Abstract：Take the example of pulp and paper companies,advantages and disadvantages of several commonly used accounting methods for the emission performance value of chemical oxygen demand (COD) were compared.Methods such as correlation analysis, linear regression, and weighted average were proposed as potential tools for the calculation of COD emission performance value.Comparison was made with the traditional methods of pollution discharging coefficient, quota standard, and recommended value of the interim measure,the performance values were determined,which could really reflect the emission status of the papermaking enterprises . The recommended values for waste paper, old corrugated paper, old cardboard box, and wheat straw pulp and paper companies were 3162 g/t, 3349 g/t, 1744 g/t, and 3600 g/t, respectively, with the qualification rate of 50%~57%.Regarding to the difference of environment capacity in various regions, a method was proposed for setting special discharge performance values by using quota standard method.
