Since 2015, the EPA has implemented the CO2 emission standards for passenger vehicles this project was commissioned by EPA to execute auditing on CO2 emissions reporting from vehicle manufacturers, new vehicle random audit testing and labelling check etc. administrative tasks. In addition, the vehicle CO2 Reporting management system has been integrated with certification database, established interface among BOE and MOTC databases, and expand the functionality of vehicle brand lists and new vehicle random audit tests to be electronically accessed to simplify certification process for manufacturers and improve our administrative efficiency. First this project has proposed the draft of CO2 emission standards for light duty trucks according to current domestic vehicle industry status; performed evaluations on the implementation viability of long term target CO2 emission limit values; collect and survey new vehicle management control strategies, eco-driving promotion status and achievements on the transport sectors domestically and abroad; also proposed timelines for the subsequently domestic short term and mid-term CO2 reduction strategies and policies. Consider that in the future the international countries would adopt the world harmonized light duty vehicle test procedures (WLTP). To compare the difference of test results on exhaust emissions under WLTP, and certification recognized NEDC and FTP test procedures, 33 correlation tests were being performed to investigate their conversion factors. The results have shown that, under the same road resistance the CO2 emission values from compared driving cycles are highly related to each other and the PM emission between WLTP and NEDC is moderately correlated. In addition this project also has performed pilot studies on the regulatory requirements for measurements related to exhaust emissions from real road field tests. Under the same test conditions with different driving situations, the difference of test results were within 2 standards deviations and deemed as highly stable. Further to investigate the factors that could affect CO2 emissions from vehicles which include acceleration throttle control, engine rpm and vehicle speed, and the investigation results show that 30% more CO2 emissions would be exhausted by drivers with higher fuel consumption tendency compared to normal drivers. As to the task of eco-driving promotion, in addition to update the Eco-Driving information website, this project has held 10 training courses with 1,419 person/even participants. Edited the training materials and promotion videos on how to perform the Eco-Driving on Buses, this project also proposed its planning of introduce simulation software into Taiwan, performed evaluations on the viability to adopt eco-driving into driver license tests. Finally, to communicate with international organizations, the project execution entity (ITRI) has invited one expert from the US Argon vehicle test laboratory to give lecturers; co-signed Memorandum of Agreement on Eco-Driving promotion cooperation with the Korea Transportation Safety Authority (KOTSA) to promote continuously the eco-driving related tasks through information and experiences exchange with both countries.
