Introduction
Scandal of Volkswagen emissions happened in 2015 in the month of September. The
EPA (Unites States Environmental Protection Agency) stated violation notice for Clean Air Act
to the German automaker in the Volkswagen group. EPA found out that the company introduced
TDI (Turbo Direct Injection) engines so that they could activate their control of emission in the
testing phase (Rhodes 2016). Introducing of TDI stated about emitting 40 times less NOx
compared to real driving. In total, the company implemented this TDI in about 11 million cars all
over worldwide. VW after implementing the TDI started a wide marketing campaign stating that
its new launched cars emits less emission. The below statistics shows the emission of nitrogen
