Introduction Engels (2009) using the full life cycle cost method such as printer shows that carbon costs include the purchase of raw materials and transportation process,production process,labor and energy consumption,waste treatment process and products eventually recycled carbon emissions from several parts.Xiaodong Shang(2013) to resources such as value stream into perspective,constructs the enterprise cost of carbon emissions model,analyze the enterprise cost of carbon emissions,proposes the research trend of carbon cost,makes the enterprise management decision can consult carbon cost accounting information.
It’s no longer free for carbon emissions,enterprises should set up the cost control of system consciousness and enhance a carbon emissions cost control for the following several points:At first,enterprises should consider investment in low-carbon technologies to identify,control and prevent carbon emissions in the production process.In addition,enterprises should be ready to adapt to a series of things such as carbon emissions trading,their decisions and actions require that the accounting can reflect the carbon emissions action.What’s more,enterprises should improve the industrial added value,reduce resource consumption and reduce carbon emissions by increasing the input of science and technology and other means.
