The emission factor of Tier 3 level is necessary to establish a policy for reducing GHG emissions and to promote it efficiently. In the passenger vehicle, the GHG emission factor was developed only prior to 2009, it is necessary to develop new GHG emission factors. This study was carried out for development of Tier 3 level GHG emission factors reflecting emission trend of passenger vehicle during the latest 3 years. To ensure reliability of developed new Tier 3 GHG emission factors, all test results were obtained through statistical analysis and the final regression model was determined by comparing the coefficient of determination. To review the accuracy of test results, uncertainty review was also carried out. New Tier 3 emission factors developed through this study will be utilized for national GHG emission estimation and policymaking.

As customer consciousness about the environment is getting higher, people has been growing very attentive to auto-cabin indoor air quality as well as indoor air quality of houses. Ministry of Land, Infrastructure and Transport has arranged and enforced the world’s first management standard for auto-cabin indoor air quality of newly manufactured vehicles at government level in order to protect consumer’s safety and health due to Sick Auto-cabin Syndrome, which is caused by harmful substance emitted from the interior material of newly manufactured vehicles. Currently, we reinforce the existing management standard for customer protections and we are doing research in order to cope with the international standardization of auto-cabin indoor air quality of newly manufactured vehicles in advance. Meanwhile, there are no measurement methods about auto-cabin inflow of vehicle exhausts and acceptable criteria for harmful substance all over the world, even though consumer anxiety about problems caused by auto-cabin inflow of vehicle exhausts has been increasing. Therefore, we are now studying on creating a reasonable and objective standard for auto-cabin inflow of vehicle exhausts. Through this study, we would like to introduce policy and research position about auto-cabin indoor air quality as customer concerns and the necessity of establishment of countermeasures relating to the improvement in auto-cabin indoor environment have been gradually increasing for the safe driving and national health care.

In the automotive industry, hybrid electric vehicles have been developed and released continually to meet emission regulation and fuel-efficiency. Therefore, we need to research GHG emission factor for hybrid electric vehicles to reduce it’s GHG emission. Hybrid electric vehicles use engine and motor multiply. Existing GHG emission test method is unsuitable for development of GHG emission factor for hybrid electric vehicles. Because It has different GHG emissions as the ratio of the engine and motor driven although vehicles use same motor and battery. In this paper, test method would be presented to develop GHG emission factor for hybrid electric vehicles, and we want to take advantage of road sector’s GHG reduction policy formulation and evaluation, etc...
