ABSTRACT |
In order to build and efficiently implement a policy to reduce greenhouse gas (GHG) emissions, a Tier-3 level emission factor is necessary. The GHG emission factor for the passenger vehicle segment was developed by the Korean Ministry of Environment up to 2009, after which the Korean Ministry of Land, Infrastructure and Transport has been conducting the task. This study aims to develop a Tier-3 level GHG emission factor reflecting the emission trends of passenger vehicles by fuel type and size class from 2010 to 2018. To secure the reliability of the newly developed Tier-3 GHG emission factor, all testing results were obtained through statistical analysis, and the final regression model was selected through a comparison of a coefficient of determination (R2). A review of the measurement uncertainty was conducted in order to examine the accuracy of the test results. The new Tier-3 emission factor developed through this study will be used for calculating national GHG emissions as well as establishing policies for the issue. |
