Taiwan Emission Data System (TEDS), as basic information to national emission control, is reviewed and updated every three years. And, the resolution is down to county’s scale. The focus of the project this year is to produce the new inventory of TEDS based on 2013. The data of this inventory provided to several authorities includes emission statistical information of counties and industries, predicted trend of emission w/o control, and emission data base of 1km x 1km with time profile. The main achievement of this year also includes:
1. Finish the calculation of air pollutant emission of 2013, and improve the estimation of emission from ships, airplanes, and restaurants. The inventory contains point, line, area, and bio sources. Criteria air pollutant species, including TSP(primary), PM10(primary), PM2.5(primary), SOx, NOx, and NMHC, are estimated with total amount of 392,536 tons, 170,915 tons, 80,931 tons, 125,649 tons, 406,617 tons, and 646,890 tons.
2. Database from Vehicle detection system (VD) of Freeway Bureau was adopted this year to improve the estimation of emission from freeway. The results show that the discrepancy to previous method is still acceptable.
3. Data of CEMS (Continuous Emission Monitoring System), VD of freeway, and airplane schedule from Taipei, Taoyuan, and Kaohsiung airport, are adopted to improve the hourly profile of emission strength.
4. Control scenarios are quoted from the EPA, and SIP of air basins or counties. In case of implementing all control strategies, the estimated reduction of emission in 2021 are 25,152 tons for TSP, 14,963 tons for SOx, 26,718 tons for NOx, and 458,459 tons for NMHC.
5. Collect QA/QC information of inventories overseas to improve that of our previous TEDS, and implement the QA/QC structure and process of point, line, and area sources.
6. Concerning Impacts from air-pollution-control charge of stationary and mobile sources, the CMAQ modeling results revealed except for Keelung City and Taipei City which were mainly affected by mobile sources, other districts were fairly affected by stationary and mobile sources, and the Kou-Hsuang/Ping-Dong area was mostly affected by stationary sources.
7. Updating the county/city emission reporting system: including a) technical support of 2015 county/city emission control projects; b) review, evaluation, and advises to 2015 emission control projects; c) elaboration of evaluation standards for 2016 emission projects.
8. 2014 green national product (GNP), including newly added product from PM2.5 emission, is prepared, and provided to the Directorate-General of Budget, Accounting, and Statistics.
9. Maintain and update the web site of “Air Pollution Inventory Query System”. Elaborate the structure of next version emission inventory web site. Accomplish the web-site contents of estimation teaching of new emission sources, activity of emission, and space allocation index. Continuously collect related information of emission web sites overseas.
10. Finishing new version of TEDS technical manuals which include estimation formulas and references of stationary, mobile, area and biogenic sources; Four training conferences held in Taipei and Taichung and elaborating updates of new version TEDS.
