Accounting Model of CO2 and its Application in Integrated Iron and Steel Enterprises
Integrated iron and steel enterprises is taken as the research object. Under the guidance of GHG Protocol standards for carbon emissions, the carbon dioxide accounting models on the process as a whole boundary are established, in which, the carbon emissions inventory is divided into three levels and the input data consists of CO2 emission coefficient and activity factor level data. The process model is the accounting model that the carbon emission is obtained through the balance of carbon input and carbon output outside the process boundary under the condition of considering the enterprise circulation. This article also researched one integrated iron and steel enterprise as a case. The results show that the model can quantify the emissions of different processes, provide basic value for the enterprise reduction, Identify major carbon source, identify the influence on carbon emissions by the changes of fuel structure, the structure of the process parameters and outsourcing by-product internal circulation. Therefore the model results can be used in the carbon emissions of enterprise internal assessment and decision-making.
