbon footprint calculation of petrochemical products is divided into five parts, including emissions from raw materials brought in, energy consumption, production process, auxiliary materials and transportation process. It is found that the carbon footprint of grease products is 1449.15kgCO₂/t, the proportion of emissions brought in by raw materials is the largest in its entire life cycle carbon footprint, mainly due to the use of multiple chemical raw materials in the product; Secondly, carbon emissions during transportation are mainly caused by the use of road transportation for off-site product transportation; The third is energy consumption emissions, most of which are caused by the use of electricity and natural gas; The emissions brought in by auxiliary materials can be almost negligible. Through the use of low-carbon raw materials, rational optimization of transportation layout, implementation of green power substitution and energy saving technology, the carbon footprint of the product can be effectively reduced.
