基于国际标准的输电线路铁塔生产企业温室气体排放量化及减排对策研究OA

The production enterprises of transmission line towers are widely distributed in China,and towers are important infrastructure for the power grid and power system,conducting research on the quantification and reduction strategies of greenhouse gas emissions in the production and manufacturing process can help the tower industry scientifically set carbon reduction goals in the context of carbon peak and carbon neutrality,as well as the development of new power systems,and promote the industry's green and low-carbon development.Based on the international standards for quantifying greenhouse gas emissions and combined with the actual production and operation data of a large transmission line tower manufacturing enterprise,a case study analysis is conducted to quantify the greenhouse gas emissions of Scope 1,Scope 2,and Scope 3 of the enterprise in 2023 using Intergovernmental Panel on Climate Change(IPCC)methodology and the internationally recognized Ecoinvest database.The results show that at the organizational level,the total greenhouse gas emissions of the enterprise are 165 942.36 t of CO2e,with the greenhouse gas emissions from the metal raw material acquisition process accounting for a relatively high proportion,reaching 92.76%.Based on emission data and the actual situation of enterprises,the targeted greenhouse gas emission reduction measures are proposed,and the future research directions are finally looked forward.Overall,it is necessary to establish a green supply chain system,improve the recycling and utilization rate of metal raw materials,use clean energy,replace welding protection gas,and use efficient anti-corrosion processes.The research results will help standardize the measurement of greenhouse gas emissions in transmission line tower enterprises,improve the management capability of greenhouse gas emissions in tower enterprises,break down green trade barriers,and promote the green and low-carbon development of the industry.
