The objective of this study is to determine the magnitude of mitigation possible in the transport sector by 2030 considering low carbon policies investigated for implementation or proposed to be implemented or in individual countries. This study is the first known attempt to compare different transport related INDC scenarios against the IEA 2DS, which is generally recognized as a reference scenario for low carbon development within the transport sector. The report assesses a BAU scenario, as well as two hypothetical variants of LCS (average and aggressive) based on available mitigation potential studies, and three different variations of INDC transport related targets.
