In order to grasp the variation of domestic air pollution emissions, EPA had planned to update national emissions by a 3-year cycle. 2000 base year Emissions were finished in year 2003, and Emissions for 2003 is updated by year 2006. This project is a 2-year period continuity project for preparation of the 2003 emissions. [TEDS6.0] version’s databank of Taiwan emission data system for 2003 draft emissions has been prepared in 2005 and is finalized in 2006, which is called [TEDS6.1] version databank. The major works in this year are to review the extraordinary emissions data and to modify the errors in [TEDS6.0]. Time series data and speciates data for emission sources in recent years are also collected, which can be used to support the temporal, and speciation of emissions for modeling.Besides the estimation of 2003 emissions, updating emission trends for 1987~2002, projecting emission growth from 2004 to 2021 base on year 2003 and comparing the emission reductions of different control scenarios are also parts of the work items of this year’s project. Totally 3 reduction scenarios are compared. The evaluation results could be used as a reference for control strategy planning for future years.In support of EPA’s administration affairs, such as air degradation estimation(base on [TEDS5.1] version’s emissions) for 1994~2005, air quality improvement score calculation for SIP assessment of local BEP and modification for emissions web page are also conducted in the project.
