Proposed Scenarios for Total Emissions Control of So2 Emissions during the Tenth Five-year Plan in China

China continues its strategy of total emissions control (TEC) or total load control for SO2 in the Tenth Five Years (2001~2005). This paper will analyze the status of SO2 TEC in China during the Ninth Five-Years (1996~2000). Based on the results of the analysis and the theory of divisional air resources, this paper will study the target of total SO2 emissions nationwide and its allocation for different regions during the Tenth Five-Year Plan (TFYP), then propose an initial scenario for the TEC of SO2 at the national level and for the SO2 and Acid Rain Control Areas (the “Two Control Areas”) during the TFYP. Based on the study conducted by the authors, we recommend controlling the total emissions level of SO2 to 19 million tons by 2005. The allocation of a SO2 TEC target to a region provides a permitted level of SO2 emissions for the pilot regions where SO2 emission trading is being conducted.
