The transportation sector is one of the most significant sources of anthropogenic greenhouse gas emissions. Inorder to mitigate climate change, it is important to apply effective and immediate policies to reduce the trans-portation sector's emissions. This study aims to: (1) define the dimensions of the transportation sector, such as itsenvironmental, economic, social, and political elements, and (2) investigate how they relate to climate change, inorder to assess potential mitigation scenarios and policies that could reduce the sector's contribution to climatechange. First, sector-related variables were specified using expert opinions and a literature survey. Relationshipsbetween the variables and the associated intensity values were then identified using document coding, as well asby gathering expert opinions through a workshop. A fuzzy cognitive map analysis was then conducted toinvestigate the relationships between the variables and the resulting impacts by the transportation sector onclimate change. A scenario analysis was also conducted in order to identify the most effective policies in reducingthe impacts of transportation on climate change, at both the local and global levels. For the scenario analysis atthe global level, projections by the International Energy Agency were analyzed through the model. The localpolicy suggestions developed by Turkish authorities were also evaluated using scenario analysis.
