| China has proposed to reach the peak of carbon dioxide emissions by 2030 and strive to achieve the "double carbon" goal of carbon neutrality by 2060, and industrial enterprises are facing great pressure to adjust while achieving green transformation. Carbon footprint evaluation is the technical basis for quantifying carbon emission improvement effects and industrial policies, and can help enterprises to carry out active and effective carbon management work. 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. |
