A Study On Accounting Carbon Footprint For One Chemical Enterprise

The social development and economic progress of one country is heavily dependent on chemical products.However,the diversification,complexity,and various types of industrial production have led to increasing pollutants.These pollutants have caused serious damage to people’s health and the natural ecosystem.Therefore,more countries have adopted various measures to control industrial emissions,such as the establishment of an effective cleaner production system,the control of production capacity,and the emissions limitation of those companies with intensive resource and energy consumption.In this regard,reducing carbon emissions from chemical companies is necessary since most chemical companies generate a large amount of carbon emissions.By describing the definition and classification of carbon footprint,this paper clarifies the basic theories of carbon footprint accounting methods at home and abroad,such as carbon footprint calculator,life cycle assessment(LCA),input-output analysis method,mixed life cycle assessment method and IPCC calculation method.At the same time,based on the whole life cycle theory,Shanghai Showa High-polymer Co.,Ltd.is taken as the actual research object,and carbon footprint,with the whole life cycle of raw material input,production process,product storage and waste disposal is calculated by using the calculation method guided by the "Guidelines for Accounting and Reporting of Greenhouse Gas Emissions from Chinese Chemical Manufacturing Enterprises(Trial Implementation)",through the data collection and listing,the key links and key data of Carbon Footprint Assessment in the production process of the enterprise are found out.Based on the evaluation results,the measures of energy saving and emission reduction for this type of chemical enterprises are discussed.In this paper,based on the calculation and analysis of carbon footprint,it is concluded that the main carbon emission sources of Shanghai Showa High-polymer Co.,Ltd.are the transportation of goods,the electricity consumption in the production process and the carbon emission from the use of calcium carbonate raw materials in the production process.This paper discusses these three carbon emission sources separately and puts forward measures to reduce carbon emissions.In the aspect of goods transportation,the carbon emissions from 1 ton of raw materials transported by road,rail and water are 44.09 kg,19.06 kg and 26.18 kg,respectively,which shows that the railway mode is the best.In terms of power consumption,the kneader and activated carbon equipment with high energy consumption were found out,and modification was proposed to reduce energy consumption.In the use of raw materials,it is proposed to reduce the use of calcium carbonate or replace other environmentally friendly raw materials to reduce carbon emissions from the source.
