Research And Application Of Carbon Flow Diagram Analysis Method For Region And Enterprise

The environmental problems in the world are becoming more and more intense.Greenhouse gas is one of the most difficult problems.The simulation of Intergovernmental committee on climate change(IPCC)shows that the global temperature will rise 0.2~0.5 degrees every ten years in this century.If it is not checked,the danger of greenhouse gases to the earth will be no less than a nuclear war.The environment’s rapidly change has attracted the attention of the international community.From Kyoto Protocol to Paris agreement,more and more countries are involved in the work of saving the earth’s environment.As the largest developing country in the world,China has also made the promise that commitment to peak emissions of greenhouse gases in 2030.In this context,the paper draws up a method of drawing info diagrams of carbon and flow with reference to complex network analysis method,material flow analysis method and enterprise energy balance network drawing method.Carbon flow info diagrams and carbon flow sankey diagrams of Hubei and ceramics enterprises were drew.At the same time,the advantages and disadvantages in data expression between two kinds of carbon flow diagrams were analyzed,according to energy consumption data of Hubei Province based on the sub-sector energy balance table and a building ceramics production process.And then,the carbon emission intensity maps of different industries and sub-sectors in Hubei Province are drew,in hope that the carbon flow info diagrams and the regional carbon emission intensity info diagrams can provide relevant researchers with a tool to analyze the data characteristics and help them better analyze the direction of carbon flow in the enterprise or region system.They can offer the direction of energy conservation and emission reduction.The comparative of carbon flow info diagrams and carbon flow sankey diagrams that we drew show:the carbon flow info diagrams can well reflect the flow relationship of complex data,and clearly present the carbon flow data for each energy use links.However,its drawing process is a little bit complex and does not intuitively present data features.Carbon flow sankey diagrams intuitively reflects the characteristics of the data with the thickness of the lines,but the performance of complex data relationships will be messy and cannot reflect smaller proportion data.The info diagrams and the sankey diagrams are the same ways of expressing data and can present different characteristics of the data.If you want to intuitively express the maximum value of carbon emission data or a simple system for the flow process,you can use sankey diagrams;If you want to show each carbon flow data or the carbon flow process of the system are complex,carbon flow info diagrams are recommended.Finally,this paper draws a info diagrams of carbon emission intensity in Hubei Province.The carbon emission intensity info diagrams reflects the proportion of carbon emissions and carbon emissions of various industries and sectors in Hubei Province in 2014.It can provide convenience for the government research department to analyze the carbon emission intensity of the province and other provinces and cities,find out the province’s departments with greater carbon emission intensity and provide reference for the future adjustment of industrial structure etc.
